VBA programs are known to save a lot of time and now this post is to save further time. * An operation has been performed that forced Excel to calculate page breaks.
This means that Excel is constantly tracking various actions to determine if something should be done. Get Seconds Elapsed ' With performance settings m_Timer. The second time the routine is called it will write values 1501 to 3000, which takes ~2 seconds with Speed-Up running the first time (and ~1 second for subsequent runs i.e. A message box will report the overall speed increase at the end: For individual timings, see the Immediate Window (show results).
In some cases, you can increase your codes performance by turning these checks off (when the events are unnecessary). Name = C_NAME_SHEET End If ' Without performance settings. In an effort to increase performance, I did not include these options in the Speed-Up class as page breaks are hidden by default, and I never use pivot tables…
This is particularly so when routines generated by the macro recorder are used without cleaning-up unnecessary “Select” statements (which slows performance).
Even so, the Speed-Up class can even make such auto-generated routines faster without very much modification.
Here I make use of the Stop Watch class to measure the performance with speed on/off:''' ''' Illustration of Speed Up class for Excel. However, the existing code can easily be amended to include these options.
''' (Performance increase by factor of ~10 over default application settings.) ''' Private Sub Demo Speed Up() Dim timer As New Stop Watch Dim speed Up As New XLSpeed Up Dim ws As Excel. For page breaks:''' ''' Turns on/off [workbook] page breaks.
As with most of the other class I develop, standard boilerplate properties are included: Excel continuously redraws the screen to show the current state of workbooks and sheets.
Disabling screen updating saves system resources, allowing your VBA code to run faster.
You must set the Screen Updating property to True when the procedure finishes or when it stops after an error. Turn off automatic calculations: Whenever content(s) of a cell or range of cells are changed, the formulas dependent on them and Volatile functions are recalculated.
