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.

  • Not Found for a find

    I am trying to create a message box that pops up when a find() comes up empty. The field in question is a numeric userid field. The find() command has an annoying tendency to give you the next closest number when the number searched for cannt be found. Any solutions out there?

    RE: Not Found for a find

    Take a look at .fetch_find()

    The function returns the record number on an exact match or a negative number if a closest match is encountered.

    You can use this function in the background and resynch your form data if it is successful or provide an alternate message for the user on a mis-match.

    There are a few examples of the code in the manual.

      it would be so nice if this board didn't eat special characters :)

      That was supposed to be "tbl".fetch_find()

        You could probably do something with key_exist which returns .t. if it does and .f. if the key does not exist. So you could do something along the lines of

        set the index you want
        if .not.KEY_EXIST( "IndexName", "value to search for" )
        ui_msg_box(etc etc
        else
        parentform.find("value to search for")
        end if

        Im just typing this so you probably will have to work the syntax a bit.

          The key_exists worked out really well thanks so much for the heads up but it took a while for me to discover that I had to transform my numeric field value into character. I wish the documentation could be more thorough. I rememember with fondness the docs I go in my Foxpro and R:Base days, sigh. Anyway I really feel that I am getting more comfortable with this language.

          Cheers
