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.

  • Question on Alphasports Invoice Entry Form

    Hi Folks,

    A long time since I have needed to change anything on my database and I cannot remember a critical piece of information - I am hoping someone on here can help me with a suggestion.

    Anyway the problem is this:

    I have a field in my database which is a character string of 4 length similar to the field in the Alphasports example database (I think it was the Alpha Five Version 8 of the Alphasports example database - not the latest which is different) which holds sales peoples names. But I cannot remember how the field which is 4 chars long can hold the full name of the salesperson and display it correctly on the form even though it is obviously held internally as a number?

    I want to use the left() function to return the first letter of each of the names (firstname, surname) to obtain their initials, however when I use the following code:

    Left(Purchaser,1)+Left(PURCHASER,pos_from_word_number(PURCHASER,2))

    It returns numbers instead e.g. 11 not AW which I expected

    Somehow and this is the bit I cannot remember the Character 4 field PURCHASER is displaying the full name of the Purchaser on the form, but the value that is stored in the database is a number.

    I think these values are stored in a table in the format:

    Sales_person_id : Name

    100 : Alastair Whyley

    Sorry for the long post, but does this make sense to anybody?

    Check the help file topic

    "Using a coded lookup field"

    You'll probably need to retrieve the name from the lookup table using one of the lookup() functions.

      Thanks for your reply Tom, you were spot on, it was using a table lookup. Its amazing how quickly you can forget these little tricks when you aren't doing this sort of programming frequently.

        OK I have got the lookupc function to extract the name from the external table - I think, using the following:

        dim tn as C
        dim initials as C

        tn = table.filename_get("salespeople")

        initials=trim(lookupc("C","Purchaser","salespeople->Name",tn,"Sales_Person_Id"))

        This returns a persons full name as a string e.g.:

        "Alastair Whyley"

          Well, I thought the above worked but when I tested it, it doesn't and I cannot see where I am going wrong. The help file on this command is not actually very helpful to me.

          lookupc("C","Purchaser","salespeople->Name",tn,"Sales_Person_Id")

          Can anyone see anything wrong with the above command and point me in the right direction?

          It seems to return the same name each time if I use the "C" option whereas if I use the "F" option it always responds with "", I think it is something to do with the the next part of the command but haven't had enough time recently to get any further.
