Execute a .JAR file from VB. [Solved]

So i'm currently working on a minecraft Server GUI and i ran in to this little problem.

I dont know how i can open a .Jar applet file inside the visual basic.
or it could also be cool if i could open a batch/console In my GUI.

I don't mean that i want to decompile it i just want so the text that are being written once you open the .jar or the bach file are being also written in my GUI but without acctualy opening the file it self just trough the GUI.

Hope i Explained it well...

Didn understand nothing...

Ex: You want to read the .jar content and put in a textbox? or what?

Ill Upload pics just in a minute ;D to show what i want help with

This is what i mean

Hope u guys can help me

You want the text that is in the cmd window?
So here: ( I dont have time to explain it..)
Import the System.Text

Code:

Dim Processo As New Process Dim ProcInfo As New ProcessStartInfo(YOUR PROCESS, PROCESS ATRIBUTES ) Processo.StartInfo = ProcInfo ProcInfo.UseShellExecute = False ProcInfo.RedirectStandardError = True ProcInfo.RedirectStandardInput = True ProcInfo.RedirectStandardOutput = True Processo.Start() Dim CMDString As New StringBuilder Dim ReadingCMDString As IO.StreamReader = Processo.StandardOutput While Not ReadingCMDString.EndOfStream Dim Line As String = ReadingCMDString.ReadLine Try If Not Line = vbNullString Then CMDString.AppendLine(Trim(Line)) End If Catch ex As Exception End Try End While ReadingCMDString.Close() Processo.WaitForExit(1) TextBox1.Text = CMDString.ToString Catch ex As Exception End Try

Thanks

Too Short

Got a new Problem when i have this code in and i start thr program and and i click the button to open the cmd it start's the cmd it self

i dont need it to star only type in the text that the cmd is typing. and once it acctualy is open nothing happens in the cmd.? this is my code

Code:

 Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
        TextBox3.Text = OpenFileDialog1.FileName
        Dim Processo As New Process
        Dim ProcInfo As New ProcessStartInfo(TextBox3.Text)
        Processo.StartInfo = ProcInfo
        ProcInfo.UseShellExecute = False
        ProcInfo.RedirectStandardError = True
        ProcInfo.RedirectStandardInput = True
        ProcInfo.RedirectStandardOutput = True
        Processo.Start()
        Dim CMDString As New StringBuilder

        Dim ReadingCMDString As IO.StreamReader = Processo.StandardOutput

        While Not ReadingCMDString.EndOfStream
            Dim Line As String = ReadingCMDString.ReadLine
            Try
                If Not Line = vbNullString Then
                    CMDString.AppendLine(Trim(Line))

            Catch ex As Exception

            End Try


        End While
        ReadingCMDString.Close()

        Processo.WaitForExit(1)
        Try

You want it in real time? The code? Idk how to do that..Wait for the pros..

Read the stdout of the process which you can start via. System.Diagnostics.Process.Start, and passing it a StartInfo that specifies for the StandardOutput to be redirected to your app (which you can read via. a SteamReader).

Lol spam.

Hmmmmmmm......

Well i Understand NOTHING

could you make an example?

Try the following if you just want to have the window in your own program:

[highlight="VB.NET"]Imports System****ntime.InteropServices
Imports System.IO

Public Class Form1

#Region "DLLImports"

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _

End Function

<DllImport("user32.dll")> _
Private Shared Function GetWindowLong(ByVal hWnd As IntPtr, ByVal nIndex As Integer) As Integer
End Function

Const SW_MAXIMIZE As Integer = 3
Const GWL_STYLE As Integer = -16

#End Region

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WindowToPanel("C:\Dokumente und Einstellungen\Xerxes\Desktop\random.bat", Panel1)
End Sub

Dim pProcess As New System.Diagnostics.Process

Private Sub WindowToPanel(ByVal Filepath As String, ByVal Panel As Panel)
Panel.Visible = False
Try
pProcess.StartInfo.FileName = Filepath
pProcess.StartInfo.WorkingDirectory = Path.GetDirectoryName(Filepath)
pProcess.StartInfo.WindowStyle = ProcessWindowStyle.Minimized
pProcess.Start()

SetParent(pProcess.MainWindowHandle, Panel.Handle)
ShowWindow(pProcess.MainWindowHandle, SW_MAXIMIZE)

Dim frm As Integer = GetWindowLong(pProcess.MainWindowHandle, GWL_STYLE)
SetWindowLong(pProcess.MainWindowHandle, GWL_STYLE, frm And Not 12582912)

Panel.Visible = True
Catch ex As Exception
MessageBox.Show(ex.Message.ToString(), "Info")
End Try

Panel1.Visible = True
End Sub

IDK how you did it. The code is not getting me any errors but once i run the program it just opens the cmd in a new window not inside my application this is my code.

Well, Ya. That's what i wanted but apparently i can't get help with that.

You did get help with that...you just chose to ignore it because it wasn't a direct spoonfeed.

As simple as can be:

[highlight=vb.net]
Private Function readProcessOutput(ByVal filePath As String) As String
Dim retVal As String = String.Empty
Dim proc As New Process With {.StartInfo = New ProcessStartInfo With {.FileName = filePath, .RedirectStandardOutput = True, .UseShellExecute = False}}
proc.Start()
Using sRead As IO.StreamReader = proc.StandardOutput
retVal = sRead.ReadToEnd
End Using
proc.WaitForExit(0)
Return retVal
End Function
[/highlight]

All you need to do is plug in the location of the process, and then assign the result to a textbox:

[highlight=vb.net]
TextBox1.Text = readProcessOutput(Environment.GetFolderPath(Enviro nment.SpecialFolder.Desktop) & "\test.bat")
[/highlight]

Doesn't come any simpler than that.

Thank You alot

Could you just help men once again

Code:

TextBox1.Text = readProcessOutput(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) & "\test.bat")

what if i want to open the batch file froms some other folder then desktop.

You only need to use the Environment.GetFolderPath for paths like ApplicationData, Desktop etc..

You can just put in a regular file location:

[highlight=vb.net]
TextBox1.Text = readProcessOutput("C\Users\Jason\Documents\test.ba t")
[/highlight]
