Assuming this is a continuation of your previous problem, I already suggested this[^], and similarly tried to explain, here[^], about the correct use of casts in C. Randomly changing parameters or removing them altogether is no substitute for making full use of both documentation and debug information.

I did that and I still encountred the problem breakpoint followed by access violation
bottom line till me if I right
CFileDialog.mydialog(TRUE);
mydialog.DoModal(TRUE);
Should work as it would take default paramters correct ?

Not necessarily, as we do not know what else your code is doing. As I said before, read the documentation[^] and carefully check against your code. Also ensure that your project has been completely rebuilt to ensure no undiagnosed compiler errors remain.

I'll re-read the doc
but
1) I got s clean build
2) this is the first thing in CWinApp::InitInstance
thank you

There must be something wrong with your system that we are not aware of. Does this application run correctly if you do not use the CFileDialog?

Yes it does
I am begining to think it must be something like file permissions
I live next to someone who worked for MicroSoft
He had a look at it once I'll ask him again

That is most unlikely unless you have a Microsoft library that is corrupt or somehow unreadable.
I just reread some of your earlier posts and noticed :ForNow wrote: doing a Call Stack at this point seems that mscowrks.dll is executing
This, according to http://www.ehow.com/facts_7827759_mscorwksdll.html[^] is a .NET library, so I would be interested to know how that is getting connected to your app.

The first thing? Maybe you are not giving the framework enough time to get everything ready. Perhaps putting the code someplace else (e.g., in response to a button click) would work better.

I created an empty dialog-based app with the following change:
BOOL CDCDlg::OnInitDialog()
{
CDialog::OnInitDialog();
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
CFileDialog dlg(TRUE);
dlg.DoModal();
return TRUE;
}
It worked fine. Can you try something similar?

There's a known problem with CFileDialog crashing although I can't remember the exact situations. Something to do with WINVER, I think. Anyway, you can test if this is what your problem is by creating the dialog on the stack and seeing if that stops the crash.
e.g.
CFileDialog* pFD = new CFileDialog(...);
pFD->DoModal();
.
.
delete pFD;

It was actually related to trying to use a CFileDialog object, which references m_pMainWnd, in a dialog-based app after the main dialog had been dismissed.

OK I did embark into world of DirectShow and ditched VFW.
All the code samples here is way over my head for now.
I got as far as “using SDK to build basic DirectShow”. It is in one of many SDK 's “help doc” MS puts out here and there about DirectShow. I am suppose to build basic DirectShow application and use it as accessible debug library. I must be dense, but I cannot figure how to do it.
I do not need full blown sample code, there are plenty of them here, but gentle nudge into right direction in building from SDK sample would be appreciated.
Thanks for your time.

Create the sample project in Visual Studio and press the "Build solution" button. Without more information on what problems you are having it's difficult to suggest anything more.

Two reasons for this update.
Soren, I did not delete my last post, I guess gremlins at work.
Second, I am making progress using DirectShow, however, I just got past enumerating video devices and still struggling with DirectShow overall concept.
I just love MS inventing all these therms with very terse explanations – graph, filter , bag, moniker etc.
Old fashioned flow chart would IMHO work much better than MS one pages samples which are not tied together.
The most confusing are the VMR options – windowless or with window?
And when you do search all you get is reference to Window7, back paddling to XP as I do is inevitable.
But eventually I'll get
Thanks for your help.

Hi,
I have Dialog in a Property Sheet. I have a picture control on that dialog box. I have a Bitmap which I want to use on that Picture control. I am using the below code for this part:
if(::IsWindow(m_CapScreen.m_hWnd ))
{
tempbmp.LoadBitmapW(IDB_BMP_VIDEO_SCREEN_BOX);
tempbmp.GetBitmap (&bm);
m_CapScreen.MoveWindow( rt.left + 51, rt.top + 25, m.bmWidth, bm.bmHeight, 1 );
tempbmp.DeleteObject();
}
where m_CapScreen in a variable declared for picture control.
When I change the position of the picture control, the Bitmap Image doesn't move with the picture control. It will remain at a fixed position.
The "Type" property of Picture control is set to "Frame".
Any help will be appreciated.
Regards,
Mbatra

I don't see the connection between the bitmap and the picture control in the above code. Does this paint the bitmap in the correct place to start with?

Hi,
"m_CapScreen" is defined as,
DDX_Control(pDX, IDC_CAPSCREEN, m_CapScreen);
which is a picture control, it type property has beent set to "Frame". So it will act as a frame to the bitmap positioned on the dialog.
Or else plz give me any suggestion if we can stretch a bitmap.
Whenever I change the resolution of the PC, I want to change the size of the bitmap accordingly. I can change the position and size of the controls, but prob is with the Bitmaps, BMP size I can't change. So I was looking out any way for this.
Regards,
Mbatra

What MFC class is it and how are you adding the bitmap to it?

I have 3 objects on the screen, I want to rotate onll 2 objects the axis and X,Y,Z. Another line is there which I want not to rotate. But with this code below all are moving. Check below my DrawScene function.
[code]
void CopenGLCoordView::DrawScene(CDC *pDC)
{
wglMakeCurrent(pDC->m_hDC, m_hrc);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glEnable(GL_DEPTH_TEST);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
if (wd <= ht)
glOrtho(left, right, top*ht/wd, bottom*ht/wd, znear, zfar);
else
glOrtho(left*wd/ht, right*wd/ht, top, bottom, znear, zfar);
glPushMatrix();
glRotatef(rot[0], 1.0f, 0.0f, 0.0f);
glRotatef(rot[1], 0.0f, 1.0f, 0.0f);
glRotatef(rot[2], 0.0f, 0.0f, 1.0f);
glCallList(axes);
glPrintX("X");
glPrintY("Y");
glPrintZ("Z");
glPopMatrix();
drawLine(); //This is also moving...i want this to not to move...
glFlush();
SwapBuffers(pDC->m_hDC);
wglMakeCurrent(NULL, NULL);
} 
[/code]
