PeteJM,
I could not find any samples nor tutorials of how to do Gantt style chart on continuous MS Access forms without ActiveX. The method that I developed uses bound function that builds variable length strings of fixed-size box font (LaBox tt font, licence free...). The main difficulty is not programming but building graphic UI, which took few nights of trial & error. Control label is drawn over the timeline, allowing user to double-click on the chart, which passes X and Y mouse click parameters to other functions.
I will work on sample database and post it online.
