Class LastHRESULT

      com.moesol.bindings.platform_sdk.component_services.LastHRESULT

public class LastHRESULT
extends ThreadLocal

Provide access to the raw value for the last HRESULT returned by a COM interface call generated by tlb2java. The tlb2java code generator transforms the return type of all [dual] methods so that the [retval] parameter is instead used as the return value. If there is no [retval] parameter void is returned. The original HRESULT is checked for a failure bit and if set a COMException is thrown. Occasionally, the HRESULT encodes additional information beyond success and failure. For example, IEnumVARIANT::Next is documented as returning S_OK, if all elements requested are retrieved, but S_FALSE if there are no errors but fewer elements than requested are returned. In these cases you can use LastHRESULT to get the actual HRESULT.

     LastHRESULT.instance().hresult();
 

This returns the last HRESULT returned by the last COM call on this thread.
