VS 2010 - Using KeyDown And E.KeyCode For Hotkeys

Jul 27, 2011

I'm working on a project that contains hotkeys, but I don't wish to have global hotkeys. At the moment, I'm using KeyDown and e.KeyCode for hotkeys. I've created test projects where these worked perfectly fine, but on my main project, they don't register.

VS 2010 E.KeyCode - Determining Which Was Pressed

Nov 10, 2011

I'm trying to determine when the 'Left' and 'Right' keys are pressed, for keys that have a counter part. Like, Shift, Alt and Control. But it doesn't seem like any the counter parts have a unique KeyCode or KeyData. If I press the right or the left keys, I get the same KeyCode each time:

Multi Key Hotkeys In VB 2010?

Feb 24, 2012

I've written a simple WAV player in VB 2010 - a Windows Form App with no menus. I'm trying to create a hotkey, like CTRL-D that would make a text box visible. Typing the correct password in the box will expand the form and show some Administrative functions. I'm having issues creating the hotkey with more than one key.I've got the following code, but it does not work. I do have KeyPreview set to True.

Private Sub _KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.Control And e.KeyCode = Keys.D Then
txtPWD.Visible = True

I've also tried

If e.Keycode = Keys.ControlKey & e.KeyCode = Keys.D

and many other variations including changing to ALT and SHIFT but nothing seems to work. If I remove one of the Keys, it works just fine.

VS 2008 KeyCode For Multiple Buttons

Jul 26, 2010

I'm just trying to learn alot of the tricks and such so I'm making small programs and games to just get the swing of things.I'm having abit of trouble with this one, currently. I'm tying to create a form with two buttons. Now, I want to be able to press two keys on the keyboard and have one of the two buttons activate So, instead of clicking Button1, I pressed Control + C and it will say "Comment" and instead of clicking Button2, I press Control + U and it will say "Uncomment".

Public Class Form1

[code]...

The problem I keep running into is that the only way for the buttons to actually work is if they are already selected (Or, the last one clicked will work but the other will not). Then the keycode will work for them. How do I make this work without having to click on the button prior.

VS 2008 Bug With E.Keycode On KeyUp Event Handler

Dec 31, 2009

I have this code

If e.KeyCode = Keys.D0 Or e.KeyCode = Keys.D1 Or e.KeyCode = Keys.D2 Or e.KeyCode = Keys.D3 Or e.KeyCode = Keys.D4 Or e.KeyCode = Keys.D5 Or e.KeyCode = Keys.D6 Or e.KeyCode = Keys.D7 Or e.KeyCode = Keys.D8 Or e.KeyCode = Keys.D9 Or e.KeyCode = Keys.Oemplus Then

[Code]....

The output WILL be 189 when I press the - sign. But when I check "Keys.OemMinus" it stands for 189 and when I replace "Keys.OemMinus" with 189 it won't work either!

I checked the Resources file and it's correct. The picture just doesnt change, only shows the last pressed button...
