I have a problem in my form I am trying to stop my form from being submitted or closed
I have 2 buttons accept btn and cancel btn whenever the user pres enter or ESC the form is closing I tried everything from key press to key down and nothing works,
So 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 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.

I 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

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 RepliesIs there a way to prevent the Enter key from being interpreted as a button click.
I am trapping key strokes at the form level but if a button has the focus and the ENTER key is pressed I cannot trap the enter because the button consumes it as a button click event. I am also unable to trap the enter key in any of the button's key events.
I am interfacing with magtripe swipe and barcode readers that send their information as keystrokes with a CRLF at the end. I have a work around by chaning the focus to a textbox anytime keystrokes are detected but I am hoping for better control.

View 3 RepliesWhen editing C# code in Visual Studio 2010, the ENTER key makes IntelliSense complete the current suggestion, without adding a new line. In VB.NET, the default IntelliSense behavior for the ENTER key is to add a new line after completing the current suggestion.

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..
