This article shows how to use DCOM on Windows CE 5.0. We will add full DCOM rich error information, and implement a DCOM interface between a Windows XP .NET 2.0 client and Windows CE DCOM server. With this code, it is possible to code .NET remoting alike functionality through DCOM interop.

// We can not use DllMain() because this is already used by the Proxy/Stub generated code
// DllMain is normally called by _DllMainCRTStartup(), the default DLL entry point
// See also "C:\WINCE500\PRIVATE\WINCEOS\COREOS\CORE\CORELIBC\CRTW32\STARTUP\pegdmain.c"
// Therefore we replace the default entry point by our own version
// Make sure you specify this in the project file (/ENTRY:)

#include <windows.h>
#include "channelhook.h"

extern "C" BOOL WINAPI _DllMainCRTStartup(HANDLE hDllHandle, DWORD dwReason, LPVOID lpreserved);

BOOL WINAPI _NewDllMainCRTStartup(HANDLE hDllHandle, DWORD dwReason, LPVOID lpreserved)
{
	BOOL bRet;
	if (dwReason == DLL_PROCESS_ATTACH)
	{
		// Call original DLL entry point first
		bRet = _DllMainCRTStartup(hDllHandle, dwReason, lpreserved);

		// And then install immediately Rich Error Hook
		StartChannelHook();
	}

	if (dwReason == DLL_PROCESS_DETACH)
	{
		// Remove Rich Error Hook
		StopChannelHook();

		// Call original DLL (entry)exit point
		bRet = _DllMainCRTStartup(hDllHandle, dwReason, lpreserved);
	}

	return bRet;
}
