How to run 2 files c# without opening window

I got 1 mapper (.exe) and 1 driver (.sys) and i want to do so that when i execute them i want to run mapper as admin with the driver and not create a window (keep it hidden). can anyone help. I have the following code down but nor does it run the mapper as admin with the spoof and it still also creates a window! help!
string map = "C:\\SCSpoofer\\mapper.exe";
Process myProcess = new Process();
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.CreateNoWindow = true;
myProcess.StartInfo.Verb = "runas";
myProcess = Process.Start(map, sys);
System.Threading.Thread.Sleep(150);
myProcess.Kill();```

// Create a Process to launch a command window (hidden) to create the item templates
Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.WorkingDirectory = Project.ServicesFolder;
startInfo.Arguments = "/C " + CreateServices;
process.StartInfo = startInfo;
process.Start();

Opening a certain page on a PDF file in WPF

I Need to open a specific page of a pdf file.
I tried:
private void Button_Click_20(object sender, RoutedEventArgs e)
{
Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
process.StartInfo = startInfo;
startInfo.Arguments = "/A \"page=5\"";
startInfo.FileName = #"J:temp.pdf";
process.Start();
}
but it still opens the first page. Still unsolved.
if i Change to this
private void Button_Click_20(object sender, RoutedEventArgs e)
{
{
Process process = new Process();
process.StartInfo.Arguments = #"/A \"page=5\" \"J:\\temp.pdf"";
process.StartInfo.FileName = #"J:\temp.pdf";
process.Start();
}
}
i get seven Errors (Semicolon, page no context...)

It's unclear on how the arguments need to look like. Assuming it's J:\temp.pdf /A page=5
this should work:
Process process = new Process();
process.StartInfo.Arguments = #"/A page=5";
process.StartInfo.FileName = #"J:\temp.pdf";
process.Start();
However I'm not sure if you can pass arguments to a file name like this, I'd assume you need to call your PDF viewer's executable and pass both the file name and the page argument like in the question already linked in the comments:
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = #"C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe";
startInfo.Arguments = "/A \"page=5\" \"E:\\Users\\You\\temp.pdf\"";
Process.Start(startInfo);
This works on my machine (replace paths as needed of course).

"StandardOut has not been redirected or the process hasn't started yet" when reading console command output in C#

Thanks to #user2526830 for the code. Based on that code I added few lines to my program since I want to read the output of the SSH command. Below is my code which gives an error at line while
StandardOut has not been redirected or the process hasn't started yet.
What I want to achieve is that I want to read the output of ls into a string.
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = #"f:\plink.exe";
startinfo.Arguments = "-ssh abc#x.x.x.x -pw abc123";
Process process = new Process();
process.StartInfo = startinfo;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.Start();
process.StandardInput.WriteLine("ls -ltr /opt/*.tmp");
process.StandardInput.WriteLine("exit");
process.StartInfo.RedirectStandardOutput = true;
while (!process.StandardOutput.EndOfStream)
{
string line = process.StandardOutput.ReadLine();
}
process.WaitForExit();
Console.ReadKey();

Try setting standard output redirection before starting the process.
process.StartInfo.RedirectStandardOutput = true;
process.Start();

It might be that the process already terminated when you try to read the output (dues to your "exit" command). Try the below slightly modified version where I moved your while loop after the "ls" command but before the "exit" command.
It should read the output of your "ls" command fine, but unfortunately will most probably hang at some point as you will never get EndOfStream on the StandardOutput. When there is nothing more to read, ReadLine will block until it can get read another line.
So unless you know how to detect the last line of the output generated by your command and break out of the loop after you read it, you may need to use a separate thread either for reading or for writing.
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = #"f:\plink.exe";
startinfo.Arguments = "-ssh abc#x.x.x.x -pw abc123";
Process process = new Process();
process.StartInfo = startinfo;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardOutput = true;
process.Start();
process.StandardInput.WriteLine("ls -ltr /opt/*.tmp");
while (!process.StandardOutput.EndOfStream)
{
string line = process.StandardOutput.ReadLine();
}
process.StandardInput.WriteLine("exit");
process.WaitForExit();
Console.ReadKey();

Run CMD command without displaying it?

I have created a Process to run command in CMD.
var process = Process.Start("CMD.exe", "/c apktool d app.apk");
process.WaitForExit();
How can I run this command without displaying actual CMD window?

You can use the WindowsStyle-Property to indicate whether the process is started in a window that is maximized, minimized, normal (neither maximized nor minimized), or not visible
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
Source:
Property:MSDN
Enumartion: MSDN
And change your code to this, becaeuse you started the process when initializing the object, so the properties (who got set after starting the process) won't be recognized.
Process proc = new Process();
proc.StartInfo.FileName = "CMD.exe";
proc.StartInfo.Arguments = "/c apktool d app.apk";
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit();

There are several issues with your program, as pointed out in the various comments and answers. I tried to address all of them here.
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "apktool";
//join the arguments with a space, this allows you to set "app.apk" to a variable
psi.Arguments = String.Join(" ", "d", "app.apk");
//leave it to the application, not the OS to launch the file
psi.UseShellExecute = false;
//choose to not create a window
psi.CreateNoWindow = true;
//set the window's style to 'hidden'
psi.WindowStyle = ProcessWindowStyle.Hidden;
var proc = new Process();
proc.StartInfo = psi;
proc.Start();
proc.WaitForExit();
The main issues:
using cmd /c when not necessary
starting the app without setting the properties for hiding it

Try this :
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.WaitForExit();

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.FileName = "dcm2jpg.exe";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

How to print a PDF to something other than the default printer

I used this code to print a pdf file from acrobat reader.
private void SendToPrinter()
{
ProcessStartInfo info = new ProcessStartInfo();
info.Verb = "print";
info.FileName = #"c:\output.pdf";
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process p = new Process();
p.StartInfo = info;
p.Start();
p.WaitForInputIdle();
System.Threading.Thread.Sleep(3000);
if (false == p.CloseMainWindow())
p.Kill();
}
However, it prints through default printer.
How can I select the printer to send it to? default.
I have tried with a property for ex: info.Arguments, but that doesn't work.

Use the /t command line argument to force adobe to use a specific printer:
AcroRd32.exe /t path "printername" "drivername" "portname"
See the PDF developer FAQ for more info:

How about using the "printto" verb? pasing "\\\server\printer" for info.Arguments
