Hi !
First, sorry for my bad english, but I'm french.
I try to understand how making a small "code editor" with a richTextBox and I'm currently working on the "line numbers column". I'm using a Panel and GDI for drawing the column and the numbers too because I want drawing them at the same height of the richTextBox line. I can draw them without problem, except when I st my RichTextBox "WordWrap" property at True.
When a line is too many long, she's "splited". I'm using "GetLineFromCharIndex(rtb.SelectionStart)" on "SelectionChanged". So, for example If Ihave 2 real lines, but the first is to many long. So I have 3 lines now.
When I click on the second part of the first line, this return "1" because for the RichTExtBox, the second part is a new Line. 
But I want this return "0" ... I'm on the first "real line", not on the second one.
Is there a way to know when a line is splitted when WordWrap is True ?

I don't believe there is any way to get notified when one line is wrapped: I don't see an event that would report on it.
The easiest course would probably be to keep WordWrap off, and use a horizonal scrollbar; this is what Visual Studio does. The other alternative would be to build a custom RTF text box from scratch and raise an event when a wrap occurs.

If you really had to you could do something like
RichTextBox1.SuspendLayout()
RichTextBox1.WordWrap = false
RichTextBox1.GetLineFromCharIndex(rtb.SelectionStart)
RichTextBox1.WordWrap = true
RichTextBox1.ResumeLayout()
though it seems more like a work around...since GetLineFromCharIndex is really just supposed to tell you what line on the display the char is on, not the line in the text.

Hi William.
Thanks for your trick. This is no really my problem, but your piece of code will be usefull 
My richTextBow is already in WordWrap = False. My problem is if the user write an hml Tag like this
<!-- GOOD -->
<div id="myID" class="myclass" />
<!-- False -->
<div id="myId"
class="myClass" />
Yes I could only check for start "<div" after="" the="" attributes="" and="" alone="" end="" tag="" "="">", but I don't think it's the best choice.

Well, with only the example you've provided, why not just check for the >? You could count how many occurred before the char you're checking.

I am having weird experience with the VBA (MS Access 2007) context sensitive setting for when I try to use it to get a property or method.
For example, I have a checkbox in my Access 2007 form. I want to do something simple like use context sensitivity to show the Value property of my checkbox:
<br />
myChkBox.Value = <br />
HOWEVER before I can finish typing "va", the context sensitivity stops and it won't allow me to auto-complete the word. MORE ANNOYING is the side effect when after i type in .Value and press space, the cursor then jumps back to the "e" in value and removes my space.
This is the same for other variables and objects:
<br />
dim bIsCheckSet as Boolean 'sometimes becomes bIsCheckSetas or bIsCheckSet asB<br />
the problem: context sensitivity (auto-complete) acting weird and seems to have a "time-out" period that is very short.
HELP!

I experienced this issue a while ago when the form was in Form View not Design View. Doing the coding while in Design View seemed to solve the problem for me.

thanks for the suggestion. it did not correct the whacked-out MS behavior i am seeing with auto-complete.
Symptom #3 (of many)
dim bMyBool as Boolean 'becomes dimb (if i wait too long after typing dim)
a short time-out period for auto-complete
Symptom #4 (of many)
Me. 'flashes list of properties/methods for Me, but disappears in 0.25 seconds
This is very annoying and counter productive to me - Microsoft products suck like 80% of the time.
BTW, is the topic i'm asking about called "auto-complete", "context-sensitive help", "type-ahead" ??
Thanks,
Johnny

I believe the word you're looking for is "Intellisense"
|
|
|
|

I'm about to rip Microsoft's balls off and shove them down their throat -- except MS doesn't have a pair!
This next symptom has me thru the roof!
If (expression) Then
(statements)
Else
(statements)
End If 'WTF - it breaks EndIF into two words End and If and i can't even save it as 1 word

That's because in VB syntax the end of an if block is End If not EndIf.

That's because the End keyword works with other stuff, not just If, like End Sub, End Function, End Select, ...

If a single space character is driving you this nuts, you've got other issues to worry about...

I still want to feed MS their own body parts!
I guess I'm gonna reinstall. my latest complaint about my Access 2007, VBA is that when i (mistakenly) issued a search for a word while there were no code windows open, the VBA editor got frozen and was unresponsive to Cancel, any menu commands, and the Hour Glass icon just remained persistent.
So reinstall is what I think i will try next. I don't know what updates hosed over my Access, but now i'm just pissed.
the biggest annoyance/problem is:
defining variables, such as
dim bMyVar as Boolean
but having it appear as
dimbMyVar
dimb MyVar asBo
dim
MyVarasBo

yes, it does, and yet "Endif" (without space) is a reserved keyword and cannot be used as an identifier, e.g. for naming a variable. That is very basic for VB users.

Yeah, I was wrong on the whole "EndIf" "End" dilema. Sorry.
However, my problem was that Intellisense (or auto-complete, context-sensitive help) was all screwy in my VBA code so much so that I couldn't work
1. if i type to slow, the cursor jumps back to the end of the last character, removing spaces and as you can see, trying to define variables would run type and variable name together. :mad:
2. if i try to look up a property for an object, the list would disappear all too quickly. :confused:
Does this call for a re-install of Access 2007?

if it hinders your work continuously, I would certainly give that a try, without hoping too much.
I only ever did one Access+VBA project, more than 10 years ago; it was a simple application, about 3 forms, simple logic; I stumbled on dozens of bugs, each requiring newer versions, fixes, workarounds. I got it to work after lots of trouble, so I try not to do another one any time soon.
Good luck though.

how to add super script and subscript in VB and in SQL table?
|
|
|
|
|
with code.
See how much it sucks to get a vague, generic answer?
That's how it feels to see your vague, generic question.
|
|
|
|
|
If you know the answer just tell me. or else just leave it . I didn't beg u to answer my question. While writing code i had problem so only asked. Is there any rule that we should not ask simple questions?
|
|
|
|
|
He would if your question was answerable. Since you're leaving out critical details about what you are doing, it's impossible to answer your question.
|
|
|
|
|
Well.. funny you should ask, the rules[^], specifically number 2, actually kind of say yes, you should not ask vague, unanswerable questions.
|
|

No VB.Net code editors support super/subscript (or VB for that matter, but who cares about extinct languages).
SQL certainly does not support them either.
Maybe you could be more precise here. Are we talking about rendering to HTML? RTF? a Word Doc?

Hi everyone, I have a matrix and I need to add the money earned this year and past years. However, I must remove the money spent in past years. I must have the separate amount per year and the total of these amounts. This is what gives my matrix:
Year
= Fields!Year.value =formatnumber((sum (Fields!Results.Value)) - (sum (iif (Fields!
Year.value < Parameters!ChoosedYear.Value, fields!Moneyspent.value,
0))), 2) & "$"
However, the subtotal gives me an error. What should I do?
P.S.: I already found that the subtotal gives me an error because it's not in the scope of the rowgroup1, but is there a way to get the scope in the subtotal? or can anybody find another way to do it?

Hello to All,
Is it possible to hide Font Bold Propery from FontDialog.
Thanks
If you can think then I Can.
|
|
|
|
|
You can't
If you just want to offer the different fonts without styling and sizing etc. how about just showing a combo box with the list of installed fonts?
e.g.
Dim installedFonts as New System.Drawing.Text.InstalledFontCollection()
For Each family As System.Drawing.FontFamily In installedFonts.Families
me.comboBox1.Items.Add(family.Name)
Next
