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.
