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.

  • Object is not defined

    I've been getting this error a lot lately in different scenarios.

    Script:OnInit line:43
    varP_SoundCards_Update = :Form.view(layout_name,"dialog")
    Object is not defined.

    In the OnInit of the main form, I place an action to open a form, this 2nd form runs some actions and then close, leaving the main form open. (the 2nd form is "SoundCards_Update")
    But each time the "open form" action is run I get the above error. I've deleted it and redefine is several times, i get the same error.

    Help Please.

    It would help to see more of the script - did you DIM layout_name as c first and populate it with the form name?

      Re: Object is not defined

      I used Action Script like I've always done, When I convert it to Xbasic, this is what it looks like.

      'Open a Form or Browse layout, displaying all, or selected records in the layout.

      DIM Shared varP_SoundCards_Update as P
      DIM layout_name as c
      layout_name = "SoundCards_Update"
      varP_SoundCards_Update = :Form.view(layout_name,"dialog")

      'After the user closes the dialog form, the form remains in memory and the script
      'continues with the next command.

      'You can insert any code here that you want to execute before the dialog form (which is now
      'hidden) is removed from memory with the .close() command.
      'The code that you insert here can refer to the form using the pointer variable, varP_SoundCards_Update

      if is_object(varP_SoundCards_Update) = .t. then
      end if

        Nigel, you may be asking the onInit event of your form to do too much work. You might try moving the script to the OnActivate event for the form, and set a flag to prevent it from running again until that form is closed. -- tom

          Re: Object is not defined

          I moved it to the OnActivate of the main form, I got the same error message.
          I then tried it in the Autoexec script, this time the error was worded differently but it said the same thing.
          It seems there's something wrong with the action itself.

            Re: Object is not defined

            I don't see anything amiss in the xbasic you've shown. How about posting a sample database here with instructions for us to follow to see the glitch?

              DIM Shared varP_SoundCards_Update as P
              if is_object(varP_SoundCards_Update) = .t. then
              varP_SoundCards_Update is NOT an object.. it's a pointer
              SoundCards_Update is an object, once opened.

              That said.. the if() statement will always be false.. but shouldn't cause an error..
              At what point are you getting the error.

              If the user closes the form, it's closed.. it doesn't remain in memory.

                He's opening the called form "as dialog". It will remain hidden and "open" even when the user closes it from the UI. The calling script must close it.

                The function "is_object()" can take either an object address or a pointer as an argument.

                  Evidently not..or it might be the new brand of coffee..

                  The dialog form, when closed by the user, will be hidden from view & remains in memory.

                  Instead of:
                  if is_object(varP_SoundCards_Update) = .t. then
                  end if
                  if is_object(SoundCards_Update) = .t. then
                  end if
                  and see if the error goes away..
                  I am thinking the pointer is an object as long as the form is open, not just in memory .. and there is a difference.
