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.

    Form.view (formname'"Dialog") leaves fil

    I have found that if you use
    form.view (formname,"Dialog") to load a form as a Dialog that after the Dialog returns to the calling form the files it used are left open
    ie: if you do
    ? table.enum_open ("F"+crlf())
    You will see table handles are still opened

    Interestingly if you open form with
    form.dialog("Table Name")
    You do not get the same problem

    Any comments?

    RE: Form.view (formname'

    Does the script which calls the dialog form also close it on return? If not check the docs for information on "closing a dialog box", cause I think it must. Closing the called form with the system 'X' or a close form button will not close the form, it just hides it. An idiosyncracy of forms opened in dialog mode. -- tom

      Yes it does close the form - but the files still stay open
      The work around works Ok - but I thought it was worth mentioning

      There is a reference in help to having to close tables using zoom_to_record function - so I am guesssing the form.view works in much the same way.

      ie:

      x = topparent.zoom_to_record("customer_detail", "dialog")
      x.pointer.close()

      Its one of those things you find out the hard way when your application starts crashing after it has been in use for a while

        RE: Form.view (formname'

        I have got to the bottom of this and it is seems the way that Alpha intended it to be. ie: You can call using the "dialog" option , which suspends operation until form is closed. On return you can read the field values directly off the form - but you must then close it with a {frm}.close() command as it is only hidden.

        This is actually in the help file for form.show() - but not covered under form.view

          Exactly. That's what I was referencing in my earlier response. Don't feel too badly. Many of us have hit the same wall (myself more than once!) on the way to understanding, finally, that when forms are opened as dialogs they require special handling. --tom
