My application's main form has a status bar that displays user changeable information, setup com ports, gpib stuff, etc. This forms controls (menu and toolbar) creates several other forms that modify these settings which should update the main forms status bar. I have a method in the main form class called UpdateMainStatusBar(). In the close event for the dialog forms I would like to be able to call this method to update the main form status bar but I keep getting compile errors because the dialog form class cannot see this method. I have tried making it a public method to no avail. Can anyone help with this?
Thanks,

You will have to cast the variable that holds the reference to your main form class to the type of your main form class to let the other clssses see the function you are trying to call.

E.G. if your main form classe's name is form1 and you are passing the reference of your main class form to other classes as a Form type variable you will have to cast this varible to Form1 before you could call the function you are trying to call.


The neater way however, of doing what you are trying to do is to create a kind of callback function in your main class to update the statusbar and pass references to it ( through delegated) to the other classes.
