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.

Synchronization Errors

  • Synchronization Errors

    I have a relatively straightforward offline application. Sporadically, when the synchronization event is fired - {dialog.object}.saveListEdits('AllImportantList',{rows: 'allRows'}) - via an onclick event on a button, the synchronization process will fail at some point. I knew this because I would receive a "You have unsynchronized edit" message when trying to do a call back to refresh the list a subsequent time.

    To gain further insight on what was happening, I used the getAllErrors(); method to bring back the error message. Unfortunately, I'm more confused than ever because I have absolutely no idea what this error means:

    database could not find
    the data you requested"},
    database could not find
    the data you requested"}]

    Any insight would be greatly appreciated!

    I previously read in this forum that un-checking the "Check for write conflicts" option on your list would help with the error “The database could not find the data you requested”. Maybe worth giving it a try.

      Thanks Rusty. I saw that thread as well. I'm going to give that a try.

        Re: Synchronization Errors

        I've seen that error, and others. I don't have my LIST working 100% of the time, but it has gotten better with the following changes:
        1. Removed DateTime field from the field mapping that tracked when a record was last updated. I think there were data formatting/conversion issues with that field that made the system think it had been changed by someone else when it was actually due to loss of precision or something.

        2. Turned on "Detail View / Other Properties / "Use server-side synchronization log table" in the LIST builder. For me that made synchronization less flakey. (I also have "Clear syn log table after successful sync" turned on.)

        3. In the Web Project Properties, set a Connection String and Table Name under "Offline Data Synchronization Log Table Settings". I created a separate DB for the log tabl

        I fire a sync every time the users moves to a new row in the list and when a certain amount of time has passed since the last sync. I have code that prevents firing a sync if one is already in-progress and when the LIST is not dirty. I do expect my users to be online all the time.
