How to read the value from textbox and use as file path?

[polimer]

Hi all,

I am a beginner in Visual Basic. I use Visual Studio 2008.

I don't know how to solve this problem.
I would like to run a file name xyz.exe from "c:\test\number\" directory.
I have a browse button (Button3) to set the working directory ( c:\test\number\), and the path is shown in my TextBox1.
I would like to get the Run button (Button1) to run the xyz.exe file from the previously selected directory.


The code for Button3

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Dim BrowseFolder As New FolderBrowserDialog
        BrowseFolder.ShowDialog()
        TextBox1.Text = BrowseFolder.SelectedPath
        MsgBox(BrowseFolder.SelectedPath)
    End Sub

The code for Button1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
               System.Diagnostics.Process.Start( "\xyz.exe")
    End Sub

Can you please help me to solve this problem?

Thank you

Poli

Slightly odd way of going about it but ...

Process.Start(TextBox1.Text & "\xyz.exe")

Great,
Thank you.

Only one more question:
How can I make that if the selected folder doesn't contain the file a msgbox says there is no file in selected directory and after hitting OK, it goes back to my panel and not freeze?

Thank you again for your help

Take a look at the various classes in System.IO. There should be a path object, and a file object (though one of those may not actually be an object). You can use the tools in there to figure out various things, such as whether or not the user entered a valid path, whether or not the file exists, and so forth. You want to check out that entry before calling Start.
