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.

Use variable in Xdialog?

  • Use variable in Xdialog?

    I have function (as an xdialog) that displays a list of choices. In the line the defines the width and number of rows:

    [%hv%.41,10chc^#in_list!lst_*];

    (where there are 10 rows in this example), I would like to replace the 10 with a variable, so I could prompt for the number of rows when running the function. (When developing an app, I start out with a few reports, and get more and more as time goes on. It would be nice to change the length of the list by simply changing the parameter in the function).

    Can this be done??

    Bill,

    Have a look at this script and see if you can pick out what you want from this. It will show all the reports in an app, which is a variable count.

      RE: Use variable in Xdialog?

      Bill,

      Yes you can by creating the dialog code before you actually run UI_DLG_Box()

      With out knowing your whole script I can only give you the edited versionb of it, but its something like this:

      DIM dlg as C
      DIM dlg_title as C
      DIM rows as N

      dlg_title = "Bills Dlg List Example"
      rows = 20 'gives you 20 rows in your list box
      Dlg = ""%str%
      ;
      This is Bills list box;;
      %str%

      dlg = Dlg + chr(13) + "[%hv%.41," + rows + "chc^#in_list!lst_*];;;" + ""*12,1OK!OK" "12,1Cancel!CANCEL""

      Bills_dlg = ui_dlg_box(dlg_title,dlg)

      Hope this helps ..

      Scott

        RE: Use variable in Xdialog?

        Hi Scott,

        Tried to use "+V_Rows+" in my script above, no joy!

        How would make use of the Number prompted for in the variable V_Rows?

        'Prompt for a number and store result in a variable called 'V_Rows'.

        dim prmpt_title as c
        dim prmpt_prompt as c
        dim prmpt_default as c

        prmpt_title = "Get Number Of Rows"
        prmpt_prompt = "Enter a Number"
        prmpt_default = "1"

        DIM SHARED V_Rows AS C

        V_Rows = ui_get_number(prmpt_title,prmpt_prompt,prmpt_default)

          RE: Use variable in Xdialog?

          scott is correct.

          one of the most powerful aspects of xdialog is that the dialog body, and dialog event (i.e. the second and third arguments of the ui_dlg_box() and ui_modeless_dlg_box() commands are STRINGS!!).

          this means that you can use any xbasic that you want to manipulate these strings BEFORE you instantiate the Xdialog.

          as you know, much of the user interface of a5 itself is written using xbasic/xdialog, and we use this technique extensively.
