Java Compiler

[sanjeev467]

I am Developing an application for my project in which i'm providing the users to enter their java code in a richtextbox & when user clicks on the run button I am showing the output of the programme in another richtextbox.But The problem is that i'm able to do so only for static programmes but not for the user intertactive programmes
wherein the user is asked to provide some input My code is :

Dim myprocess As New Process
        Dim runpath As String
        Dim path As String
        path = "javac " + TextBox1.Text + ".java"
        runpath = "java " + TextBox1.Text
        Dim StartInfo As New System.Diagnostics.ProcessStartInfo
        StartInfo.FileName = "cmd" 'starts cmd window
        StartInfo.RedirectStandardInput = True
        StartInfo.RedirectStandardOutput = True
        StartInfo.RedirectStandardError = True
        StartInfo.UseShellExecute = False 'required to redirect
        StartInfo.CreateNoWindow = True
        myprocess.StartInfo = StartInfo
        myprocess.Start()
 
        Dim SR As System.IO.StreamReader = myprocess.StandardOutput
        Dim SW As System.IO.StreamWriter = myprocess.StandardInput
        SW.WriteLine("set path=C:\Program Files\Java\jdk1.7.0\bin") 'the command you wish to run.....
        SW.WriteLine("cd C:\Users\abcd\Desktop\Cloudproject\javacodes") 'the command you wish to run.....
 
        SW.WriteLine(path) 'the command you wish to run.....
 
        SW.WriteLine(runpath)
        
        SW.WriteLine("exit")
       RichTextBox2.Text= SR.ReadToEnd 'returns results of the command window
        SW.Close()
        SR.Close()
    End Sub
