Hiya - I'm trying to find out how I can respond to a column resize in a TListView control (in report view mode), theres no event for it, and I can't find a message to trap, I saw that HDM_GETITEMW gets called, but that's not known to delphi, and there were a few WM_USER+xxx's trigger, but I havn't tried to respond to those yet... Does anyone know what message I should respond to? Or is there something I'm simply over looking? -- Mark Derricutt, PB Power NZ Ltd (http://www.pbpower.net) Getting jiggy with Stratovarius - Babylon --------------------------------------------------------------------------- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz
