XL97: Macro Performance Slow When Page Breaks Are Visible
ID: Q145598
|
The information in this article applies to:
-
Microsoft Excel 97 for Windows
SYMPTOMS
When you run a Visual Basic for Applications macro in Microsoft Excel 97,
the macro may take longer to complete than it does in earlier versions of
Excel. For example, a macro that required several seconds to complete in an
earlier version of Excel may require several minutes to complete in
Microsoft Excel 97.
CAUSE
This problem may occur if the following conditions are true:
- Your Visual Basic macro modifies the properties of many rows.
-and-
- You have performed an operation that forced Excel to calculate page
breaks. Excel calculates page breaks when you perform any of the
following operations:
- You display a Print Preview of your worksheet.
- You click Page Setup on the File menu.
- You modify any of the properties of the PageSetup object in a Visual
Basic macro.
-and-
- You have selected the Page Breaks check box on the View tab of the
Options dialog box.
This problem occurs if your macro sets any PageSetup property, or if you
manually set a PageSetup property, and you then run a Visual Basic macro
that sets properties on a large range of rows. Setting PageSetup properties
turns on automatic calculation of page breaks in Microsoft Excel 97. By
default, this property is not turned on.
WORKAROUND
To work around the problem, use either of the following methods.
Method 1: Manually Turn Off the Display of Page Breaks
To manually turn off the display of page breaks, follow these steps:
- On the Tools menu, click Options.
- Click the View tab. Under Window Options, click to clear the Page Breaks
check box. Click OK.
Method 2: Turn Off the Display of Page Breaks in Your Macro

To work around the problem, add the following line of code to your Visual
Basic macro:
ActiveSheet.DisplayPageBreaks = False
NOTE: This line of code must be inserted after you modify any of the
properties of the PageSetup object, but before you modify the properties or
the rows on your worksheet.
