Bug ID: 50511
           Summary: Datetime conrtol doesn't handle WM_SYSKEYDOWN/VK_DOWN.
           Product: Wine

Created attachment 69175
  --> https://bugs.winehq.org/attachment.cgi?id=69175
a quick hack.

Some .net applications implement a button for showing the dropdown of DateTime
control by themselves. And the button sends WM_SYSKEYDOWN/VK_DOWN to DateTime
control actually. So without this message implemented, nothing will be shown
after clicking the button.

Attached is a quick hack that made the application I tested happy. But we may
still need some tests for it for upstream.
