Get Current User in XBasic

[psamuels56]

Hi-

I thought this would be easy, but I haven't had any success getting this to work, so I can use some guidance.

I want the current user's Login ID (e.g. [email protected]) to use in an XBasic Ajax Callback I'm running. I've tried several different ways of doing it without success. In one of my UX components (in the same application), I've successfully captured the Login ID by putting "=session.currUserID" in the "Initial Value" of a hidden field... and it works perfectly.

But, now, I'm working with a Grid, so I can't easily set the initial value of a field, so I'm looking for a better way to do it.

Here's what I tried. In the Server Side "OnGridIntitialize", here's what I added:

CurrentUser1.jpg

Then, I put this in my XBasic and got the error shown.

CurrentUser2.jpg

Actually, I thought that would work, but it obviously did not.

If you have any suggestions about how I could capture the user's login ID for my XBasic, I'd appreciate it.

Thanks,
Phil

Try this

a5ws_logged_in_user_values(pUser,request,session)

args.Set("whatUserId",pUser.userid)

Hi Mike-

THANK YOU so much for responding so quickly...AND for such a brilliantly concise answer!

I added the code you suggested and still got an error, BUT that's because I didn't "dim" the pUser veriable ("Dim pUser as p"). Once I did that, it worked PERFECTLY... and is doing exactly what I hoped for.

It is so kind of you (and other Alpha users) to offer your time and expertise to other users. I hope you know how much it's appreciated.

Thanks again,
Phil

Re: Get Current User in XBasic

I would use the Context Object methods now.

Web applications that were built before the Context object was available or using now deprecated functions or objects should be updated to use the Context object so that the web application will transition to running under IIS or any other web server technology available in the future.

This will work

Context.Security.CurrentUser

Hi Stephen-

Thanks for writing. I have 2 questions:

1. Is there a reason why this is better than Mike's suggestion (or is it just another way of doing it?)? Mike's suggestion is working for me.
2. Where would I put that line? I'm trying to use the User ID in an XBasic command. Do I "dim" a variable "as c = Context.Security.CurrentUser" (e.g. Dim CurUser as c (or p?) = Context.Security.CurrentUser")?

Re: Get Current User in XBasic

You can use Stephen's suggestions like this...

dim userName as C = Context.Security.CurrentUser

From Alpha: Using the Context object is the preferred way to get information about a request, response, or other context of the server since other objects have been deprecated since version 11. Many of the deprecated objects will not work under IIS.

This "Context" object is new to me...didn't even know it existed until today. If a5ws_logged_in_user_values() has (or is being) been depreciated then I would use the Context method.

Mike and Stephen-

That makes sense... Thanks for all the help and the explanation... I'll give it a try.

Phil,

1. Its not better than what Mike has suggested, just saying that Alpha is recommending it going forward so that we don't run into problems down the road.
2. As Mike responded, you can dim the result into a variable if that's what you want but you don't necessarily have to. For instance you could have a textbox on a control and simply set it's default value to:

= Context.Security.CurrentUser

That will return the logged in user name to the control.
However, you can use it in an xbasic function, which is what I think you were looking to do. I have an xbasic function where I'm returning the result to a control called RESULT. So, the function contains

e.control.Result = Context.Security.CurrentUser

This particular object doesn't require an argument, or even parentheses for that matter.

Hope this helps,
Stephen
