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.

    Can't open new record

    A nursing home database containing tables for services such as doctors, dentists, opticians etc. (15 altogether) has been working perfectly for several years. Each table has a form attached to it with buttons for moving through records and opening a new one.
    Suddenly, without obvious cause, one of the forms (doctors) refuses to open a new record; instead it duplicates the record which happens to be active at the moment. All the other 14 forms (which are structured in exactly the same way) continue to work properly as before.
    The button concerned has the following script attached to it:
    parentform.commit()
    parent.allow_change(.T.)
    parent.new_record()
    END
    Trying to open a new record using the relevant toolbar provided by the Alpha program produces the same result - duplication of a record instead of a new blank one.
    Two machines are affected, one using plain Alpha4 v5 without the major update patch and Windows XP Pro; the other has versions 4.5 and 5 on it with a slightly earlier version of Windows XP Pro. All behave in the same manner which would seem to indicate that the problem lies with the application database.
    We haven't switched to using Alpha5 v5 for the nursing home as this version has other problems associated with it which haven't been sorted out yet. The machines are not networked: one is the nursing home's and the other is mine (the developer) which I update from their data as an additional backup and also to check out further developments.

    Would much appreciate any help all you knowledgable souls out there can offer.

    Thanks,
    Dennis

    RE: Can't open new record

    Dennis:

    What happens when you try to enter a new record in the default browse? I'm thinking things might be more obvious to you without the form's overhead.

    I first thought that you might have a auto-increment field that was filled to capacity but that would have thrown an error message. Be sure that your table's index in the form is correct and that no query is currently attached when the new record is attempted.

    Maybe others have experience this and have some ideas. I did try to replicate your problem using your script with a home-made form button and couldn't.

    Let us know more.

      Ken,
      Thanks for your reply.
      I meant to mention in my first e-mail that I could still use the default browse to enter a new record. (Thank heavens! otherwise the nursing home couldn't update its database when a new GP appears on the scene).
      There is no auto-increment for this table; indexing is exactly as it always has been and has been rebuilt several times. No query has been active when trying to enter a new record.
      As mentioned before, there are 15 other tables and associated forms with an identical structure which have been in use for as long as the offending one and all still continue to operate without fail.
      I feel the fact that duplication of the active record occurs instead of a new one being created should give some clue to the problem but I haven't been able to deduce it.

      Thanks for your interest,
      Dennis

        Dennis:

        My next step - if the problem was mine - would be to create another form and see if the problem still exists in the new form. Perhaps Alpha's behind-the-scene's code for your form has become corrupted. You might do this for a test using the default form and pasting the bad form's button to it. You don't have to save it to test. If this works, then bite the bullet and delete the existing form you've been using and build a replacement with the same name.

        Others on this board may have more ideas.

          RE: Can't open new record

          Ken,
          Haven't yet had time to rebuild the form as you suggest but shall be doing so shortly.

          I found a version of the nursing home data on one of my computers which hadn't been updated since December 2003 and this did not show the doctor new record problem.

          I transferred the data to a zip disk and checked it out on my other two computers which between them have: A5 V4.03 build 216, A5 V4.5 build 266 and A5 V5 build 1506 on them.

          All worked perfectly when opening a new record from the form. So the problem lies with the data and is fairly recent as a new record on the form in question was opened about 2 months ago. Could it be a data dictionary has been corrupted? Rebuilding the form as you suggest might well cure the problem if not revealing why. Will let you know the outcome.

          Many thanks for your assistance.

            Dennis:

            I think we've found the problem. Others on this board and the V5 board suggest that changing a 4.x form in v5 can definitely bugger the works. Generally speaking, if you change a v4 form in v5 it is very likely WON'T work properly when you take it back to v4. I didn't search before responding here but I suggest that you might..... I just know that I saw that somewhere.

            Good luck

              Thanks for the tip. I'll see if I can find the reference.

              And thanks for your help,
