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.

  • Dynamic Images

    So, I've come across a requirement recently that calls for employee photos to be displayed on RFID scan inside of a UX component..
    I have the RFID already set up to pull employee data from MSSQL and it works flawlessly... Currently, I am pulling employee id and badge number(from RFID tag). I also have a folder filled with photos that are all named according to employee id number.

    Now, I know that in general, saving photos inside of the database itself is bad news.. so I was curious as to whether alpha is able to pull photos straight from the project folder.. I have looked into both the image control and data bound image control in UX but haven't found any built-in function that allows me to accomplish this.. Then again, I may have missed it completely.

    Has anyone ever done this sort of thing before and if so, what was your method for doing so?

    Any help is greatly appreciated.

    Regards,

    One way is to set up an unbound Image control (from Other Controls) and, when you've got an Id, set the ".src" of this control to your Id.

    Let's say your Images are in a folder on your server, under A5Webroot, called Images... and they are jpgs.

    After you've scanned your RFID and have your Employee Id, use something like this code to get the value of your Employee Id... and then get a pointer to your Image control... and set the Image src.

    Code:
    var imgId = {dialog.Object}.getValue('EmpId');
    if(imgId){
    	var iObj = {dialog.Object}.getPointer('IMAGE_1');
    	iObj.src = 'Images/' + imgLoc + '.jpg';
    }

        A good discussion on images and SQL can be found here. For security reasons I keep them under 256k and in the Database in a separate table.
