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.

    Exceptions to multiple expressions

    We have a flat file table and have run a query with multiple expressions; however, now we have exceptions to these expressions. How do we add these exceptions to a query?
    Thank you.

    RE: Exceptions to multiple expressions

    Let's say your current expression is

    fieldname1 > 0 .and. fieldname2 = "Maine"

    and you want to include records where

    fieldname3 = .F., but not exclude the previously chosen records. The expression would be

    (fieldname1 > 0 .and. fieldname2 = "Maine").or. fieldname3 = .F.

    Do you have much experience with the Boolean operators, ".and.", ".or.", ".not."?
    There can be only one.

      Helen,

      A little known but powerful feature of query by forms is that multiple forms are possible. This permits you to define one set of filter criteria on two or more forms. The effect is to join each form with 'or'.


      In a typical name and address contact list this capability would permit you to select

      All lastnames that begin with "C"

      or

      All cities that equal 'Tampa'.

      Which is something you can't do on a single QBF Form.

      See pg 38 of the User's Guide.

        Tom,

        Thanks for the information that you have given. Now we need assistance with the following:

        We have developed two complex query operations and we need to join these together into one report. What is the procedure for running these two queries into one report? We just don't know how to do this. Please help!

        Thank you so much.

          Helen,

          I suggest you start a new message thread for the next question.

          When you do, it will help if you describe your problem with the greatest possible detail and specificity.

          Describe the tables and or sets. If sets are involved describe its members and all links.

          Describe the two queries in detail, then describe h you wish to 'join them together' for your report?

          Understanding the problem is the key to the solution. Try to describe the problem assuming that none of the rest of us can see your database, or have any inkling what you are trying to accomplish (cause that's the actual situation!).
