There are few tools I would say that I use *every* day. This is one of them.
ERR.exe is a tool I use all the time to look up error codes. When someone
gives me an error code, the first thing I do is toss it in err so I know
what I’m looking at. For example:
# for decimal 8402 / hex 0x20d2 :
# The data type of the ‘%s’ must be ‘%s’. ‘%s’ is not
# The class could not be cached.
# 2 matches found for “8402”
Note that it doesn’t just look in a single .h….it looks in many at once! And not just Windows either. Very handy.
