To call NewStillcapture() method IStillCapture.h is used. I am calling that method in my solution. But its giving the above mentioned Link error. Please help me to come out of this mess Thanks in advance

Did you add StillCapture.lib in the "Additional Dependencies" option of your project settings ?

for IAMVideoControl interface, did u link to Strmiids.lib ?

[arun_pk]

strmbasd.lib StillCapture.lib baseclasses\STRMBASE.lib THESE are the only dll's which we are linking

[arun_pk]

yeah added. strmbasd.lib StillCapture.lib ..\baseclasses\STRMBASE.lib these are the libraries which we added in additional dependencies

[Cool_Dev]

Try adding Strmiids.lib and Quartz.lib also in additional dependencies. These are the import libraries for most of the codes declared in various headers of DirectShow.

[arun_pk]

where can refer those libraries i mean while adding the lib's through additional dependencies

[Cool_Dev]

If you are using DirectX SDK, then these will be in DXSDK\Lib. If you are using Visual Studio 2005 or later, DirectShow is included in platform sdk and paths would be set in Visual Studio. So simply add the lib names only.

i am using visual studio 2008 so i added directly Strmiids.lib and Quartz.lib still same 7 errors :(

[Cool_Dev]

[Cool_Dev]

are you developing filter? so u are not using directx sdk, instead windows sdk (vista or above) only?

[arun_pk]

filter .... :( we are using only windows sdk

[arun_pk]
