Using SendMessageLong to make a combo box drop down list longer...
The Win32API.txt file list 2 constants that you can pass to the SendMessageLong
declaration to extend the width of a combo box when you click the drop down
arrow.[CB_GETLBTEXTLEN will allow you to get the length of the ListItems]
and [CB_SETDROPPEDWIDTH will allow you to set the width of the combo box
when the drop down arrow is clicked. Can anyone give me the constants that
you pass into 1) check the combo box drop down length, 2) Set the combo box
drop down length.............thx
