For future questions :
"Help me to solve this problem" is not a qualified description or a title with sense.
Perhaps you think about that ...

Ralf Meier 21-Mar-23 9:22am View

I'm sorry ... but for me this code-snippet isn't useful for having any idea about your problem ...

Ralf Meier 20-Mar-23 5:37am View

👍

Ralf Meier 20-Mar-23 5:29am View

Because, as Dave allready mentioned, Screen.AllScreens.ToString return a string into ScreenCount.
I have no idea what happend if you use the sample from Grame_Grant with a string - but I suppose that you allways will work with Screen(0) - that means your primary Screen.
Perhaps you look carefully at the sample you got and try it with the posted version ...

Ralf Meier 20-Mar-23 5:29am View

No ... sorry ... I pushed the wrong Reply-Button.
My Reply should point to Hannes who is still on his "own" course ...

Hi Griff,
your answer is, as everytime, quiet correct ... but I suppose that it isn't useful for the OP because there are a lot of basics missing ...

Ralf Meier 14-Mar-23 13:29pm View

I'm sorry, Bradley ... but I see absolutely no difference between the Solution 2 and 4 and I also can't see why one of these Solutions is better than the other because both are using the same mechanism.
In fact it is no Problem to give an additional answer to an old question if it's different and/or a complete new approach - but in this case I see more the point which is called "Reputation Points Hunting" - and that is a very often used practise in this Forum. Perhaps you take a look at the "community" and there to the "Spam and Abuse watch".
But also for me there is no need to discuss this further - sorry ...

Ralf Meier 11-Mar-23 15:44pm View

It's the same than Solution 2 - and your Reply goes to a more than one year old reply from me ... 🙄

Ralf Meier 10-Mar-23 3:08am View

I agrre completely with those who have written before - but to give you a hint :
In the last sentence of your reply your have the answer to your question - what do you think : how could you get the Discount-percentage ? Have you ever heard from dividing ?

Ralf Meier 2-Mar-23 4:57am View

That is basicly the same question as asked here :
https://www.codeproject.com/Questions/5355899/Csharp-listbox1-all-items-have-picturebox-pictureb

Ralf Meier 27-Feb-23 15:44pm View

I agree with Maciej - even when there are lot of problems for you it is absolutely necessary that you are able to describe your issue an ask a useful question. Try to do it step by step ...

I don't agree with Member 15627495 - VB.Net isn't harder to learn as C# - in my opinion it is easier for to get q starting point ...

Ralf Meier 27-Feb-23 7:27am View

If you really want to get Help or Assistance YOU should give (like Andre Oosthuizen has mentioned as a Comment) MUCH MORE INFO ...
Your Comment here isn't a useful Info (for me) ...

Ralf Meier 20-Feb-23 15:30pm View

at 1st :
I would code "if not flagDataLoading then ..." instead of "if flagDataLoading = false then ..."

But ...
when do you set flagDataLoading to True ?
I suppose that there is the problem ...

Ralf Meier 15-Feb-23 4:47am View

OK ... and when you put this inside a Loop you get the same result - it is the same procedure - the only difference with the Excel-Sheet is that you have done this Loop manually ...

Ralf Meier 11-Feb-23 3:34am View

??? ... and how did you realized it in Excel ???

Ralf Meier 4-Feb-23 12:00pm View

+5 for that ...

Ralf Meier 4-Feb-23 11:57am View

I don't understand your reply - sorry ...
The work could be done by the code and if you read my answer carefully you could see that the sentences 3 and 4 describe the code you need.

Ralf Meier 30-Jan-23 12:50pm View

I agree with @Grame_Grant - somewhere in your code (perhaps the Countdown-Display) forces an Invalidate of the complete Form.

Ralf Meier 26-Jan-23 18:04pm View

without understanding the sense of your question :
- take the Byte-Part (for example 1A) from the string
- build an integer-value from it
- divide it by 2 or do a shift right
- rebuild a string-value from the new byte-value

Ralf Meier 26-Jan-23 5:44am View

Perhaps you can explain why you think that your "Solution" is an acceptable answer to this nearly 9 years old question ?

Ralf Meier 18-Jan-23 5:52am View

how did you have adressed the Document itself ?

Ralf Meier 13-Jan-23 10:45am View

I 've seen it -there are no more ... ;-)

Ralf Meier 13-Jan-23 8:48am View

Sometimes I also have no idea where to start - so I agree with Grame_Grant.
Of course ... this is a quiet easy question and also of course ... with googleling it would be very easy to get also this solution.
So ... I would downvote the question and not the answer ...

Ralf Meier 12-Jan-23 14:15pm View

Basicly I agree with Gerry ...
What we do here is helping those who stuck at a specific point. Perhaps it is possible to help you ... but without some code from you and a idea what you want to have it is impossible (for me) - or in other way : we don't sit in front of your PC and can't see what is happening.
The concept for game rules (generally) are the rules of the game itself - if you want to create a kind of KI it depends primary also on this rules ...

Ralf Meier 12-Jan-23 11:46am View

I don't see a question ... or is it the ask for "do the remaining work for me" ?

Ralf Meier 9-Jan-23 16:49pm View

If ypou don't understand what I mean I must ask you for your knowledge. Did you understood any of that what I've written ?
For example derive or customizing ?

Ralf Meier 6-Jan-23 13:22pm View

Sorry - this code doesn't help ... :(
What I would do :
- create your owh (customized) Picturebox which derives from Picturebox and has some additional Properties as :
- Back-Image (which as to be seen when the Picturebox is not activated)
- Active-Image (which is to be seen when the Picturebox was activated)
- Active-Image-Code (same Images has the same code)
- Status (tell you that the Picturebox was activated)
and also additional Methods as :
- Change_to_Active_Image (when Clicked change the Image from Background to Active)
- Change_to_Back_Image (when called change the Image from Active to Background)
- now assign the Images (randomly) to those Pictureboxes and give them a code for identifying
- if you click the 1st PB memorise it and it's code
- when you click the 2nd PB memorise it and it's code
- compare the both codes - if they are matching switch them to unvisible
- if they are not matching change both to the Backimage
- the game is over when no PB is visible

Ralf Meier 5-Jan-23 13:43pm View

The Description from Griff for me is quiet clear - but it seams not for you ...
I suggest you provide some of your code because without it it's complete senseless to give more advises.
I suggest also that you read the solution from Griff once more and this time more carefully ...

Ralf Meier 13-Dec-22 11:54am View

OK ... very good ... that seems to be exactly (or nearly) what you have asked for ...
Since I am a kind of collector it is very interesting for me - who knows when I need something like that by myself ...
Thanks for your Reply :)

Ralf Meier 12-Dec-22 11:17am View

Thanks for the Sample - I will take later a deeper look on it ...
The posted Solution I found (on CP) while looking for a complete different approach ...

Ralf Meier 12-Dec-22 8:05am View

I have posted a way to a Solution for you ...

Ralf Meier 12-Dec-22 7:02am View

you could be right - it seams to be a mix between C# and VB.Net ... (but perhaps it could be modified)
But now I have a little time - so I will try it by myself. If I get a Solution I will post it for you ...

Ralf Meier 11-Dec-22 11:56am View

it looks good - you should provide it as a Solution ...

Ralf Meier 11-Dec-22 7:56am View

Complete correct.
Wheen I do this I normally scan the Controls-Collection for the names and add them to a Listbox inside my Form (so I could see the Names) - often the Name itself says all about the Function of the Control. If not you should do the same with the Types.
I'm very interested on your progress - so please hold me informed ... ;-)
And of course if there are further questions ...

Ralf Meier 11-Dec-22 6:54am View

As I wrote before :
You must use Reflection. Each Control has a Controls-Collection which holds all Sub-Control inside it (if there are some). Now what you have to do is : iterate through this collection and find the Name (and by this also) the Reference from the Tabcontrol. But perhaps (that could also be possible) the control is the TabControl (that means derives from it).
If you have the TabControls Reference you can add a new TabPage to it.
How familiar are you with doing something like this ?

Ralf Meier 11-Dec-22 6:35am View

Basicly I can imagine that the Solution from Mike is working - but there is a lot of knowledge neccessary to do this.
In the past I often modified the windows-delivered Editors but mostly to exclude given controls or functions - but I suppose that the other way round is also possible. For this you need to know the content of the UI - that means : what is the Name of the Tabcontrol and where is it located. Now you can perhaps add another Tabpage to it with the content you like to have. The functions of your new Tabpage must deliver the selected value to the Return-Parameter from the original UI - for this you need to know how it is done. I think that this is the most problematicly part (and I have no idea how it could be done).
If you want to have this special function ... why don`t you create you own ColorEditor which works like you want to have ...?

Ralf Meier 23-Oct-22 6:45am View

How does the data inside the CSV-File look like ... and how should it look inside the DGV ?

Ralf Meier 20-Oct-22 16:45pm View

use the "improve question" widget to show the actual code - but not as "something like this"

Ralf Meier 20-Oct-22 9:17am View

But independant from that ... the code, like it is posted, makes no sense and I suppose that there is also an Event-Problem (an Operation is started before it should be startetd) ...

Ralf Meier 20-Oct-22 2:52am View

... and also makes no sense at all ...
Perhaps you post us the correct code for suggestions ...

Ralf Meier 19-Oct-22 10:48am View

Show the complete code from this ... and tell when it is called ...

Ralf Meier 17-Oct-22 2:30am View

Hi ...
I'm glad to see that you have accepted the solution.
If this answer is working for you please be so kind and rate it.

Ralf Meier 17-Oct-22 2:27am View

Basicly, when working with a Com-Port, you should allways know how the communication-protokoll is. That means : what is the request und what is the answer. If the answer is variable you normally get this information from one of the first bytes of the answer.
In the moment I don't know how to give you more help ...

Ralf Meier 16-Oct-22 10:24am View

I'm not quiet sure if I had complete understand your problem - but perhaps :
If you use the DataReceived-Event from the Com-Port you should realize that this Event is fired with the first incomming Character - that means that you should check if all the Characters you are awaiting are inside the Receive-Buffer - that may be a time later.
Baiscly you could check how many Chars are inside the Buffer before do anything further ...

Ralf Meier 29-Sep-22 6:10am View

You should give much more Information - either about your control and also about the code you are using ...
Without this it is impossible to give useful advises - sorry

Ralf Meier 11-Jul-22 3:57am View

you should 1st identify what is one weighting-sequence - I suppose that each time you get a string from your unit it is the actual value. So I suggest you not append your textbox (richTextBox1.Text += ...) but assign to it (richTextBox1.Text = ...).

but ... what device you are using - I think that your "problem" is to be solved with paramters of the device ...

Ralf Meier 29-Jun-22 3:28am View

also it's not complete that what the OP has asked for.
In my opinion the 1st Solution from Griff was the best ...

Ralf Meier 2-Jun-22 8:29am View

you want to have your graphic with more than one String in it ...?
or do you want to print your string inside an area with more than one line ? For example like this :
this is
my string

Ralf Meier 28-Apr-22 8:29am View

I don't understand ... try to explain the relationship and the maximum content.
I suppose that you will need a main-class, which holds the properties, and some sub-classes, corresponding to the properties ...

Ralf Meier 19-Apr-22 9:31am View

you have a kind of Line-definition : y= m*x + b
the only thing you need to do is to check how much of the point-pairs have the same Line-definition / matches to one line-definition ...

Ralf Meier 19-Apr-22 8:43am View

do you know the Specification of the Line you are searching for ?
Or the other way round : with your 1st sample you work with the line (1,1 - 2,2 - 3,3) - who says that this is the right line ? the right line could also be 1,1 - 1,4 and then the 2 points between are wrong ...?
the same with the 2nd line ...

Ralf Meier 19-Apr-22 8:38am View

Hi Eddie,
I have to say that I'm not quiet sure at the moment if the KeyPressed-Event is exactly the right approach (in the moment I'm not able to look for it). If it is right you will get the Enter-Key as possible KeyCode-selection. Otherwise you should look for what Richard has mentioned - the KeyDown-Event. Also there you have EventArgs which gives you much more Info than the "Standard"-EventArgs - but you are allways able to select that because all Special-EventArgs are deriving from this class ...

Ralf Meier 15-Mar-22 8:00am View

To answer your question in your reply (to Griff) : Yes i did ...
Perhaps you haven't had any idea - but in this case you should give much more information. You did nothing of that - no ground to start from ...
And ... for me the answer you gave to Griff was abusive ...

Ralf Meier 15-Mar-22 4:17am View

Think about what you write and don't be abusive ...
Of course you will get an answer if you give information where you stuck - but what you have done is : "do the work for me ..."

Ralf Meier 24-Feb-22 15:05pm View

Thank you, Maciej ... :)

Ralf Meier 26-Jan-22 4:07am View

Congratulations ... you have allready answered a question which ist more than 10 years old ...
Also an answer is allready given - more than 10 years ago ...

Ralf Meier 13-Jan-22 9:34am View

I suppose that you look at it the wrong way round ...
If you have a UserControl which has several other Controls in it - why you don't give the UserControl new Properties which work with the Properties from the Controls inside which could by changed by the User.
I suggest you should be more specific ...

Ralf Meier 2-Dec-21 6:20am View

Please don't answer a more than 5 years old question with an answer which is allready given ... (see both Solutions before)

Ralf Meier 2-Sep-21 9:03am View

Which Property do you mean exactly ?
Do you have set the DesignerVisibility to DesignerVisibility.Content at the Property-Attributes ?

Ralf Meier 27-Aug-21 15:14pm View

I agree completely with Bill because your own desciption says exactly what has to happen - you only have to create a code from it.
To give xou a little start :
- the Selection of you Combobox should depending on the Seletion assign something.
- the Button, if pressed, has to work with that what was previously assigned.
Perhaps you give it a try ...

Ralf Meier 17-Aug-21 5:41am View

actually have created a Solution - which isn't one ...

Ralf Meier 3-Jul-21 13:21pm View

Sorry Richard ;-)
the 1st answer has the wrong average - it must be 7 and not 7,5 ...

Ralf Meier 3-Jul-21 2:44am View

No ... sorry ... give it a try - it's easier as you think.
If you have some code which makes problems you are invited to come back and ask something ... but not "please write the code for me" ...

Ralf Meier 2-Jul-21 5:41am View

Excuse me ... what part of my description is unclear for you ?
Don't you know how to handle the SPLIT-Function ? Or to handle Array-Elements ?

Ralf Meier 28-Jun-21 5:21am View

I asked you to describe what should happen - as you see by the answer of OriginalGriff your code itself makes no real sense.
So what should happen ?

Ralf Meier 28-Jun-21 5:14am View

Perhaps it is easier if you try to describe what you want to achieve ...

Ralf Meier 28-Jun-21 4:13am View

If none of the given answers are matching to your issue you should think about the description of what you want to do.
Perhaps you should improve your question with much more information - for me it sounds that you want to have sub-items to your items ...?

Ralf Meier 28-Jun-21 2:50am View

Hi Griff,
the Brackets ? Right ?
But you are right - today it's really very early in the morning ... ;)

Ralf Meier 20-Jun-21 3:36am View

It is like Patrice allready has mentioned : you should set a Breakpoint (perhaps at the line 'TextBox2.Text = ArrayTag(2)') and look with the Debugger what REALLY is inside ArrayTag - I suppose that you will see that there are only 2 Elements inside ArrayTag (Index 0 and 1). Give it a try ... ;-)

Ralf Meier 11-Jun-21 4:08am View

Initilized means that the Variable "exists" - if we speak about a Variable. If we have a Class-type you only have a placeholder - that doesn't mean that the Variable is instanced.
If you want to have a defined content you have to do it. If we speak about a (more or less) Standard-Variable you have to assign it. If we have a Class-type it could be done with the Constructor (to Default) or with a customized Contructor (as in your sample above) to special values.

Ralf Meier 11-Jun-21 1:28am View

As Richard wrote in the other Solution : if you want to have a defined content you are responsible by yourself to ensure that.
I would never let a Variable unassigned - but that's my 2 cent ...

Ralf Meier 10-Jun-21 4:22am View

I'm sorry - I refered to your Class-Example ...
The Struct must be initialized when used as a Variable (perhaps with the Constructor of the Class which uses it)

Ralf Meier 4-Jun-21 3:37am View

it will be helpful to see the code from the method "CreateRoundRectRgn" - perhaps you improve your question (use the widget "improve question") and provide this missing code ...

Ralf Meier 1-Jun-21 14:17pm View

+5very interesting Solution.
I never thought that it could also be realized in this way - until today I've allready realized that with "conventionell programming".
Thank for it ... :-)

Ralf Meier 19-May-21 9:06am View

Congratulations ... you have answered a nearly 8 years old question - and this question was allready answered.
Only to get Reputation Points ?

Ralf Meier 1-May-21 15:54pm View

... and what happens ?
Which result do you get ?

Ralf Meier 20-Apr-21 3:42am View

to get a useful answer it's very necessary to give information about your issue AND information where you stuck.
Apologize ... but for me your question is complete un-understandable and senseless ...

Ralf Meier 15-Apr-21 8:44am View

If you have a Question then ask it as Question and do not add it as Answer to an existing Question ...

Ralf Meier 28-Mar-21 6:50am View

not quiet correct ... I suppose.
As I see each incomming sequence is ended with a LF - I haven't seen that before.
Your Solution might work (in the moment - but could make an error in future). You look if your incomming sequence contains a LF - I would change it to that your incomming data must End with LF ot ENQ or EOT. Also you should work only with that String-part which is ended with one of these Chars ...

Ralf Meier 26-Mar-21 13:43pm View

Not really. It depends on your Communication-Protokoll.
The Serailport has the Property BytesToRead. This Property gives you the Information how much Bytes are actually inside the Buffer.
If your are awaiting (for exmaple) 10 Chars and there are only 6 in it you should exit the Method - with the next incomming Char the Event raises again.
If the Buffer contains more than 10 Chars - but you need only 10 - you should not ReadExisting - read only those which are needed by you.

Another Approach could be not to use the DataReceived-Event. You could also use a Timer (for example each 100 ms) and check there if the count of Chars are matching to what you need.

Give it a try - you know much better than I what is needed and when ...

Ralf Meier 19-Mar-21 9:04am View

There is no real difference to the code from the OP. It must work with .Value as well ...
I suppose that one (or more) of the source-Cells doesn't exist ...

Ralf Meier 15-Mar-21 11:07am View

OriginalGriff exactly wrote what your problem is - your Exeception says : "expected Typed is DateTime" - you give it a string ...
That means in other words : you want to get a car - and the seller gives you a cheese.

Ralf Meier 13-Mar-21 10:14am View

Hi Bill,
I agree with you ... and I doesn't meant OriginalGriff as reference - I'm definately in the position to see there a difference ... :-)
I think you have also read the rest of my comment - I also try to be serious too ...

Ralf Meier 13-Mar-21 7:06am View

I don't understand the calculation within your provided code. I suppose you try a kind of scaling.
But when you ask for Screen.PrimaryScreen.Bounds.Height==600 - why do you divide inside your scaling with 768 to get your faktor ?

Ralf Meier 13-Mar-21 7:01am View

@Bill:
I have to break a stick for Patrice. This is an often given answer (as well as Solution) to questions like this. I you make a downvote here you must make this by each and every question which gets an "Solution" like this.
Of course - you are right - it's not a Solution, the Solution (in my opinion) could one if the OP gives much more Information about his problem. I also stuck at the point "conversion Symblos to Numbers" ...

Ralf Meier 11-Mar-21 14:00pm View

Excuse me ...
tabselector.SelectedIndexChanged ?
That Event normally should come from the TabControl itself ... what is "tabselector" to you ?

Ralf Meier 11-Mar-21 13:55pm View

I'm not using your development system - I use a much older version ...
As I understood the Behaviour don't effect the Tabs itself but the Controls inside them ...
But if you don't relocate them there must be another relationship between them ...
Do you have AutoSize enabled and Labels or Textboxes grow with the assigned Text-Strings ?

Ralf Meier 11-Mar-21 13:51pm View

Thge OP (and me too) also come from Germany ...

Ralf Meier 11-Mar-21 12:42pm View

Have you used the Dock-Property of some or all of the Controls of the other TabPages ?
I suppose that you haven't a method which calculates the location for the Controls ?
What are the "many changes" you made to your Application ?

Ralf Meier 11-Mar-21 9:07am View

Why don't you listen to what Richard wrote to you ?
Don't you know the difference between those Types of Variables ?

What I don't understand :
You have a String why those values inside. Why do you first convert it to an Array and after this want it back as a string ?
If you can answer this I suppose you find the real answer by yourself ...
sorry for that ...

I'm wondering that I haven't heard anything from you until now. In my opinion this must be the Solution for you.

Ralf Meier 1-Mar-21 11:32am View

OK ... you were some seconds faster ... ;-)

Ralf Meier 1-Mar-21 11:32am View

Perhaps you shouuld write something more about what you are doing there ...
Label.Text contains allways a STRING - the same is a Textbox - Textbox.Text is also ALLWAYS a string.
But perhaps your string has a numeric format ... so if you want to compare them you have to convert them to the right type.
What you have done is to be seen in your code-snippet - you made a string from a calculation ...

If you want to compare numerics you should use numerics.
Compare Doublke with Double - for example.

Also ... it doesn't makes any sense to assign strings to your Chart as X-Y-values. Also at this places it is necessary to assign numerics ...

Ralf Meier 1-Mar-21 6:01am View

of course you have seen that this question is nearly 10 years old ...?

It is a kind of Statemachine - I made it as follows :
The first time is your time before showing the Messagebox.
The next (2nd) time is for showing the Messagebox.
the 3rd time is the time you cvanmn see the Messagebox before it shuts down automaticly ...

My Timer-Tick was 1 Second - so that is also the base of this times.

Hi Rick,
where is the difference between your code and mine ?
Of course ... I only provided the Timer-part assuming that the rest is still working ...

Thanks a lot for your efforts - I will try it later and give a Feedback ... but basicly (first look onto it) it looks good :-)

Ralf Meier 13-Feb-21 17:13pm View

OK ... I think now I understand ...
When you start your Application for example a 10 am it also executes the alarm and stop itself because 10 am is after 8 am - am I right ?
If Yes you have to check when starting your application if your current time is before the alarm-time or after. If it is after you set a flag which prevents the execution of alarm inside Timer1_Tick. But inside the Method Timer1_Tick you reset the bit if the current time is before alarm-time.
Thats all ... ;-)

Ralf Meier 13-Feb-21 11:18am View

And your problem is ?
I suppose your Application exits without starting the Alarm - right ?

Ralf Meier 13-Feb-21 11:15am View

I know that this is not an easy question ...

I don't have implemented IDesignerHost ... but I created a customized ParentControlDesigner to my Control - I suppose that goes in the same direction ...
With the basic functions of the ControlDesigner I'm very familiar - only this part is a black hole for me ...

Ralf Meier 13-Feb-21 10:43am View

Hi ...
that is nearly the same as Maciej allready suggested to me. To clarify : my issue is the DesignTime-functionality - there it must work. The Drag-Events from the Control during Runtime will work (I'm sure).
During DesignTime (I suppose) the ParentControlDesigner must be the right address - but all my tries there (without any usable documetation from Microsoft or others) did not solve in any success ... :-(

Ralf Meier 13-Feb-21 9:29am View

It was only a Suggestion ...
But independant :
You should compare if DateTime.Now is greater than your preset-time. Therefore you should compare DateTime with DateTime - you could also set your preset-time as DateTime ...
So make your Variable eight to a DateTime and set it like this - then the compare will work ...

Ralf Meier 13-Feb-21 6:49am View

I suppose this is a question ... so ... if you want to get an answer you should ask your own question an not post something as Solution.
Give it a try ...

Ralf Meier 13-Feb-21 4:03am View

I tried your suggestion but it leads to nowhere ... The point is that in DESIGNMODE my Control doesn't ask for the drag-drop. What I tried now was do enable the functions with a customized ControlDesigner - here exists the method GetHitText with which you can activate underlying parts of the Control during DesignMode (for Example open a ComboBox or Switch Tabs of a TabControl and so on - I have a lot experience with that). But that doesn't work ... :-(
So I tried do do the same inside the customized ParentControlDesigner - there are also existing methods for Drag-Drop - but without success. I think this is the right place but I don't have useable Information about that - at this point the Internet AND Microsoft is very very poor.
The only possible Solution I found until now is a combination of a control with a Panel inside. Of course ... I could do it this way and that will work ... but that seams also very poor to me ...
And CodeProject also doesn't help me to get a step foreward ... :-(

Ralf Meier 12-Feb-21 18:19pm View

OK ...
How does your String-Value look like when you read it from the serialport ?
How does your Interger-Value look like when you read it directly from the Serialport ? What is the difference between that value and the one which is send by the Arduino ? ... and what does the Arduimno send ?
You see - that is to less Information you gave to us ...?

Ralf Meier 11-Feb-21 13:09pm View

Thanks Maciej - I will try that later ...
But in my opinion is a functionality which comes from the ControlDesigner and not from the Control itself.
I can actually drag other Controls inside my Panel - but I can't prevent that at special (or better unwanted) positions ...

Haven't you used ProvideProperty until now ?

Ralf Meier 29-Dec-20 8:59am View

No problem ... and to ProvideProperty I can't give a Description and a Categorie directly - but perhaps there is a way I haven't found with Goggle yet ...

Ralf Meier 29-Dec-20 8:50am View

Okay ... sorry ...
I have a Component which uses ProvideProperty and Implements the IExtendedProvider. Those Properties, which come originally from the Component and are "provided" to the other Controls, I want to change the Category and the Description. With "normal" Properties, which directly belong to the Control, it is quiet clear for me.
Do I have explain it better now ?

Ralf Meier 29-Dec-20 8:13am View

Sorry Richard ... but I can't see how this Solution matches to my question.
Your example shows "regular" Properties from your customized Control. I have a Component which provides Properties to other Controls which normally don't belong to them ... here the Component really works with the Data of the provided Properties.

And you have deleted the Code-line inside the Form_Load-method ?
But I'm also a little confused with your descriptions ... which Button from which Form should enable which Button on which Form. I suggest you use unique descriptions.
Basicly your code must work if it's called - but it is possible that another method compromise it ...

Ralf Meier 25-Jul-20 15:18pm View

A link for what ...? Give it a try ...

Ralf Meier 25-Jul-20 13:18pm View

Yes ... of course ... you should now set each new Series to a new (different) color ...
That means : inside your loop you have to do this - for eample with a pre-defined array where the 1st element is Green, the 2nd Red, the 3rd Blue and so on ...

Ralf Meier 24-Jul-20 16:50pm View

at first : to compare DateTime.Now exactly will not work - notice that here are also Milliseconds included. A Match to a Millisecond-Value is nearly impossible ...

Ralf Meier 20-May-20 5:43am View

Ralf Meier 20-Apr-20 5:00am View

Hi,
the decribed behaviour is quiet normal because the Groupbox is NOT translucent. The Control which has the Focus will move to foreground - either the Groupbox (with the Textbox inside) or the DGV. So : let the DGV also be a member of your Groupbox ... OR ... let the Textbox be the member of the Form (to which as it seams the DGV belongs).

Ralf Meier 17-Apr-20 7:20am View

OK ... where do you stuck ...?

Ralf Meier 17-Apr-20 7:19am View

I can't follow you (in the moment) ...
Please explain : what should happen with which action ?
And : why do you have the Textbox inside a GroupBox ?

Ralf Meier 17-Apr-20 4:40am View

So there are some new questions :
- what is the sense of the Groupbox ? Why don't you have the Textbox directly on the Form ?
- Does the GroupBox directly end behind the TextBox ?
- or ... do you want to place the DataGridView over the GroupBox (when under the TextBox) ?
- or ... should the DGV also become a Member of the GroupBox ?

Ralf Meier 9-Apr-20 6:56am View

to complete the answer of Maciej :
- Location is a point inside your Form where the Textbox should appear - this point has to be calculated by you
- SomeNumber is the Number of the Textbox - inside YOUR Loop this Number must be incremented by you

If your code really doesn't work : improve your question with the new Code - completed by the Suggestion of Maciej ...

Ralf Meier 31-Mar-20 16:30pm View

From where does this Hex-String comes ?
What is it's sense ?
The reason of my question is that no Interger-Format is able to display such a great value as it's shown above. Perhaps you don't need the conversion as discribed by you - perhaps you need something complete different as conversion-algorhythm ...

Ralf Meier 27-Mar-20 16:11pm View

Ralf Meier 6-Feb-20 4:51am View

I'm not complete sure but I suppose that at the end of Form_Load the Controls of the Form are instances - not before. I would try it with another event from the Form.
Another point : For me it's allways weird to give a variable the same Name as the Type to which it's refering (For each control as Control ... - better : for each c as control)

Ralf Meier 23-Jan-20 4:33am View

I made this suggestion because some years ago I had the issue to store data from a HMI-System, which was connected to a PLC (both Siemens), to a Network-Drive. Sometimes the Network-Drive was not accessible but Windows doesn't realized that (perhaps because of cached information). With programming I only had the possibilities of VBA. A normal write-access to the Network-Drive causes a very long Timeout which wasn't akceptable - but the directory-read in this environment causes an error which was handlebar for me inside the Script. But additional : I tried to read the directory from a defined subdirectory - not from the root ...
