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.

Speed tip

  • Speed tip

    Here is a speed tip that you may or may not be aware of and you may or may not find useful.

    I have form loaded with calculations (156 to be precise). These calculations arrive at about thirty total calculations displayed on the form depending on which query is being run by a choice of buttons. The form was taking up to 2 minutes to load and view, and I happily accepted this as the norm because of the heavy work load of calcs.

    However, I found that if I set a filter in the form properties to limit the form load to 1 record, the form opens almost instantly. So I have now set a variable on the button that opens the form that gives me a field to filter on and that I know will always be present and unique to one record. I then used this variable in the form's filter properties. On the form's onit event I run a lightning query script that shows all desired records and the form view is now almost instantaneous.

    Hope this helps

    Another approach is instead of using calc fields, put the calc formulas in xbasic on a button - no load overhead.

        Peter,

        I don't fancy placing 156 calculations in a script.

        Martin,

        I have used 'name=var->this_name' as a filter. The variable is set on the button of the calling form and sets first name+last name expression. It can be anything provided it limits the filter to one record.

            Have you tried setting the calculations at table or set level I.E. as global calculations. I am not sure if this will help but it may be worth a try and it is a practise I use consistently.
            Let us know how you get on.

              I don't know about that. I used to have a bunch of calculated fields on the set level doing totals, and opening the form and other actions took forever. I finally moved the time-consuming, resource-exhausting calcs to a button and all was well.
