I am totally new to using C# for networking purposes, can anyone show me in an easy way how to create in a few lines a console application that reads the IP information (Packets)..."Sniffer", i dont need a class or anything.. just in the main program 2 or three lines that would give me this information.
Thank you guys
This is not possible to do in a two or three line C# program. You need to replace the winsock driver in the operating system itself so that the operating system will show you packets intended for others, and you can't put managed code into the kernel like that. This is why software like Wireshark usually also requires you to install WinPcap. That said, after winpcap is installed on a system C# can control it and use it to capture packets.

I cannot find any definitive information anywhere but the System.Windows.Forms.SendKeys class appears to have been blocked / disabled / depreciated in Windows 10.
I wrote a demo program that monitors the users keystrokes and if a user enters a known code it will pop up a form and then go off to a document database and return various strings (company names / addresses / contact lists etc) and replace the typed code with the retrieved string. SendWait is used to send the retrieved strings to whatever program typed the code.
I built the program on the companies Windows 7 desktops but when I ran it on my personal Windows 10 system it didn't work. A lot of reading later and I feel like a complete idiot but I cant let them take this project any further knowing that they wont be on Win7 forever.
So my question is has this sort of functionality definitely been disabled in Windows 10 or is there another way or method I would be able to use to achieve this behavior of inserting text into running programs.
Any help appreciated.
I found this Forum-Thread:
https://www.tenforums.com/software-apps/49635-sendkeys-not-working-windows-10-a.html
SendKeys is Blocked in W10. In W8.1 it still works.
There are other anoying things, like not allowing App to Read or Wright to Drive C. The "file" is there but W10 "hides" it or simply not allowing to access it.
There are Netwok problems also, not allowing App to work on LAN environement.
Well, my opinion is that W10 behaves like Malware to user PC. Useless.
They had no solution.
It looks as if Sendkeys works with some apps and not others. I can automate an older app by sending it keystrokes but newer apps like Chrome don't respond. The inconsistent behavior has seriously messed up scripts that worked fine under Win 7.
I have not found any official documentation that says that Sendkeys has been deprecated so the inconsistency looks to be a Windows 10 bug.
I am working on using a Raspberry Pi in an embedded project that will utilize wifi to communicate with external devices. The device should be able to act either as a standalone wifi hotspot that devices can connect to or in the case of the presence of an existing wifi network it should connect to that network so that the user does not have to give up his internet connection in order to connect to the device. I plan on making the device start up in hotspot mode, the user can then use the web interface to enter the details of a network that he wants the device to connect to, whenever the specified parameters fails to establish a connection then it defaults back to hotspot mode.
Now the technical stuff I am struggling with is that I want to implement the control software in C# running with Mono on Arch Linux on the Rapsberry Pi. I am struggling the find the Apis or libraries needed to manage the Linux wifi connection. On Windows it seems as if managedwifi.codeplex.com can be used but it does not seem to be compatible with Linux.
My last resort would obviously be to execute shell commands and then parse their outputs, but considering how crude and possibly unreliable that would be this is obviously my last resort.
Any ideas regarding what I should do?
PS. Another thing I might consider before using shell scripts, if it makes a difference is to use Raspbian or some other distro instead.
Actually calling shell commands from a managed code is not a very bad idea. They are reliable, very well tested and mostly lightweight and sometimes just a wrapper around kernel or other modules function. This is also seems to be the same method Node.js modules use when they want to access something lowlevel or related to networking. For example see this source code: node-wireless/node_modules/wireless/index.js
If you don't like it this way there is always "Interop". The same way that you can DllImport() libraries in Windows, you can do in Linux. See here: http://www.mono-project.com/Interop_with_Native_Libraries
IMHO the second solution doesn't worth the effort. Calling shell commands is elegant and neat enough.
my pi is starting into wlan0 as AP with hostapd, when a AP also a lighttpd is starting and give a web interface do change the settings. the web interface verify and write the input in a sqlite3. a second script is doing the canges according to my changes. (like add, edit or remove wifis in wpa_supplicant, reset wlan0 to be a part of an existing wlan like set to dhcp, tell wpa_supplicants...)
except the lighttpd and sqlite3 all components are already on the Raspery. you dont need any mono or c-libraries
for writing the scripts i use python but also perl is working (even php for the frontend)
I happen to have an old RFID reader from Touchatag. It's pretty old already but it seems to work fine. Unfortunately, Touchatag has stopped their support for this device and besides, it required an internet connection which doesn't make it a very practical solution...
What I would like to do is to use this device without the need for an internet connection and inside an application that's written in C#. Don't know what this app is going to do, but right now I'm investigating all the options that are available for this device. So, does anyone know a good C# library and other sources that allow me to use this device?
(Btw, this is purely experimental.)
I don't know of any C# libraries of hand, but you can check out either:
IOTOPE
Java project that includes a low level library and a more high-level interface to the reader. You can probably adapt it to provide an interface to your C# application.
See http://blog.iotope.com/node/quick-starter/
libnfc
Low level NFC library. Mostly targeted for unix like systems, but could be put to work on windows as well.
See https://code.google.com/p/libnfc/
If you're experimenting with RFID, rather than works the bugs out of interfacing with a custom reader, you can buy a cheap USB RFID reader for around 10 £/$/€
A lot of them simply act like a keyboard and 'type' characters into your application (some even add a carriage return which is handy)
I am making windows 8 , c#/xaml app. Is it possible to compile and run a java console program like " hello world"?
Since winRt apps cannot use System.Diagnostics.Process then it cannot figure how to compile and run it. Or if compile is not possible, just being able to run a .class file is fine.
I have tried useing System.Diagnostics.Process to open cmd to compile but that class isn't supported.
Thanks for any advice.
There's certainly not an elegant or intended (& documented) way to launch a process like you describe from a Windows Store application (it's intentionally locked down and there is no "command prompt for the new Windows store UI apps). There are some that suggest that there may be a way via CoCreateInstanceFromApp, but the documentation now reads as if that API only works for a limited number of Microsoft built COM objects.
While you can launch other installed Windows Store applications, the Java compiler will definitely not be one of those without a significant and unusual repackaging by Oracle (or some third party). While it's possible that someone is working on that, it would seem unlikely (given the limited need for such functionality).
Depending on the nature of the Java code, you may want to look for a Java interpreters that could be embedded within your application, and call it directly, especially if the Java code is trivial.
Your application requirements would suggest that a traditional Windows desktop application would be a better fit.
I'm thinking of writing an app to selectively transfer photos/music to and from my iPhone, mostly for fun and personal convenience. However, I'm stuck at the very beginning -- where do I look to find information on how to do this?
Pretty much every link I see talks about developing applications that run on the iPhone, but nothing about desktop app for interfacing with an iPhone.
I'm on Windows (no access to a Mac, but I'll take suggestions for that for when I eventually acquire one), and I'm most familiar with C#, but other languages are definitely an option.
Can anybody offer me a few pointers on getting started? Thanks.
Edit: to clarify further, I don't need information on how to write applications that run ON the iphone. There are plenty of resources out for that. :) What I'm looking for it some pointers on how to "talk" to an iPhone or an iPod through the USB cord, if that's even possible.
Edit #2: I found libmobiledevice library that effectively does what I'm talking about on Linux. I don't think I'm too keen on attempting to port it over to Windows, though. :)
I found what I was looking for: SharePodLib. Thanks, everyone.
I recommend and have used the following options:
Option 1:
Run a small and light webserver in the iPhone and of course, use HTTP to transfer. I recommend mongoose websever, i've tried it with very simple and very heavy load. Also here, you can find an actual drag and drop project to deploy this webserver in the iPhone.
Option 2:
Use something like Bonjour, this is something very useful if you want the "smart" discovery of your device in the network, maybe for opportunistic peer discovery. You can check here and here, to understand how to get bonjour to run in the iPhone and use it to exploit discovery and sharing.
Hope it helps!!
Unfortunately, there's no no way to sync an iPhone app with a Mac app over USB, at least in the current SDK. As already stated, you'll have to either sync over HTTP or use the local network. You might want to check out ZSync, a Cocoa library for bonjour syncing (I haven't used it, and it's in early development stages, but it looks interesting).
Unfortunately there is no officially sanctioned method to do what you describe. In Apple's view the only application that should have visibility of that information is iTunes. There are applications out there that appear to be able to do this, but I suspect they have reverse engineered the USB protocol and are thus open to being locked out if the protocol changes.
