3.10.4.1 InstanceName (Set) (Opnum 10)

  • Article

The InstanceName method sets the web server instance to be used by subsequent method calls.

 [propput, id(4)] HRESULT InstanceName(
   [in] BSTR newVal
 );

newVal: A string that specifies the web server instance.<33>

Return Values: A signed 32-bit value that indicates return status. If the method returns a negative value, it failed. If the 12-bit facility code (bits 16–27) is set to 0x007, the value contains a Win32 error code in the lower 16 bits. Zero or positive values indicate success, with the lower 16 bits in positive nonzero values containing warnings or flags defined in the method implementation. For more information about Win32 error codes and HRESULT values, see [[MS-ERREF].
