I am looking for a control to add to userForm to enable a user to pick the date. I found a good one at this address
Formatting MM/DD/YYYY dates in textbox in VBA
Just throw some light in to some issues related to this control.
Date picker is not a standard control that comes with office package. So developers encountered issues like missing date picker controls when application deployed in some other machiens/versions of office. In order to use it you have to activate the reference to the .dll, .ocx file that contains it.
In the event of a missing date picker, you have to replace MSCOMCT2.OCX file in System or System32 directory and register it properly. Try this link to do the proper replacement of the file.
In the VBA editor menu bar-> select tools-> references and then find the date picker reference and check it.
If you need the file, download MSCOMCT2.OCX from here.
