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.

    Image Capture for List Detail View - Change upload folder programatically in javascript.

    I have a need to store image files captured by a mobile app in a sub folder from the main root images folder.
    Example: c:\images\12345 where 12345 is a specific job number. The job number is variable and known at the time of the image capture.
    I noticed that Alpha exposes the upload folder property. I found it in the Xbasic view of the UX, not the Javascript Global Declarations section of the image capture method.
    I have tried to reference the uploadfolder property which is part of the image control file path field, with no success.
    It would be nice to use a client side event to change the upload folder at the time of the capture. See screen shot. There are two events: BeforeImageCapture and OnImageCapture.
    Has anyone figured this out or advise if this is possible? Thanks in advance.

    You can use a session variable for the Upload folder... e.g. session.imagepath.

    Your supposed to be able to use an Alias as well... but the inline doc for this seems to be wrong... and it doesn't seem to work anyway.

    The trick is setting the session variable when you need it. At what point do you have the specific job number?

    You'd need to make an Ajax Callback to set that session variable at some point before the image upload action starts.

      1. I changed the upload folder to session.uploadfolder.
      2. Initialize the session.uploadfolder variable in the server side onDialogInitialize
      3. Write XBasic function - xbSetUploadFolder
      function xbSetUploadFolder as c (e as p)
      session.uploadfolder = "C:\images\"+ convert_type(e.DataSubmitted.EmployeeID,"c")
      end function
      4. Modify Synchronize List button to make callback to xbSetUploadFolder
      5. Execute the javascript {dialog.object}.saveListEdits('LIST1',{rows: 'current'}); in the AJAX "After callback complete Javascript"

      This works perfectly. It creates folder automatically too. Thank you.

      Last question: I wrote this app before the persistent login UX component was available so my app has no session variables so users are not timed out in the mobile app. They can stay logged in indefinitely just refreshing their data.
      Can I eliminate the session variable or prevent my app from timing out?
