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.

    Hi Mike,

    Ira?? :)
    It doesn't really change much, but the global variables are the avenue to problems down the road where various thing change values at the wrong time. The correct way here is to pass a pointer and table name (if more than 1 similar table could be used) around that has all the variables as a property and is returned with the updated values

    Returning the pointer allows isolating failures in code to sections of code within the application.

    My entire CSDA Code Utility has only 1 or 2 global variables that are pointers with a lot of different properties. There are no interference from anywhere else because there is no sharing of variables with other application (because they would need to reference them as a property of the pointer).

    On the other hand, name a global variable with name Temp or Tmp or cmd and see how fast things start failing!

      Had the code been inside a function, the table would (well normally, anyhow) be closed upon exiting the function. The problem would never been even noticed! (However, it's good practice to always close whatever you opened when you are done with it.)

          cal,

          Been on your site. You are amazing. Had plans to purchase your utility until something came up and, no!, it is not your pricing. I think it is very cheap. We will see in a few days.

          Anybody building a monetary type app would need those payment and other functions, but they need to be in an aex and well protected from tinkering.
