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.

    Re: Problem with Topparent.find(var_key)

    Your references to "topparent.cancel()" and the fact that you are "trying to preserve the look-and-feel of the original program" make me wonder - are you perhaps in Enter mode when all this starts? If so, that would be a whole different situation. I would not expect a topparent.find() to work while in either Enter or Change mode.

    I also get the impression that you are trying to "look something up in a different record" and are just going to that record to get the info. If that's the case, there is probably a better way to do it.

    If you can't upload something for us to work with, please give us the full story of where you are starting from and what you are trying to accomplish. Sometimes a question like, "How do I get the key to turn in my car?" isn't enough. The answer will be completely different if you are trying to start the engine, open the door, or open the trunk. Then, when we find out that you just bought an old Model-T and are trying to start the engine, we will probably suggest other things besides looking for a place to put the key.

      Cal,
      Like where to put the crank? ;)

      KDM this is where the script library comes in handy for keeping little snippets of xbasic code that you may want to put in many of your scripts - like testing the form's mode & committing a record first, etc.

        You are right. The form is put in ENTER mode when it is opened.

        What the form does is accept a record key in field # 1 and then try to read the record if it exists, display its contents and allow the user to change the contents. The user is supposed to enter the value of a record key in field #E 1 and press <Enter>. If the record exists, the contents are displayed and the user can then change the contents. If the record does not exist, the user can proceed to enter new data and save the data as a new record.

        I managed to eliminate most of the blinking by using a combination of conditional objects and hide/show objects.

        Any better ideas ?

          KDM, I think it's asking for trouble to begin a new record just to collect input from the user. There are too many ways the incomplete record will or can be saved. This leads to lots of bad data in your table. A much better approach would be to capture the input using a custom xdialog box, and then let your script validate the input from the user before opening the form and fetching the desired record.

            Problem with Topparent.find()

            This oddity occurs in version 10, and probably in version 11 too!

            topparent.find(var_key_target) only works when var_key_target value is of type N
            ~And changing the code to topparent.find(eval(var_key_target)) works even though the record's fields index (the record I'm navigating to) is of type C.

            Example:
            Auto increment field ("being looked for") is of type character (and displays as 00001, 00002, 00003) in table. (unique index on field is of type C)
            Yet you have to pass a numeric value which presumably evals to 2 instead of 00002 in order for the .find method to go to work and go to (find) the correct record on the form.

            Note: Without adding the eval(), the debug pops up with error "conflicting data types" The only thing I can think of here is that the .find method is somehow converting all record indexes / fields into some type of numeric representation for searching?

            I'm guessing this is not efficient, and there must be another way to specify a specific key to use in the search? I know I could create a query, and filter for the result on the form, but but I want to keep all records available in the record navigation bar. (Kind of like how the super-control dropdown browse can be used to search for / select a particular invoice on a form.)

            The only other way (thus far) that I have found is to apply a filter (query) to the form, and immediately afterwards issue the form.show_all() method. ~ Is there a better method without using the super-control?

            for example (this is "pseudo-pseudo code", and won't work): topparent.find_by_key(key_name,field_type,key_value)???
