ICanHandleException::CanHandleException

Determines if the caller of the script engine can handle a specified exception.

Syntax

HRESULT CanHandleException(  
   EXCEPINFO*  pExcepInfo,  
   VARIANT*    pvar  
);  

Parameters

pExcepInfo
[in] Pointer to an EXCEPINFO structure containing the information that will be reported if no exception handler is found.

pvar
[in] A value associated with the exception, such as the value thrown by a throw statement. This parameter may be NULL.

Return Value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Value	Description
S_OK	The caller can handle the exception
E_FAIL	The caller cannot handle the exception.

Remarks

If a call to IDispatchEx::InvokeEx, or a similar method, results in an exception, the script engine checks for a caller in the script's caller chain that supports the ICanHandleException interface and indicates that it can handle the exception. If no caller can handle the exception, the script engine halts.
