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.

  • Posting Problem

    I am a kidney patient, and have been for the last 24 years (21 of which were at home on a kidney dialysis machine having had a transplant since). Although a have computer experience, I am not a programmer, however about 8-10 years ago I wrote a database for the Renal technicians for patients and their associated kidney machines in Alpha4v4 (DOS). This worked well until a new PC was required with Windows 2000. I have now been forced to rewrite this with all the new functions\facilities of Alpha 5 in Windows. My problem is as follows:-
    I have a Primary table called machines and a child table called patients as a one to one. These are Dialysis patients who are linked to a single coded kidney dialysis machine. The link field is called machine code, and both tables have a field called surname. I want to be able to either change the machine code to another patient or the patient surname to another machine using the post function on editing either table. It could be the machine has moved to the workshop for repair, or the patient has died or had a transplant. The machine then needs to then be attached to another record\patient etc. The machine table also has further child tables attached, repairs to each machine on a one to many basis etc. Where as, the patient (child) table has water samples on one to many (this relates to samples at their home and not the machine). I originally had these tables all in one set, and have tried since with them split into separate machine and patients.
    DO I HAVE A PROBLEM WITH THE LINK FIELDS OR IS THERE AN EASY WAY TO MAKE THIS POSTING ROUTINE WORK?

    Ian,

    First - my prayers are with you for what you are going through. Hope you feel better.

    Second, you could zip your application and post it here, so I could take a look at it for you.

    To answer your question, there's no one real way to handle this. It all depends on the application and how you want to do things. Rather than use "Post" within the fields rules, because it has some serious problems, I and others tend to opt for a coded routine, that runs when you save the record or close out of the form. By using this method you can be assured of getting what you want, when you want it.

    If your having problems, I'm sure we can help you. Best thing is to post the zip file and then tell us what you want to do.

      Ian,

      Give this some thought. It appears to me that your patients ought to be a single table. Add a field to the patients table called Machine and then use the parent table as a lookup table to fill in the machine field.

      Whenever a patient's machine changes, simply get the new machine via the lookup. Multiple patients could still use the smae machine.

      Perhaps there are other factors in your database that might prevent this but based on your request, that's what I'd try.

      Knowing what you can achieve will not become reality until you imagine and explore.

        Many thanks for your reply.

        I have attached my test files zipped for further advice. If you look at the machine & patient form - having tested it with both a full set called rsch & then a separate set, called machine & patient. The problem is trying to obtain a linked new patient, to a new machine (on a one to one basis), but display (post) the surname & machine code onto each form. i.e. patient 1 has now machine A and patient 2 has what was originally in the workshop or from another patient (may even be patient 1).

        I hope you can understand this, and look forward to your reply.

        Kind regards

        Ian
