How to detect the user loged

Hi all

I have a scenario like this,

I have a global report in which some one-stop codes are available.
Once the user is logged into the system, I want to limit the report details according to its code window.

ex: report of the details (name, age, address, salary, branch)

one login user-> branch code is (COL)

do not be able to view the report details that are related to other sectors.

is it possible to do using Apex...? or I have to manage this through the query...?

If I need to manage it from a query, then I must detect the session of connection clearly as the user login name.
Then I can use the name and the code of the branch of the connection table and proceed to the request... I guess im correct ;)

is it possible to detect the login name of the user and get him to a sql query?

ex: say MAX direction COL login name of the

Select * from TABLE_SAMPLE where branch_code = (select branch_code from USERS where uname = 'MAX' ;);

-----------------------------------------------------------------------------------------------------

can someone give me a hand on this regard.plss... ???

Thank you
Max

This is known as Fine grain Access Control (FGAC).

Both. The best approach is to use the private virtual database (DPV), using integrated Security VPD attribute Apex to put in context.

VPD requires a database Enterprise Edition. A similar approach can be developed using the parameterized views, new setting the context through the security of APEX VPD attribute in other editions.

Use the substitution string integrated APP_USER to get the ID of the authenticated user:

select * from TABLE_SAMPLE where branch_code=(select branch_code from USER where uname= :app_user);

  • How to detect the user touch and hold the screen for touch screen devices?

    Hello

    I want my code to do the following:

    when user touch and hold on the screen{
        myThread.start();
    }
    
    when user release the finger on the screen{
        myThread.done();  //a method to stop the thread
    }
    

    Any ideas? Thank you very much

    Never to change never return super.touchEvent (...) to return true (well, you can do it for complete events such as MOVE or GESTURE. SWIPE_...) -you will disrupt the event processing complex (just about everything, but downwards and upwards).

    The code works for me (I do something else, with more visual impact, so I know for sure that it does). One thing, try - check the status of your Thread (isAlive()) before you start, as DOWN seems to be generated twice.

    If you could be more specific with what "won't work" is, I would be able to help more.

    looking forward to responses CIHI to you guys.

    Thank you

    I thought you wanted to know if the user is on a call.  The code I gave you the will and sets the appropriate Boolean value.  Where and how you use it is up to you isn't it?

    I would have thought that the logic in your code to push would be simply

    If (! onCall) {}

    Somehow, I blocked my user account (login) and I tried to help but can't find any info. How to UNLOCK the user account. Thank you

    Hello

    Click the account icon that was locked and enter the password IF you know and otherwise:

    Try Safe Mode - several times, press F8 that you start. The Admin account there is no default password
    so unless someone has changed, you should have access there. Then Control Panel - accounts - users
    Manage another account - use this down your user account (to the lowest level) APPLY/OK
    then go back and reset it to the Admin APPLY/OK - this clearly allows corruption. Do this several times.
    Then fix the password in your usual account. Do not forget to leave your account administrator if you
    wish.

    If no joy Mode without failure:

    Try this - use the hidden administrator account to lower your user account (to the lowest level) APPLY/OK
    then go back and reset it to the Admin APPLY/OK - this clearly allows corruption. Do this several times.
    Then fix the password in your usual account. Do not forget to leave your account administrator if you
    wish.

    Make another Admin account with your password and use it to fix the others if necessary. (just for
    repair, don't use regular account, not a safety valve) always keep a spare ADMIN account.

    DO NOT LEAVE THE ENABLED LSA OR USE DAILY. If it corrupts you are toast!

  • How to detect the color pages in a PDF file?

    I use a plug-in of Acrobat C++ read/modify a PDF file.

    I need to get the total number of pages in the PDF file and the page numbers of the pages in color.

    So far, I was able to get the total number of pages using PDDocGetNumPages() with no problems.

    However, I can't find an API that lets me know if a particular page is color or not. Is there a way to do this?

    Thanks in advance!

    But what happens if there are RGB data which means black or grey (R == G == B), that means black or RGB?

    There is a code sample in the SDK to browse content in the PDF file, and then you can get the color space and color of each object.

    But you really need to do background research on the colors & spaces to achieve this properly.
