Open a panel in a different app

Thanks for the example, The reason for opening a panel in another app, is because my program can be purchased in two parts (i.e. the main program and an add-on). I want to programmatically add code to the main program to open a panel and or code from the add-ons. I can't add this code at design time because there is no knowing what add-ons I might develop

Here is a very small example In one file, pnl.vb have: Public Class pnl1 ....Stuff in here, including public constructor, and whatever other controls you may need End Class Then, in another file for your forms, you would add the panel to a form as you would anything else. dim myPanel as new pnl1() myfrm.controls.addrange(New System.Windows.Forms.Control(),me.myPanel) myPanel.Dock = System.Windows.Forms.DockStyle.Fill Note: this isn't getting the panel from the .exe as you were for the form. I don't like relying on an external .exe file. If that exe file will always be at that location, and deployed as part of a package, it would be best to re-use the same code and compile the exe with that code. Hope this helps

Thanks, I'm not quite sure I completely understand, though. I'm still learning. Could you give a simple example?? I really appreciate your time!

you would need to have reference to the class pnl1 in the other project, then you could add it to the form's controls property.
