Cross Thread problem C#
- by Frederik Witte
Hello people - I got this code (lg_log is a listbox, and i want it to log the start_server.bat) Here is the code i got:
public void bt_play_Click(object sender, EventArgs e)
{
lg_log.Items.Add("Starting Mineme server ..");
string directory = Directory.GetCurrentDirectory();
var info = new ProcessStartInfo(directory + @"\start_base.bat") {UseShellExecute = false, RedirectStandardOutput = true, CreateNoWindow = true, WorkingDirectory = directory + @"\Servers\Base"};
var proc = new Process { StartInfo = info, EnableRaisingEvents = true };
proc.OutputDataReceived += (obj, args) =>
{
if (args.Data != null)
{
lg_log.Items.Add(args.Data);
}
};
proc.Start();
proc.BeginOutputReadLine();
lg_log.Items.Add("Server is now running!");
proc.WaitForExit();
}
When i run this, i'll get an error .. Anybody can help me? I'll rate the answer up! :D
Edit: The error i get is this: System.InvalidOperationException Hope it helps :)
The error comes at the lg_log.Items.Add(args.Data); code line
