I'm writing an application.I want to run process step by step from text variable and then show it on a textbox. Here my code:

void RunCmd(string cmd){
    StringCollection values = new StringCollection();
        p = new System.Diagnostics.Process();
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardInput = true;
        p.StartInfo.RedirectStandardOutput = true;

        p.StartInfo.FileName = @"cmd";
        p.StartInfo.Arguments= cmd;
        p.StartInfo.CreateNoWindow = true;
        p.Start();

        p.OutputDataReceived += (s, e) => {
            lock (values) {
                values.Add(e.Data);
            }
        };

        p.BeginOutputReadLine();
        foreach (string sline in values)
            txtresult.AppendText(Environment.NewLine + sline);
}

void btnAction_Click(object sender, EventArgs e)
{
    RunCmd("/c test.exe ABC && test.exe A5");
    RunCmd("test.exe 22");
}

It not working.Txtresult is empty

what do you mean by form is hidden?? – usamazf Mar 11 '16 at 11:13
`start.CreateNoWindow = true;` will hide your application... – CodeCaster Mar 11 '16 at 11:13
I mean mainform don't display.I can't see it – Jandy Mar 11 '16 at 11:16

Your sample isn't complete it seems - for example RunCmd is declared as without any params but you're passing in a string ? – auburg Mar 11 '16 at 11:20
I suspect reader.ReadToEnd() is blocking - have you tried putting a breakpoint on that line and seeing if that's the case ? Does result contain anything ? – auburg Mar 11 '16 at 11:34
yes,string result is null.Any idea – Jandy Mar 11 '16 at 11:51
You may need to modify your code along the lines of this http://stackoverflow.com/questions/15032643/get-values-from-process-standardoutput – auburg Mar 11 '16 at 12:03
