Hy,
I need to launch a vnc viewer in a winform (ultravnc in my case) and I need to send two parameters to see the remote desktop and after several issues, I can't find any solutions.
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents = false;
proc.StartInfo.FileName = "C:/Program Files/uvnc bvba/ultravnc/vncviewer.exe";
proc.StartInfo.Arguments = host;
proc.Start();
the first argument "host" is the ip of the pc and that just work.
After that, ultravnc ask me the password for the remote desktop connection.
And this is where I can't find any solutions :
1)I try to add a second arguments :
proc.StartInfo.Arguments = mdpVNC;
But VNC take this as a replacement of the "host" variable.
2)I try to use the SendKeys class but it doesn't work
3)I try the property "PasswordInClearText" but that doesn't work either.
I try several things and I don't want to use an external package (like vncSharp or other, because these solutions don't suit me)
I need help plz.
Thanks in advance.
StartInfo.Arguments is a string, and you put in there the arguments. Make the string that has the arguments as you would write them in the command line. For example:
startInfo.Arguments = "host -dsmplugin msrc4plugin.dsm";
That is for the first example in UltraVNC Viewer Commandline Parameters
.
Or whatever you need.

I'm trying to make an app, which could open a pdf file in a browser (Chrome) and search for a certain word automatically. However, I can't find anything about passing commands to Google from C# whatsoever.
Process process = new Process();
process.StartInfo.UseShellExecute = true;
process.StartInfo.FileName = "chrome";
process.StartInfo.Arguments = "console.log(\"TEST1\")";
process.Start();
I've tried running Chrome with StartInfo.FileName = "chrome", which went well. After that I thought I could add some Arguments: StartInfo.Arguments = "something" and that's where I ran into two problems:
The browser takes the Arguments as a URL and tries to open it as a web page (which of course fails)
I couldn't find the console command to run the search function in Chrome
Is there maybe some google API capable of this thing? Also please note that I'm not trying to use "search". I need the browser to literally focus on the word it found
If anyone here knows how to solve even one of these problems, I would be really grateful. Also this is my first question on StackOverflow (and I might have forgotten something) - I can give some additional info, if you ask
I searched on internet and found many possible ways of running chkdsk utility in c# using cmd.exe as file name and passing command as /c chkdsk drive_letter:/f /x
But I want to run chkdsk utility on drive ,without involvement of cmd.exe i.e; Purely using internal features of c#.
Your suggestions are greatly appreciated.
Chkdsk is a console application. So how do you wanna start a console application without the console? The only thing you can do is hiding the window from the user.
As you for sure already noticed: MSDN - Chkdsk
According the console-window:
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;
This together should bring you to your goal.
So I am having issues with the "net use" command in C#. Basically, I am using the code written here. The code works great, however I have multiple ids that need to be used sequentially. Unfortunately, when trying to connect to another ID, the connection remains in "net use " in Windows, so this exception is thrown:
Win32Exception: Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed.
Now to me, the obvious thing would be to execute the command prompt programmatically to delete the connection when I am done using it. Here is the code that I am running to delete the connection:
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/K net use delete \\IPAddrofserver";
process.StartInfo = startInfo;
process.Start();
I only use /k so I can see if the command works. After this code executes, it says "The network connection cannot be found." However, if I manually open the start menu, and type net use, I can see and delete the connection. I think this may be related to the fact that when running the command prompt programmatically, I notice its being given administrative privilege as opposed to running it under my user token, but I cannot be sure. Any help regarding this would be greatly appreciated.
EDIT: Adding in the command prompt deletion code during the WnetCancelConnection2 actually operates correctly, and deletes the connection from net use. However, checking net use manually outside of the program reveals that the history of the connection still exists and is open. Whoami command reveals the same user. Any reason why there is a discrepancy between what happens programmatically and what happens when I check manually?
You probably need to start your process with elevated privileges. See the accepted answer here for how to do this. You could also choose to call the relevant Windows API directly, to avoid spawning other processes and dealing with those complications.
I am trying to use Plink to access information on a machine. I followed this tutorial:
http://www.mindfiresolutions.com/Creating-a-SSH-connection-using-plink-PuTTY-via-C-application-1760.ph
So far I am only using my program to just open up Plink, and I will be adding in the login information and such once I can at least get Plink to be openable in my program. I have this based on the tutorial:
ProcessStartInfo psi = new ProcessStartInfo(#"C:\Windows\System32\cmd");
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
psi.UseShellExecute = false;
psi.CreateNoWindow = false;
Process process = Process.Start(psi);
Thread.Sleep(3000);
string cmdForTunnel = "plink";
process.StandardInput.WriteLine(cmdForTunnel);
process.WaitForExit();
Thread.Sleep(10000);
//DoBusinessLogic();
process.StandardInput.WriteLine("logout");
Thread.Sleep(10000);
if (process.HasExited)
{
process.Close();
process.Dispose();
}
But nothing is displayed, which bothers me. The command plink is supposed to display the help information on how to use the program (I will be replacing the command with something more useful later), but the command prompt remains empty. I also experimented by replacing plink with ipconfig, which also displayed nothing.
I know how to open up cmd myself and type in plink to access it. I want to replicate this action in my program.
You have many faults in your code:
You are redirecting an output, and you are not reading/processing/printing it (that's why "nothing is displayed")
Running plink by "typing" plink to cmd.exe is insane. You can run plink directly, avoiding cmd.exe completely (and even if you needed to use the cmd.exe, you should pass plink.exe to it on a command-line: /c path\plink.exe). And no, running it directly would not cause Plink to close instantly.
Calling WaitForExit() without reading the redirected output will deadlock your code once an output buffer fills. See Remarks section for ProcessStartInfo.RedirectStandardOutput. Alternatively, use process.StandardOutput.ReadToEnd() (it's like WaitForExit, but also reads the output). It's actually what the MSDN recommends in the previous link.
If you are going to execute one command only, using Plink, it's also better to pass the command on Plink command-line, rather than "typing" it to its (redirected) input:
plink.exe -ssh user#host command

In my local network ,I have more than 10 pc.I need to take care all of the pc.I want to know all pc’s hardware informations.I also want to control those pc,Suppose ,at this moment I want to restart one of my client pc.Is it possible in C#.if have any question plz ask.Thanks in advance
I use bellow syntax to execute command.
try
{
// create the ProcessStartInfo using "cmd" as the program to be run,
// and "/c " as the parameters.
// Incidentally, /c tells cmd that we want it to execute the command that follows,
// and then exit.
System.Diagnostics.ProcessStartInfo procStartInfo =
new System.Diagnostics.ProcessStartInfo("cmd", "/c " + "shutdown /r /m \\172.16.1.3 /t 1 /");
// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
// Get the output into a string
string result = proc.StandardOutput.ReadToEnd();
// Display the command output.
Console.WriteLine(result);
}
catch (Exception objException)
{
// Log the exception
}
Using the above code I get the message "The network path was not found."

If you want to make a program which u can able to get the remote system information. You have to use Microsoft's Remoting.Here we can able to create an object in the remote system and we can able to control it.
It is possible to get System's information by executing the System.Diagnostics.ProcessStartInfo.
It is possible to get system information using "systeminfo" .It is possible to take the output using C#
Pls chk the this.
I hope this will be useful for you.
I don't think this is a C# question, cause this can be done much more elegant with things like Group Policy Editor, System Management Server, System Center Operations Manager, etc.
To do some simple tasks on a remote machine you can take a look into the PsTools.
With those requirements my first stop would be WMI. There's for example the Win32_OperatingSystem class with its Reboot and Shutdown methods and the Win32_Processor with all kinds of information about the CPU.
This MSDN section shows you how to use it from .Net: Getting Started Accessing WMI Data
This MSDN section has quite a lot of short VBScript samples for doing various things using WMI, and even if the code is different, at least you can see which WMI classes/methods/properties you should be looking at: WMI Tasks for Scripts and Applications
Please note RB's comment though, you'll need to have the correct permissions for it to work.
Edit: Forgot that since you'll want to connect to other computers, this sample will be useful: How To: Connect to a Remote Computer
