.ax is just the extension that Windows XP/Vista/etc. use to indicate
DirectShow filters. If you want to use the .ax extension you can just
rename
your .dll. Windows CE/Mobile DirectShow will accept filters with either
extension and treat them the same.

Hi,
Write another application (exe) which calls the DllRegsiterServer
function
that is exported by the dll.
LoadLibrary()
GetProcAddress(DllRegisterServer)..

Hello Everybody
can anyone help me how can we register the directshow filter(
transform
filter) in Pocket PC device.
In system, we can register it via Regsvr32 i.e.regsvr32 <full path
of
target>
but how can i do the same in device...
or there another way so that we can use directshow filter ( our
own
written
filter) in device.
thanks in advance
looking for your response

Hi
Thank you for your question and answer.
How did you generate a ".ax" extension ? Only by renaming a DLL?
Something else in Settings ?
(I just succcessed to compile (!!) the NullRenderer from Gary Daniel)

Thank you for your help.
I could not compile theCSampleGrabberat all on CE5.0. Have you
working version of this essential Code for me?
Thank you VEEEERRRRRRYYYYYYYYYYY MUCH!!!
Michel
What problem are you having when compiling on CE 5.0? Do you mean Windows
Mobile 5.0, or are you compiling with Windows CE 5.0? They are different,
Windows CE 5.0 is shipped via Platform Builder and used for general
embedded.
I've only tried this with the Windows Mobile 5.0 SDK for visual studio, I
have not tried compiling it for CE 5.0 but it should work the same. I have
compiled it for CE 6.0. If you're compiling it for CE 5.0, you'll need to
generate an SDK with DirectShow when you build your image in
PlatformBuilder.

OK. I found some code of CSampleGrabber. It compiles. I just cannot
register it:

Compiled in Release mode with your precious recommendations
I Got :
DllRegisterServer for CSampleGrabber hr=800401f9
Some Ideas?
