> As Vince told you, a Public variable would be visible to both forms. On the other hand, that public variable would also be visible to any other form. The more forms or procedures that can see that variable, the more risk that those forms could modify the value in that variable. I do NOT like public variables. A better way to go is with a private variable. When you call your forms, you can

and you will have just placed This.Value into a textbox on the other form.

to add up, you can also try the following.


in form1.cmdButton.click()

DO FORM form2 NAME ofrm

you can now set properties of form2 including it's objects. like:

ofrm.text1.value = [some value]
ofrm.caption = [some caption]
