1024

messagebox("a" + replicate(".", 1022) + "z")
messagebox("a" + replicate(".", 1023) + "z")

can you try this please. in a sample form put in a grid with one column and in that col's DynBC = IIF(.T., RGB(255,255,255), "a..............................................................................................................................................................................................................................................................z")

Put in a messagebox() to this property somewhere close and run the form and see the messagebox giving you truncated value. Now open the form and Zoom this property, trucated!!!
