Can CSocket be used in non-MFC frame programs?

I know that the notification to CSocket object is distributed through MFC's
message map. So, in order to use CSocket to simplify network programming in
non-MFC program is something not so easy to do.
I wonder if we can use CSocket as we use CString in a non-MFC frame
program.

Thanks to anyone who can give me advice.

Hi
I'd created a MFC communication dll which is used in a Delphi application.
I'm connecting MFC program with Delphi program by CAsyncSocket.
This is how DllMain looks

BOOL APIENTRY DllMain( HANDLE hModule, 
                       DWORD ulReasonRorCall, 
                       LPVOID lpReserved )
{
    BOOL fRet;
	switch(ulReasonRorCall) 
	{
		case DLL_PROCESS_ATTACH:
		            fRet = AfxSocketInit();
		break;
        
		case DLL_THREAD_ATTACH:
		case DLL_THREAD_DETACH:
		case DLL_PROCESS_DETACH:
		break;
		default: 
			return FALSE;
	}
    return TRUE;
}

Then you just do what you have to & it will work.
The only wierd thing I got was assertion on init dll which I ignored & everything went good.

You can use CString because it hasn't a base class. On the other hand,
CSocket has a base and it's the CObject. I wouldn't advice you to try use
the CSocket without MFC.

You can use the Windows Sockets API almost as easy. Look at the WIN32s
Samples, at the WSOCK sample- It demonstates this API.

Zhong,

CSocket needs the AFX to work in asynchronous mode. If you are doing non-MFC 

applications we find we get best results programming the Winsock library
directly. In Win32 apps you can use blocking network calls and multiple
threads of execution.

Hope this helps
