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.

    Re: Refresh Shadow automatically

    That's not the correct result.
    Maybe best to restart Alpha completely and try again (on the Master DB)
    I get this result:

    dim network_optimize as p

    ?a5_load_settings("NetworkOptimize",network_optimize)
    = check_portion = 1
    outofdate_flag = 1
    version_number = 109

      Thank you Jo, for trying to help, I still get the same
      dim network_optimize as p

        Jetson,

        Are you sure you have pressed ENTER after each line in the interactive window?
        I have tested this on Alpha version 10.5 on two versions, each on a different PC and get the required result.

          If the dim isn't executed you get this error..

            Re: Refresh Shadow automatically

            yap Jo, as you can see there is a space on my reply post#17, which I copied from the interactive window.Sometimes Jo, being a beginner in alpha five, if something goes wrong, what i thought for sure is I made the wrong code, which in desperation i searched for alpha wiki and samples on this forum, or immediately post the question,then if i found a code and tried to implement it in my own by copying and pasting which i don't get the desired result, With this situation, I am not encouraged to do things on my own because I will be doubting if I still can get the desired result (Sometimes not Always). The last statement is just a plain opinion, And it's good that we have this Forum, without it, I'm sure of myself that I can't use Alpha five as my development tool because unlike C# or VB .NET, codes are everywhere, Maybe someone will say, Why not go for c# or VB then? Well, Alpha five is much easier to learn but sometimes can get me stuck for days in some simple problems. back to reality, I just want the code above to check for version number before refreshing the shadow, other than that, i can refresh the shadow with Refresh_Shadow().

              Al, I'm pretty sure you are talking about executing the code in the Interactive window, I don't want the client to go to the interactive window to press enter, the code needs to run from a function called on a button. And I get that error when the function is executed. And for some reason, i'm not getting that error anymore, instead i get a result like this. "= <Has no sub-properties> "

                Jetson,

                I understand what you are going through, I took me quite some time and a lot of reading to come to this solution.
                The purpose of this function is to automatically refresh a Shadow DB once the version number is changed on the Master DB.
                As explained in the first post the function is called in the autoexec script, so the client (shadow) will detect a new version and the Refresh_Shadow is executed and the usual refresh window pops up, showing the progress. You as the developer take care of the Master DB and the settings for Network Optimization.
                I cannot remember if I may have overlooked something that might cause the error but one thing I recall is that I had an operational situation in which the Shadows were updated once the version number was increased in the Network Optimization settings on the Master.
                So my advice is to do the following as a matter of test:
                - Set the Network Optimization settings as shown in attached picture;
                - Create a Shadow;
                - Test if Shadow actually works fine;
                - Now increase the version number on the Master DB in the Network Optimization settings;
                - Restart the Shadow and see if the shadow refresh is triggered automatically.

                If all this works fine, that should be your basis to start again with the first post in this thread.

                Best of luck,

                  Re: Refresh Shadow automatically

                  Has anyone noticed that if you set your version number to reflect a date (YY.MMDD) you lose any trailing zeros? I tried this function today for version 12.0710 and it returns 12.071. I am also setting a character field with this value to display on a form, but using val(myvers_no) unfortunately does the same thing. I don't suppose there is a way around this since the app version number is a numeric field?

                    Robin,

                    There should be an easy way around that.
                    Why don't you consider the format YYYYMMDD and enter 20120710? I would guess that the way the number is stored isn't really important but you want it to be displayed correctly. For that purpose you could use a date formatting/conversion function.
                    Example:
                    dim version as n
                    version = 20120710
                    dim vrs as c
                    vrs = str(version,8,0)
                    ?stod(vrs)
                    = {10-07-2012}

                      Robin,

                      Yes, I can confirm the trailing zeros drop off. I currently do not use the same scheme as you do. I skip versions ending in 0 i.e. - 1.159, 1.161 (skipping 1.160)

                      I am sure there is probable a workaround.

                        Jo,

                        What am I missing here? How is what you are doing with your function significantly different or better than just using the option to Automatically update the Shadow Database when the version changes?

                          Raymond,

                          It's not that it is better. The Alpha option to Automatically update the Shadow Database is aimed at automatic detection of a new version.
                          The end user however needs to confirm whether or not the Shadow will actually be updated. I simply wanted to avoid end user intervention.
                          I use this function in combination with a version management tool as mentioned in post #3.
