Excel & Word have the Screen Updating method thru which a developer can lock the main window from unnecessarily redrawing itself whilst the macro is being executed. If left alone, redrawing is not only ugly on the eyes it also takes more time for the macro to reach completion.

' --------------------------------------------------------------------------------' 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.

Doing this should help improve the performance of your code: ‘Get current state of various Excel settings; put this at the beginning of your code screen Update State = Application. : This setting tells Excel to stop showing status while False.

For example, if you use VBA to copy/paste a range, while the paste is completing Excel will show the progress of that operation on the status bar.

Open("C:\sample.pps", _ With Window:=mso False) 'Open a window now to the presentation for editing p Show.

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

While looking into Excel VBA performance issues I learned that some desktop search tools implement event listeners (probably to better track document contents as it changes).

You might not want Excel firing an event for every cell you’re changing via code, and turning off events will speed up your VBA code performance if there is a COM Add-In listening in on Excel events.

There are tons of sites, pages, and people who are experts as well on this subject, have performed their own tests, and shared their results and ideas.

If you think I missed an important concept for how to optimize Excel VBA performance, or if you’ve got a valuable comment or link to share, please feel free to post here so everyone can benefit. Turn Off Everything But the Essentials While Your Code is Running This optimization explicitly turns off Excel functionality you don’t need to happen (over and over and over) while your code runs.

“Automatic” is the default and means that Excel decides when to recalculate the workbook (e.g. Since recalculating your workbook can be time and resource intensive, you might not want Excel triggering a recalc every time you change a cell value.

Turn off calculation while your code executes, then set the mode back.

Note that in the code sample below we grab the current state of these properties, turn them off, and then restore them at the end of code execution. Display Page Breaks = False ‘note this is a sheet-level setting ‘: This setting tells Excel to not redraw the screen while False.
