windows - Check status of one port on remote host -

-

I need a command line that can check the status of the port on the remote host. I tried ping xxx.xxx.xxx.xxx:161 but it does not recognize the "host" I thought it was a "good" answer until I got the same command against the host I used to know that the harbor is open. This is a batch file on Windows that will check the status of the remote port, then run the command that uses that remote port for information, then the remote port check command again, use that command for that information Ports on the next server, and so on. I have seen everywhere and thought that Ping can do this, but different versions of Ping should be, I think the server I am doing on this does not show that option.

Just for Chuskale, I tried a web based remote port checker from a website - and the results were correct for both "server" and server server, though, with 500+ server IPS in it Can not use it in a batch run

Is there something that is that simple? My Pearl skills are extremely raucous (use it or lose it), except batch, do not know any other windows based languages ​​Unix is ​​my skill, but these widows should be executed from server 2003.

You are looking for a port scanner such as, or both, which are used by Windows, Linux, and Mac Available for OS X

For example, check Telnet on a known IP: 

  For example, from 20 to 30 on host.example.com Find open ports:  
   
 Nc -z host.example.com 20-30

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...
