Hi,

Thanks for clicking.

I've converted over my appication from vb6 to vb.net.

As part of the upgrade wizard it uses DefInstance property to reference controls within a form from outside that form.

I've hit problems with DefInstance when initializing a new instance of a form. In short it ends up in a repeating loop due to the initialisation of the form calling DefInstance for a control before form has been initialized properly

Is there a way around using DefInstance?? How are controls referenced from outside that form if creating vb.net project from new.

Hard to tell without seeing more information about what the converted code looks like.

In VB.NET, you need to have an instance variable to reference something on a form.  That is what DefInstance is supposed to do.  If you are starting with a VB.NET application, you would dimension a variable, and then reference the properties and methods from the variable:

Dim frm As New Form1
MsgBox(frm.TextBox1.Text)

Hi Bob,

Noticed this is still open.

Just for your knowledge. Have removed DefInstance by Form1.DefInstance with m_Form1.

Public m_Form1 As Form1

and then

m_Form1 = New Form1

Thanks as always for your help
