• Windows Forms How to delete collection entries when control deleted?

  I have created a custom control that exposes a collection property. The collection is edited using the standard collection editor at design time and all works as expected. So when you add a couple of new entries to the collection the generated code creates the two new instances and adds them to the collection. Great. But if I select the custom control instance and delete it then it does not also delete the two entries that were created for the collection. They are still declared as private variables and created. How do I ensure that the dependant entries are removed when the custom control is also removed Phil Wright http://www.compone ...Show All

• Visual Studio Express Editions Variable Recreation

  Hi, a dumb question from a newbie. I have an Mdi appication in which i declare variables at the start of the class as below: Try declaring your forms without the NEW keyword. DIM Childform1 as Child Then create it in your sub-routine with Childform1 = new Child ChildForm1.MdiParent = Me ....................etc I'm not sure if this will give you the desired effect as it is a bit hard to understand what your are trying to do as normally the "Window | Tile Horizontal" command is used to arrange forms which are already open and you seem to want to create a new form each time it is used.
