php - Alternative to passing variable info through URLs -

-

I am writing a php / mysql app which uses a few different tables.

Table 1 stores user information (name email etc.), table 2 store, user widget, and table 3 store those different widgets configuration.

The way I am doing this now, the key to an automatic increase in Table 1 is that I use the specific user skills when they use Table 2, then it creates a line In which the table is the key ID, as well as the "UID", which is the key ID, from that specific user of Table 1. When the user wants to set the settings for their widgets, in Table 3, this is what I call "cxid", or config xid, which is unique widget id from Table 2.

This goal is to limit which users are visited, and clearly used for config configuration purposes.

The problem is, when a person passes the URL in the UID, when calling widgets. This is clearly a security problem because you can change it and see other people's widgets. But I do not want anyone to know how this is being done. Is there a way to pass the variables between the scripts that do not use the URL, but the form is not being used either?

You can use

Basically, you store all the necessary information about the user on $ _ session / <>, and retrieve it on every page load.

For example, on first page load: 

  session_start (); $ _SESSION ['UID'] = 123;

By default, the user will receive a cookie identifying the session, but there is no other information in it.

On the second page load, you can call: 

  session_start (); $ X = $ _SESSION ['UID']; // $ x Now 123 // Run a Query Here!

will read the user's cookie, search the session information (by default stored in a temporary file location) and fill the last time stored with the $ _ session Saw them

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...
