VC++.Net DialogBox

P: n/a
Hello Everybody:

I am trying out DialogBox, and I have been trying to press the
OK Button on the dialogbox hoping I can receive the OK DialogResult
to Main Form. Below is my OK button click event handler code on
AboutBox Dialogbox:

DialogResult = DialogResult::OK;

It can also dismiss the dialogbox and return OK "Ideally".

But I can't get the OK value from the main form, instead I keep get
the
None value in DialogResult. Anybody helps me please.

The result is in the return value of ShowDialog. this->DialogResult would be
where you *set* the result if Form1 was modal.
