Hi Laurent, Thanks for the reply.
>Strange, i have LVIF_INDENT constant define in mingw commctrl.h file. >Do you have it in your commctrl.h file ? No, not present. Checked MinGW CVS and found it was in that one. Also found that SourceForge had a later version (3.1) and I had 2.something as I had not got MinGW from SourceForge. Installed 3.1 and it now compiles properly. I found your instructions for setting it up, very good. The only thing I obviously missed was not installing the most up-to-date version of MinGW. Chris
