Hi, I'm using Visual Basic with the autodesk aawinplay tool for VB. It
seems to work will most of the time but sometimes I get the error…
Animation Error. You are attempting to use an invalid animation handle. I
never use handles in my code I only pass the filename of the .flcs. What
could be going wrong?
Though you don't think you are using handles, handles are passed all over
the place. They are given a different appearance in VB. When you load up
or open an animation a handle to that animation is generated. All further
references to that animation are via that handle. If that value gets
destroyed, or if you call a function out of the DLL while using a different
or invalid handle, this will generate this message.
I can't be more specific without seeing the actual code you are using.
