InvisibleApp.DefaultAngleUnits Property

  • Article
Visio Automation Reference

Determines the default unit of measure for quantities that represent angles. Read/write.

Version Information
 Version Added:  Visio 2002

Syntax

expression.DefaultAngleUnits

expression   A variable that represents an InvisibleApp object.

Return Value
Variant

Remarks

The DefaultAngleUnits property corresponds to the value shown in the Angle box on the Units tab in the Options dialog box (on the Tools menu, click Options).

The return value contains one of the values of VisUnitCodes, which are declared in the Microsoft Office Visio type library.

You can specify the value of the DefaultAngleUnits property as an integer (a member of VisUnitCodes) or a string value such as "degrees". If the string is invalid or the unit code is inappropriate (non-angular), an error is generated.

For a complete list of valid unit strings along with corresponding Automation constants (integer values), see About Units of Measure.

Cell formulas that contain a specific unit of measure are displayed in those units regardless of the default angle units setting. Many cell formulas, however, use implicit unit syntax and are displayed in default units.

A program can create a cell whose formula is displayed in default units by setting the cell's Formula property to a string in implicit unit syntax. For example, if the formula for the angle of a shape is "=90[deg,A]" , the result is displayed as "90 deg." if the DefaultAngleUnits property is visDegrees, and "1.5708 rad." if the DefaultAngleUnits property is visRadians.

Alternatively, a program can use the following statement to set the cell's result to default angle units:

Visual Basic for Applications 
      vsoCell.Result(visAngleUnits) = 90

In this case, the result is 90 degrees if the DefaultAngleUnits property is visDegrees, and 90 radians if the DefaultAngleUnits property is visRadians.

For details about implicit units of measure, see About Units of Measure.
