Error Lookup utility

The Error Lookup Tool, also known as “ErrorLookup“, is a dialog-based Window application to decode many type of error codes. It does not require elevation and is very easy to use.

ErrorLookup tool can be used instead of standard errlook.exe shipped with Microsof Visual Studio. The error lookup utility is a much more powerful tool. In particular, it allows converting both from the error code to its detailed description and to the name of a constant. also it can perform the inverse conversion from the constant name to the error code. At the same time, in addition to WIN32 (LRESULT) and HRESULT codes, it supports NTSATUS, KRETURN, errno, IPP Status, HTTP status codes.

Some error/status codes correspont to more than one constant. The utilty displays their list and allows to choose correct one. You can also set OS filter, to specify which operating system you are interesting on.

AllStat Error Lookup utility












When the ErrorLookup program starts, it analyzes the contents of the clipboard. If Windows clipboard contains a text that can be interpreted as an error code or the name of a constant, the program automatically switches to the appropriate tab (“Code to name” or “Name to code”) and displays information about the value.

You can sort the values in the list by clicking on the column name.
