How To Disable Menustrip Shortcut Keys

Jul 16, 2009

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.

Forms :: Windows Beeps When Key Combination Entered

Jul 30, 2011

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]

Disable Ctrl Keys And Print Screen In Web Browser Control?

Apr 16, 2009

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?

Restrict Mouse Movement To Primary Screen And How To Disable Keys

Oct 5, 2009

I 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.

Remote Windows Registry Keys?

Dec 28, 2009

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 ?

.net - Accessing Private Keys From Certificate Deployed To Windows Azure?

Nov 17, 2011

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.

Function Keys Stop Working While Using Windows Media Player

Sep 29, 2011

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.
