Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • temporary mpx files

    How do I get rid of temporary mpx files ?
    when I try to use tbl.query_detach_all() I get the following message even though the table and all of it's forms are closed

    Script:OnInit line:29
    tbl.query_detach_all()
    The process cannot access the file because it is being used by another process.

    Re: temporary mpx files

    One way possibly would be a file deletion as your app starts each time? They may not have all gotten deleted even though you have detached them. They also do not want to be deleted if they think they are getting used. On start (autoexec script) can call a script (or other) to mass delete them. It could even call a batch file ( not as nice as a script though).

          Re: temporary mpx files

          That script Charlie Crimmel posted was created by me in 2002 - I imagine he just didn't remember where it came from. Here's a minor update that also puts it into a function. I keep it in my code library for easy access. I've been using this in the autoexec of virtually every app I've built since 2002 and it has solved the problems for me. It doesn't always remove every "$$" file because sometimes they are still being used. However, it does keep them from building up to ridiculous numbers.

          Code:
          'Date Created: 22-Oct-2004 01:30:40 PM
          'Last Updated: 22-Oct-2004 11:20:32 PM
          'Created By  : Cal
          'Updated By  : Cal
          
          FUNCTION Del_dollar AS C ( )
          'Description: Deletes all files in the database that start with "$$".  This includes the Data path (local path if running network optimized), Private path, and Executables path.  Returns count of files deleted as char.
          '-----------------------------------------------------------------------
          ' THIS SCRIPT DELETES ALL FILES IN THE DATABASE THAT START WITH "$$".
          ' THIS INCLUDES THE DATA PATH (start-in), PRIVATE PATH, AND EXECUTABLES PATH.
          '-----------------------------------------------------------------------
          ' SET THE PATH NAMES TO AN ARRAY FOR LOOPING.
          '-----------------------------------------------------------------------
          DIM path[10] as c
          path[1] = a5.get_path() + chr(92)
          path[2] = a5.get_private_path() + chr(92)
          pcount = 2
          IF a5.get_private_path() <> a5.get_exe_path()
           path[3] = a5.get_exe_path() + chr(92)
           pcount = 3
          END IF
          '--- DON'T BOTHER WITH THE SHARED PATH or MASTER PATH BECAUSE IT SHOULD
          '--- NEVER PUT THESE FILES THERE.
          '-----------------------------------------------------------------------
          ' NOW DELETE ANY "$$**.*" FILES THAT ARE NOT LOCKED.
          '-----------------------------------------------------------------------
          fcount = 0
          FOR x = 1 to pcount
           type_of_files = 0 + FILE_FIND_ARCHIVE + FILE_FIND_READONLY + FILE_FIND_HIDDEN
           dfiles = filefind.get( path[x] + "$$*.*", type_of_files, "PN" )
           FOR qx = 1 to line_count( dfiles )
            fname = word( dfiles, qx, crlf() ) '*** GET THE FILE NAME.
            ON ERROR goto Continue_next '*** FIND OUT IF THE FILE IS LOCKED.
            fp = file.open( fname, file_rw_exclusive )
            ON ERROR goto 0
            fp.close() '*** FILE IS NOT LOCKED SO CLOSE IT AND REMOVE IT.
            file.remove( fname )
            fcount = fcount + 1
           '---------------
           Continue_next:
           '---------------
            ON ERROR goto 0
            statusbar.robot()
           NEXT
          NEXT
          statusbar.clear()
           
          trace.writeln( ltrim(str( fcount )) + " '$$' files deleted" )
          Del_dollar = ltrim(str(fcount))
          END FUNCTION
          Disclaimers:

          1. I'm not absolutely positive that there is no need to include the new v8/9 "Application Data" folders but so far I haven't seen any issues there on my system. If anyone finds a reason to add those, please let me know.

          2. It's not the best coding technique but it works so I'm not messing with it. (We all had to start somewhere and I've learned a lot since 2002.)

            Re: temporary mpx files

            After searching the archives again I found a function A5_ForceCloseTables() which closes all tables that do not have an open window, I think this solves my problem

            Thanks to all who responded
