Type: Function
Return Data Type: Boolean

Syntax

Function IsComObjectCreated Returns Boolean

Call Example

Get IsComObjectCreated to BooleanVariable

Description

You can test to see if a COM object exists by getting the value of IsComObjectCreated.

This is analogous to testing if the pvComObject property is Not Null (created), or Null (released).

Testing IsComObjectCreated is crucial to writing error free COM applications. You should test this value before executing any code that accesses a COM object's interface methods or properties. The exception to this rule is when you access a COM object inside an OnCreate event handler.

Refer to the CreateComObject method for an example showing the use of IsComObjectCreated.

Return Value

This function returns True, if the COM object has been created indicating that it is safe to access its interface.
