"If the regex string is embedded in the C++ source then those backslashes will need to be doubled to \\d." Thanks John. The regex strings are read from file. For the example "^(XXX_\d{3,3})_\d{3,3}$" actually exists as ^(XXX_###)_###$ in the file and is converted programmatically to example string. The only ones that seem to fail are ones that begin with "^(.....". In strings like "^...(..." there doesn't seem to be a problem. The strings run against the regex are read from a database. Again, the odd thing is if I remove the parenthesis [^XXX_###_###$] it works and the correct strings are found. I'll do a bit of experimenting with it and will post a condensed test program if I can't pin it down.

I have probably missed something in the doc that answers my query but I just can’t see it.
If the regex string is embedded in the C++ source then those backslashes will need to be doubled to \\d. Other than that I don't see anything wrong, can you please post a complete self-contained text case so we can see where you're going wrong?
