View 9 RepliesI have a VB 2008 form with about a dozen buttons that use ALT+key shortcuts, e.g. names beginning &S, &N, etc. I also have a menustrip with a couple of entries but I have not assigned shortcut keys to any of them. However, three of the entries on the menustrip begin with S, N, and E. The result is that the shortcut keys for those buttons don't work - instead the shortcut activates the menustrip item. For example, ALT+E brings up the Exit on the menustrip instead of activating the button with the &E... label. I even tried setting the shortcut for the menu item to something totally different, but it doesn't matter.Even though I have programmed something different, the menu strip takes precedence on the shortcut. is there any way to just disable shortcut keys on the menustrip? What I've done for now is alter the names of my menustrip items by numbering them, e.g. "5 Exit" instead of "Exit" so that ALT+5 does the exit and leaves ALT+E for the button I want it to be associated with.
View 3 RepliesI have a group of radio buttons inside a groupbox and I don't want the user to be able to move the focus away from a button by using the arrow keys. I've tried the following keydown event, but it never gets fired:

' If an arrow key is pressed, maintain focus on this radio button
If e.KeyCode = Keys.Left Or e.KeyCode = Keys.Right Or e.KeyCode = Keys.Up Or e.KeyCode = Keys.Down Then

I 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?
View 1 RepliesI had a post about how to disable monitors, but someone suggested just making it not possible to leave the primary screen. This was obviously a good suggestion, but im not sure how i would accomplish this.
I need to prevent the user from entering the ctrl, alt, delete, escape, and windows key. I also need to prevent the mouse from leaving the primary screen.
My program is a security login system. It requires a username and password to close, and i want to make sure that it cannot close unless the user supplies the correct username and password.
I 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
It works, but then if I add a button for example, it stops.
just wondering how i could give my auto typer hot keys, for example they press f1 to start the typer f2 to stop it.

View 4 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 12 RepliesI need to capture the left and right arrow keys in Form1.KeyDown event so I can use them as hot keys. Instead they seem to be assigned to tab order (move focus to previous/next control) and the KeyDown event never gets called. How can I remove the arrow keys from tab order and use them for my hot keys instead?

View 4 RepliesI want to change the "a" and "d" to key controls left and right perspectively. and I am having some trouble wiht the key up event. KeyChar works for KeyDown (after I forced it to) but not for KeyUp (even though they share the same things). I finally figured out how to get the picturebox to change its picture, but now I am stuck at this part. getting an animation in, and when im done moving, get the animation back to the idle picture. im also having a little bit of trouble with movement. pictre - as a split second of movement and (space) as a split second of not moving, when i begin moving, lets say it goes this way (there is a space right after the first -, so that was a split second that it stopped and then started continuously started moving again). how can i make it so it goes nice and fluid once you start moving? also, if i were to press any single key while holding A or D down, it either stops and i have to press the key again to move it move or, it goes in the other direction(if I hit a then d, or d then a). and in the key up event, id like it so when the a (or d) key is up, it goes back to the stand animation, and when moving, it goes to the moving animation.

I have an image viewer application which consists of a Panel with a picture box on it. I want to use the arrow keys to iterate through the images in a folder. I have programed other keyboard shortcuts and all of them work except for the arrow keys, my program does not even acknowledge the KeyDown or KeyPress Event with the arrow keys. [code] As I said, all key events will fire the KeyDown with exception of the arrow keys.I have tried the Keypress event also and had the same problem
