Dialogs in Windows Forms application

[krajnik]

I am having trouble with a Forms application I'm writing. I have 3 forms: a main form, Form1, and two modal dialogs, Forms 2 and 3, that are called from the main form. The two dialogs are intended to change certain "control parameters" that are used by the main form to run a control algorithms. So I need the two dialogs to be able to set certain variables that are used by the rest of hte program. Also, when I open one of hte dialogs, the controls on that from should reflect the current state of those variables. I cannot figure out how to do this. I thought I could declare global variables that could be accessed by all three forms. That way, when I open a dialog, its controls would be set based on the current values of those globals. Then, when I close the dialog and apply the changes, those changes would be saved back to the global variables. I tried this, and I can't seem to define variables that are accessible to all the dialogs. Am I going about this all wrong? Can anyone help guide me in the right direction? ANy help would be greatly appreciated. Andrew Krajnik

I cant remember if windows forms has the OnInitDialog(), if so override that and for the closing of the dialog you can override OnClose(). when you overwrite onclose make sure you call DestroyWindow() from the parent class.
