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.

XML HELP Please!!!

  • XML HELP Please!!!

    We are under serious deadline...and we have to integrate A payment processing web service into our app.

    So the the first step...generate an XML file to send for batch processing. I have two questions.

    1. I need to generate the file from a grid ....I'm thinking the aftervalidate event.... so what command would I use?

    2. What is the proper commant to sent the information to the web service.

    This topic seems to be very light on the message boards. And the stuff I do find is way over my head....right now. Steve and Lenny are beasts.

    Any help please.

    Re: XML HELP Please!!!

    Grids don't have AfterValidate events so you mean display the data in a grid, and use a Dialog's aftervalidate event to send data from the same data-table that the grid is displaying on the screen. So, if that's the case, you can start with the code found in Code Archive (search for XML) that I wrote to output generic xml from a data-table.

    Except that a generic xml file won't do. Your payment gateway will have a very specific format they are looking for, and they are going to send something back, probably in XML, that you have to parse and deal with. Some gateways then have a 2nd round where you have to send something BACK to them, and they back to you, and you have to parse and deal with it. Coming up with a perfect PayPal integration with built-in testing account, took me a solid month.

    If you found the exchange between Lenny and me, that is all I had to go on too. It really is what you find in that post - post the data to the gateway, get the result and parse...

      Re: XML HELP Please!!!

      Have you selected a payment processor? If it is PayPal or, then, if you can get a copy of the AlphaSports ecommerce app, there are instructions in there for sending the credit card info. I've used that for a number of event registration sites.

      If it is someone else, like SafePay(Federated) or Pay Trace, then they have very complete API documentation you can use, and they'll be glad to help to get you for a customer. I also have customers using those.

      Hey, if I can do it, then I'm sure you can too.

      I use a dialog component for entering and sending the info. Much easier and much more control than a grid!

        Re: XML HELP Please!!!

        Thanks for the replies.

        I will be using BillingTree formally EPP. Yest they are very helpful...however the first step is getting the XML data extracted. I like the idea of using a dialog...I already have those setup to collect information....and write to the payment table....

        No its a matter of extracting Queried records into an XML file for batch processing.

        Am I approaching this the right way? and if so....What commands would I use to Query records from the Dialog and wrap into an xml file.

        Then there is a matter if

        Thanks again...for your replies.

        Steve I will look fir the post you referred to.

          PLease tell:

          How would do you do this:

          use a Dialog's aftervalidate event to send data from the same data-table that the grid is displaying on the screen.

            You can't use a dialog's event if you are using a grid. There are however new events in V10 that allow this, such as "AfterInsertRecord".

              Re: XML HELP Please!!!

              In Grids you can use the:

              CanInsertRecord event to fire something when a new record is added

              CanUpdateRecord event to fire something when an existing record is edited.

                Re: XML HELP Please!!!

                Scott - sorry you're getting tossed around a bit. The problem is that the solution depends on what your payment gateway wants, and what their process is. If the question is, 'how do I wrap my data in XML', please study this snippet from my payment process. All the fields with "t_" are variables defined earlier in the code. This is just one way to do this, and even though it looks complex, note that I am just creating a text file in a variable named req. Later I send this text to the payment gateway and get their response. This XML file is specific to the payment gateway and would not work with any other.

                '	req = "test"
                ''DEFINE XML TO SEND
                req = "<?xml version='1.0' encoding='utf-8' ?>" + crlf() + \

                  As always, your knowledge, and willingness to share information, is outstanding.

                  I will work on this and continue to post my status on this thread....for others with Web Services and XML troubles.

                  Thanks again Stave.
