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?
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 using the keydown event so that when i press the right arrow the image changes but when i run it nothing happens when i press the arrow key.I have enabled the keypreview Properties?
Private Sub Level1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown If tmrWalk.Enabled = True Then Else If e.KeyCode = Windows.Forms.Keys.Right 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?
I 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.
I 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.
I 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.
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.
When I put the command in the form_keyDown event that if I pressed the Ctrl+s, run the some instruction, when the focus in the one textbox control, run one beep sound Simultaneously with the instruction.
Is it possible to set focus on the keydown event so after the button control, sets the focus into the keydown? although says often control can have focus,.Putting a button and a keydown event on a form...
when I added a textbox to my form, my keydown events no longer work. It seems impossible to get the blinking cursor out of the textbox so as to avoid targeting it. How do I retain keydown events when a textbox is added to the form?
I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.
I am getting some wierd behavior in VS2008. I have the following code in 2 different forms in the same project. One form pops up the help as you would expect when you click the Help button, while the other form does absolutely ntohing when the Help button is clicked.[code]
suppose i have two forms form1 and form2 and i clicked on button which lead me to the form2..i want i shouldn't be able click on form1 untill and unless i close the existing form window(i.e form2)
I have win7 pro, on my win form is a traffic light icon(when it starts it is red, when finished it is green), so that I know when job is finished. But when I run application icon isn't changing and form hangs it self, can not do nothing until job is finished. Only in the end, I see that icon is quickly changes to red and then back to green.
I 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.
Now I am calling mainform from WindowsStartForm-> SetupStartForm.vb file. This is the code
[Code]....
I have the problem is that in the messagebox it shows the incremented value. But no updations are there in the textbox of mainform. What is the reason for that.
I tried searching and found out that someone has written a multipart form uploader. Though it had one thing wrong: It transfered all the - supposedly - POST values in the url.. Which the web application doesn't like - somehow.
-> When i open the windows form, if i press ctrl + Enter, then pop windows is opening
-> if i enter any data's in the text box, then i press ctrl + Enter, then pop windows is not opening
Code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.KeyPreview = True End Sub
[Code]....
When the form load, ctrl + Enter shortcut key is working, once i enter or select any data's in the form, then ctrl + Enter shortcut key is not working (not showing the popup windows)
