I use this property a lot in Excel to stop any screen changes being shown to the user as a macro is running. Does anyone know of a way to stop any screen changes being visible to the user in MS Project as a macro is running?? I use this property a lot in Excel to stop any screen changes being shown to the user as a macro is running. Does anyone know of a way to stop any screen changes being visible to the user in MS Project as a macro is running?? You can do this with API calls, but that can lead to issues.You don't have to lock the entire desktop if you use Lock Window Update (you do have to be careful of course) Option Explicit Private Declare Function Find Window Lib "user32" Alias "Find Window A" (By Val lp Class Name As String, By Val lp Window Name As String) As Long Private Declare Function Lock Window Update Lib "user32" (By Val hwnd Lock As Long) As Long Sub Lock Project() 'To lock a window we'll use the Lock Window Update function, part of the Win32 API 'It accepts an argument that is a long, this refers to the handle of the window 'to be locked. Perhaps it is something to do with opening the documents.?

lng Handle = Find Window("JWinproj-Whimper Main Class", Application.

' --------------------------------------------------------------------------------' User Defined Error codes Const ERR_NO_WINDOW_HANDLE As Long = 1000 Const ERR_WINDOW_LOCK_FAIL As Long = 1001 Const ERR_VERSION_NOT_SUPPORTED As Long = 1002 ' API declarations for Find Window() & Lock Window Update() ' Use Find Window API to locate the Power Point handle.

Declare Function Find Window Lib "user32" Alias "Find Window A" _ (By Val lp Class Name As String, _ By Val lp Window Name As Long) As Long ' Use Lock Window Update to prevent/enable window refresh Declare Function Lock Window Update Lib "user32" _ (By Val hwnd Lock As Long) As Long ' Use Update Window to force a refresh of the Power Point window Declare Function Update Window Lib "user32" (By Val hwnd As Long) As Long Property Let Screen Updating(State As Boolean) Static hwnd As Long Dim Version No As String ' Get Version Number If State = False Then Version No = Left(Application. Version, ".") - 1) ' Get handle to the main application window using Class Name Select Case Version No Case "8" ' For PPT97: hwnd = Find Window("PP97Frame Class", 0&) Case "9" ' For PPT2K: hwnd = Find Window("PP9Frame Class", 0&) Case "10" ' For XP: hwnd = Find Window("PP10Frame Class", 0&) Case "11" ' For 2003: hwnd = Find Window("PP11Frame Class", 0&) Case "12" ' For 2007: hwnd = Find Window("PP12Frame Class", 0&) Case "14" ' For 2010: hwnd = Find Window("PPTFrame Class", 0&) Case "15" ' For 2013: hwnd = Find Window("PPTFrame Class", 0&) Case Else Err.

New Window ' Unlock the window to start refreshing again Screen Updating = True Exit Sub Err Handle: If Err.

By Michael Alexander As your Excel macros become increasingly robust and complex, you may find that they lose performance.

Here is a variable to store the handle: Dim lng Handle As Long 'lockwindowupdate returns a zero if it failed, so heres a container for checking 'the return Dim Ret As Long 'we'll use this in the "error trap" Dim bln Tried Already As Boolean 'To find the handle for the Project window we'll use the Find Window function, again part 'of the Win32 API.
