Ok, I added the _T() abound the Characters in .ReverseFind( '\\' ) );

But that is not the problem... The problem I am having is that the Amimation
does not run...
I see a stationary hourglass. But it does not move.... If the user refreshes
the window, the stationary hourglass disappears and the ctrl that is about to
get populated with the search results from the background process kindof
becomes blank.. which leads the user to fear that the program has crashed,
which is not the case... it's just that the animation is not working.
Please note that this same code used to work when compiled in the older
versions of VS.

Thanks
Srishti

My guess is its the difference between the V5 and V6 (XP, common control
manifest) implementation of the control. A behavior change is documented
here...

http://msdn.microsoft.com/library/en-us/shellcc/platform/commctls/animation/styles.asp *

....In earlier versions, "By default, the control creates a thread to play
the AVI clip", whereas in the V6 version, "By default, the control plays the
AVI clip without creating a thread". Which I suspect means that, "If ... the
control plays the clip without creating a thread; internally the control
uses a Win32 timer to synchronize playback", and which I think means that
you need to return to the message loop so that WM_TIMER message are
processed. Are you by any chance running a loop that precludes this?

Uhh.... Not sure if I understand that all the way... No It is not in a
loop... if that's what you meant? But there are loops after starting the Play
and before the Stop!

Does thta make any sense?
Thanks a lot

Hi Srishti,
I performed a test on this sample project:
http://www.codejock.com/support/articles/mfc/general/g_3.asp

After I upgraded the project to Visual C++ 8.0, everything still worked
fine. You may download the project for comparing it with yours.

If it does not help, could you reproduce your issue in a test project? If
so, is it possible for you to mail me (changliw_at_microsoft_dot_com) a
sample project for further research?

Best regards,
Charles Wang

I confirm that: I've tried that, too.

However, the aforementioned sample loads the AVI from resource, instead OP's
code loads the AVI from an external file (if my understanding is correct).

I would suggest the OP to check the *return value* of AVI control
CAnimateCtrl::Open method for success.
It may be that the control fails the loading of external AVI file?

And what happens if the OP's AVI file is embedded as a resource, like sample
pointed by Charles?

Giovanni
