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.

    Date fields European style Question

    Hello,

    I still am confused what to do with date fields in Search.
    In my tables I use the European date format (dd-mm-yy). Windows is installed that way, too.

    When using the Date Picker, and define dd-mm-yy, I get no results.

    When using the Drop Down box, there's no way to tell A5 that it should look for dd-mm-yy format. No date will be found.

    When using Textbox and no display format, A5 finds nothing. If I use Display Format = time("dd-MM-yy","value"), it finds nothing either. Should I fill Display Unformat? If yes, what do I enter there? I've seen an example somewhere, but I cannot find it again.

    If I search in a date field, can I also find a specific month or year? How?

    Working with date fields can be tricky because of the different format from US to European. The date picker returns a character value that must be converted to a date value, and this is where it is tricky. All dates have to end up in the same format, which in your case would be dd- mm-yy.

    One way to handle this is to take the character string, parse it to separate elememts for day - month - year and then use the date functions to "build" a new date in your format. For example, you can use substr() to get a character value for day, month, and year. I may end up with

    vday = "25"
    vmonth = "9"
    vyear = "2004"

    Then I use the date functions to "build" the date. Since they will use your local format, this eliminates the formating issue.

    newdate = addmonths(ctod("01/01/"+alltrim(vyear)+""),val(vmonth)) + val(vday) - 1

    This will work regardless of the local date format since you start at Jan 1, which is formated the same for each convention.

    Once you have a valid date, you can use cyear() , month() or many of the other date functions to create a value for searching.

      Hi Jerry,

      thanks for your answer. I'm sure this does the job, but I have the feeling that the makers of Alpha Five, if they like their products to be used in Europe, will find a more simple way for dummies like me. Neverhteless I'll give it a try...

        Rene,

        The date picker format is in the latest build. Please see attachment of how to change the result to European format. I have used the Flowers sample to test.

        Good Luck

          Keith,

          Thanks for your contribution. I was already aware of that. The problem seems to be that somewhere the formats mix up.

          Attached you'll find an example. If you open Examens.a5w you will see (I hope).

          Whatever I fill in in the search field or how I do it, I get no result. Try 12-06-04 (june, 12)

              Rene,

              I think there must be a file missing from your zip. Your web component had a link to a table that was not there.

              I did a test on one of your tables with an editable grid and a Date Picker.

              As you will see from the attached it works with no other alteration other than changing the format to dd/mm/yy in the Date Picker Properties.

              Sorry I cant help more.

              Regards

                Sorry, Keith,

                The problem is not the date picker in data grids, that works fine.
                The problem lies within the Search grid.

                I cannot search for a date, whatever way.

                  Hi Ren�,

                  Having greated a new grid with your data I now understand your problem.

                  Unfortunately I get the same result.

                  I have checked with the Alpha sample data and my own data and it works correctly.

                  Maybe someone else can take a look and see what is going wrong, I would like to know too.

                  Regards
