Capture Desktop Image to File

Can someone give me code to capture an image of your desktop and save it to a bmp file?

VB Code:

Declare Function GetDesktopWindow Lib "user32" Alias "GetDesktopWindow" () As Long
 
Declare Function GetDC Lib "user32" Alias "GetDC" (ByVal hwnd As Long) As Long
 
Dim dhandle As Long
dhandle = GetDesktopWindow
Dim ddc As Long
ddc = GetDC(dhandle)

Now just use BitBlt to draw the contents of the ddc DC to your pic box. Then just use the SavePicture method to save it to a file.

Try this:

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, _
ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

Private Const VK_SNAPSHOT = &H2C
