Hi Uri:

It could be an out dated DLL, see KB article:

PRB: OLE Error 0x80040154 "Class not Registered"
http://support.microsoft.com/support/kb/articles/q187/9/76.ASP

They are using the RichText control as an example, but this probably applies to the DatePicker also. Good luck in trying to find Oadist.exe, because I can't find it. I think Microsoft is restructuring their website.

HTH,

OLE object is being ignored. Record number 24". I've opened the .scx as table and record number 24 is DateTimePicker control. I thought, that it's because it needs its localized DLL.
