Ever get an Hresult error code and have no idea what it meant or how to figure out what it's related to?
The SSIS run time engine and the data flow engine are written in native code. Therefore, many errors are returned as Hresults. In case your unfamiliar with what an Hresult is, below is a Wikipedia definition for Hresult.
In the field of computer programming, the HRESULT is a data type used in many types of Microsoft technology. HRESULTs are used as function parameters and return values to describe errors and warnings in a program.
An HRESULT value has 32 bits divided into three fields: a severity code, a facility code, and an error code. The severity code indicates whether the return value represents information, warning, or error. The facility code identifies the area of the system responsible for the error. The error code is a unique number that is assigned to represent the exception. Each exception is mapped to a distinct HRESULT.
Now that you know what Hresults are, you can look up their mappings (for SSIS) using the link below.
