Title: about the sendstream of TNMUDP component
Question: I want to send a bitmap from one PC to another PC in the same workgroup.
procedure TForm1.CUDPDataReceived(Sender: TComponent; NumberBytes: Integer;
FromIP: String; Port: Integer);
var
Rcode : char;
begin
sendstream := Tmemorystream.Create;
cudp.ReadBuffer(RCode,NumberBytes);
if RCode = 'k' then
begin
sendstream.LoadFromFile('c:\mybmp.bmp);
try
CUDP.RemoteHost := FromIP;
CUDP.SendStream(sendstream);
finally
sendstream.Free;
end;
end;
end;
when the project run to CUDP.SendStream(sendstream),it raise the exception,and i change the send-file,sendstream.loadfromfile('c:\my.txt') instead of ('c:\mybmp.bmp'),the project runs ok.
i can't tell why it can happen and solve the problem.
