Invalid use of Null. Probably coming from a VB6 COM DLL, where a Null value is being used improperly (i.e., something is Null that shouldn't be) | |||||
0x80070005 |
Permissions problem when registering DLL? Make sure you are in an elevated command prompt when trying to register (Administrator in the command window) | |||||

Error accessing the OLE registry | ||||

A VB6 result error code (more info needed) |
Tips
- When searching for the decimal code, be aware most search engines will exclude that term from search results because of the negative sign. Instead, surround the term with speech marks to prevent that:
"-2147467259". - Try various searches for the hex code, decimal code and constant to find various results.
- Sometimes the error code will be from another platform or framework, for example,
900a005eis from VB6.
Example
REGDB_E_CLASSNOTREG
The error code will look like this in .NET: 0x80040154 (word) or 0xFFFFFFFF80040154 (dword), or a decimal value of 2147746132 (1 word) or –2147221164 (dword)
Here's how it looks defined in winerror.h:
#define REGDB_E_CLASSNOTREG _HRESULT_TYPEDEF_(0x80040154L)HRESULT
The HRESULT numbering space is vendor-extensible. Vendors can supply their own values for this field, as long as the C bit (0x20000000) is set, indicating it is a customer code.
The HRESULT numbering space has the following internal structure. Any protocol that uses NTSTATUS values on the wire is responsible for stating the order in which the bytes are placed on the wire.
S(1 bit): Severity. If set, indicates a failure result. If clear, indicates a success result.R(1 bit): Reserved. If the N bit is clear, this bit MUST be set to0. If the N bit is set, this bit is defined by theNTSTATUSnumbering space.C(1 bit): Customer. This bit specifies if the value is customer-defined or Microsoft-defined. The bit is set for customer-defined values and clear for Microsoft-defined values.N(1 bit): If set, indicates that the error code is anNTSTATUSvalue, except that this bit is set.X(1 bit): Reserved. SHOULD be set to0.Facility(11 bits): An indicator of the source of the error. New facilities are occasionally added by Microsoft.Code(16 bits)
