Dynamic Images

[txsiccness]

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,

Re: Dynamic Images

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.

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.
