I am using WinSchedule. I am using it bound to a BBS. Everything is fine except when I try to bind the allproperties databindingmember.allproperties to a column which is configured as a VarBinary = Max. I am getting the following error when loading.

Sorry, I am not going to be much help.  We wrote our own scheduling controls for our medical software due to a number of issues and limited extensibility on these controls.  So it has been quite a while since I even dropped one of their scheduling controls on a form.  This might be one better directed towards their forum since they understand the inner workings of the control.

Thanx Trent!

Wish I had the ability to roll my own. These controls present one challenge after another. I am so close. I have a lot of the scheduling working. Just this stupid issue with the column type!
