Question and Problem

[Electron]

I have a form with a control on it and a class. I want to call the class and then in the class change one of the controls properties without creating a new form.

 

This is the code in the class:

Public Class Test
   Sub Change()
       Dim f As New Form1()
       f.cmdStart.Text = "Worked"
       f.Show()
   End Sub
End Class

 

This is the code in the form:

Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
       Dim t As New Test()
       t.Change()
End Sub

 

This is a very simple test so I know how to use it and then can apply it to a more complex program

 

Thanks a head of time

Change your Change subroutine to accept a parameter of type Form1, and then call it from the form passing Me. You can then adjust the form's instance to your heart's content.

Sorry, I am somewhat new to VB.Net. Could you give me some code on how to do that?

 

Thanks

This is very much appreciated

change your class to this:

 

Public Class Test
   Sub Change(ByVal f as Windows.Forms.Form)
       f.cmdStart.Text = "Worked"
       f.Show()
   End Sub
End Class

 

Now you just have to pass in the name of the form when calling this, you probably will use Me as the form name.
