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.

Getting US Standard date value?

  • Getting US Standard date value?

    I am looking for an xbasic way to get the "real" current date value. That is to say, NOT THE SYSTEM DATE but the real date.

    I am trying to negate the possibility of the user changing the system date with the intent of back dating to negate an expiration date.

    Every command I have seen is influenced by the system settings. Anyone know of a date function that is not influenced by the system date settings?

    Thanks,

    Gene

    Re: Getting US Standard date value?

    I am trying to negate the possibility of the user changing the system date with the intent of back dating to negate an expiration date.
    i am not an expert in these, but here is some food for thought.
    1) when the system is installed you could create a start_table with the installation date and total valid days. installation date will be obvious and total number of days is an integer number of days from the installation date.
    then create a script that calculates the expiration date like
    expiration_date = jtodate(jdate(installation_date) + total_valid_days)
    if expiration_date <> date() then
    msgbox("ALERT", "System date is wrong, software is deactivated, call me right away!")
    deactivate
    end if.
    2) this will require internet connection.
    create a simple a5w page in your computer or a licensing computer and the page only contains this code
    <%a5
    ?date()
    %>
    call it a5_date.a5w publish it to be available from outside and you can host it in your computer
    and then in the customer computer create a call to this page like
    dim cP as p
    cP = http_get(your_computer:port/directory/a5_date.a5w")
    dim current_date as d
    current_date = cP.body.
    that will give you the current date.
    then you can do action for licensing.

    these seems so convoluted way, as far as i know there is no way to beat the system clock. even going back to epoch depends on the system clock as far as i can tell.

    edit: on second thought, the first method also is dependent on system clock and not desirable for the question on hand.
    there was an article in learn alpha.com about licensing method by someone other than peter. if i find the link i will post it here later. may be that will help.

      Thanks for trying Gandhi but as you noted, still relying on the system clock. There is a national time standard available but I do not know how to get that information into Alpha using xbasic. That's the challenge I am putting out there in "creative land"....

        you could use my second suggestion, if you like.
        just like calling any service, but your own service.

          The attachment resets the system date/time via internet server. You might be able to modify it to just get the internet data/time.

          reset system time.txt
          There can be only one.

            I also replied Gene, but my entry seems to have been deleted.
            The essence of the comment was that I would not worry too much, as changing the system date causes a whole lot of other issues with virus checkers, SSL's and reporting.
            Like Govindan, I sort of suggested a table to count the number of start up's of the application. You could also set a free monthly update procedure so each month a new licence key would be sent. Then you could see who wasn't renewing.
            As Stan pointed out ( at least I think he did ) be wary of changing system dates on someone else's machine. Capture the date only if possible.

              INET::TimeCheck::NTPTime will give you the current date and time based on pool.ntp.org. There is also INET::TimeCheck::NISTTime which does the same thing using NIST servers, but their service is much less reliable so it sometimes errors out.

                For the :: challenged, would you expand on how to implement INET::TimeCheck::NTPTime on the desktop?

                  Thanks for that Stan. I am one of the "challenged".
                  I must presume that anyone changing the system date will also figure out that an I/net connection will probably need to be disabled, and if they did that, the application could be prevented from launching?

                    From the Interactive Window:

                    Code:
                    ?INET::TimeCheck::NTPTime
                    = 04/11/2017 12:37:50 84 pm
                    But I just noticed this question is in the V11 area, and this is Alpha Anywhere functionality. I'm sorry for the confusion.

                          I am using Alpha Anywhere V3.11 and I get "ERROR: Property not found" So it was added sometime after that.

                              Lenny, This is a really nice feature! Thanks.

                              Is this an undocumented feature that will not be removed anytime soon? I cannot find it in the online help documentation.

                              Thanks again,
