Sprinkling TRACE statements in your code is a common practice during development and debugging, especially when refereshing UI code, or multi-threading, etc.

Usually, people write something like this:

 TRACE("My Trace
");

The end-of-line char (
or
) is there to separate different TRACE statements in the output window. However, if the code already contains a lot of TRACE statements without new line terminators, your TRACE statements might be printed at the end of some long TRACE statement and not visible.

To make sure your TRACE statements are always on a new line just put the new line char at the beginning:

 TRACE("
My Trace");
