ID: Q88177

The information in this article applies to:

Microsoft Word for Windows, versions 1.0, 1.1, 1.1a, 2.0, 2.0a, 2.0a-CD, 2.0b, 2.0c, 6.0, 6.0a, 6.0c
Microsoft Word for Windows NT, version 6.0
Microsoft Word for Windows 95, versions 7.0, 7.0a
Word for the Macintosh, versions 6.0, 6.0.1

SUMMARY

The WordBasic commands to scroll through a document require the scroll bars to be active in Word. For example, if the horizontal scroll bar is not active when HScroll is called from a WordBasic macro, you may receive the following error message.

Word 6.x, 7.x

   WordBasic Err=544
   Unable to execute the scroll command; the scroll bar is not active.

Word 2.x

   WordBasic Err=509
   Command is unavailable.

WORKAROUND

Use the appropriate macro below to activate the horizontal scroll bar in the ToolsOptionsView dialog box, before using the HScroll() command.

Word 2.x, 6.x, 7.x

   Sub MAIN
      ToolsOptionsView .HScroll = 1
      n = HScroll()
      HScroll n + 20   'increases the horizontal scroll percentage by 20%
   End Sub

Word 1.x

   Sub MAIN
      ViewPreferences .HScroll = 1
      n = HScroll()
      HScroll n + 20   'increases the horizontal scroll percentage by 20%
   End Sub

If you are working with the vertical scroll bars and VScroll instead of HScroll, substitute VScroll for all occurrences of HScroll in the above macros.

MORE INFORMATION

The following list describes some of the functions and statements used in the above macros:

   HScroll <percentage> - Scrolls the file contents horizontally the
   specified percentage of the document width.

   n = HScroll() - Returns the current horizontal scroll position as a
   percentage of the document width.

   VScroll <percentage> - Scrolls vertically to the place in the
   document that is the specified percentage of the document's length.

   n = VScroll() - Returns the current vertical scroll position as a
   percentage of the document's size.
