How to setup a a "Global" shortcut in vb.net application?

1 New Member
I am writing an application for a customer and one of the late requirements is for a (ideally) configurable key stroke to display a form. This should operate no matter which form/ dialog is currently displayed. Firstly is this possible and secondly how do I do it without adding the same code to every single form and dialog box which now number about 40 and growing.

Windows 7, vs 2010, vb.net, infragistics controls.

Thanks in advance for any help.

Here's the code from the above URL...

Expand|Select|Wrap|Line Numbers
  1. Private Declare Function GetAsyncKeyState Lib "User32" _
  2.    (ByVal vKey As KeyCodeConstants) As Long
  3.  
Expand|Select|Wrap|Line Numbers
  1. Private Function KeyDown(ByVal vKey As KeyCodeConstants) _
  2.     As Boolean
  3.    KeyDown = GetAsyncKeyState(vKey) And &H8000
  4. End Function
  5.  
  6. 'DEMO USAGE
  7. Private Sub Timer1_Timer()
  8.    If KeyDown(vbKeyF10) Then MsgBox "You pressed F10!" 'This msgbox will appear regardless of the active app.
  9. End Sub
  10.  
I'm not entirely sure how this works - but it's worth a try. As for the Win32 API you really should PInvoke it properly - not like the code snippet above.

I have an array/hash that stores path information for my app. As in, what directory this is in, what directory that's in, what the name of the site is, what the products are called, etc. It's called $glb. So, every function so far looks like this: function something() { global $glb; }

Hi and Season's Greetings to all. I have a question regarding the use of a qualifier word "Global". I cannot find any reference to this in Access help, nor in books or on the Internet. "Global" seems to be recognised by Access in at least three cases:- 1) "Global Const". Recently someone in this group helped me resolve a problem, and it involved the use of a Global Const. By Googling "Global Const", I got plenty of hits -- but they...

I saw in a recent post the :: operator used to reach the global namespace, as in global::MyNamespace I hadn't seen this before, so looked it up in MSDN, which explained it nicely. My question is, do "global" and "::" always go together? Is there any other use for these operators, than as a pair? TIA,

Hello all, I might be missing something here, but am trying to understand the difference between using application-level variables--i.e. Application("MyVar")--and global variables--i.e. public myVar as string, etc. It seems to me that the scope and duration are the same, as they both are there while the application is running, and both go away when it quits. I presume that one difference is that the application state can be "flushed," such...

Hello, In an aspx page (mypage.aspx) from a web projet, I would like to get the value of a variable of the projet that is declared as public in a module. The variable can be called from anywhere in the code behind page and in the class files, but when I try to call it from an aspx page, it raises an error. <%=myvar%> in mypage.aspx raise an error : the name "myvar" is not declared.

If I have a class that hold, for instance, user settings that should be accessible to the entire program logic, what is a good paradigm to use? In C++, I would have made it a global object, protected if necessary for thread safety. In C#, of course, there are no global objects. The Program object is static, so cannot contain object instances. While I could store it in my main form pass it around, that seems cumbersome. I could do a...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
