I have made a dialog based MFC app but found a big problem. If someone is entering values into the edit boxes and then hits enter it closes the program. If you hit enter at all while the program is running and in focus it will end the program. How can I fix this?
Thanks

You can override OnOK() (and possibly OnCancel()) and in your overridden method,
do nothing.

Hi I cannot find those functions anywhere. I have this
CDLIADlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
return FALSE;
Brings up the main dialog, but I can't find the OnOk or OnCancel in the main dialog
|

They are virtual functions declared in the CDialog class. You can
add them through the class properties window or add them by hand
virtual void OnOK();
virtual void OnCancel();
...
void CDLIADlg::OnOK()
{
}
void CDLIADlg::OnCancel()
{
}Mark

Since noone else has replied...
Your code as shown compiles for me (if I add the missing semicolon
and comment out the "[..]") with no errors/warnings.

Running or compiling?

both since I can't compile I can't run

Hmm since I copied the code and compiled it, I can only assume your'e not

my last post has the source code which still don't compile with me

Just a guess, but are you sure that when you compile your test program that the code
<br />
class __declspec(dllexport) CRC32
becomes
<br />
class __declspec(import) CRC32

I guess it does I just replaced the EXPORTS macro Visual Studio made for my code to be explicit on the forum.

Hey there, I was wondering if someone would be willing to show me how to capture a frame from a webcam and turn it into a texture in OpenGL.. I'd like to do this realtime so the webcam is displaying in my OpenGL project. If anyone has some tips that would be great.

This really is two completely different parts to your question...
1/ grabbing a picture from a webcam,
and,
2/ Now I have a bitmap, how do I turn that into a texture and use it in OpenGL.
You'll have luck researching each of these parts, but I doubt anyone will give you the whole thing on a platter.
My guess is that the camera will provide a TWAIN interface for grabbings pics, but I don;t have any direct experience?

I have created a window and done some drawing in the WM_PAINT message (drawing a border at the window's edge). However, when I resize the window, the window isnt updated from the WM_SIZE message. Is this normal and I have to explicitly have to tell the app to redraw the window when it is sized, or is there a window style or something that I have to set for the window to be updated when it is sized?
If I resize the window, minimize it then restore it, then the window has been repainted with the border at its edge, so I know it is something to do with the WM_SIZE message.
Thanks for your help,

Can you show the code you use in response to WM_PAINT?

You could try getting your resize notification from the WM_WINDOWPOSCHANGED message instead.

What are you doing in response to the WM_SIZE message?

Make sure that your OnSize handler is calling the default implementation also.
ie
void CMyWnd::OnSize (....)
{
CWnd::OnSize (....); (or CDialog:: etc - whatever the parent class is
}
