View 9 RepliesHow To Disable Menustrip Shortcut Keys
Jul 16, 2009I 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.

Disable Ctrl Keys And Print Screen In Web Browser Control?
Apr 16, 2009I 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 RepliesRestrict Mouse Movement To Primary Screen And How To Disable Keys
Oct 5, 2009I 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.

C# - Mdi Children Changed In .Net?
Apr 15, 2010Is there a simple way of tracking the change of an Mdi's children i.e. when they are created and closed, something like an event OnMdiChildListChanged (I realise this doesn't actually exist).
I am also aware that I could have a method within my Mdi that handles the creation of child forms and logs the state of them or even create an Interface that defines that a child form has a "NotifyParent" method that is then called on close of the form, but i was wondering if there was any built in events that i could plumb into?

View 3 RepliesMDI Parent And Children
Jun 3, 2011I have four children in a parent container. Each child form is a test for the user to type correct answers into text boxes. Option to open each form is on a menu strip in the parent. In form load, I have disabled all but the first form option. I only want the second form to become available if the first form answers are correct. I would like to figure this out on my own as much as possible. I have searched on line but since I am not sure what to ask, I have not found and answer. Can someone get me started in the right direction? Perhaps some reading that would explain how to go about this, or what I should be typing into google to get what I'm looking for.

Not Loading All Children XML
May 6, 2012[code]...
I'm sifting through the dump of AniDB titles and everything works except that it only sees 7161 elements instead of 9200. Anyone have any idea why? It's not calling an exception on the load method as if something is wrong. Even when I change it to just take the root element and then get the count of children, it gives 7161. Like it doesn't even see the last 2000.

View 4 RepliesRecored Arrow Keys And Then Tell Computer To Enter Arrow Keys?
May 23, 2010So 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 RepliesChanging Focus Between MDI Children
Jun 3, 2011A common problem I have come across when migrating from VB6 to VB.NET is that to change the focus between MDI children, you can't just click any control to give that child focus, you must click its title bar. The solution that I have found works is to enter the child form's Designer and change the following:
Code:
#Region "Windows Form Designer generated code "
<System.Diagnostics.DebuggerNonUserCode()> Public Sub New()
MyBase.New()
'This is required by the Windows Form Designer.
InitializeComponent()
[Code] .....
This needs to be done on all child forms in the project. If one form does not have the fix, once it's opened, the bug will return even when the form is closed.
