Existing .h file no longer color coded

[Bill Johnson]

I have a .h file in a given directory that is no longer color coded when opened in SlickEdit. It is the only file in the directory that is not color coded when opened.  The same file is color coded if it resides in a different directory.  The file was color coded fine yesterday. Any ideas how to fix this.  (Thanks)

It sounds like somehow it got set to a different mode.  With the file open, go to Document>Select Mode and choose "C/C++".

Thanks, that was the problem.
