Body
copied!<p>I'm Re-Creating the "command prompt" into a Windows Form. The application is not working properly; and i can't figure exactly why.</p> <p>When the form Loads it is suposed to run the cmd.exe (Load the cmd info into "TextBox_Receive"), but it doesnt; and also after writing any command in the "textBox_send" (that sends input); it will only show input after pressing "Enter" key 2 or 3 times.</p> <p>Any idea what i am missing here?</p> <pre><code>public partial class Form1 : Form { // Global Variables: private static StringBuilder cmdOutput = null; Process p; StreamWriter SW; public Form1() { InitializeComponent(); textBox1.Text = Directory.GetCurrentDirectory(); // TextBox1 Gets the Current Directory } private void Form1_Load(object sender, EventArgs e) { checkBox1.Checked = true; // This checkBox activates / deactivates writing commands into the "textBox_Send" cmdOutput = new StringBuilder(""); p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.UseShellExecute = false; p.StartInfo.CreateNoWindow = true; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.EnableRaisingEvents = true; p.OutputDataReceived += new DataReceivedEventHandler(SortOutputHandler); p.Start(); SW = p.StandardInput; p.BeginOutputReadLine(); p.BeginErrorReadLine(); } private static void SortOutputHandler(object sendingProcess, DataReceivedEventArgs outLine) // I dont actually understand this part of the code; as this is a "copy" of a snippet i found somewhere. Although it fixed one of my issues to redirect. { if (!String.IsNullOrEmpty(outLine.Data)) { cmdOutput.Append(Environment.NewLine + outLine.Data); } } private void textBox1_KeyPress(object sender, KeyPressEventArgs e) { // Send "Enter Key" - Send Command if (e.KeyChar == 13) { SW.WriteLine(txtbox_send.Text); txtbox_receive.Text = cmdOutput.ToString(); txtbox_send.Clear(); } } private void checkBox1_CheckedChanged(object sender, EventArgs e) { // Enable / Disable Sending Commands if (checkBox1.Checked) txtbox_send.Enabled = true; else txtbox_send.Enabled = false; } } </code></pre> <p>}</p>
