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.

  • Update a country

    I wondered if anyone can point me to a tutorial which shows how to update a contact / country field

    EG I have a contacts table with a countryID field and a country table with a countryID field.

    When I change the countryID in the contacts field I want the new country to show in contacts table

    CountryId is a numeric field.
    Country is a char

    I tried with mapped tables but somehow cannot get the contacts file to be updated.
    Obviously I am missing something basic!
    Thank you, John

    Re: Update a country

    Where are you? On a grid viewing the contacts table? If so, you could make a dropdown control reading the contents of the countries table. The only problem with that is if you have 10 records and 100+ countries, you get 1000+ lines of HTML that have to be created, to create a list for each Grid record. But that will work.

    What are mapped tables? Do you mean you created a View in the Grid, not sure where you are.

      Use a table lookup.

            Re: Update a country

            Thanks Peter
            I was hoping to select a new country from a drop down box and update the record so that the new country was updated into that record.
            I was also wishing to do that in the Detail View.

              If you use a dropdown, you can only affect the dropdown field. It cannot 'update' a second field.

              A Lookup will allow you to select a value for the lookup field AND update one or more fields on the page, all using Mapping in the Lookup definition.

              So the easy way is to use a Lookup.

              A more complex way is to use the dropdown to get the ID (you can have it actually display the ID or the Name, but the ID is being recorded in the table). Then, since you have updated your field with the ID, you can use Grid Events to also update the table with the country name when (and only when) you click submit. There is no magic mapping here, your event code would do a lookup to the country table and use the ID that you just selected to get the country name. It would look similar to this:

              datasubmitted.countryname = lookupc("F",countryid,"countryname","[PathAlias.ADB_Path]\countries","id")

                Thank you very much for the help.
                After reading the support article through a few times I gradually got the idea!
                Easy when you know how!
