Ive created an MDI application that has one parent form with a menu bar on the top. When a user selects the new option from the menu, the application brings up to child forms, one of these forms contains four buttons - like a tool box, the form is black.

My application should allow the user to press on of the buttons on the toolbox form and draw an item onto the blank form. I have of course created a graphics object on the black form which is passed to any class that needs it.

The problem is once I press the button nothing appears in the black form, I think these may have something to do with focus - but as this is the first MDI app Ive created Im not to sure

Any ideas why I am not getting a result

Thanks for you time
