Koen,

>>I am looking for a datetimepicker class

There's a few around, but many of them date from the pre-Metro or even pre-Aero era, so they tend to mimic the original ActiveX version with hand-drawn circle for today's date or use non-standard colors. More recently there's a quite nice Sweetpotato option, but it relies on a READ/CLEAR EVENTS to pause for the calendar, meaning it doesn't work so well in a normal app that already has its READ EVENTS.

I was attracted to the ctl32_datepicker class with its really modern-looking calendar and interface (uses a combobox so you get prevailing Windows appearance) but there's no way to edit the time portion. So I subclassed it, adding a txtTime but also an invisible txtControlsource for databinding. If date or time value is edited, update txtcontrolsource.value (if it changed) for databinding. Worth checking out the ctl32_datepicker to see if you like the look of it and it's pretty easy to subclass.
