The new VB 2.0 MDI support is fantastic ! True Form inheritance, autosizing toolbars etc. etc.... But: How do one manage to reference local varibales within a Form from outside ? Problem: Assume a drawing form, that contains local variables (declared in the Declaration section of the Form). These variables describes the picture that is shown on the Form. When making instances from this Form, anything works fine: every Form contains its own set of variables. But: If you want to write a save-and-load logic for these Forms, you can not reference these Form-local variables from outside the Form (eg. the MDI-Desktop). Is there any way to reference instance-variables of a Form ? Something like ActiveForm.MyArray(1).MyName ? The only workaround so far I found is a very clumsy setup: - define a Button within the MDI-child - make this Button invisible - attach the Load or Save function to this Button - "Click" this button (in the ActiveForm) from the MDI-menu option The problem still remaining is that I can't pass parameters to the Form- local procedure (execpt using the Tags from invisible controls). Any hints ? Hajo Schmitt Technical University Darmstadt

Hello All, Im hoping that some one out there in net land, would be able to help me. I am tryying to use, some C librarys from KENSMEN (sp) corporation, to develop some C++ Windows programs. I am using Borland C++, and OWL. Im wondering if any one has tried either this package, or something like it. I seem to have problems creating the status window. The manual says that I should use a call to CreateWindow, to accomplich this, but I have no idea at what point I should be doing this... If anyone has a clue, or a hint of what I should be doing, please email me directly Thanks very much. Alex axs9017@hertz.njit.edu

Sorry! You can not use variables outside its form or module except you use
Global variable....
