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.

    Thanks, Gregg. I'll give it a whirl.

      I know you already have a solution for this, but in case you, or anyone else, is wondering about an alternate method (a bit less programming and what there is can all be done in javascript):

      1. You have your list with a search form
      2. in the search form is all the fields you would want to validate
      3. When they are entering a new record they actually enter the data into the search fields
      4. Then you have a custom submit button which does a search and determines the number of records returned (easily done in javascript)
      5. if a record already exists then it pulls that one up for editing
      6. if not it creates a new record and inserts the search form data into the fields

      Just a thought. Happy coding.

        There is always the idea that you could have a separate component that can perform a merge of possible duplicates, marking them as NOT a duplicate if needed. Might be a bit more work though in the thought process to create but will certainly give users more control over their data.
        Show both records in separate lists. Correct one then delete the other could be a simply idea - all manual data entry ensuring the code doesn't miss something - or - overwrite something unintentionally.

          For the most part in my application, every once in a awhile there will be a duplicate customer. Often the phone number is the same, so when entering it a drop down of selections based on a lookup can help confirm a possible. I also have another drop down that you can do a last name check. I leave it up to the data entry person to check on their own work with the ability to simply pick from an existing customer if they find a match during entry.

            Another resurrected post from me... can you tell I'm nearing a deadline?

            Here is a portion of my code:

            duplookup = sql_lookup_multi(cn,"records","last_name = :last and (first_name in (:first,:spouse) or spouse in (:first,:spouse))","first_name,last_name,spouse,address",argsUpdate)
            dim first as c
            dim last as c
            dim spouse as c
            dim address as c
            first = duplookup.first_name
            last = duplookup.last_name
            spouse = duplookup.spouse
            address = duplookup.address
            if dupCount >= 1
            js = <<%str%
            var title = 'Duplicate Found';
            var html = '<p>There is a record with this name already. Do you want to enter it anyway?</p>';
            var type = 'yn';
            var onClose = function (btn) {
            if (btn == 'yes') {
            // save their work then close the window
            } else if (btn == 'no') {
            // close the window
            } else {
            // cancel - do nothing
            A5.msgBox.buttons.yes = {html: 'Yes', className: 'msgbtnyes'};
   = {html: 'No', className: 'msgbtnno'};
  , html, type, onClose);
            Is there a way to call the variables (first, last, spouse, address) in the message box? So the user is shown "There is a record with this name already. (NAME, ADDRESS) Do you want to enter it anyway?"

            I'm not sure how to use variables in the <<%str% format.

              The strtrani() function is your bestest friend for that.
              Format the string the way you want, putting the desired
              elements between <>. example : js = strtran(js,"<first>",duplookup.first_name)
     is a great site to test and share sql code
