WMI: WDM Provider Rejects Dynamic Arrays Of Zero Length |
Q286803
The information in this article applies to:
- Windows Management Instrumentation, version 1.5, used with:
- the operating system: Microsoft Windows 2000
SYMPTOMS
The Windows Driver Model (WDM) Provider in Windows Management Instrumentation (WMI) rejects dynamic arrays of zero size. Any attempt to store an instance of an object that includes a dynamic array of zero size will result in an "Invalid Parameter" error.
As an example, the following MOF declares a variable length array.
class Test_DiagnosticsStatus { datetime timeoflastrun; uint16 numberofresults; [read,WmiSizeIs("NumberOfResults")] Test_DiagnosticsResult DiagResults[]; // Varying array };
The problem arises when the dynamic array (DiagResults[]) is of zero length.
DiagnosticsStatus = instance of Test_DiagnosticsStatus { NumberOfResults = 0; TimeOfLastRun = "16010101000000.000000+000"; };
Any attempt to store the above instance (DiagnosticsStatus) would result in an "Invalid Parameter" error (0x80041008).
