VB has predefined constants for most every key on the keyboard; do a search in VB Help or the Microsoft site for "keycode constants". They're fairly mnemonic- the <CTRL> key is vbKeyControl, the "+" sign on the keypad is vbKeyPlus, etc.
You'll want to check in the KeyPress event for the form/control. Using a textbox for an example, it would look something like:
All you're doing is changing the keycode value from whatever they pressed (that you don't want) to Null (or whatever). They press the <CTRL> key, you change it to Ø (null), nothing happens in the textbox. If you want to trap for 2+ keys, either build an If...ElseIf...Else block or a Select Case statement.
