Animation of bitmaps

Hi fellows. I've got to do an animation. I have 18 bitmaps and I have to animate them, simply, one after another one. I use a timer that calls InvalidateRect(NULL, FALSE) so that the window gets repainted (I do all the calculations in OnPaint to determine which is the next image of the sequence to be shown).

However, this is causing my window to flicker... How do I do to avoid such annoying problem?

Any help will be really appreciated. Thanks in advance.

Regards,
Fernando.

First, when you call InvalidateRect(), don't pass NULL. Calculate the correct rect of the bitmap and pass that.

Second, when you call InvalidateRect(), don't pass FALSE. You don't need to erase the background, this only causes the region to be painted twice.

Third, Use double buffering. Do all your drawing off screen then draw everything back to the screen in one go.

Thanks, I thought so at first, however, MFC for CE does not support CAnimationCtrl... Indeed, I solved the problem by creating a CWnd-derived window, and I placed the animation in there. Since it's a window in its own, it does not flicker at all.

Fernando.

I have added the options Enable Profiling and Generate Mapfile to the link options of the resp projects I would like to profile and rebuilt the proj. But still I do not have the profile menu item in my build menu activated. cud someone point me out where I am going wrong?
Also what is the procedure to enable profiling in VS9.0, cud someone provide me the step-wise procedure?

Thanks and in anticipation of an early reply.

that is not legal C++.

the easiest way to do this is with a string class of some kind:

CString Value = variable;

std::string Value = variable;

or, if you have to use a char array:

int iLen = strlen(variable);
char Value = new char [ iLen + 1 ];
strcpy(Value, variable);
Value[iLen] = 0;

...

delete [] Value;

O.K ... Thanx for the response ... But why do I always get this error, I mean I am using:

<code>
using namespace std;

error C2065: 'CString' : undeclared identifier
</code>

CString is not the STL std::string class. it comes from MFC.
