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.

  • Outliner

    Attached is an outliner that runs of the web app server (WAS). Since grids can be displayed and run in an xdialog, and since an xdialog can be embedded in a form, you can easily run this sample on the desktop, as well. Mauricio Maisterrena gets credit for this outline as per this thread:

    http://msgboard.alphasoftware.com/al....php?t=81075#6

    I am posting this sample as I have been using "Maurico's" idea, since ver 5 on the desktop using the same basic principal in an embedded browse - essentially a flat file with recursive references. In the desktop version (which I am not posting here) you only see one outline level at a time, as drilling down or navigating up the "tree" essentially runs a simple query. Here, on this grid version, you can view the outline tree normally. As what is posted here is a very simple outline sample, it lacks the typical cut & paste features one would expect in an outliner. Such features would require some coding to make this outliner truly functional. It should also be noted that a database version of an outliner has some limitations in terms of ordering. In typical string-based outliners, you can promote/demote items on a given level, in a database, the order is fixed on a given field or expression. There are ways around this but it gets messy.

    For a discussion of what prompted this post, see:

    http://msgboard.alphasoftware.com/al...ad.php?t=84514

    Note: If you are not conversant with the web side of Alpha, after you have unzipped and opened this sample application, open the web control panel from the regular controlpanel's toolbar. Make sure to turn on the application server - if you see a red icon in the toolbar, click it to green. In the web controlpanel, select "all files" and doubleclick "outliner". Select the "live preview" tab to run. At this point you can also click on whatever browser icons are displayed at the bottom of the live preview tab to run the app in your browser. As I said in one of the threads, a person skilled w. HTML and the WAS could make this look much nicer than the relativity crude appearance that it has currently.

    Re: Outliner - A5 V10.5 RC6 Build 3456 (ROW Expander)

    What should be the override settings for an outliner, because you would be referencing the same grid in Row Expander.

    I tried

    _gridFilter = " "
    flagMustRecalcGridLayout = .t.

    Only once it seemed to work, and after reloading the grid, it does not work.

    The Row Expander seems to still pick up the base filter, which restricts the first set of data displayed.

    Any way of overriding the base filter in the grid linked in the Row Expander.

    Thanks,
    Srini

      The sample should work. Look at the row expander settings.

        Re: Outliner - A5 V10.5 RC6 Build 3456 (ROW Expander)

        Thanks for the quick reply.

        I have MS SqlServer as the backend and I am using a SqlServer Database. I tried doing the same thing with an Alpha Five database and it works.

        I have been trying various combinations with resetting the base filter for an Sql Server database.

        Obviously I am missing something.

        Any pointers would be much appreciated

        Thanks,
        Srini
