I posted this here before:

and was told this might be a better place...

During a build, if I arrange to output text in this format:

  "c:\\file.txt(10) : warning RPB1001: wibble is a silly word"

[For example, with a #pragma message in C++, from an external tool as part
of a post-build event, and so forth]

then I get an entry in the Error List window like this:

 Cat  Ord   Description                                 File       Line
 ------------------------------------------------------------------------...
  !    1    warning RPB1001: wibble is a silly word     file.txt    10

If I output text like this:

  "c:\\file.txt(10) : error RPB1002: wibble is too silly a word"

then I get an entry in the Error List window like this:

 Cat  Ord   Description                                 File       Line
 ------------------------------------------------------------------------...
  x    1    error RPB1002: wibble is too silly a word   file.txt    10

Now, at the top of the Error List window there are three buttons to turn
on/off display of "Errors", "Warnings" and "Messages".  However, if I try
writing "message" (or "info", "information", "comment", ...) to the build
output instead of "warning" or "error", nothing gets picked up in the Error
List window when I toggle "Messages" on.

Could someone *please* tell me how to get the Error List window to pick up
the "Messages" that it purports to be able to filter and display?  I've
searched the help and have searched online to no avail.

Thanks!
