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.

    How to Carry Field Values From one Dialog to Another?

    I have a WWWeb navigaton menu with seven Dialog items, no database. I want to ask for certain values, like Age, Sex, Height, Weight, on the first dialog, and then populate those fields automatically, on other dialogs.

    I made the controls Session variables, on the first dialog.
    I created code, in the "Initialize" event, of the next dialog:

    if eval_valid("session.Age") = .t. then
    CurrentForm.Controls.Age.value = session.Age
    else CurrentForm.Controls.Age.value = 0
    end if

    I published all the files to my Local Webroot.

    NOTHING carries over! What am I doing wrong?

    Re: How to Carry Field Values From one Dialog to Another?

    Didn't test but that should work. On the initial dialog, you would need to press the normal submit button to submit the dialog, otherwise the values would not be saved to session variables. That is, an Advanced Button would not work. You might test to see if your session variables are being created at all. I would put all of them in an A5W page and then have my dialog call that page in the AfterValidate event and see if the values change.

      I've attached the component under discussion. One of the session variables is calculated in a field expression. Age and Sex are just filled in by the user. I have been pressing the "Submit" button, to no avail.

      How do you make the "Reset" button do anything?


        Re: How to Carry Field Values From one Dialog to Another?

        I know you need this for a presentation today. But after more than an hour, I still don't see what's causing the trouble, and I will not be able to have an answer for you before the end of the day. Maybe someone else will see it.


          Re: How to Carry Field Values From one Dialog to Another?

          Its the Precalculate setting in layout options. Turn it off and it works. But what you can do is:

          - leave precalc on since you need it
          - change Age to Local scope
          - add the following to Aftervalidate
          session.age = currentform.controls.age.value

          that'll give you your value in the session variable.

          I also needed to turn off validation for age, save, then turn it back on, save.
