RegisterUserDefinedFunction Method (UltraWebCalcManager)

Registers an individual UltraCalcFunction with the calculation engine.

Syntax

Visual Basic

'Declaration
 
Public Function RegisterUserDefinedFunction( _
   ByVal userDefinedFunction As UltraCalcFunction _
) As Boolean

C#

public bool RegisterUserDefinedFunction( 
   UltraCalcFunction userDefinedFunction
)

Parameters

userDefinedFunction

User-defined function instance to register.

Return Value

Returns true if the type was registered successfully, else false if the registration failed.

Remarks

Developers can build custom functions for use within their formula expressions by sub-classing the UltraCalcFunction class.

Once the derived class is instantiated, it must be registered by using this method before it becomes available to formulas.

Developers can build libraries of functions packaged into an assembly, and register all UltraCalcFunction subclasses within that assembly by using the RegisterUserDefinedFunctionLibrary method.
