Determine If Any Keyboard Key Is Pressed?

Mar 3, 2012

I have a few problems with my VB.NET project. I am making an application that should track every key inputted by the user. This may sound scarily like a keylogger, but it is intended for statistics purpose only. All data is stored on the client's computer and will not be sent anywhere on a network or the Internet.

The problem is actually figuring whether or not a key is pressed globally. That means, not in a KeyDown, KeyUp or KeyPress event. Let's say if the user inputs anything in Microsoft Word, my application will notice.

I have already tried this code. It gives PInvokeStackImbalance errors in the MDA. It has actually worked out for another application I am making, until I figured the severity of this error.

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer
Private Sub CAKS(ByVal Key As Long)
Dim WasBeingHeld As Boolean = False

[Code]....

Get A Key Pressed From The Keyboard?

Nov 7, 2010

This may sound like a dumb question but I need to know. I know you can tell which keys are pressed on the keyboard but I like to know if I can do something.Ok, heres what I am trying to do. A user is in another program that is max on the screen. He has to press Print Screen to take a screenshot, but he got to min the screen he is in to paste the screenshot into paint. This causes slow loads on maxing that screen and sometimes crashs of the program. I already got the code done to check when the program is running and to capture the screenshot and save it. What I to do now is, find out while in the other program with my program running in the background, if the user has pushed the Print Screen button.

Simulate A Key Being Pressed Or Held Down On The Keyboard?

Feb 2, 2010

I know how to send keys using Sendkeys.Send("{RIGHT}") I even know how to use Send keys In a timer, to repeat the key press... But it's just a key press, and it lets the key up. So If I tried to put sendkeys.send("{RIGHT}") under a Timer, then it will press/release the Right Key. I don't want that. I want to HOLD THE KEY DOWN. Here's Some Code, that I know how to do that Simulates a Mouse Click, Left Down, AND Left Up. Mouse Click. Ok...? So here's some example code of how to Send a simulated Mouse Click.

EXTREMELY EASY, BUT EXTREMELY POWERFUL CODE. Simulated Mouse Clicking.

Check If A Key Is Currently Pressed?

Feb 4, 2010

How would I check if a key is currently being pressed?

Also how would I detect if a key is pressed without using the KeyDown event. The reason I am not using the keydown event is when the user holds down a key it calls the event, waits a second than keeps calling it. I do not want the wait period if a user is holding down a key.

Asp.net - Detect F5 Being Pressed And Refresh?

May 25, 2009

I have a webform and i want to detect if F5 button was pressed or if the page was refreshed. I know about postback but it is not what i'm looking for. I have a gridview that loads in a modal popup when a button is clicked and a parameter's value is set for the gridview. When refresh is hit and if the modal popup button was previously clicked the modal popup is visible right after refresh. I want to detect if the page is refreshed to prevent this. any ideas? I thought to try Override but I'm not exactly sure how to use it. I tried Control.ModifierKeys but I don't have access to ModifierKeys.

Im doing a small project in visual basic which involves lighting up leds through the parallel port and turning them on and of. each led is controlled by a checkbox on my form and they only come on when the checkbox is checked.

what code do i need to use to have the checkbox checked when a key is pressed but when the key is released the checkbox is unchecked i have already tried keydown which will check the box when a key is pressed but will not uncheck it when the key is released

If e.KeyValue = Keys.A Then
CheckPin1.CheckState = CheckState.Checked
ElseIf e.KeyValue <> Keys.A Then
CheckPin1.CheckState = CheckState.Unchecked

Continue A Program Unless A Key Is Pressed?

Nov 8, 2011

I am making a Tetris program and I have a 2d array 10 by 20 for the grid.I want the Tetris blocks I have created to move down one block every second unless the user presses "a" or "d" (to move left or right) then the block should move left or right whilst moving down.The problem is that I have created a loop for it to delay a bit but then it waits for the user to press a key until it continues the program. So the block will stop moving down and just stay where it is until they press something.I have been told that you can do this in C with something like if keyboardhit or kybd() or something then it will read the key but otherwise it will just skip that bit and loop round. So how can I do this in VB?
