What exactly does ERROR_INVALID_ORDINAL mean?

Question

The LoadLibrary function returns me error code 182. From MSDN:

ERROR_INVALID_ORDINAL: "The operating system cannot work% 1"

Does anyone have a better description of what this error is?

Answer 1

A very obscure mistake. However, the term "serial number" is closely related to the DLL. The DLL contains a list of exported functions, as well as a list of imported functions. Other dll files that it relates to. These exports and imports are usually named, but this is not required. They always have a number, a number is a "serial number".

To start diagnosing this, use the Dumpbin.exe SDK tool. Run this first:

Dumpbin /exports Blah.dll

Dumpbin /imports Blah.dll
