IWMSActiveScriptAdmin::get_EnableDebugging

The get_EnableDebugging method retrieves a Boolean value that indicates whether the Microsoft Script Debugger can be used to debug the script.

Syntax

Parameters

pVal

[out] Pointer to a VARIANT_BOOL indicating whether the Microsoft Script Debugger can be used.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
