These are all programs to capture the screen. Including the source-files.


run the code and press spacebar:

Option Explicit
Private Type POINTAPI
       x As Long
       y As Long
End Type
Private Declare Function GetDesktopWindow Lib "user32" () As Long
Private Declare Function GetWindowDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetCursor Lib "user32" () As Long
Private Declare Function DrawIcon Lib "user32" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal hIcon As Long) As Long
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long

Dim hwndDW As Long
Dim dcDW As Long
Dim pt As POINTAPI
Private Sub Form_KeyPress(KeyAscii As Integer)
With Me
  If KeyAscii = 32 Then 'spacebar
     GetCursorPos pt
     BitBlt .hdc, 0, 0, .ScaleWidth, .ScaleHeight, dcDW, 0, 0, vbSrcCopy
     DrawIcon .hdc, pt.x, pt.y, GetCursor
  End If
End With
End Sub

Private Sub Form_Load()
hwndDW = GetDesktopWindow()
dcDW = GetWindowDC(hwndDW)

End Sub
