It's hard to identify the problem with this. also this stack trace is not complete. I don't know how this had happened. There should be something wrong with your debugger configuration otherwise it would show the right location.
Are you debugging the application or activeX. You said you already saw the call stack from dialog. Trace it down, and ensure that there's nothing fishy until you make a call to ActiveX. and then debug ActiveX

This is the full call stack under the thread that showed un-hnadled exception.
I'm debugging the application.Dont know its driving us crazy.
Thank u

My guess is that the exception you get is stack-overflow because some place in your code there is an indirect recursive call.
Launch your application in a debugger and wait for the problem to happen, then you should be able diagnose what code is causing the problem.

I think you must interpret the mouse handling yourself. Googled and found this![^]

You didn't say how you're writing your application but if you're using OpenCV's builtin GUI from HighGUI, Sareth is correct in how to handle it. Be advised though that the GUI interface that HighGUI supports is quite limited. To have any "reasonable" application other than small test cases, you probably want to explore other alternatives.
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Hello, This is probably a very silly question, but it's got me beaten !! I am running MSVC++ Ver 6.0 and want to remove a class from my libary. I deleted the CPP and H files from the folder (and they subsequently disappeared from the Class View) but on rebuild I get error C1083 (can't find source file !!). The dsp file references the class sources files that have been romoved, but I'm not allowed to edit this file. How do I fix this so that the compiler ignores the removed class ? Many thanks !

I think u forget to remove from dsp.
Remove those files from the tree view shown on VC6.0 IDE.

Why are you not allowed to edit this file. You don't need to edit it manually, you only have to open it with visual studio and your full project will be loaded. Then in the workspace tree you simply have to delete the files, they will be removed from the build.

Adam/Cedric, Thank you for your advice ! All fixed now - put it down to ignorance !!

Hi,
I have developed a SDI application and split it into two parts. One part is simple view and another part is form view, in which i have select a dialog as child.
My problem is, I can't change the background of dialog and some 'static text' controls color.
I have used
SetDialogBkColor(RGB(255, 0, 0), RGB(0, 255, 0));
in app class. But its not working.
Pls hlp.
Thanks in advanced

To change the color of a static control do that in WM_CTLCOLOR [^]message

Hi,
Not only controls color, but also want to change the background color

Create a solid brush in FormView's OnInitialUpdate m_wndbkBrush.CreateSolidBrush(RGB(0,255,0)); , and use this in OnEraseBkgnd overload of FormView.
void CxxxFormView::OnEraseBkgnd(CDC* pDC)
{
CFormView::OnEraseBkgnd(pDC);
CRect rect;
GetClientRect(rect);
pDC->FillRect(&rect, &m_wndbkBrush);
return TRUE;
}

Whenever i scroll down, the other portion does not changes. How can i do that?
I have used
void Cxxx::OnDraw(CDC* pDC)
{
CFormView::OnEraseBkgnd(pDC);
CRect rect;
GetClientRect(rect);
pDC->FillRect(&rect, &m_wndbkBrush);
return;
}

Madhu already mentioned that you must do this in OnEraseBkgnd instaed of OnDraw()

You do not call this within OnDraw().

I have created a new class for form view. There is no msg handler for OnEraseBkgnd

OnEraseBkgnd() is the message handler for WM_ERASEBKGND.

Yes, but it is not displayed

As Madhu mentioned, WM_CTLCOLOR is not only for controls, but also for the dialog.
When the wParam is CTLCOLOR_DLG, you can return a brush for dialog box color.
Please read the documentation. It says it all.

i created a project which based win32, and i'll plan to create a mfc-dll for calling in win32, could this idea be implemented?
can you give me some similar code or related articles, thank you very much!

I guess you can call an MFC DLL from a Win32 application.
You should actually try it.
