I using FlexGrid component .In that i fixed the column width and row minimum height. When the cell contains more text it wraps but not visible. i mean its not auto fit rows.
I want when the cell has more text depends upon the text i have to resize the row height not a column width.
Thanks & Regards

I dont think there is any "auto fit" function available - maybe you could try this...
Set the "User Resize" property of the FlexGrid to "Rows" (or "Both"). This will only work if you have at least one fixed column (and/or row). If you place your mouse pointer at the junction of two rows, you should now see a re-size pointer which you can then use to drag and set the row height as you want.
Hope this helps.

When I'm using an API spy over the "webpage" part of the web browser, Firefox to be exact, it never reads an textbox's handle or any control. Just "MozillaWindowClass". So my question is how do I find its handle? or is it even possible?
P.S. Its the same thing with IE and the new AIM6.

I'm not sure if this is right board.... Does anyone know if there are problems using msscript.ocx in multithreaded environment? specificaly I'm using it from C++ COM object that is called from IIS. Each clients session has an object for processing some vbscripts. What I'm seeing is that if one client destroys the msscript object/ or even just calls "reset" on it another object of it on another thread dies as well. - cut right in a middle of a vb call
Please help!

hi
I'm programming a Yahoo! Messenger mini-client.
I'm using BrickSoftIM FastIM COM class...
Here's the code:
Dim WithEvents myYAHOO As FastIM_YAHOO<br />
Public Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
myYAHOO = New FastIM_YAHOO<br />
End Sub
with only one event-handler:
Sub myYAHOO_OnLogin() Handles myYAHOO.OnLogin<br />
log.Text = log.Text & "Logged IN!!!" & vbCrLf<br />
End Sub
like this, It works perfectly, BUT when I add anoder event-handler:
Private Sub myYAHOO_OnError(ByVal ErrorCode As Integer) Handles myYAHOO.OnError<br />
log.Text = log.Text & "Error Code:" & CStr(ErrorCode) & vbCrLf<br />
End Sub
I get this error: "Exception from HRESULT: 0x80040202" 
I saw many help-requests on the net about more than just one event-handler when using COM classes but haven't found a solution
Help much appreciated tnx !!!
EDIT: This problem is only in VB.Net, The same code in VB6 works perfect...

Hi,
I am not sure about the multiple event problem in general, but in your case, I strongly recommend not to try and handle errors "manually". Vb.net has the try and catch statements if you need to handle errors:
<br />
Private Sub something()<br />
Try<br />
'your code here<br />
Catch ex as Exception<br />
'your response to the expected error here, for example:<br />
MsgBox(ex.Message)<br />
End Try<br />
End Sub<br />
The Catch statement can monitor for specific errors, or errors of a certain type (for example sql errors). If you don't want to write your error handling code for each Sub and Function separately, just write your own error handling function or sub somewhere, for example:
<br />
Public Function ErrorHandler(ByVal err As Exception)<br />
MsgBox(err.Message)<br />
End Function<br />
Good luck,
Johan
My advice is free, and you may get what you paid for.

Yeah I know about try/catch, and I did implement it along with anoder code hoping that the HRESULT would be translated into a .Net exeption... but yet again the msgbox contains only "Exception from HRESULT: 0x80040202"
I saw many many translations of this HRESULT on net, but still no solution...

I'm looking for a good manual about writing code for developing controls, as well for the code as for the designer part. I need good and extensive information about the several classes often used in controls: parentcontrols, containercontrols, controldesigner, etc... Anyone has a interesting link for me?

I am trying to use the following code to make sure all codes are closed when clicking the x in the top right hand corner.
---
Private Sub frmTestTop_FormClosing(ByVal sender As Object, ByVal e As system.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
me.close
End Sub
---
It is however coming up with an dll stock overflow error, what am i doing wrong?
Is there an easier way to do this???
Cheers

if u wanna close alll your forms, you can just put a close button on your form and code application.exit() or End in its clickin event ..
thats it....
|
|
|
|
|
Its the close button in the control box, which when you click it just closes the current form, not any that may be hidden.
Any ideas?
Its in vb.net 2005 btw

Application.Exit() ?

I hadn't ever heard of that one either, but it really exists...

The reason you are getting a Stack Overflow Error is because in your code, FormClosing allows you to perform last minute steps before the app shuts down. So when your app tries to close, you call Me.Close() which loops back and calls the same function continually.
I hope that makes since.

Yeah i get it. The reason i am trying to use it, is because the first form, i want to show another one and CLOSE the original form, however, when i close the first form, the whole program closes, so i had to hide it to get around this. Is there any way to get around this??? Sorry to bother you all, I'm just really stuck and its annoying!!

|

Well you can just hide the first form (Me.Hide()), and then when you want to close all the forms, use Application.Exit().

well i think if first form is hidden by using me.hide(), then u wont be able to close it through form2(or your most active form)using that cross button in controll box. and even if you could then why to increase complexity.
jst hide yr form one and close yr succesive forms by me.close
and appliction.exit on the last form will be the easiest way...
try it out...
