InvisibleApp.DefaultAngleUnits property (Visio)

  • Article

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

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 under Display on the Advanced tab of the Visio Options dialog box (File tab > Options).

The return value contains one of the values of VisUnitCodes, which are declared in the Microsoft 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 as "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.

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.
