Handling arrow keys on a VB windows form is a pain until you find a solution that works according to your needs:) Well I posted this coz I got excited having solved a problem I had with detecting the arrow keys in VB.NET. I've been struggling to detect the arrow keys on a windows application form that I was designing in VB 2008.
The form contained a TabControl and needed to detect the keys only on TabPage1. Since there were many other controls on the form I had to use an overriding function.
i.e:
Protected Overrides Function ProcessCmdKey(ByRef msg As Message, _ ByVal keyData As Keys) As Boolean
' detect which key is pressed and perform some action
End Function
The problem is that TabPage2 contained a textbox and would allow me to enter only a single character. To continue typing into the textbox I needed to click in the textbox and type the next character. To overcome this problem I needed to check which TabPage had the focus. But the problem was where to check the focus.
