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.

    Copy Table

    I want to copy a table but indexed properly. Then I want to delete some records and save without the deleted records. How is this done?

    Re: Copy Table

    I do this all the time.

    Simply open the table in "edit" mode, then save it to a different name.

    So for example if the original table is called customers.dbf, open it in edit mode, then save it as "customers2.dbf" or something like that. Then you'll have two identical tables. At that point you can make changes to either one, and have the other as a backup.

    I often do this when I am making changes to a table structure, just in case something goes wrong.

    Incidentally, you don't have to "save" after deleting records. That happens automatically, although sometimes the table will ask you if you "are sure" when you try to close out of it.

      That doesn't work for me..

      If I open AlphaSports customer table in design mode (ie open to edit structure) and save as customer2, I get a new table but it's empty of any data.

      Or are you doing something different than that?

      If I right click on the table, utilities, duplicate, I get 4 choices to make (records, indexes, Dictionary, Field Rules), and can save as another name.. and I get a new table with the options I chosen.

      Or I can make a copy operation to target a new table... and get a mirror of the original table.

        Re: Copy Table

        Absolutely correct Al, my apologies.

        I had the wrong operation in mind. I've copied tables both ways and kept the indexes, but as you said, using the method I suggested does not copy the data as well.

        The other method that I use (and you just mentioned it), is to right click on the table, click "utilities," then click "duplicate."

        Just like Al said, that will maintain the data and the indexes, if you opt to retain them.

        Sorry for the confusion.

            When you choose the "duplicate" funtion, it will ask you if you wish to copy the indexes.

                Is that not happening when you duplicate it?

                  Re: Copy Table

                  You don't need the records to be in order to use auto increment.

                  Alpha builds an index to find the largest value and increments that value for the new record.

                  All you do is click the option in field rules. And save..


                  btw - you can control the order that data is written by using the copy operation, but not with the duplicate utility.

                    Re: Copy Table

                    Al......How do you get to the copy operation? Right now the table is disorganized: I have to index on 3 fields. If I could save the indexed table and then add a record number field, specify an auto increment field rule and then apply the field rule I would then be able to index on record number..........Dick

                      There is more to this issue than the table is disorganized.

                      I sent you an email, please contact me.
