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.

  • Saving User Login Name To Local Storage

    I want to save the last user login name on my login UX to local storage so the next time the user logs in they dont have to type in the username again. I assume I would have to have a variable that would be assigned the string that is inputted into the username textbox. How would exactly how I go about doing something like this?

      Re: Saving User Login Name To Local Storage

      I looked at Persistent Logins video and tried to get that to work but couldnt. I simply want to store the username now and have the username textbox filled with the last username inputted. I couldnt tell by the video how to do it. I assume I would code it something like this:

      dim username as c

      username = e.datasubmitted.username

      BUT do I put this code in after Validate Client Side Event? How do I save that to local storage and set the username textbox to the variable username?

        Re: Saving User Login Name To Local Storage

        Would it be something like this in the after Validate Client Side Event?

        var userObject = {e.datasubmitted.username);
        localStorage.setObject('username', userObject);
        userObject = localStorage.getObject('username');
        username = userObject

          Re: Saving User Login Name To Local Storage

          Pretty much... but you need to check for localStorage... and you don't need to use the event you mention.

          In your Javascript functions put this...

          Code:
          function supports_html5_storage() {
            try {
              return 'localStorage' in window && window['localStorage'] !== null;
            } catch (e) {
              return false;
            }
          }
          In the UX afterLogin event... add this in front of whatever other code you have in there...

          Code:
          var ls = supports_html5_storage();
          if (ls){
          	var lsUserId = {dialog.Object}.getValue('Userid');
          	localStorage.setItem("ls_UserId",lsUserId);
          } else {
          	alert("Local Storage not available");
          }
          You don't really need the alert. If localStorage is there... great... if not... then no persistent UserId... up to you what you want.

          Finally, in the UX onRenderComplete event...

          Code:
          var lsUserId = localStorage.getItem("ls_UserId");
          if (lsUserId){
          	{dialog.Object}.setValue('Userid',lsUserId)
          }

            Re: Saving User Login Name To Local Storage

            In my login UX component I have a textbox called UserName that is where I want the username stored after the user logins

            This is what I have in Javascript Function of that Login UX Component:

            var ls = supports_html5_storage();
            if (ls){
            var lsUserId = {dialog.Object}.getValue('UserName');
            localStorage.setItem("ls_UserId",lsUserId);
            } else {

            }

            This is what I have in afterLogin Event:

            var ls = supports_html5_storage();
            if (ls){
            var lsUserId = {dialog.Object}.getValue('UserName');
            localStorage.setItem("ls_UserId",lsUserId);
            } else {

            }

            {dialog.object}.runAction('Call Main Panel');


            This is what I have in onRenderComplete event:

            var lsUserId = localStorage.getItem("ls_UserId");
            if (lsUserId){
            {dialog.Object}.setValue('UserName',lsUserId)
            }


            HOWEVER, the UserName textbox is not being populate with the last Login Name after logging in

              Do I have to rebuild it in Phonegap first?

                Re: Saving User Login Name To Local Storage

                Take a look at your Javascript function. If that's code you have... then it's the same as in the afterLogin event... so that's wrong. Check my post again and correct the Javascript function.

                    I don't know how your PhoneGap Build app is set up. I didn't know, until this post, that you were working with a PhoneGap Build app.

                    The code works in a web app and a PhoneGap Build test app I created.

                    When you debug your PhoneGap Build app, are you seeing any console errors?

                      It works. I just had to submit it to Phonegap to rebuild the app. Thanks for your help!
