I have a screen print utility that resides in memory, that has a hot key
assigned (currently Cntl+Shift+S) that when pressed, captures the active
window and either prints it, saves it to a bitmap file or stores it on the
clipboard as a bitmap.  Would anyone know the procedure to configure a
command button on a Visual Basic form to simulate this function?  I tried
using the "ImmSimulateHotKey" function API call, but every time I command
button is pressed, the result flag from the function is 0.  The current code
I tried is below.  Thanks in advance.

Private Declare Function ImmSimulateHotKey Lib "imm32.dll" _
                         (ByVal hwnd As Long, _
                          ByVal dw As Long) As Long
Private Const VK_CONTROL As Long = &H11
Private Const VK_SHIFT  As Long = &H10
Private Const VK_LETTER_S  As Long = 115
Private Const VK_HOTKEY  As Long = VK_CONTROL + VK_SHIFT + VK_LETTER_S

Private Sub cmdHK_Click()
  Dim I As Integer
  I = ImmSimulateHotKey(Me.hwnd, VK_HOTKEY)
  txtResults = Str(I)
End Sub

Matt, that's exactly what I did.  I discovered the solution last night and
it worked great.  My final solution follows.  Thanks for the tip.
