does anyone know how I can stop a user from closing the program if they click the "X" button of the Controlbox, but allow them to close the program by clicking another button? I don't want to make the "X" button invisible. I still want it to be there.

View 5 RepliesForm1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?
Dim frm As Form

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

View 4 RepliesIs there any way I can find the exact reason a form is closing ? To be more specific , I'd like to find when a form is closing :1) because the user pressed the X button on the upper right corner2) due to code (Me.Close , MyForm.Close etc)I know I can use the FormClosing event and use this code :If e.CloseReason = CloseReason.UserClosing Thenhowever it seems that the CloseReason.UserClosing catches both cases (closed by te X button or by code) . So , is there any way I can find exactly the reason a form is closing ?Back in VB6 , the correspondent UnloadMode variable of the Form_Unload event could be "vbFormCode" which indicated specifically that the form was closed by code

View 3 RepliesI have an MDI parent form and multiple child forms. Child forms are borderless and set to start in the maximized position because I want the forms to completely fill/resize within the parent form and only display the selected form, one form at a time.
Problem I have is whenever I load a form it puts another bar at the top of the screen and another control box. Is there any way to get the child forms to load in maximized state without this bar? I tried .controlbox = false and it gets rid of the control box but the bar is still there.
