If I use windowed activation (giving a valid
HWND to the Flash PLayer in the
GetWindow function is enough to trigger this), the player will run the loaded swf file. However, if I use windowless activation, the loaded file does not run, only the very first frame is displayed. This article claims that I'm supposed to call
DoVerb(OLEIVERB_SHOW, NULL, (IOleClientSite *)this, 0, NULL, NULL);
However, this does not have any effect. What am I doing wrong?
Since I made this post, I found out that it returns -2147467259, which is not a known HRESULT, but certainly not 0. What does it mean?
More information: After some more digging I found out that the return value is
I have found the problem. Before this call, I was doing:
hr = _shockwaveFlash->put_WMode(BSTR("opaque"));
BUT I blatantly ignored the HRESULT there. It made the Flash Player confused, because it is not a valid way to insert a
BSTR constant in the code (which is a wide string). Correctly:
hr = _shockwaveFlash->put_WMode(L"opaque");
Now it works as it should. Check you HRESULTs, kids
