View 1 RepliesCapturing ctrl keys in form KeyDown event
View 8 RepliesI have created my own web browser by dragging the web browser control into a form using Visual Basic 2008 in order to host my ASP.Net pages. However, it is a requirement of the project I am working that users should not be able to use hot keys, especially print screen, ctrl P, ctrl C, and ctrl V. There are no other controls on my form, so how can stop users using these keys, but only in this browser? Further, my asp.net page uses an iframe tag to show a word document, and again, I need to stop them from copying and pasting from the word document into another word document through the browser. Can I stop them in my browser in app stack?

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

View 3 RepliesI have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode

View 6 RepliesSo I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.

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.
Note to use this from within Visual Studio you might have to untick the box for "Enable the Visual Studio hosting proccess". In VS 2010 it is found in Solution Explorer > My Project > Debug > Enable Debugers > Enable the Visual Studio hosting proccess I've found several ways to stop taskmanager loading but not to stop the menu being displayed.
