How does one get the 'UNIT message' of the, say ONPAINT, function in the other class?
To get a dialog in a CTabCtrl to initialize when selected, unique identifiers (WM_APP + 1)were defined and sent. This works fine as the WindowProc function receives the message and then branches to the appropriate initialization. Would one have to do a user defined message to the WindowProc in the other class, and then issue the function call?
Thanks.

But why you dont use of CListCtrl?

In the existing code,they r using list box. They r passing the listbox variable to some other functions.If i changed listbox to listctrl,i need to change the existing code also. So i want to add gird to list box without doing any changes in the existing code.

i have this code guys:
j = -3;
for (i=0;i<3;i++)
{
switch (j+2)
{
case 3:
case 2: j--;
break;
case 0: j += 2;
break;
default: j=0;
}
if (j>0) break;
j = 3-i;
}
i want to write this without the breaks and goto
how can i do it gurus?

int j = 1; Remove everything else.

I am trying to create 512 CEdit boxes with a "3D" look to them. I know I need to use CreateEx with the style WS_EX_CLIENTEDGE. My Code is below (I have this code in OnInitDialog):
CEdit *EditArray[512];
for(i=0;i<512;i++)
{
EditArray[i] = new CEdit;
EditArray[i]->CreateEx(WS_EX_CLIENTEDGE, _T(controlname), _T(""), WS_CHILD | WS_VISIBLE, CRect(topleft,bottomright), this, i+1500);
}
This code compiles and runs without a hitch...except that the textboxes are never visible. If I switch to a simple CEdit::Create it works and all the textboxes display. Please note that I have code in addition to the above which displays the textboxes in different locations (topleft & bottomright are changed for each textbox). Does anyone have any suggestions as to why I am unable to view these textboxes?

If you want CreateEx() called more than once, you should consider wrapping it with curly braces.

Right...as I said, this isn't my exact code...curly brackets have been added...back to main question...

The controlname is CString.
controlname.Format("EDIT%u", i);
So...
EDIT0
EDIT1
EDIT2
...
EDIT511

If your car doesn't work, do you send another car of the same type to the garage?
I mean, it's hard to help you if you don't provide accurate information and post something else than the code that doesn't work.

Hint: Have a look at what CreateEx() returns and if it happens to be FALSE you might want to check out what GetLastError() returns.... 
You have to use a registered window class and the names you create on the fly are not registered window classes.
Your call should look like this:
CreateEx( WS_EX_CLIENTEDGE, _T("EDIT"), _T("").....

How would I be able to use a registered window class for each of these CEdit boxes? Where/How do I register "EDIT0", "EDIT1", etc...
|
|

You really need a different CLASS for each control?
I'm curious - what are you trying to do?

I'm simply trying to make 512 Edit Controls programatically. In addition to this I would like them to be "3D" which requires the CreateEx. Other than that I'm open to any solution.

Ah...found my problem. If I simply use "EDIT" as the class name it works. I guess for some reason I thought I needed a new class for each Edit Control. Thank you Mark for giving me the right clues!
|
|
|
|

Give them different names... different IDs.... but different classes? 
Glad you got it!
Cheers,

Don't confuse a window class (EDIT) with an MFC class (CEdit).

I thought I told you that, or at least I tried with the code snippet... 
Glad it works now, but a dialog with 512 edit boxes? 
I guess I would close that window and never open it again....

You may have intended to say it, but that does not mean it got read. Go back and re-read your post. Notice anything missing, like:
"...display. Please note that I have code in addition to the above which displays the textboxes in different locations (topleft & bottomright are changed for each textbox). Does anyone have any suggestions as to why I am unable to view these textboxes?"
