Using C3 out of bds 2006 and Delphi7, I am having difficulty with receiving
intelliable data in the Delphi 7 app. (Sending the other way is
intelliable).
if (outStream.CanWrite)
{
string sendMsg = "Good Day";
Byte[] data = System.Text.Encoding.ASCII.GetBytes(sendMsg);
this.outStream.Write(data, 0, data.Length);
}
From the above, the receive event contains this
procedure TForm1.TcpClient1Receive(Sender: TObject; Buf: PAnsiChar;
var DataLen: Integer);
var
P: PChar;
recvdString: String;
begin
if (Sender is TCustomIpClient) then
begin
P := @Buf;
recvdString := PChar(P);
memRecv.Lines.Add('Recd: ' + recvdString);
end;
....
end;
The following in an onConnect event produces similar problems
var
A: array[0..79] of Char;
P: PChar;
bufsize: Integer;
begin
TCustomIpClient(Sender).ReceiveBuf(A, bufsize, 0);
if not (bufsize = 0) then
begin
P := @A[0];
recvdString := string(P);
end;
.....
end;
I apologize if there is a more suitable newsgroup.
