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...

C# - Convert System.Windows.Forms.Shortcut Into KeyData / KeyCode?

Nov 15, 2011

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.

Send Keycode Keys.apps (windows Context Menu Key) To An Application?

.net - Equivalent Of VB And And Or In C#?

Oct 14, 2010

I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic's And and Or in C#?For example, consider the following VB.NET code.The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic's And operator is perfect for this situation, but unfortunately there's no equivalent operator in C# as far as I know (&& short-circuits).
