VS 2010 Get Key Name From KeyEventArgs.KeyCode
Aug 1, 2011
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.

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.

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:

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.

I wrote this:
Private Sub TextBox2_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox2.KeyDown
If e.KeyCode = Keys.Tab Then
MsgBox("Tab")
End If
End Sub
Why it doesn't work when I press tab on my keyboard?

I want to use e.KeyCode while form is minimized, I'm working on a screenshot-taker if you know what I mean. So Form1 is minimized > User presses F9 (Let's say the key is F9) > An event happens.

Does anyone know the global keycode for the windows key? I know that alt =1, control =2, and shift = 4. Also if you know the answer can you tell me where I can find the global keycodes?

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.

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?

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...

Private Declare Sub Keyboard_Event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) [Code] I know the KeyCode when i call this function. Example 13 is the keycode for "Enter". But it says that theres an error on syntax cause KeyCode is an integer not Byte. What kind of variable does it need there? I mean does it need the keycode (which is a number) or a character e.g. "a"? [Code]

Is there an easy way to get the corresponding keydata (keycode combination) for some value in that enum? I cannot find one, and creating a switch statement for all those is a bit overkill...The integer values of the enum elements are not keycodes, but some 'unknown' big numbers, so simply casting to int won't work.

I have various input textboxes on my form. And based on entries made in each of the input textboxes, I update the display textbox. However, using AppendText message of textbox. I have my input textboxes set to accept only numeric values. So for each character inputted correctly, I update the display Textbox. Problem I have is when user selects Key.Back or Key.Delete, what I would like to do is do a Delete of last character in the display textbox, but I am yet to get this right. How do I delete the last character in the string that is contained in a TextBox using AppendText()

I need to be able to send keycode keys.apps (windows context menu key) to an application. Surely if I can detect the keypress, there's a way to send the keypress, right?
What I'm doing is having a 3rd party app save a screenshot and the only way to have it do so is through its right click context menu.
