error code, returned from LoadLibrary() , is 7e

Question

Hi,
   I developmented a DShow filter on smartphone and wanted to load it in my 
application. But it returned NULL when call LoadLibrary(_T("MyFilter.ax")). 
The error code is 7e. And I tried to use Regsvrce.exe to register 
MyFilter.ax, the error code returned is also 7e. However I explicitly put 
"MyFilter.ax" in "\Windows". 
  I tried to load another module, LoadLibrary(_T("aygshell.dll")) for 
example, it succeded. It seemed that the problem existed in "MyFilter.ax". 
How can I do to resolve this? 
   I am very appreciated of any ideals!

Answer 1

0x7e says that the module was not found.

Use DEPENDS and check what it says when it loads this module. Maybe there is another DLL missing.

Answer 2

Thanks,

    I have resolved the problem. The problem is the same as what you said. A dependent DLL is missing.

   However I come into a new problem. On smartphone my application calls RenderFile(_T("MyMusic.mp3"), NULL), but it returns 0x80040218. The smartphone supports .mp3 file. Why don't the Filter graph  connect relevant filters?

I have the same problem... Please help!

.mp3 file can be played by WMP, but can't by DS with error 0x80040218. .wav-, amr-files plays both by WMP and DS without problems...

Any ideas?
