I am using Microsoft Date and Time Picker control(SP4) in my application.My application runs fine in xp and vista machines as date and time picker refers to mscomct2.ocx which is present in system32 for xp and vista,but for windows 7 i dont have this dll in my system .In windows we need admin rights to register that control. So is there any alternative/similar control available.......It would be helpful if you could let me know why thats not available in windows P.S : My Application is a .Net application and the reason why i have used Microsoft Date and Time Picker control(SP4) instead of .Net provided control is to display year 9999.
