View 1 RepliesKeypress - How To Use KeyDown Event In Form
Mar 10, 2011I'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.

Forms :: Listbox Horizontal Scroll Event?
Oct 20, 2010So I have a custom listbox that is displaying garbage text when scrolling horizontally. I need the custom listbox to stop an annoying flicker, but it's causing issues with the scroll. I think I could solve the issue if only I could access the hscroll event, but I don't know how to do that. I will put down my custom listbox class just in case you will need it to understand the problem.
Edit: I realized my question is a little vague - telling me how to access the hscroll event within the listbox will suffice

Cell KeyDown Event - The Event Does Not Exist?
May 24, 2010I 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, 2011I 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.
KeyDown Event On Another Window?

View 7 Replies.net - KeyDown Event Firing When No Key Is Pressed?
Aug 20, 2011I 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, 2011I 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.

View 2 RepliesKeyDown Event Not Firing With .NET WinForms?
Oct 22, 2009I 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

View 6 RepliesStop WebBrowser KeyDown Event?
Feb 27, 2011I'm using a webBrowser control as a simple HTML editor & I'm trying to stop the default action of creating a new <p> (paragraph) element every time you hit the enter key while typing text into the control.
I have added a handler for the keyDown event & I can insert a break tag, but nothing I do seems to be able to stop the webBrowser from continuing to process the event.
As you can see in the code I tried setting the e.BubbleEvent to false to stop the event.
The added event handler works just fine & executes before the webBrowser processes the event, but setting the e.BubbleEvent=False (or true) has no effect.[code]...
Textbox KeyDown Event Not Firing?
Apr 19, 2012I have a textbox on a tabcontrol page, and when someone tabs out of the textbox, it is suppose to move to the next tab. This was working great before I switched the form from a UserControl to an actual Form. This change did not change actual code. So now, I have tried everything. I have the textbox to set to AcceptTab = True, and I have KeyPreview = False (because if the form grabs the event before the textbox does, it would mess things up I am assuming).Here is my code for the textbox:
