NooB Question

Hello all,

I'm teaching myself VB .NET and I am having a bit of an issue.

I have a Form with two buttons...

Button 1 is where I capture the path and file name using OpenFileDialog.
Button 2 is where I want to process the file I captured from button 1.

I do not seem to be able to pass the file name from button 1 to button 2.

is there an Easy way to do this?

Thanks in advance,

-NJ

Well there is but why would you need to? Button1 opens the filedialog, you get the filename, so why not just process it as a continuation of that sub? Button 2 appears to have no raison d'etre (oooh, hark at me coming over all posh!)

You can assign the file path you got from the OFD to a string variable and then use that variable with button2.

edit: VS is taking foreverr to load, so this is freehand:

Public Class Form1
 
    Dim filepath As String
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        OpenFileDialog1.ShowDialog()
        filepath = OpenFileDialog1.FileName
 
    End Sub
 
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
 
        MessageBox.Show(filepath)
 
    End Sub
End Class

Yes, as long as the variable is NOT declared within one of the button click event handlers, then it is visible to the other click handler. The problem you may have been having is that you were holding the filename in a local variable within the click event handler, so the other click handler couldn't see it. This is called variable scoping, and is kind of important....but it's also a guess as to what you were doing on my part.

        MessageBox.Show(filepath)
 
    End Sub
End Class

That did it! Thank you
