Thread: Socket Programming??

Hi folks,
I'm triying to send message form the client to the server in BCB 6.0 but when I send the message I got immediately "Error receiving" I couldn't find where is the wrong..
Any answer will appreciate..

My code look like this
--- client ---

Code:

    bool __fastcall SendBuffer(TCustomWinSocket *Socket, void *Buffer, int 
Length) 
    { 
        int Sent = 0; 
        int Total_Sent = 0; 
        BYTE *Buf = (LPBYTE)Buffer; 

        while( Total_Sent < Length ) 
        { 
            Sent = Socket->SendBuf(&Buf[Total_Sent], Length - Total_Sent); 
            if( Sent <= 0 ) 
            { 
                if( WSAGetLastError() == WSAEWOULDBLOCK ) 
                    continue; 
                return false; 
            } 
            Total_Sent += Sent; 
        } 
        return true; 
    } 

    //... 

    AnsiString text = Edit1->Text; 
    int length = text.Length(); 

    bool ok = SendBuffer(Form1->ClientSocket1->Socket, &length, 
sizeof(int)); 
    if( ok ) 
        ok = SendBuffer(Form1->ClientSocket1->Socket, text.c_str(), length); 
    if( !ok ) 
        ShowMessage("Error"); 


    --- server --- 

    bool __fastcall ReadBuffer(TCustomWinSocket *Socket, void *Buffer, int 
Length) 
    { 
        int Read = 0; 
        int Total_Read = 0; 
        BYTE *Buf = (LPBYTE)Buffer; 

        while( Total_Read < Length ) 
        { 
            Read = Socket->ReceiveBuf(&Buf[Total_Read], Length - 
Total_Read); 
            if( Read <= 0 ) 
            { 
                if( WSAGetLastError() == WSAEWOULDBLOCK ) 
                    continue; 
                return false; 
            } 
            Total_Read += Read; 
        } 
        return true; 
    } 

    //... 

    AnsiString buffer; 
    int length = 0; 

    bool ok = ReadBuffer(Socket, &length, sizeof(int)); 
    if( ok ) 
    { 
        buffer.SetLength(length); 
        ok = ReadBuffer(Socket, buffer.c_str(), length); 
    } 
    if( !ok ) 
        ShowMessage("Error receiving");

Thanks in Advance

I might look at the code after you put it in code tags.
[ code ] ... [/ code ] (without the spaces).

if( WSAGetLastError() == WSAEWOULDBLOCK )
continue;
return false;
Instead of just returning false, why not print out the value returned by WSAGetLastError(), so you have more information to hand

> ok = ReadBuffer(Socket, buffer.c_str(), length)
As far as I know, these c_str() things are supposed to be constant, so its not correct to go writing into them.
