Resource Dll

I have a resource dll of bmps that I am using to hold the frames of an animation sequence.  When the dll is first loaded the animation plays slowly on the first pass.  After that the animation plays much quicker...
Is there a way to somehow preload the resource to speed the initial pass through?

Yes and you already have the answer your hands....

Make a dummy pass of LoadBitmaps and retain the handles, say in an array)

Re-use these handles each time you play the animation (rather than doing LoadBitmap each time you play a frame, which of course is the cause of your variable speed).

Another solution is to call a (dummy) function in the DLL or access a dummy resource, before playing the animation.  This is not as good.  If the DLL is large, it will tend to get swapped out, again cause variable speed.

Finally one suggestion I think you  should consider is to use an AVI and the animation control (CAnimateCtrl in MFC, but you can also use these in non-MFC programs).  This seems to rarely suffer from this kind of problem
