php - Accessing session data outside Joomla -

-

I'm trying to run an application outside of Joomla (not in the form of a plugin) and I'm logged in user's Want to use information (user id) I'm thinking how should I go about doing this? Is there a file in which I can join? I tried to use $ _SESSION but it appears blank.

Is there a simple solution to my problem? Thanks for your time.

Actually it seems as easy as not. Joomla comes with its unique session-ID-generation and some encryption in place, using handheld sessions, so the only way to get Joomla session data is to use the appropriate Joomla functions (as suggested by other suggestions). To do. There was a recent project where we needed to move a Joomla certified user in a separate application. We did this by adding a Joomla adapter which provides the Joomla user class immediately, the user reads the data, puts everything in an encrypted cookie and redirects back to our application. There we read encrypted cookies, instantiate our own user objects and discard the cookie. Since this is not 100% secure, we are changing the system to write user data in a database table and read it from our application - we avoid insecure way through a cookie because this cookie is encrypted (and in this Sensitive user information that is sufficient to authenticate a user) it will be transferred to the wire and can smell. 

  Define ('_JEXEC', 1); Define ('JPATH_BASE', dirname (dirname (__ FILE__))); Define ('d', DIRECTORY_SEPARATOR); Need_once (JPATH_BASE DS 'contains' DS 'defines.php'); Need_once (JPATH_BASE.Ds 'contains' DS 'framework.php'); $ Mainframe = JFTC :: Mill Application ('Site');

The above basic script is required to access the Joomla resources.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
