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.
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.

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]

You need to implement the various drawing messages as described here[^].

There is a link to some examples at the bottom of that page. One of those examples, http://msdn.microsoft.com/en-us/library/windows/desktop/aa390421(v=vs.85).aspx, shows how to call a provider method.

Thanks for your suggestion, I tried this and its successful.
I did EnableDHCP and few others but on enable static it's not working.
on enable static IP address is to be there in an array(SafeArray).
Do you have any Idea?
Thanks!

Thanks for your reply. and however, LinearGradientBrush only draw gradient area on straight way. PathGradientBrush might be helpness, but Im not sure how to do with it.

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.

Please do not do this, we cannot go through something like the above trying to figure out what is happening. Use your debugger to narrow down the problem area and post some more specific detail.

Hi guys please I need your help to do a little code at the green comment line in order to do this:
when I try to add new element to an array
4 56 7 10
like 100 at 1 index position
will do this
4 100 7 10 56
it should be like this :
4 100 56 7 10
so the problem is i have to use swap making swap variable take value and them move the rest on order to make like this
4 100 56 7 10
#include<iostream >
using namespace std;
void printarray(int [], int,int );
void gradefull( int [],int ,int&);
void add(int [],int ,int) ;
void main(){
int * gradeArray;
int g;
int elmentnumber=0;
cout<<endl;
cout << "\tEnter the number of elemetn for the array: " ;
cin>>g;
gradeArray=new int[g];
gradefull(gradeArray,g,elmentnumber);
cout << endl ;
printarray(gradeArray,g,elmentnumber);
cout << endl<< endl ;
cout<<"Adding New Element:"<<endl<<endl;
add( gradeArray , elmentnumber,g);
cout << endl<< endl ;
system("pause");
}
void gradefull( int gradeArray[],int g,int & elmentnumber ){
cout<<endl;
for ( int i=0;i<g; i++ ){
int input;
cout << "please insert the element #<"<< i<<">: ";
cin>>input;
gradeArray[i]=input;
elmentnumber++;
}
}
void printarray(int gradeArray[], int g,int elmentnumber){
for ( int i=0;i<g; i++ ){
cout<<"\t"<<gradeArray[i] <<" ";
}
cout<<endl;
cout<<endl <<"\tYou entred <"<<elmentnumber << "> elments";
}
void add(int gradeArray [],int elmentnumber,int g ){
int temp;
elmentnumber++;
int newinput;
int indix;
cout<<endl;
cout<<" Please Enter the postion indix for the new element: ";
cin>>indix;
while((indix>elmentnumber)||(indix==elmentnumber)){
cout<<" Please Enter the postion indix for the new element: ";
cin>>indix;
}
for ( int i=0;i<elmentnumber; i++ ){
if ( i==indix){
temp=gradeArray[i];
cout<<endl<<"\tEnter the new element number: ";
cin>>newinput;
gradeArray[i]=newinput;
}
} cout<<endl;
cout<<" The new Array after Adding the New element: "<<endl<<endl;
if (indix<g){
gradeArray[elmentnumber-1]=temp ;
}
for ( int i=0;i<elmentnumber; i++ ){
cout<<"\t"<<gradeArray[i] <<" ";
}
}
