I am writing an application(MDI) that has a modless dialog box with a slider control on it.  As it moves I want to print a number 0-100 in the View window.  Can you give me some ideas on how to do this.

This is a classic case of Document-View Model.

You sould have a variable in your CDocument derived Object, That holds the current value of your slider, and methods to update it.

The dialog box should be able to call these methods each time the slide is bwing updated. (You can pass a pointer to the CDocument, or to make a function in the CWinApp theat will return the active document).

The CDocument function should call UpdateAllViews each time it changes the value of your variable.

The View should handle this event in the OnUpdate function.

That's a long description, but it is very easy to implement.

Good Luck!
