Using a flash ActiveX control in Win32

[Pablo Hernandez Valdes]

I'm having problems when I try to use a flash ActiveX control in a Win32 application (non-MFC) I don't know why this exception is thrown: First-chance exception at 0x10058561 in MM.exe: 0xC0000005: Access violation reading location 0x00000000. Unhandled exception at 0x10058561 in MM.exe: 0xC0000005: Access violation reading location 0x00000000.:confused: Is something wrong with the code? #import "c:\winxp\system32\macromed\flash\flash.ocx" named_guids ........................... CoInitialize(0); IShockwaveFlash* pFlash; HRESULT hr=CoCreateInstance(CLSID_ShockwaveFlash,NULL,CLSCTX_INPROC_SERVER,IID_IShockwaveFlash,(void**)&pFlash); pFlash->LoadMovie(0,L"test.swf"); Thanks:) Pablo Hernandez Valdes

Hi Pablo, Sounds like the CoCreateInstance didn't work. Access violation was probably due to pFlash being NULL (in debug at least). This is what I used to verify the code worked:

ShockwaveFlashObjects::IShockwaveFlashPtr pFlash = NULL;
try
{
	HRESULT hr = pFlash.CreateInstance(\_\_uuidof(ShockwaveFlashObjects::ShockwaveFlash));
	if (SUCCEEDED(hr) && pFlash != NULL)
	{
		pFlash->LoadMovie(0,L"C:\\\\Inetpub\\\\wwwroot\\\\pds\\\\try1.swf");
	}
}
catch(\_com\_error& e)
{
	TRACE1("EXCEPTION: %s", e.Description());
}

NOTE: I've used the smart pointer implementation Hope this helps, Andy
