I have a tabcontrol with 3 tabs. I can't see where any event is raised when I click the small tab area (where the name of the tabpage is). I see where an event is raised when I click on the tabpage itself. What is the event for the small tab area? I am getting by with a mousemove event over the currently selected tabpage.

how to validate and save the results of a textbox when I change to another tab on a tabcontrol?I have found the SelectedIndexChanged and LostFocus but they do not tell what was the tab that has been previously selected, so I then can do that validation and save. is there an event that triggers before the SelectedIndexChanged?

I'm searching for a way to change the font size of selected text in a RichTextBox (rtf) having different font families (e.g. Arial and MS SansSerif) and font styles (underline, bold...) using the FontDialog, but without changing the families and styles. The following code resets all the font attributes, which is not what I want:

I do the above to cancel the menu if S or V is pressed.
I'd like to cancel if ANY key is pressed.

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.

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.

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
End If

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?

I know that you cannot disable Ctrl Alt Del for security reasons. I was able to figure out how to disable ALT+F4 in my application though. What I am wanting to know is if anyone can give me some code to where If CTRL ALT DEL is pressed then my application will close. I have tried everything, and I just cannot seem to get the program to recognize if the user presses ctrl alt delete.
So basically I need some code that detects if a user presses ctrl alt delete then if htye did it closes the application.
(I am making a quiz program.)
PS: I am on Windows 7 RC and I also use Windows Vista. I am using Visual Studio 2008 Professional Edition.

I have a series of textboxes that I need the user to be able to navigate. When the last textbox in the series is filled I want the cursor to go to the first box in the series and have the next row in the datagridview selected. The problem is, for some reason, the tab button being pressed (keyup, keydown, and keypress) is not being detected by the conventional handling of those events. Instead, the tab on that box goes to the next item in the tab index.How would I capture that key or key press event and execute my code?

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
