Syntax

 

[Visual Basic]

Public Function CallbackForCastingEventsSet (

function as CallbackForCastingEvents

) as enumErrorCodes


 

[C#]

public enumErrorCodes CallbackForCastingEventsSet (

CallbackForCastingEvents function

);


 

[C++]

public: enumErrorCodes CallbackForCastingEventsSet (

CallbackForCastingEvents function

);


 

 

Parameter

Description

 

 

function

Callback function that will receive events generated by the casting manager. Remember that callback functions must be as fast as possible in order to avoid slowing down overall performances.

 

 

when using the API from Unmanaged C++ through COM interaction, where the client application is totally unaware about .NET delegates, you should use the "Ptr" version of the method which allows passing the pointer to the callback function:

 

[Unmanaged C++]

enumErrorCodes CallbackForCastingEventsSetPtr (

(UINT_PTR) functionPointer

);


 

Parameter

Description

 

 

functionPointer

Pointer to the callback function.

See the Adding the API to an unmanaged Visual C++ project tutorial for details about usage of the "Ptr" version of these methods.

 

 

Return value

 

Value

Meaning

 

 

Negative value

An error occurred (see the LastError property for further error details)

enumErrorCodes.NOERROR (0)

The method call was successful.
