IContentListSchema::get_Locked, put_Locked Property
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.
The Locked property is a read/write Boolean that indicates whether the ContentListSchema object can be modified. A value of True indicates that the schema is locked and cannot be modified. A value of False indicates that the schema is not locked and can be modified. Once the object is in use it can no longer be modified.
HRESULT IContentListSchema::get_Locked(
VARIANT_BOOL* Locked
);
HRESULT IContentListSchema::put_Locked(
VARIANT_BOOL Locked
);
Property Locked() As Boolean
Parameters
Locked
[C++][in] When setting the property, a VARIANT_BOOL that specifies a new lock setting. Since schemas, once locked, cannot be unlocked, only the first call to this method with the Locked parameter set to True will have any effect.
[out,retval] When getting the property, a pointer to a VARIANT_BOOL used to return the state of the schema lock. A value of True indicates that the schema has been locked. A value of False indicates that the schema not yet been locked.
Return Value
[C++]
These methods return an HRESULT indicating whether they completed successfully. See the Error Values section for more details.
[Visual Basic]
None.
Error Values
[C++]
These methods return S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.
[Visual Basic]
This property sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.
Remarks
A ContentListSchema object becomes permanently locked as soon as this property is set to True. Once locked, the contained schema cannot be modified or unlocked. ContentListFactory objects will lock the schema as soon as any rows are allocated or any ContentList objects are created, whichever occurs first.
