Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.Control Then
MessageBox.Show("aaaa")
End If
End Sub
As you can see, my form will check for when the control key is pressed down.But it doesn't work. Why?
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.
Well I'm currently in the middle of adding a few fine details to a program I'm busy with. Basically whats happening though is that I want to be able to delete some settings on the fly instead of individually, I also want to accomplish this through a simple key press.
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.F1 Then
MsgBox("Do you wish to remove all entries and clear all relative data?", MsgBoxStyle.YesNoCancel)
If MsgBoxResult.Yes Then

I am trying to use the keydown/keyup events with buttons in the same project and it not working properly. I have 4 red boxes and when I press an arrow key the box should change to green according to which arrow key it corrosponds to. I have this part working fine, however only when there is nothing else in the project. When I add in say 3 buttons, Button1, Button2, Button3 and try runing the program instead of the correct red box changing to green, button outline just moves between buttons 1,2 and 3. I have tried turning tabstop off for the three buttons but that didnt work. how to read the keydown/keyup while still having buttions that can be pressed with a mouse?
View 4 RepliesI need to detect shift + arrow key in blank form. But it's not working. I also tried overriding IsInputKey method but it only detects single key press (like arrow key) but when multiple key are pressed it simply doesn't work.
View 5 RepliesI want to know how to do a keydown at form level. If I am not using Form Level the right way, this is what I mean. In my Form there is nothing.I want it so when the user presses a key that it will msgbox() something.As I said, there is nothing on the form what so ever No ComboBox, Button, nothing.

I am having trouble using keydown for the spacebar in a form.I would like the spacebar to start/stop a StopWatch that I have running. I can get that to work fine but whenever I am focused on another button it also executes that buttons function also.I know that is the default behavior for the enter key and spacebar but I would like to override that.
View 5 RepliesI want to able to hold a key down while the application is loading and depending on which is being held down a certain form is shown.
For example holding down shift and the opening itunes opens a little dialog allowing you set the library(or something)
I can check whether the shift/Ctrl/Alt are being held down but i'd prefer to use the letters/digits.
Such as hold 1 down to open Form1 and hold 2 down to open form 2.
In my program I've used a text box and KeyPreview is True.When press the Enter-key i hope go to next row but called the default key?

View 1 RepliesI'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.
I am trying to catch key board events with the form keydown.
I am able to capture all the keydown events except the "Enter" key. When the enter key is pressed this code does not even fire.

View 1 RepliesI have a form that displays a graph. From the appropriate toobar button click frmGraph.show is called and it works. But when I call it from the assigned F6 function key the graph hardly ever displays. Sometimes it does display properly, sometime it flickers a one time display of the graph then it's gone, but mostly the form just draws the background but no graph. In debugging this i discoverd that putting a message box just before the call to frmGraph.show the graph will display properly everytime after i click ok in the messagebox. Anyone know how to cure this or at least a workaround that doesn't involve displaying the messagebox? This is the code with the messagebox("here") just above the call.
