Hello.
The problem is this: I have two tables:
Requirements(ID_doc, Name_doc, ID_DeliveryType) and
DeliveryTypeCodeList(ID_DeliveryType, DeliveryType_doc).
I put the form fields from the table ‘Requirements’ where the column ‘ID_DeliveryType’ is ComboBox type-a. For ComboBox DataSource I put table ‘DeliveryTypeCodeList’ where column ‘DeliveryType_doc’ is DisplayMember and column ‘ID_DeliveryType’ column is ValueMemeber.
Requirements
--- ID_doc - Name_doc - ID_DeliveryType
________________________________________
-----1--------doc1----------23----------
-----2--------doc2----------23----------
-----3--------doc3-----------2----------
-----4--------doc4-----------3----------
DeliveryTypeCodeList
--- ID_DeliveryType - DeliveryType_doc
________________________________________
---------2--------------poste-----------
---------3---------------fax------------
--------23---------------mail-----------
My wish now is that when I run the program, in the ComboBox it print (descriptive)values from the column 'DeliveryType_doc' (mail, fax, post)!
But it just does not happen?!???
If you have time, there is also the source code of the program: http://rapidshare.com/files/305140006/BugComboBox.rar
or if you want you can see the video where I show that I have tried all combinations: http://www.youtube.com/watch?v=5VK-c39eL-4
THANK YOU!

Noone is going to download your entire project. You have to post the relevant code that sets up the ComboBox and do a better job of explaining what you want. I'm not entirely clear on what the problem is.

|

Watch the video http://www.youtube.com/watch?v=5VK-c39eL-4
and all will be clear.
By the way, there is no code associated with ComboBox.

Apart for not having any code in the project, the WHOLE thing is 160 KB, so why not download it and try what we did.
The project contains only the part that is relevant to the question, and a dummy database that is needed for it.
It contains no code, since we are trying to program the MS way: clicking, dragging and dropping components, without or at least with minimum code written by hand.
That is why we posted the video (11 MB) on the youtube, so people can see what we are trying to do.
So please, if you have an answer, do post it, otherwise, thank you for reading our question.

Because I don't run code I do not trust.
You post the relevant code here in your post in PRE tags...

Dear codeproject.com administrators and members,
A greeting of peace. I hope everyone is doing fine upon reading this forum.
Well, it's really my first time to try Visual Basic .NET, then I realized that not all my previous experience with VB6 will work smoothly in VB.NET. I am creating a simple program that will enter a name in the TextBox and will greet them by using the MessageBox class. But I wonder, since the TextBox that I'll be using is for inputting a name, I want to "trap" all numeric keys in my keyboard, I just don't know how to do it. This is fair easy in VB6, using the Text1_KeyPress(KeyAscii As Integer) subroutine.
Thank you and more power to all administrators and members. God bless. 
Respectfully yours,
MarkSquall

Fortunately it is pretty much equally easy in VB.NET, and in some ways even easier:
This example will actually do the opposite of what you are trying to do, but it is easy to adapt to your needs, and I think it shows how .NET makes certain operations even easier than VB6.
Private Sub Text1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Text1.KeyPress
Try
If Not (Char.IsNumber(e.KeyChar) Or Char.IsControl(e.KeyChar)) Then e.Handled = True
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
A nice little added advantage can be found in the Handles bit: here you can actually add other textboxes, if you want them to behave the same way. (Handles Text1.KeyPress, Text2.KeyPress, Text3.KeyPress)
My advice is free, and you may get what you paid for.

How can I when double click on a node, I can edit it?
I mean the node is a treeview.
Thank you before answering.
I am waiting for your answer.

Handle the double click event, it will presumably be passed the node, so delete it from the Items collection in there.

Handle the double click event on the treeview
use hittest to see if there is a node under the click
Get the node from the hittest
get the parent node from the node
get confirmation from the user
delete the node from the parents node collection

Dear Friends Thank you very much gave the answer
Especially Christian Graus and Mycroft Holmes.
Code is very good. I hope you succeed
|
|

|

You want an example,Or a project for me to upload in this field.
thanks!

You want to edit the label or delete the node itself ?
If you want to enable automatic label edit, try:
TreeView1.LabelEdit = true;
If you want to delete the node, try Mycroft Holmes' post.

Hello!
I have some data and I'm needing to analyze it, like the example:
My Data
Date Time Rate
20081005 00:55 15
20081005 00:56 14
20081005 00:57 13
20081005 00:58 14
20081005 00:59 11
(...)
I need to evaluate how many times the "Rate" is above certain value (10 for example), how long it be above this value. Also I need to register every time in which "Rate" becomes below 6 for more than 10 minutes, and for how long.
Thanks

For starters, VB6 is no longer supported, so perhaps you should consider VB.NET Express.
That said, the way to check your data depends on how your data is stored. If it's in a SQL Server database (or similar) a simple SQL statement would be the best way.
If it's in a text file, you will need to open the file, read it one line at a time, parse the line, count the number of times the Rate is out of the range you are looking for etc.
More info is needed. What have you tried already? Where are you stuck?

I Have this data in CSV files, so i imported them to a DBGrid, i've tried some SQL, but I could only "filter" the results.
I'm gonna consider VB Express 2008.

Import the CSV file to an SQL Server database table and use SQL queries to do it. Download SQL Server Express, it's free.

What does 'not working' mean ? You're just grabbing values from media player, is your computer connected to the internet ? Are you testing with the same CD every time ?
This code copies all the text into a poorly named textbox. Surely you should be putting it into the database in this part ? What sort of database do you use ?

Few pointers:
- Post your code in the code block tags (click 'code block')
- (Like CG said) use some better descriptive control names, textbox1 has no meaning
- You said it worked a few days ago, what has changed since then? (in code or on your pc)
- Have you debugged this, if yes where is it going wrong
- What is going wrong?
- Any error? (post it and the line that is causing the error)
Without this information or a mind reading machine nobody is going to be of much help to you

He/she is spamming the whole site. I read them all - it looks like the code is now returning empty strings. I assume this means that the WMP can't find the internet, can't find the CD in the database, or that for some reason, the WMP version is no longer looking up CD data. Obviously, this person has written next to no code, they just found a snippet that gets the info from WMP.
I am having trouble working out how putting all the text in one textbox, constitutes a database.

its not the connection to the database that is the problem, its the begining thats the problem. right after u insert the cd, it doesnt copy the contents off the cd.

I'm sorry, but this makes no sense at all. Perhaps if you answered my reply to you ? You're not getting values anymore, so what changed ? Is it the same CD ? Is your computer online ? Did your windows media player version change ? If you put the CD in to the computer and run windows media player, does it show the right tracklist ?
Do you have a database at all ?
