Waiting for an event

[Jon Cosby]

I have a form that needs to take input from another form. Problem is I can't
see any way to pause the sequence in the main form to wait for input from
the second form.


prompt = new AddressPrompt();
prompt.Show();
// Wait for click event in prompt
if (prompt.okay)
address[index] = prompt.addressInput;


Is there any way to do this? I've thought about creating a public method in
the main form, but I don't think there's a way to reference the open window.

So, you are basically trying to show a dialog, then use information that the
user input into the dialog to continue your processing?

If that's correct, it sounds as though you want to show the AddressPrompt()
form modally.
Do a couple of things:

On "Ok" button on the AddressPrompt form, set its DialogResult property to
Ok. Set the Cancel Button's DialogResult to cancel. You can do this in the
form designer.

Then, you can use this code:
prompt = new AddressPrompt();
// show the prompt modally, and check whether the user
// selected Ok or cancel:
DialogResult result = AddressPrompt.ShowDialog(this);
if(result == DialogResult.OK)
address[index] = prompt.addressInput;
else
// user cancelled the dialog
