I'm not sure what type of information you need to help me with this, but here is a list of the error messages i get when i try to compile. Any suggestions on how i should go about to locate the error? Have been trying for a couple of hours now...

The errors are caused because somewhere in your code you are duplicating symbols that are already defined in DShowClass (or rather, the file that this class is declared in), which I suppose is of your own creation.

From the information you provided, I can't exactly tell what you are doing wrong, but it's probably one of the following:

- You are putting variabele definitions in your .h file. You should always put variables in a .cpp file and only add an "extern" declaration to the .h file (if necessary).

- You are #including a .cpp file. You should only #include .h files.

I have a vuage recollection of a define you should put in before including the DX stuff (DirectShow has always been a shoddy bolt-on to DX).

Something like DX_GUID I think it was.

Searching on the MS developer support might turn something up.

CrystalSquid I think you're talking about the
#define INITGUID

But if you link your project with dxguid.lib then you don't need the #define

hth

Thats the thingy!

Thinking about it - don't think it will help, sorry!

One more thought just popped into my head - you may be trying to link a library twice.

You should ba able to set the linker to 'verbose' and it should tell you all the libs it links with. Check if DShow.lib is occuring twice :)

Thank you for your help! I succceded to get it working. What i did was to remove the #define INITGUID and instead include the dxguid.lib and it worked! Would never have tried this without your help guys! Thanks alot! :D
