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.
CODE:
Is there any built in way to get the key name from the decimal alt codes returned by KeyEventArgs.KeyCode? e.g. get "Space" from 32 If not I guess I'll have to create a huge array.
View 5 RepliesI'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:

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.
For example this textbox here: url...without clicking and selecting it. Just use a key ex: F5 to paste the text i copied to this any textbox or shoutbox?

If e.KeyCode = Keys.F8 Then

I am creating a setup project for my VB application. Everything seems to look fine. However when I tell it to build the solution I get the following error:Property 'keycode' is non-nullable. I have never seen this before in other setup projects and I can't find any help from MS.

View 2 RepliesI'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

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.
I tried to build my project but it has 1 build error
:Property 'Keycode' is non-nullable.
I double click it but it points nowhere. I'm really desperate. My project consists of Crystal Report. It had just been upgraded from version 8.5 to version 11. Is it possible that this is the source of error?
[Code]....
whats the simplest way to achieve this? is there a built in value for this or regular expressions?
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...
possible to register 2 hotkeys? If so h
