KeyDown handling?

If I press the Key "a" on the keyboard, all the events and properites will
only give me "65" as keycode.. and I want it to give me "a".

If I use the KeyPress event.. then I will have access to e.KeyChar which
will give me the "a" but I can't use that here.. I need to use the KeyDown..
since you can only capture ONE key in KeyPress and I'm looking for Several
Keys.

So I need to convert the KeyCode "65" into a Character... any ideas on how?

Regards

If you want to process chars, use KeyPress.
If you want to process keys, use KeyDown.

Why can't you use
if e.keycode = System.Windows.Forms.Keys.A then
?

Cause I have dynamic Hotkeys... the user can choose what To compare with so
I can's use the static comparision you suggested.

/Lars
 
The user fill a textfield in the preferences window of my application with
what letters (+ ALT) associated they want to use for certain functions.
Since that's a String I get from the USer I nee to get that into something
that I can compare with in the Event for the KeyDown.

If you know of a really good way of doing this without using my way I'm
happy to hear cause my solution feels a bit "ugly"

If Chr(e.KeyValue) = UserVariableAsString AndAlso (e.Alt) Then

Me.dgrResources.Focus()

ElseIf Chr(e.KeyValue) = UserVariableAsString2 AndAlso e.Modifiers =
Keys.Alt Then

Me.dgrCodes.Focus()

End If

Dim key As System.Windows.Forms.Keys
key = DirectCast( _
[Enum].Parse( _
GetType(System.Windows.Forms.Keys), "a", True _
), System.Windows.Forms.Keys _
)


But, instead of offering a way to input chars, I'd handled the KeyDown
event. Open the properties of a link in the explorer where you can input a
key combination. That's probably something I'd prefer as a user.

Lars,
I would consider creating a custom control for your preferences window that
has a property of type System.Windows.Forms.Keys that represents the key the
user presses.

The control would display a text representation of this using Enum.ToString.

The control would use the KeyDown event to store the keys used to create the
value.

This control would work similar to the "Press shortcut keys(s)" control in
"Tools - Customize - Keyboard" in VS.NET.

Hope this helps
Jay
