Making Video Capture library using Direct Show for windows mobile

[winceeeee]

Hi all,

I am developing an application in C# to record video. For that i am making a
WINCE Dynamic Link Library in Embedded Visual C++ 4.0 which I can call from
my C# application.

I am developing this application for ARMV4I.

In eVCPP 4.0 following is my directory setting:

C:\Program Files\Windows CE Tools\wce400\STANDARDSDK\Include\ARMV4
C:\Program Files\Windows CE Tools\wce400\STANDARDSDK\mfc\include
C:\Program Files\Windows CE Tools\wce400\STANDARDSDK\atl\include
E:\PROGRAM FILES\WINDOWS CE TOOLS\WCE500\WINDOWS MOBILE 5.0 POCKET PC
SDK\INCLUDE\ARMV4I

Following is my stdafx.h file

#include <windows.h>
#include <winbase.h>
#include <atlbase.h>

#include <streams.h>
#include <dmodshow.h>
#include <dshow.h>
#include <dmoreg.h>
#include <wmcodecids.h>
#include <uuids.h>


When I compiled my dll project I am getting following errors.

Anyone know whats wrong in my project setting?

Thanks
