Class not registered error
-
Thanks, I have called the
HRESULT hr = CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
at the class construction and
CoUninitialize();
at the destruction. Any other filter is successfully
CoCreateInstanceexcept my filter.sdancer75
Get the error returned in hr and use the Error Lookup tool check what the error is.

Hi, As you can see in question at the very begging, the error code is
0x80040154which means "class is not registered" This is strange since the class is indeed registered at sysWOW3264 (a mirror registry for 32-bit windows apps running on 64bit windows) since my source filter is 32-bit. Under ms filter graph, I can find and use successfully the filter, but the problem still exists under my MFC project. PS:In my stdafx.h I declare my filter as follows#include "INITGUID.H"
//{8576CEC8-964D-4B51-AC45-2B24DE748E23} My Async Source (File)
DEFINE_GUID(CLSID_PIAsyncFile,
0x8576CEC8, 0x964D, 0x4B51, 0xAC, 0x45, 0x2B, 0x24, 0xDE, 074, 0x8E, 0x23);Thanx

Sorry, I didn't notice the error code you posted in your question. I'm assuming that the MFC project is built as a 32-bit application. One more thing you can try - There are both 32-bit and 64-bit versions of regsvr32.exe available in %SystemRoot%\Windows\System32 and %Systemroot%\Windows\SysWOW64. Try registering the component with either of the 2 and check if the MFC application is able to find it.

Thanks, Yes I know and I already tried both versions of regsvr32 (32 & 64 Bit) but still does not work. Regards,

All I can think of is that the COM component uses some dependency files like DLLs that GraphEdit is able to find but the MFC application is not. Does the COM component reside is some folder along with other dependency files. If so, you can either try to copy the EXE to that folder or change the working directory using the
SetCurrentDirectoryAPI.«_Superman_» _I love work. It gives me something to do between weekends.

I am not sure about that.... The filter resides is a local folder and not in windows subfolder and is a "debug build". I will try to move the filter inside the C:\windows\SysWOW64 and register again.

Nope !! It drives me crazy. Check an image of the filter registration at the link http://postimg.org/image/ulitc333r/[^] I am attaching you also the source code of the "testfilter code" as well as the filter itself http://rapidshare.com/files/1664813497/TestWin32.zip http://rapidshare.com/files/1868088316/piasyncd.zip[^]
