*Resolved*What we used to do in VB6, to show a form?

[veryjonny]

form2.show

now if I have say a button(toolbar) and a menu item which calls his same form? on the clicks event - I just call formname.show. Thats it.

Come VB.NET

To display a form we use:

dim frm as new form2
frm.show

Prob: Now if some one clicks on the button twice or say once on the button and then in the menu item - then as many instances of form2 are created and displayed - how do I STOPPPPP this?

Dont declare the new form there! You could declare your forms in a module instead!

Public Module TestModule

           Public frm as new Form2

End Module


Public Class Form1

     Public Sub LoadForm2

           frm.Show

     End Sub

End Class

I don't understand why so many people have trouble with this. I'm also a newbie at VB.NET (finnished my book just a couple of weeks ago).

Me too a newbie.
But doesnt declaring the way u suggest load the form in memory even before I need it?

[MrPolite]

well if you dont need to access the form in the module then just do it all at once:

dim frm as new form2
frm.show

I guess, but so what?

If you really need to, you could always check if the form has been loaded already.

Public Class Form1

     Dim frm As Form2

     Public Sub ShowForm
    
          If frm Is Nothing Then
          
               frm = new Form2();
         
          End If

          frm.Show

      End Sub

End Class

yes. Thats what I was missing.
