Not very refreshing?

Does anyone know how I can refresh the whole screen including objects outside my visual basic project?

I am assuming that this will require some kind of API call.

I can think of 2 ways of doing it, The first way is much easier and faster and works a lot better that I anticipated, so use that.


you need these APIs

Private Declare Function UpdateWindow Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetDesktopWindow Lib "user32" () As Long

and just call it with

Call UpdateWindow(GetDesktopWindow)

this refreshes the desktop window, which basicly means the screen

Just in case you're interested the secons uses EnumWindows to Get a handle to every window on the screen and refreshes them all individually

Put this in a standard module

Private Declare Function UpdateWindow Lib "user32" (ByVal hWnd As Long) As Long


Public Sub RefreshScreen()
Call EnumWindows(AddressOf EnumProc, 0)
End Sub


Public Function EnumProc(ByVal hWnd As Long, ByVal lParam As Long) As Long

Call UpdateWindow(hWnd)
EnumProc = 1
End Function

Then use RefreshScreen to refresh the whole screen.

Use the first one.

Thankyou that was very helpful!
