IWMSOnDemandPublishingPoint::get_AllowContentCaching
The get_AllowContentCaching method retrieves a Boolean value that indicates whether content from the publishing point can be cached.
Syntax
HRESULT get_AllowContentCaching( VARIANT_BOOL* pVal );
Parameters
pVal
[out] Pointer to a VARIANT_BOOL that indicates whether content can be cached.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
| Return code | Number | Description |
| E_POINTER | 0x80004003 | pVal is a NULL pointer argument. |
| NS_E_PUBLISHING_POINT_REMOVED | 0xC00D145AL | The publishing point has already been removed. |
Remarks
The default value is VARIANT_TRUE.
