View 6 RepliesI 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.

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
[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 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...
A program cant be exited thu Alt+F4
[Code]...
Edit2: I want it to be in the form so that the form cant be closed unless they press button with Close() command or task manager ends the process

The problem is that when you press F1 - F4 or F9 nothing happens, am i using this code wrong? I have the code under the Form1_KeyUp section of the code.
So I opened 2 forms, Form2.vb and Form3.vbNow I put this:
Private Sub Form1_PreviewKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles Me.PreviewKeyDown
If e.KeyCode = Keys.F8 Then

My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .
View 2 RepliesHow would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

View 2 RepliesI'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:
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:

If I have the code:Dim x as Decimal = 100.0m
Is it casting from a double to a decimal implicitly. How would I do this explicitly in vb.net?
1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:
Variable 123.34D ----> textBox 123,34 or 123.34 -----> variable 123.34D
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?

whats the simplest way to achieve this? is there a built in value for this or regular expressions?
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]
