I have a TextBox and set the MiltiLine property to true and AcceptsTab property to false.When the TextBox has focus and i press Tab it works fine and the next control get the focus, but when i press Ctrl+Tab it works as if AcceptsTab property is set to true and makes a tab character into the TextBox.The reason i press Ctrl+Tab.. when switching between forms in my MDI application.Now how to make a Ctrl+Tab when pressed works like Tab when pressed in a MultiLine TextBox?
View 1 RepliesI 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.

However, as soon as the user presses CTRL-ALT-DEL the Windows Security Screen comes up and it is too fast for VB to detect that the keys have been pressed.I did a little reaserch on how to work around this issue and found that a GINA stub can be written which can delay the Windows Security Screen by some time say 2 secs which would be enough for VB to detect that the keys have been pressed.Also disabling Ctrl-Alt-Del through VB does not work because it is too fast for VB and I would like not to disable CTRL-ALT-DEL
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.

View 6 RepliesI'm making a system where only the supervisors can use the Ctrl+Alt+Del to bring up the menu (Vista / Windows 7) or start taskmanager (XP)Since my application will not be running on anything less than XP I don't need to worry about 95, 98, ME, 2000, etc. I have this code so far (found on here and a little edit by me) but the Ctrl + Alt + Del doesn't get stopped like I thought it would.
