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.

    Mobile Device - Keep browser active when switching to another app

    A "little" thing I can't figure out:

    With a mobile application (web app, not PhoneGap), if the user navigates away from the browser for any reason, then returns to the browser, the browser automatically reloads the page. The result is a potential loss of work, having to log in again, etc.

    Is there a way to retain the browser and page so that when the user comes back to it, they just pick up where they left off?

    Re: Mobile Device - Keep browser active when switching to another app

    I think we need to start distinguishing a mobile app from a web app running on a mobile device. You're running a web app... not a mobile app.

    Mobile applications are either fully or partially native device applications and can therefore take advantage of a webview and plugins designed to help navigation and other specific needs. Although it's still run in a webview it can, and does, talk to the device.

    Web applications are exactly the same applications you run on your desktop browser... except they're run in a mobile device browser and are subject to the same external influences any other browser page is subject to.

    What you're asking is somewhat dependent upon how you navigate away from your application and how much work you want to do in order keep it's state.

    PhoneGap Build has an InAppBrowser plugin that allows you to come and go from a mobile app without destroying the app's state.

    Web apps can attain certain aspects of this but you have to build it in. Do a web search on maintaining a web page state and you'll find a lot of information... and that's the problem... there are a bunch of ways to sort of do it.

    You specifically mention login which means you're not saving login data and are at the mercy of session vars and session timeouts. You can use local storage to maintain login information. List data can also be stored locally. Actually, anything can be stored and retrieved locally so maybe using local storage would be a good solution. When the page loads, check local storage and if you've saved anything, restore it.

      Well kind of true, but you can do some things. Watch this quick Video Play Video
