I 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 1 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:
Private Sub rbCode_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles rbCode.KeyDown
' 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 am working on a program in which I allow the user to quickly add strings to a textbox by pressing a key combination, such as ALT+S. Inserting the strings and setting the cursor to the right position works fine. Its just that windows makes an annoying beep as if an error was encountered every time I press the key combination. I am using the KeyDown event to handle the keystrokes, and I have tried e.Handled = True - without success. Here's a bit of code to give you the idea:[code]
View 2 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?
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 am working on a program that needs to fetch remote windows pc's particular registry keys and then be able to modify them (for example the Run registry key). From what I have been reading I would need to use the OpenRemoteBaseKey to do so.
What I am not sure about is how do I have the program search the network for all of the Windows computers and generate a checklist when the computer names and IP addresses are not known ?
also for the OpenRemoteBaseKey to work do I have to know the password for the administrator account for each PC ?
I want to use System.Windows.Forms.Keys with a variable for example
shortcutkey = "A"
keydata = System.Windows.Forms.Keys.shortcutkey
The idea was to implement custom shortcuts that the user specifies to perform certain actions.
My code is like this
If (((BindingFunctions.IsKeyDown(Keys.ControlKey) AndAlso BindingFunctions.IsKeyDown(Keys.ShiftKey)) AndAlso BindingFunctions.IsKeyDown(keyData)) AndAlso (keyData = Keys.L)) Then

I am trying to access the private key of a certificate I uploded to Windows azure do do decryption. I used a code similar to this post: Using DotNetOpenAuth OAuth 2 with Azure - Reading Certificate - difficulty extracting keys. Andrew Arnott provided an answer to what post referencing this link:[URL].. However I cannot access it so I am not sure what is the solution.
Essentially when try to cast the private key of a certificate as a RSACryptoProvider. I get nothing:
Dim provider As RSACryptoServiceProvider = DirectCast(certificate.PrivateKey, RSACryptoServiceProvider)
That is provider is assigned nothing. The code works perfectly outside of Azure.
I am developing a vb.net media application using Windows Media Player which is working fairly well. However, I am having problems where the Function key handler will stop working after doing anything on the media control panel, i.e. mute, move the slider etc. So long as I don't touch the panel everything continues to work. I'm using the function keys to pull up menus for selecting other media and if I do anything with the control panel I can no longer display the menus.
