Why I can't create socket ?

I am using xtp pro 11, VC6

I want to create a SOCKET on the MDI window ,when the program running ,it reported socket create error !!

 

In my project, I create a MDI window which is inherited from CXTPMDIFrameWnd, but ,when I wanted created a socket on the child window , although the building is passed , running error displayed !! It was: Can't create socket successfully!The code followed here: 

 

CAsyncSocket*pSocket=new CAsyncSocket;
int nPort=27;
if (pSocket->Create(nPort,SOCK_DGRAM))
{
 AfxMessageBox("passed");
}else
{
AfxMessageBox("SOCKET_ERROR");
}

 

Why I can't create socket ?

 

Created socket in the child window ,the error displayed as the same.

 

If anyone has the solution ,please send email to me:

 

thanks

I forgot add the support of winsock!

Manual call : AfxSocketInit

 

It was done!

 

The toolkit is so good that I can't mean that I should do some basic working.

 

OK, keep touching with me : zlipper@gmail.com
