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.

    UX Loads too slowly

    My UX's load too slow ...far too slow (They load via a tree control in a tabbed ui if that makes a difference). I don't have all sorts of custom code in any of these either. I just use the controls/tools that Alpha provides. The server that they are hosted on isn't the problem.

    I'm looking for suggestions on how I can go about troubleshooting this phenomenon. Build 4237.

    Thanks in advance.

    Re: UX Loads too slowly

    There's a video about splitting your UX's if they are complex to improve loading speed but I cannot find it right now, maybe someone else ?

          Re: UX Loads too slowly

          Unfortunately this video doesn't apply to me. I haven't deployed a mobile app nor do I use panel cards.

          The UX's I've made imitate medical forms and as such have many many fields on them. I use the absolute container with a pic of the form as a background and then just place the UX controls appropriately.

          One UX has around 100 controls in it and takes a full 16 seconds to load. That just isn't going to fly with my users but I don't know what else to do about it.

            Re: UX Loads too slowly

            What back-end database are you using?

            I presume you have your UX bound to the table with the correct primary key in which case it's already indexed. If not, index whatever key you're finding with.

            Internet or Intranet?

            What happens if you make a copy of the UX, chop half the controls out and load it? Does that cut the time in about half?

            Calculated fields/controls? Lots of code in the OnExecute event?

              This is for a web app (internet) with a SQL backend. The UX is bound to a single table and works great once it loads. No calculated fields. No code anywhere other than to get the primary key and save data.

              I haven't setup an index...would I need to with only a 100 fields? ...I haven't tried cutting the UX in half. Even if that sped up the UX that wouldn't help me. It's a medical form that needs to be up on the screen in it's entirety.

                How fast/slow does the form load if you take out the background pic?

                  I'm not suggesting you deliver it that way. But it may be helpful in understanding what's going on. You may find it still takes 16 seconds, in which case the control count is not the issue. I also like Rich's question about the background graphic.

                    I see now ... I'll try both of these things in a couple hours and report back my findings here. Thanks!

                      Do you have conditional formatting on the client-side that might be slowing things down? I think firefox/firebug, IE and Chrome all have tools to help analyze where the javascript is spending its time.

                        Yup. Use Firebug, check the Net tab and you can often learn a lot.

                            No...no conditional formatting. The the absolute container, background image, and ~100 controls, and a few buttons that save, delete, new record...

                              On the UX properties page there is the "compute data binding code at design time". How much of a difference in load time if you turn that on?

                              And, also turn on "compute panel layout HTML at desgin time". Not sure if it would make any difference in your case, though.
