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.

DirectShow is "no show so far" - need basic help

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.
Cheers Vaclav

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.

I can understand your frustration Vaclav. At first it can seem daunting, but it really is mostly a matter of navigating through a bunch of COM interfaces. Once you get past that, it is not that bad.

Assuming you have read or at least skimmed through the DirectShow Reference[^], I would advice you to get your feet wet using this page: http://msdn.microsoft.com/en-us/library/windows/desktop/dd377566(v=vs.85).aspx[^]
And move on to this page: http://www.geekpage.jp/en/programming/directshow[^] - go to the "Video Capture" section.

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

How to adjust Bitmap onto a picture control in mfc.?

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.

Mbatra

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);
} Smile | :)

At a guess you could use either brush type to flood fill a circle, then overpaint an inner circle in the background colour. That would give you the basic ring shape. You need to do some experimentation to figure out the optimum methods.
