.NET Forum / Windows Forms / WinForm General / June 2004Forms in Class Libaries
I have a class lib, that creates and shows a form. When the main app is minimized the form from the class lib isn't. Also when pressing Alt+Tab the class lib form shows in the window selection. How do I make it minimize when the application is minimized and not show in the alt+tab window? Thanks Wayne Hi Wayne, First set the lib form ShowInTaskbar property to false. Second befre showng the lib form set its Owner (not Parent) property to reference the application main form  SignatureHTH Stoitcho Goutsev (100) [C# MVP] > I have a class lib, that creates and shows a form.

Guess what I need to know is from the Form in the class lib, how do I get the applications main form? Not sure if this matters, but the class libs are dynamiclly loaded at run time. They are not referanced in the main application. These are for my in the works plugin system. Thanks Wayne > Hi Wayne, > [quoted text clipped - 13 lines] > > Thanks > > Wayne Hi, Wayne How class libs are loaded if they are not referenced? When you create classes from class libs, you can pass parent form reference, for example in constructor parameters. Or through any interface methods you defined - if any. HTH Alex > Ok, how do I do this? > [quoted text clipped - 23 lines] > > > Thanks > > > Wayne Basiclly I look for files in the source dir with a given ext. I then use Assembly.LoadFrom(fileName) to load the assembly. From there I ittirate through all the types contained in the assembly looking for types that inherit from my base class. When Found I create an instance of the type and add a menu item for that type, setting the on click of the menu to a method of the new instance. When the user clicks the menu item it does what ever was in the assembly to be done. Currently there is no way in my set up to pass the main form, The app I have has already been deployed and not sure how difficult it will be for me to have to change the class interface that is being used with in the app. Hope the above makes sense.

Anyways try to use Process.MainWindowHandle and then Control.FormHandle or Control.FromChildHandle. However I don't know how it works in the cases where the process host more than one AppDomains or the process has more than one top level windows. What internaly this property does is to enumerate all top level windnows and returns the first one which is created by a thread in the process.
