How to log messages with &-Token in it?

[extreme001]

Hi!

I downloaded a file that contains %-Token in it's filename. While reading it line by line i get a general FORMAT-Issue. The file was renamed by the browser. Any idea on how to read it if there are %-Token in the filename that is pushed wxLog?

The errorline:

Code: Select all

wxLogMessage(wxString::Format(_T("Parse: %s"), filename));

Here's the screenshot:

How to resolve it?

Thank you very much!!!

wxLogXXX methods already are printf-like, so you don't need the wxString::Format. And in this case it's responsible for the problem, because the string gets parsed twice.

Code: Select all

wxLogMessage( _T("Parse: %s"), filename );

You still have to do something about "%" in the string, if it is not a printf format specifier. What I do is to send strings coming from a user / of unknown origin through a function that doubles the "%" before passing them to wxLog...(). Not a very good solution, I'd like to learn a better one myself.

doesn't wxLog("%s", your_string_with_stuff_in_it) just work for that??

Yes, of course it does. IIRC I had a situation in which this was not a good solution, but for the life of me I can't now remember why was that.

Yes...i hoped there would be a routine, a method or something which does it for me.
Thank you very much!
