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.

  • post operation

    I installed a button for users to run stored post operations. I would like to allow the user to input a variable to be used by a stream of the post operations, but do not seem to pass a globel variable from my form screen to the post operations. Any suggestions?
    Thanks

    RE: post operation

    Charlie:

    On what action are you declaring the global variable?

    You need to declare it, perhaps in the autoexec script, first as such:

    dim global thevariablename as c

    where c is a charater
    where n is a numeric
    etc...

    OR:

    Are you declaring it on the form itself?

    At any rate when and if you have done this, place a value in the variable, and go to the interactive tab in the code editor. Type in

    ?thevariablename

    If the value you typed in comes back, you are collecting the variable properly.

    If an error comes back, you have not properly declared the variable.

    Once you get the variable working properly, it should be available to use anywhere within Alpha until you close the database.

    Remember to use the variable by preceding it with

    var->thevariablename

    in operations like the post you are attempting.

    Hope this helps!

      RE: post operation

      Charlie, pls post a working model here, with a description, step by step, showing which forms and operations are involved.

      If you're simply trying to post a single value, stored in a variable, to records in the table, try a saved Update operation instead of a saved Post operation.

      If you're trying to use the variable in an expression defined in the saved Post operation, we need to see your complete database to see the context in which it's running.

          RE: post operation

          Charlie,

          I took a look. I'm confused about your goal.

          Your set has three tables. You are trying to update a field in the child table, based on values found in the grandchild table. However, the link between child and grandchild is not one to one, it's one to many, and you have more than one grandchild record for each child record. My question is this: which of the grandchild records do you want to pull values from to update the linked child table record? Since there's more than one, I'm confused. Maybe it would be best if you simply describe, in words, what it is you're attempting.

            I am sorry for the confusion. I will try to clearify it.
            In my actual data base, the 99+% of child records have only one grandchild record. I will need one more check in my logic that checks for "once old" always old.

            My main goal is to get a variable passed from a form to a run operation, as I have several other operations that I would like to handle the same way.

            Thanks again

            Charlie

              Charlie,

              I could not pass a variable to the operations genie.

              However, it's relatively easy to:

              1) build the operation with the genie, using a constant value;

              2) record the script (low level)

              3) modify the script to use a global variable instead of the constant.

              Here's an example which uses your Begin form to update the value of 'Retention_Days' in all Table-B records.
