PPT: Using LeftMargin or FirstMargin Yields Unexpected Results (173126)


The information in this article applies to:

  • Microsoft PowerPoint 98 Macintosh Edition
  • Microsoft PowerPoint 97 for Windows
This article was previously published under Q173126

SYMPTOMS

If you create a Microsoft Visual Basic for Applications macro or procedure to modify the LeftMargin and FirstMargin properties of the RulerLevel class, some values that are assigned to these properties produce unexpected results.

CAUSE

This problem occurs because the LeftMargin and FirstMargin properties allow you to assign invalid values to the properties.

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

There are five RulerLevel classes, each of which corresponds to a possible indent level. The FirstMargin and LeftMargin values of RulerLevel 1 have a valid range of (-9.0 to 4,095.0). The valid range of values for the FirstMargin and LeftMargin properties for RulerLevel classes 2 through 4 are described as follows.

For each RulerLevel L in the set {2, 3, 4, 5}, the following equations describe the minimum value for the FirstMargin and LeftMargin properties: 
   Min(RulerLevel(L).FirstMargin) = Max(RulerLevel(L-1).FirstMargin,
 
                                        RulerLevel(L-1).LeftMargin) + 9
 
   Min(RulerLevel(L).LeftMargin) = Max(RulerLevel(L-1).FirstMargin,
 
                                       RulerLevel(L-1).LeftMargin) + 9
If you assign a value that is between 4,096 and 8,182 to the FirstMargin or LeftMargin property, a sign bit is switched. The resulting values range from -4,096 to -10; these values are invalid. Assigning values that range from 8,183 to 8,191 results in values that range from -9 to -1; these values are valid.
