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.

    Use calculation below to calculate age in months on input of birth date in "DOB" field -writes to a field for age in months.
    12*(YEAR(SHOW_DATE)-YEAR(DOB))+MONTH(SHOW_DATE)-MONTH(DOB)+IF(DAY(DOB)>=DAY(SHOW_DATE),1,0)

    Need the age in months converted to years,months,days to be written in another field called "aginyears"
    or
    With input of birth date in DOB field to calclulate age in years,months,days for field "aginyears"

    Any help would be appreciated

    Re: convert age in months to years,months,days

    Jim,

    This to start you off.

    Age=date()-DOB
    months=age*12

    You will need to make some adjustment between the number of months in the DOB year and number of months to date in the current year.

        First off Thanks Mr.Hubert for your reply.

        Mr. Gandri,
        Your code was exactly what I was looking for. I knew that I had seen on the message board but was unable to find it. Thanks!

        However now upon executing "New Record" (a button on menu for adding a new animal) the dialog box for the year,month pops up.
        Can not get past it to enter information about the animal.
        Can you help?
        Jim

            Re: convert age in months to years,months,days

            Mr. Gandhi,
            Again thanks for your help. I have implemented the code into my application and it works.
            I am having a little difficulty with making the script run like I would like to have it run.
            Attached is my application.
            Open main menu-open Llamas.
            On input of llama birth date-would like for it to populate the code with startdate (which is "DOB" field) and enddate (which has obtained from "show_date" field ) and then display age in years, month,days.
            This would do the task in one operation as opposed to two as I now have.

            Please understand that I am a novice at this and sometimes may not use the correct terminology.

              I will redo your database and send back.
              in the meantime
              take a look at the second video below the code and study the code. I revised earlier after rereading your post.
              you have copied the xdialog method, but I am using function and calling the function from on change event on your show_date field.
              also I will be changing your age_in_years from numeric to character to show the string.
              it will take about 20 minutes or so then I will upload the zipped file.
              thanks for reading

                Re: convert age in months to years,months,days

                okay
                I did some modifications to the table and the form.
                I changed the yearsold to character field, I changed the animal_age from calculated field to user entered, I removed the button to calculate the age, I removed the event firing the xdialog on canedit event of the show_date. I changed the tab order to suit me, that is not my advice for you to change.

                here are the two videos

                work looks very good to me.

                  Re: convert age in months to years,months,days

                  Again Mr. Gandhi thank you for your input.
                  I have changed the tab order to suit a better flow of data input.
                  Changed the show_date so that it defaults to the last entry. When using the application the show _date will stay the same until you start a new set of show data for a different show. By changing to default you are not having to input show_date for every new animal entered. The only thing I can not solve is upon changing the DOB (because of wrong input by user-typo) for an animal already in the data base the code will not recalculate the age. I have tried several different things-never recalculates age.

                    Re: convert age in months to years,months,days

                    because the show_date does not change the onChange event will not fire if attached to that field. you could on the otherhand attach to the dob of the animal field on change event then it should calculate when you enter the dob.

                        if you think, you may need to change the show_date periodically on the data then you can have same function fire onChange event of that field too.
                        you can modify the code for the function to skip calculation if either of the fields is empty. if you do that then you can keep the current tab order.

                          The tab order in each example works fine. I never gave it a though that the tab order effected running the code. Learned something the last few days.
                          This message board and it's advanced "Certified Alphaholic" are amazing.
                          Again thinks again.
