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.

http_get_page2 - cache?

  • http_get_page2 - cache?

    So I have a desktop app that sends out patient appointment reminder texts. I'm finding that http_get_page2 and/or alpha is caching the message results and messing up my appointment updates.

    The code will loop through an sql query to send the appointments and inserts the sms particulars into a sql database. I then loop through those records to check for text results from the patient and updates the appointment calendar in another database. The code works but it seems I'm dealing with a cache issue and I can't seem to find how to turn it off or clear it before it checks for results.

    I can unload a5 and re-load the app and it updates the records accordingly. Any insight is greatly appreciated.

    Code:
    recinfo = foo.value
     v_messageid = word(recinfo,1,"|")
       v_visitid = word(recinfo,2,"|")
     v_patientid = word(recinfo,3,"|")
     pDlg1.Set_Bottom_Message(convert_type(i,"c")+" skipped "+convert_type(x,"c"))
     chkmsg = http_get_page2("[URL]https://sms2.cdyne.com/sms.svc/GetMessageStatus?MessageID="+v_messageid[/URL])
        *property_from_xml(chkmsg,chkmsgresult)
        dom=*XML_Document(chkmsg)
        chkme = dom.Output("*tag")
     noresponse = *any(chkme,"SMSIncomingMessageFromPhoneNumber")
                mr = occurs("SMSIncomingMessageFromPhoneNumber",chkme)
    If noresponse = .f.
     x=x+1
     goto nextrecord
    end if

    For the unenlightened, what does

    messing up my appointment updates
    mean to you.
    There can be only one.

      My poor choice of words: I meant to say the updates don't occur and messes up the goal of the application.

      The function fails to retrieve updated data from the url upon a subsequent call of the script (every 15 minutes). So the program sends the text message and then checks for replies every 15 minutes. If a reply is received within the first 15 minutes, the function works. The next time the script is called and someone else replies it fails and I have to unload and re-load to get it to work.

        Re: http_get_page2 - cache?

        http_get_page2() using a Microsoft ActiveX control that automatically caches quite aggressively. There are 2 approaches to address this:
        1. Make sure the URL for each request is unique. This can be done by appending an otherwise meaningless query string to the URL.
        2. Use a different HTTP function, such as http_get(), to send your requests.

          Thanks Lenny! I'll check the http_get() function.
