Re: Owner Data ListView Ctrl failing to insert column in Vista

Sounds like a bug in the common controls on Vista.  You might want to make sure that the service pack is current.

Just a wild guess, but you might try NOT setting LVS_NOCOLUMNHEADER at create time, calling SetColumns(), and then doing your ModifyStyle(0, LVS_NOCOLUMNHEADER, TRUE) after the columns have been set.

I can imagine someone at MS writing code assuming that the header existed and was visible that would fail if it was not.
