Keypress - How To Use KeyDown Event In Form

Mar 10, 2011

I'm using VB.NET (2008) and .NET framework 3.5. In my application I've got an on screen button that, when pressed, sends "00" as the characters [via SendKeys.Send("00")]. I also have a keyboard that has a '00' key that sends "00", two zeros, when pressed. I'm picking up the keypress using the form's KeyDown event - it fires twice, once for each "0" and works whether the on-screen or keyboard '00' is pressed. There's also a singe '0' on-screen button and key on the keyboard that sends "0".

I want to be able to treat the "00" as a single event. I.E. in the KeyDown handler, if the character is a single zero "0", I would like to check the next character to see if it is also a zero "0". If it is then I can handle it appropriately, but also need to remove it (from the keyboard buffer?) so that it doesn't fire the second KeyDown event. If it's not a zero then it should be left to fire the next event in the normal fashion.

VS 2008 KeyDown Or KeyPress?

Aug 31, 2011

I'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?

KeyDown And KeyPress Events Not Responding

Mar 7, 2009

In the application I'm working on I use F1 and also a right mouse click to close the application since the graphics display full screen and there's no control in the upper right corner to close with. I use a good number of different keypresses to control things and everything works fine. When I switch away from the form that the applications starts in to a different form I'm not getting any response from either a KeyDown or a KeyPress event. Maybe someone knows what's going on. The ButtonClick and MouseDown events are responding just fine but for some reason the KeyDown and KeyPress events aren't. Below is code for one of the Forms that is unresponsive in this way.

IDE :: Using KeyDown And KeyPress Events On The Same TextBox Control

Jun 4, 2009

I have a TextBox which Is allowed only to read certain characters. I use KeyPress event to handle this event. I understand that The KeyPress event does not handle the pressing of the DELETE key on the keyboard. I do not want the user to be able to delete characters in the txtbox by using the DELETE key, I want the user only to be able to use the backspace key. I am writing this code in Visual Basic 2005. The following code appears to work in handling the DELETE key, but I am concerned that I might get bitten by the fact that I am using KeyDown and KeyPress on the same control (txtSource).

private sub txtSource_KeyDown(byval sender as object, byval e as KeyEventArgs) handles txtSource.KeyDown
IF e.KeyData = System.Windows.Forms.Keys.Delete then
e.handled=true
end if
end sub

Looked up a number of pages on KeyDown, and KeyPress events, and am just more confused than when I started. I am trying to get an event to fire adding value to a total when a user presses the Enter key. Not getting any compiler errors, and have tried utilizina MSDN's suggestions for IsInput, and PreviewKeydown. None are working..... I have tried working in the KeyDown using e.keyCode = Keys.Enter, and KeyPress using e.keyChar.Equals(Keys.Enter) in my conditionals.

Cell KeyDown Event - The Event Does Not Exist?

May 24, 2010

I have this code in the onKeyDown event of the datagridview.

Private Sub DataGridView1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
Select Case e.KeyCode[code]....

This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.

KeyDown Event Not Working?

May 11, 2011

I have checked my code countless times, tried other computers, and yet the keydown event will not work.

My code:Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

If KeyCode = vbKeyRight Then
imgPerson.Left = imgPerson.Left + 500
End If
End Sub

That's all there is because I was just testing it out. imgPerson does exist, so that's not a problem.

.net - KeyDown Event Firing When No Key Is Pressed?

Aug 20, 2011

I am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:

Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)

When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".

How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.

Cursor Changes When Keydown Event Is True

Nov 15, 2011

I need to make a simple yet cool program for my professor. The program is this: To get the program to work, the user first presses a button on the form. Then, when the user presses an up arrow on the keyboard, the cursor will change to a custom cursor (a cursor with an image of car {in .ico format} for example), when the user releases the up arrow key, the cursor turns back to default cursor -- which is arrow. When the user presses an up arrow and left arrow at the same time on the keyboard, then a different custom cursor will be shown instead of the default.

KeyDown Event Not Firing With .NET WinForms?

Oct 22, 2009

I already have KeyPreview set to true in the form properties I'm working on a small program, and I'm having a problem where it seems that some of the controls on it inside groupboxes are not triggering the KeyDown event on my form when I press and release any arrow key, just the KeyUp event. Specifically, I've enabled KeyPreview on the form, and set breakpoints on e.SuppressKeyPress = True in both subroutines, and only the one for frmMain_KeyUp hits the breakpoint.

I added in the two GroupBox events hoping that might mitigate the issue, but no such luck. However, I have a custom control on the form that is specifically coded to ignore these keypresses, and the code works as expected on it.

Private Sub frmMain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown, GroupBox1.KeyDown, GroupBox2.KeyDown
e.SuppressKeyPress = True
Select Case e.KeyCode

[code]....

The code in the user control that "ignores" keypresses is as such:

Private Sub TileDropDown_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyValue = 40 OrElse e.KeyValue = 38 OrElse e.KeyValue = 39 OrElse e.KeyValue = 37 Then
e.SuppressKeyPress = True
End If
End Sub
