MCI

[Gian]

How can i use the MCI device in a MFC application? Is possible to put a video on a dialog with it?

I have never used it personally, but it seems MCIWndXXX API could do that. You may check MPlay SDK sample as well. Tomasz Sowinski -- http://www.shooltz.com

I've resolved using DirectShow (perform much things and formats than MCI) but i've a problem passing the CString filename, the function receive a LPCWSTR parameter but i can't find a way to convert it. I've read there's a macro T2W that can do that but the compiler tell me undeclared identifier.. there's some kind of include or it's a way better to convert it?

The T2W macro is in ATLCONV.H, however, you might find it almost as easy to use the AllocSysString function that's part of CString. This will return a BSTR, which in your context could be treated as a LPCWSTR without a cast. However, you must free it after the call has returned; e.g. CString myFileName; .... BSTR tmp = myFileName.AllocSysString(); somefunction( tmp ); ::SysFreeString( tmp ); The T2W and it's friends would require something like; { USES_CONVERSION; somefunction( T2W( myFileName ) ); } Steve S [This signature space available for rent]
