I have a fairly long and complex processing loop that can take a very long time when opening a large file. I have isolated the very core central processing of the loop and placed it in a stand-alone method in preparation to put that method into a thread. A couple quick questions before I make the final plunge... First question: The main looping process (the thread) will be filling a database with information from the file being read . The next step after reading the file and loading the database (when the thread ends) is to fill a list box from the data in the database. Since I can't fill the list box until the thread ends, how do I get my process to suspend until the thread completes filling the database? That is, how do I essentially twiddle my thumbs until the thread ends? Second question: Since the thread is reading a file and loading a database, there are some necessary error-checking processes that that could (in an extreme case) display a MsgBox with an error message informing the user of some unexpected error situation. Can I display a MsgBox in the middle of executing a thread? Thanks to all - this is a really great support group.
