the scope of new form instance

[AndrejZ]

i create an instance of form with the code:

Dim formA as New Form1

then i enable formA. In some cases i would like to disable formA, then enable Form2, perform some tasks and then enable formA again. But in form2 there seems that formA is an unknown object?

whereabouts have you declared formA? you should declare it in a standard module like this:

Public formA As New Form1
