String sent with sockets
I get this code from another soft built by VC++ 6.
So then, ive tried to transate it to VC++8.
Server Side:
In the Socket.cpp:
void Socket::OnReceive(int nErrorCode)
{
long dataLength;
Receive(&dataLength, 4);
if (dataLength > 0&& dataLength < 100000) //Just to make sure the client doesn't crash the server)
{
byte* message = new byte[dataLength+1];
int nRec = Receive(message,dataLength);
message[nRec] = '\0';
::SendMessage(hParent,WM_RECEIVE_MESSAGE,(WPARAM)message,(LPARAM)nSocket);
}
Dialog:
char* pMessage = (char*)receiveMessage;
CString message = (CString)pMessage;
//int *pSocket = (int*)nSocket;
//int numSocket = (int)pSocket;
MessageBox(L"Data: "+message);
now my probleme is that i dont get the string sent correctly.
i get some symbol instead.
here is the send code in the client side if you need:
long userl = m_user.GetLength();
UpdateData(TRUE);
SocketA.Send(&userl, 4);
SocketA.Send(&m_user,userl);
Maybe i type casted wrong ?
"m_user" is a edit box in the dialog(CString member)
Thank you from advance

If it really is a UNICODE problem and nothing else, then this will fix it:
LPCSTR pMessage = (LPCSTR)receiveMessage;
CString message = pMessage;
Note that it's LPCSTR (not LPCTSTR) and that pMessage isn't cast to a CString.

You have the old style look because you remove Unicode. To get the "new" look either way, look at your stdafx.h file... you'll see at the bottom, something like this:#ifdef _UNICODE
#if defined _M_IX86
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_IA64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='ia64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_X64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#else
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif
#endif
You'll notice that this is wrapped in an #ifdef _UNICODE. Remove that #ifdef (and the matching #endif) and the new style will appear without Unicode.
Hope that helps.
