Question

Answer 1

+1 A:

Forms are just classes and can therefore be instantiated explictly (and you will probably find your life easier if you do rather than using the automatic instantiation in VB6) and references to forms can be assigned.

You can solve your problem by creating a public property on your child dialog (Form1.frm) of type Form that you set to the instance of the parent dialog thus giving you access to the controls andd methods on the parent from the child.

My VB6 is somewhat rusty (and I don't have an installed instance available) so this isn't going to be actual, correct code - but something along the lines of the following should work

In the code that calls the child:

Form childDialog = new Form1
childDialog.Parent = this
childDialog.ShowModal

Then in the child dialog:

Parent.txt_c1 = newValue
if not Parent.Validate then
...
end if

Not a bad try at VB6, I'm guessing you've moved to C#? I think you mean something like `Dim childDialog As Form1: Set childDialog = New Form1: Set childDialog.Parent = Me: childDialog.Parent.Show vbModal` and then `Parent.txt_c1.Text = newValue: If Not Parent.Validate Then` I would also guess that jaminator may need to make `txt_1validate` Public
