View 6 RepliesI have inherited support for a program written in VB2008
The problem I have is as follows:
Users have a low screen resolution (company policy) and so can't see the bottom of a particular form.
The bottom of the form has buttons that allow them to navigate between its' four pages so they need to be able to see them. This being the case I need to add a scrollbar to the form.
If I try to drag and drop a vscrollbar from the toolbox it just sits there at runtime (you can slide the button on the toolbar up and down but nothing happens regarding scrolling the page.
All the reading I have done seems to point to forms being given scrollbars in accordance to the AutoScroll, AutoScrollMargin and AutoscrollMinSize properties of the Form itself.
By setting these properties I can get scrollbars to appear in the IDE but they are not there at runtime.
I think I'm probably missing something really obvious here but, so far, have been unable to work out what it is.

The code above can access the database but it refuses to add,update,or delete any records..
Ive recently wrote a custom control which hosts other controls on its surface. These constituent controls are accessed through a collection property in similar vein to a DataGridView's columns. Now I find that whenever I delete the control from the designer, it leaves behind the code for the constituent controls when it should delete them as well just as the DataGridView columns would be deleted when you delete a DataGridView.
I also had similar problems with copying and pasting which were solved by implementing a designer for the main control and overriding the AssociatedComponents property to return the collection so that the designer would treat the components in the collection as children of the main control. This doesn't work when deleting the main control.
For the purposes of experimenting with this, I created a small projects with similar circumstances to focus specifically on the problem without all the baggage that comes with the real thing. I made a master control with a collection property that holds several objects that inherit from component similar to my real project. I created a ControlDesigner for this object as with the real thing. Even so I still cant figure out why deletions dont work.

This code works greatin VB6 but I can't for the life of me figure out how to accomplish this in the Visual Basic 2008.
