Question

I am new to C# programming. I would like to have an application contains 1 text box and 1 submit button to exec a batch file.

The file is d:\XMLupdate.bat, but the program appends a number on the command line to the file
for example d:\XMLupdate.bat 10 or d:\XMLupdate.bat 15

Another thing is that the submission has to be validated to either 1 -999 or ALL

In Java way:

 Runtime rt = Runtime.getRuntime();
                            Process pr = rt.exec(command);
                        }
                else{
                try{
int boxNumber = Integer.parseInt(jTextField1.getText());
                        if((boxNumber > 0) && boxNumber < 1000)
                            {
                                String arguments = jTextField1.getText();
                                String command = "CMD /C start d:/XMLupdate.bat " + arguments;
                                Runtime rt = Runtime.getRuntime();

rt.exec(command);

                            }
                         else{
                            JOptionPane.showMessageDialog(null, "Invalid value entered.");
                            }
 }catch(Exception e)
                        {
                            JOptionPane.showMessageDialog(null, "Invalid value entered.");
                        }
                    }

However, the machine can not install JVM. Therefore, i have to build it in exe. My programming language is C#:

Here is the source code:

public partial class Form1 : Form
    {

        //private System.Windows.Forms.TextBox textBox1;  //Input text
        //private System.Windows.Forms.Button button1;   //Sumbit button

        public Form1()
        {
            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)
        {
            //get text
           // string str_inputText = textBox1.Text;
            if (!(textBox1.Text.Equals("")))
            {
                  if (textBox1.Text.Equals("ALL"))
                      {
                          try
                          {

                              Process p = new Process();
                              p.StartInfo.FileName = "CMD.exe"; //Execute command
                              p.StartInfo.WorkingDirectory = "c:\temp"; //Diretory
                              p.StartInfo.Arguments = "xmlupdate.bat" + int.Parse(textBox1.Text);
                              p.Start();

                              p.WaitForExit();

                          }

                          catch (Exception ex)
                          {

                              Console.WriteLine("Exception Occurred :{0},{1}", ex.Message, ex.StackTrace.ToString());
                              MessageBox.Show("Invalid value entered");

                          }
                      }

            }

        }

        private void textBox1_TextChanged(object sender, CancelEventArgs e)
        {


        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            //Check the input number, only allow from 0 until 1000
            try
            {
                int numberEntered = int.Parse(textBox1.Text);
                if (numberEntered < 1 || numberEntered > 10)
                {
                   // e.Cancel = true;

                }
            }
            catch (FormatException)
            {
               // e.Cancel = true;
                MessageBox.Show("You need to enter a number between 1 and 999");
            }
        }

    }

My main question is about process method, can i execute it like that? thanks

Answer 1

“can i execute it like that?”

1. Does your solution compile?
2. If so, what happens when you run it?

On thing I noticed off the bat is this line

 p.StartInfo.Arguments = "xmlupdate.bat" + int.Parse(textBox1.Text);

You need a space between the batch file and the next argument.

 p.StartInfo.Arguments = "xmlupdate.bat " + int.Parse(textBox1.Text);
