VS 2008 KeyDown Or KeyPress?
Aug 31, 2011I'm currently experimenting with a tile based dungeon crawler type game. When the WASD keys are pressed it will move in that direction, however if the key is held down it will move incredibly fast over the tiles, which is not what I want.Instead I want the player only to be able to move one tile at a time, or after each key press. Is there any way to do this with the KeyDown event or do I have to use KeyPress to make sure it only activates after each full key down & up?

VS 2008 Datagridview Display With Keypress Event
May 6, 2010I have a datagridview bound to an Access datatable. It is nothing more than a one column list of chemicals. To allow the user to more easily navigate the list, if they press a letter it will jump to the first chemical alphabetically of that letter. If they keep tapping that same letter it will move down that list one by one. This all works fine. The problem is if you hold down the letter it will progress down the list but it doesn't show that progression. I want it to function much like if you hold down the down arrow key in a datable you'll see each successive cell be selected as it goes down the column.

VS 2008 KeyPress Handler - Doesn't Remove All Handlers
Jun 16, 2009to know if a control have any handler. I have a dgv and in the editing control Showing event i add an event handler like this: VB AddHandler e.Control.KeyPress, AddressOf Grid_KeyPress_NumbersOnly This event it's added in some of the columns and for the other ones i remove it... The problem it's when the user, for example selects 3 columns where the event it's added, then if the user selects one where the event it's removed, it doesn't remove all handlers... So i have 2 solutions, when removing i put multiple removes or the other check if the event handler it's added doesn't add again. I prefer this second option, but i don't know how to check if the event it's added?

How To Track A Certain Keypress
Mar 24, 2012Before anyone tries to close this thread thinking this is for malicous purposes, let me tell you that it's not. What i'm working on is an application to save screenshots to files as soon as the 'Print Screen' key is pressed, as Jpegs or what ever. What i want to do is be able to minimize the application and I still want the application pick up on any 'Print Screen' presses, and save the screenshots. I've tried using the KeyPress event, but I soon realized that it only worked when the application had focus. I plan on using it to save screenshots every time I press 'Print Screen'

Capturing And Using Keypress Events
Apr 30, 2010I am trying to modifying the "Math Quiz" tutorial to be more user friendly.
The initial tutorial does not consider the users efforts to answer the math problems as quickly as possible.
The problem is that you must use the mouse or tab key rather than the "enter" key to move to the next control after answering. I believe using the "Enter key to be much more intuitive.
Therefore, I wish to modify the program to either:
1. Check the KeyPress event of the NumberUpDown controls to watch for the "Enter" key to be pressed, and if it is, check to ensure that the current NumberUpDown control is not empty (= Nothing) and if both are True, to then TAB to the next control in the TAB order; OR
2. Uses the PreviewKeyDown event to transpose the "Enter" into a "Tab" automatically so the application will then TAB to the next control in the TAB order.
With all of the new changes to VB 2010 from the last version I actually used professionally (VB6), things are REALLY different, so I no longer know how to accomplish this same task in the new manner. especially if it contains working CODE, because I have always learned better the first time from an example. here is my version of the tutorial Code:
'--- Create a Random object to generate random numbers.
Private objRandomValue As New Random
'--- The Integers will store the numbers for the
' addition problem.

View 1 RepliesDo Until KeyPress In Console Application?
Mar 9, 2011I have a console application and i want to run some code but at the same time I want to have the ability at any given time to press CTRL + SHIFT + S to stop it,
Now I tried doing something basic like this which would stop if you press X at any given time:
Dim stTest as string
Do Until stTest = "X"
stTest = console.ReadLine
console.WriteLine("you didn't press X yet...")
The problem is that every time before it writes that line it will wait for the user input because i have "Console.ReadLine" on there, I don't want that to happen, I want it to keep going until a set of keys are pressed.

Keypress (not Send) Event?
Jun 2, 2010I couldn't manage what the matter is not even after searching. Here my question goes:I need to do a simple task (close my form on pressing escape key) and I use the following code:
Code:
Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
Select Case (e.KeyData)
'Close on Escape
Well , it works when I click escape my form closes , but.. if I have pressed by accident or some else matter any of the arrow keys (up , down , left , right) before escape and then hit escape nothing happens. I checked if any other key does that and as I see it does not.
