Hi, can someone explain this. delphi code.. internet connection status -

-

Can anybody explain this to me like I'm two years, not that he did not understand a fetish, just I do not Which router is, number 3? 4 What does it do? 

  Uses WinInet; Cost modem = 1; LAN = 2; Proxy = 4; Bus = 8; Function GetConnectionKind (var strKind: string): Boolean; Var Flags: DWORD; Start strKind: = ''; Results: = InternetGetConnectedState (@flags, 0); If the result when it is triggered (flags and modem) = modem then strKind: = 'Modem'; If (flags and lanes) = LAN then strKind: = 'LAN'; If (flags and proxy) = proxy then strKind: = 'Proxy'; If (flags and busy) = just strKind: = 'Modem busy'; End; End; Process TForm1.Button1Click (Sender: Tubbed); Var strKind: string; If GetConnectionKind (strKind) then ShowMessage (strKind) will begin; End; [InternetGetConnectedState] (the Bitmask first parameter that looks like this:

/ P> 

  76543210 & lt; - bit number || |||| || || + + - INTERNET_CONNECTION_MODEM || || + - INTERNET_CONNECTION_LAN || | + --- INTERNET_CONNECTION_PROXY || + - --- INTERNET_CONNECTION_MODEM_BUSY (no longer used) | + ------ INTERNET_CONNECTION_OFFLINE + ------- INTERNET_CONNECTION_CONFIGURED

type if went given a bit, the connection is in. so if bit Norte is set to 2, you can connect to the proxy.

in addition, the function has a TR UE / FALSE gives value, indicating whether you are connected to the Internet or not.

In your code, you have values, 1, 2, 4, 8, that match the decimal value of those bits Counts from right to left.

Actually the code inspects each and every time, and sets the strKind variable for a text to indicate the nature of the connection.

Are you asking "whic h router? 3? ", And I believe that you mean" How do I know that my connection is through a router? " "I would think it would be like a LAN connection. Perhaps there is a bridge somewhere to use the LAN via Internet.

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...
