System-wide Hotkey

This code lets you use hotkeys from your program. Even if your app is not in focus the hotkey will work. This one is CTRL + A
Also to change the Keys you will probably need the Virtual Key codes
They Are Here

VB.NET Code:

Private Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Integer
    Private Declare Function UnregisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer) As Integer
 
    Private Const WM_HOTKEY As Integer = &H312
 
    Private Const MOD_ALT As Integer = &H1
    Private Const MOD_CONTROL As Integer = &H2
    Private Const MOD_SHIFT As Integer = &H4
 
    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        UnregisterHotKey(Me.Handle, 0)
    End Sub
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        RegisterHotKey(Me.Handle, 0, MOD_CONTROL, Asc("A"))
    End Sub
 
    Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
 
        If m.Msg = WM_HOTKEY Then
           If m.WParam = 0 Then
            'CODE HERE
           End if
        End If
        MyBase.WndProc(m)
 
    End Sub

I really dont want to seem like I'm just hating on all your codebank posts and I dont want to discourage you from posting things in here, but... there are already a few threads in here that show how to do this - just do a search in the codebank before posting something here as there is no point duplicating things really. I just searched for "hotkey" and found this thread which has a nice managed .NET class that wraps up the functionality of the APIs you mentioned: http://www.vbforums.com/showthread.php?t=542976

PS using Ctrl+A as a system wide hotkey is a bad idea as loads of programs use that for selecting all text. I'm sure you were only using it as an example though.

I'm also not wanting to seem like I'm hating Emcrank's codebank threads, but most of them are basically just copies of other codebank threads, some of which have been on the forum for years already.

Like the move borderless form thread, it's identical (even the flaws of moving a borderless form that way) to the other one that was mentioned in Emcrank's codebank thread.
