PercentCompleteScalar Property

Gets or sets the scalar value by which to divide the current conversion completion percentage.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Overridable Property PercentCompleteScalar As Integer

'Usage
 
Dim instance As ConvertCtrl
Dim value As Integer
 
instance.PercentCompleteScalar = value
 
value = instance.PercentCompleteScalar

public virtual int PercentCompleteScalar {get; set;}

public:
virtual property int PercentCompleteScalar {
   int get();
   void set (    int value);
}

Property Value

A value representing the percentage complete as a scalar value.

Remarks

The programmer divides the PercentComplete property value by this property value to determine the actual percentage complete. For example, if the scalar value is 100 and the PercentComplete property equals 50, then the process is 50/100 complete (0.5 percent) instead of 50 percent. Likewise, if the scalar is 1 and the programmer gets a percent complete value of 50, then the percentage complete is 50/1, or 50 percent complete.
