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.

  • SMS Messaging

    I am doing SMS messaging in one of my apps, using the method of sending an email to all participants with their phone number and text message carrier address.

    The problem is that this seems to work intermittently. Sometimes I will send a message and everyone will get it, sometimes only half of the folks will get it.

    There doesn't seem to be a rhyme or reason.

    This is a tour company. The text messages are going to people during their trip, providing up to the minute instructions and information. (Such as please meet back at the bus in the north parking lot at 10pm.)

    These people will often only be going on 1 trip, so we don't want to require everyone to download an app - because they won't do it. However, we collect everyone's cell phone carrier and phone number prior to the trip, so I have all that info.

    Currently, I am sending the message in batches of 80 or less, with all of the messages being blind copied. It may be that some servers are rejecting the mass text - but like I said, it works to everyone sometimes and not others - so I don't know what is going wrong.

    Does anyone have a working SMS app that I can adapt to use with my system.

    Willing to pay for the help.

    We would be sending from to 20 to 500 text messages at a time, multiple times per day. Different numbers each time.

    Any suggestions appreciated.

    If you have an app that might work for me, respond here or by private message, please.

      Re: SMS Messaging

      Larry,
      my esperience, sending using phone number & the phone company extension
      is never reliable ... We had a carrier who for some reason hold back the message for few days.

      plus it is a histle to ask tourist for their carrier company name.

      there are several good discussion on this topics ..
      please search ..

            Larry,

            I just implemented Twilio too. I agree - works great!

            One question though: Have you found a way to use this to send a text message to say, 10 phone numbers at once?

              Re: SMS Messaging

              I have a function called Send TW. It takes a contact_id, which is the table for an email or text message.

              I got this function from Alpha Help, I think, and modified it from there.

              FUNCTION SendTw AS C (vContact_ID AS C )

              'debug(1)
              '==CONNECTION AND VARS

              dim cf_1 as extension::CurlFile
              dim flag_1 as l
              dim ce as extension::Curl

              vHasError = "N"

              cn.open("::name::conn")

              vselect = "select sid, token, messagefromid, apiurl from twillio"
              cn.execute(vSelect)
              vTwilioURLPre= cn.resultset.data("apiurl")
              vSID = cn.resultset.data("sid")
              vTwilioURL=vTwilioURLPre+vSID+"/Messages"
              vToken = cn.resultset.data("token")
              vPassword=vSID+":"+vToken

              vMessage = cn.resultset.data("Message")

                if the vSid, token you say above are true sid and token., please remove that. twilio charges by usage. your sid and token can be harvested here and used elsewhere.

                      Thanks for posting this Larry. I was hoping for a built in way to use action scripting, but if this is what is needed to send SMS to multiple people, I will give it a try.

                        Ok, I am taking a stab at this myself tonight and I have an xbasic error I cannot figure out.

                        Code:

                        END FUNCTION

                        The error is "bad expression character" at the while statement with "while" being the cuplrit. Any ideas? Also when I commented it out I of course did get a phone number back but only one row, also I did NOT get a text from twilio. My account is working fine if I just use the action button for a twilio message but I want to send out the message to multiple numbers not just one.

                            that looks the same, no?
                            This is a screenshot showing the error @ the "while"
                            while error.JPG

                            Changing it to
                            while eval_valid(cn.resultset.data("phone"))
                            does get rid of the error though...

                              so I got around the error, however, I am not receiving an SMS and not sure how to debug. The debugger shows a phone number in the Phone variable and all of the other info such as SID and Token are good so not sure how to get this working...
