ok i need a clearer picture than that
Are we speaking of multi instance of the same form or are we speaking of multi forms..? either way it should be simple enough to do depending on what your code is like now
if you are making mult of the same form make a type in a module
Code:
Public Type
FormName As String 'umm name
FormID as Integer 'just a number
Form Loaded as Boolean 'still open..? this one is the most important
End Type
then at an iterval of your choosing loop through it and check the status of your forms and clean out any that aren't loaded so you don't get bogged down this is usually done for mdi application that have lots of the same document (form) open
