How to activate a form?

[Ebilum]

I know in VB 6.0 the code to activate a form was...

Private Sub cmdOK_Click ()

frmMainForm.Show

End Sub

How can I do the same in VB.Net?

Thanks

Dim frm As new Form1 ' <-Name of the form to load
frm.Show

In .NET, in order to display a form, you first must create an instance of the class.

    Dim frm As frmMain   ' Allocate memory on the heap for for object    
    frm = New frmMain()  ' Call class constructor to create and place object in heap

I tried the above code but it gave me an error. Something like, Value of .... can not be converted into a one dimensional array. Can any body break it down some more for me?

post the code you used (Cut / paste)

Here is the code I'm useing:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Click on button to open up Form2
Dim MainFrom As New Form2()

MainForm.show()





End Sub

Dim MainForm As Form2
MainForm = New Form2()
MainForm.Show()

[Static]

is Form2 called form2??


Dim frm As New Form1
frm.Show()


I dont get the () after the dim frm etc...hmmm

odd that it wouldnt work for you...


Hellswraith...if you do it like the code above.. you eliminate a whole step

He did that in two lines because if you use NEW in the declaration line then it has to check to see if it has been created everytime it access the object. At least that is the way it was in VB6, I'm not sure if .NET is smarter or not. I hope it is considering everything is an object. By setting it on the next line it removes that check thus speeding up access to the object.

Edneeis,
Both ways of creating an object are equivalent in .NET. No longer is the additional overhead required when accessing an object this way.

Good because I stopped doing it in .NET and always found it a bit annoying.

I tried to do this code in the form of Form 1 to load the Form2

Dim MainForm as Form2

(Then in the sub procedure)
Private Sub cmdOK_Click()
'Open up Form2

MainForm = New Form2
MainForm.Show

End Sub

This is exactly how I have it, and for some reason it gives me an error saying that "MainForm" is undeclared. Any body got any ideas?

[Edneeis]

Why do you have the declaration of MainForm outside of the sub?

Try this:

(Then in the sub procedure) 
Private Sub cmdOK_Click() 
'Open up Form2 
 
Dim MainForm as New Form2()
MainForm.Show 
 
End Sub
