Question Showing Console Output On Label Is Not Working

[SiamIT]

Greetings,

i am just trying to show the console output to label text. but it's just not working..

i have tired hours and hours of this and that but none is working.. and now came here for support

here is the code i have tried so far:

        private static void ExecuteCLI(string[] args, string workingDir, Form form, Label label)
        {
            List<string> lArgs = new List<string>(args);
            lArgs.RemoveRange(0, 3);

            string cliFile = args[2];
            string cliArgs = string.Join(" ", lArgs.ConvertAll(item => item.Contains(" ") == true ? '"' + item + '"' : item));
            //create working directory if not exits
            if(Directory.Exists(workingDir) == true && isIde == true)
            {
                label.Text = "Deleting Working Dir...";
                foreach(string filePath in Directory.GetFiles(workingDir, "*.*", SearchOption.AllDirectories))
                {
                    new FileInfo(filePath).Attributes = FileAttributes.Normal;
                    File.Delete(filePath);
                }
                Directory.Delete(workingDir, true);
                label.Text = "Status Goes Here...";
            }
            if(Directory.Exists(workingDir) == false)
            {
                Directory.CreateDirectory(workingDir);
            }

            Process process = new Process()
            {
                StartInfo = new ProcessStartInfo()
                {
                    FileName = cliFile,
                    Arguments = cliArgs,
                    UseShellExecute = false,
                    WindowStyle = ProcessWindowStyle.Hidden,
                    CreateNoWindow = true,
                    RedirectStandardOutput = true,
                    WorkingDirectory = workingDir,
                },
            };

            process.OutputDataReceived += delegate (object sender, DataReceivedEventArgs e)
            {
                if(e.Data == null)
                {
                    return;
                }
                string cliMSG = e.Data.Trim();
                if(cliMSG.StartsWith("Extracting") == true)
                {
                    System.Diagnostics.Debug.WriteLine(cliMSG); //if no method is used, it's shows the output on debug/output window just fine..
                    
                    //sUpdateAddressBar(form, label, cliMSG); (3rd Method, crash/keeps loading forever without updating)
                    
                    //setLabelText(label, cliMSG);  (2nd Method, crash/keeps loading forever without updating)
                    
                    /* // (1st method though don't crash the app, just don't updte the
                    form.BeginInvoke((Action)(() =>
                    {

                        label.Text = cliMSG;
                    }));
                    */
                }
            };
            process.Start();
            process.BeginOutputReadLine();
            process.WaitForExit();
            process.Dispose();

            form.DialogResult = DialogResult.OK;
        }

        private static void setLabelText(Label label, string text)
        {
            if(label.InvokeRequired)
            {
                label.Invoke((System.Action)(() => setLabelText(label, text)));
            }
            else
            {
                label.Text = text;
            }
        }

        private delegate void sCBUpdateAddresBar(Form form, Label label, string text);
        private static void sUpdateAddressBar(Form form, Label label, string text)
        {
            if(form.InvokeRequired)
            {
                form.Invoke(new sCBUpdateAddresBar(sUpdateAddressBar), form, label, text);
            }
            else
            {
                label.Text = text;
            }
        }

as i have noted in comments no method i have tried does works

here is the screen shot of crashed/loading forever: (i red marked the area to identify the cursor)

can any one suggest me what i am doing wrong? here?

best regards

My first guess would be that process.WaitForExit(); is blocking the Ui thread so the invokes won't work (you're invoking so that you can update the UI from a non UI thread which is good, but if you block the UI thread anyway it won't be available to draw the UI when the invoke is done)
