multiple windows

Question

NEED HELP! I am trying to write an application with several windows. Are there any samples that show how to do this. I am writing the app in C#. The app needs to be able to show different forms and resume processing on any of the other forms within the application. Each of the forms are created at design time.

Hi Felice I guess I have the answer what u r looking for. Well I work with vb.net but that doesn't matter. Concept will still be the same. First of all I don't like MDI. I go for a better approach. You can use a MODULE. This is damn easy. Add a module in ur project (you know how to add an item... don't you?). Name it as say... Global.vb (for VB.Net). It is nothing but a code editor. It doen't have an interface. Now open it and declare all of your existing forms in it (In the module section). For example: Public F1 As New Form1() Public F2 As New Form2() Public F3 As New Form3() *** Note: They should be public as you want to work with the contents or data from each form. Now add a main() into it and load the first form you want to show at the begining of ur application in it. Sub main() F1.ShowDialog() End Sub So far so good. Now you can call any function in a form class in any other form class provided u declared that function as Public. You can use any forms contron from a different form provided you changed the Modifier property of that control to Public. For example: to call a Calculate() function written in F1 from F2. just use F1.Calculate(). Same for the controls F1.TextBox1.Text=Blah Blah Well I don't any easier method for what u want to do. If u have something else... just let me know. Thank you... BAAN

I am not necessarily looking to continue processing on the other forms but using each form for processing the behaviour for the business function needed. I do have a version working with MDI but wanted to learn to do this using seperate forms. do you know of any sample code that will help me understand this?

If you are using several windows a good approach may be to useMDI (Multiple Document Interface). Basically you would have the main form and all others would load inside it (similar to excel) To have another form continue to process information from a different form you would need to have public methods available (like any other object). Hope this helps
