Hi
It is preferrable to get a solution using VB.NET but C# is acceptable as I can always convert it ti VB.NET.
I am creating a "custom toolbar"with pre-programmed keyboard key combinations for a disabled person. The user first starts the "toolbar" and then starts any application with the "toolbar" displayed on the screen. I do not know the process name or PID of the user application. The user clicks a toolbar button and the appropriate key combination is sent to the user application. I have tried to use SendKeys and keybd_event and nothing works.
I have read that I must have a handle to the active window. All the examples I have read seem to require I know the proceess name to get the window handle. How do I do this if I do not know what process was started?
I have tried:
And
I am missing something and I am not sure what. I am fairly new to VB.NET.
Also is it better to use SendKeys or keybd_event?
Thanks in advance for any help

I have tried:
Code:
Public Shared Sub btnSend_Click(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles btnSend.Click
Dim TopMosthWnd As IntPtr
Dim OldActivehWnd As IntPtr
Dim NewActivehWnd As IntPtr
TopMosthWnd = GetWindow(Me.Handle, GW_OWNER)
TopMosthWnd = GetWindow(TopMosthWnd, GW_HWNDFIRST)
OldActivehWnd = SetActiveWindow(TopMosthWnd)
NewActivehWnd = GetActiveWindow()
SendKeys.SendWait("%f")
End SubCode:
Public Shared Sub AltPlusAlphaNumeric(ByVal Value As String)
keybd_event(VK_MENU, _
MapVirtualKey(VK_MENU, 0),
0, 0) ' Press Alt
keybd_event(&H46, _
MapVirtualKey(&H46, 0), _
0, 0) ' Press Key
keybd_event(&H46, _
MapVirtualKey(&H46, 0), _
KEYEVENTF_KEYUP, 0) ' Release Key
keybd_event(VK_MENU, _
MapVirtualKey(VK_MENU, 0), _
KEYEVENTF_KEYUP, 0) ' Release Alt
End SubAlso is it better to use SendKeys or keybd_event?
