reg delete always bringing prompt in c#

I'm using a commandline execute to run a reg delete /f. Now when I do it via commandline it works as intended, but if I run it from C# I still get a prompt.
Now I'm wondering where the erorr lies....thus why do I still get a prompt when I call the command via C# despite the /f parameter being used.
Edit: A small info here: .NET Framework is 3.5
The code that is being used is as follows:
LaunchProcessAndWait(#"cmd",
#"/c reg delete " + "\""
+ #"HKLM\Software\Policies\Microsoft\Internet Explorer\Main"+ "\""
+ #" /v DisableFirstRunCustomize /f",
"");
public static string LaunchProcessAndWaitForOutput(string commandline, string args, bool returnError, bool returnOutput, string workingDir)
{
ProcessStartInfo info = new ProcessStartInfo(commandline, args);
if (workingDir != null)
{
info.WorkingDirectory = workingDir;
}
info.UseShellExecute = false;
info.RedirectStandardOutput = true;
info.RedirectStandardError = true;
info.CreateNoWindow = true;
Process p = Process.Start(info);
string outStr = "";
string errStr = "";
p.OutputDataReceived += new DataReceivedEventHandler((sender, e) =>
{
outStr += e.Data + "\r\n";
});
p.ErrorDataReceived += new DataReceivedEventHandler((sender, e) =>
{
errStr += e.Data + "\r\n";
});
p.BeginOutputReadLine();
p.BeginErrorReadLine();
p.WaitForExit();
p.Close();
return "" + (returnOutput ? outStr : "") + (returnError ? errStr : "");
}
}

Mplayer Dump Audio from video, working good only on non C hard drive

I'm using Mplayer to extrac audio from video via command line. This is the command i use:
mplayer -ao pcm:fast:file=aaa.wav aaa.avi
I copied Mplayer.exe and aaa.avi both on windows drive (C:) and on the root directory of an external hard drive (in my case X).
When i execute from C the dumping start at normal speed (i see the video on real time) and aaa.wav is not created by Mplayer.
When i execute form X the dumping start at fast speed (as requested by the -ao pcm:fast audio driver) and the aaa.wav is correctly created.
I have the same issue in my app, here the code i use to do it:
public static string DumpWav_ConsoleOutput = "";
public static int DumpWav_ProcessID = 0;
Process DumpWav_Process = null;
private void DumpWav(string SourceFileName, string DestinationFileName, bool NeedToCut, TimeSpan Start, TimeSpan End)
{
//cancelliamo le variabili
DumpWav_ConsoleOutput = "";
//Handle della finestra di Media Player
Variables.MediaPlayerHandle = 0;
Variables.MediaPlayerHandle = (int)MediaPlayer.Handle;
Thread thread = new Thread(() => _DumpWav(SourceFileName, DestinationFileName, NeedToCut,Start, End)); //il thread principale di Dump Wav
thread.Start();
while (thread.IsAlive) //aspettiamo il suo completamento
{
Application.DoEvents();
}
var myForm = new Output();
myForm.SetOutputText = Variables.ConsoleOutputMP;
myForm.Show();
Variables.MediaPlayerExit = true;
// ok il processo è terminato
}
private void _DumpWav(string SourceFileName, string DestinationFileName, bool NeedToCut, TimeSpan Start, TimeSpan End)
{
string Output;
Output = RunDumpWav((output) => { }, SourceFileName, DestinationFileName, NeedToCut, Start, End);
}
// Media Player avviato da questa funzione
public string RunDumpWav(Action<string> output, string SourceFileName, string DestinationFileName, bool NeedToCut, TimeSpan Start, TimeSpan End)
{
if (output == null)
throw new ArgumentNullException("output");
string args;
ProcessStartInfo ps = new ProcessStartInfo();
ps.FileName = FindMediaPlayerPath("mplayer.exe");
ps.UseShellExecute = false;
ps.RedirectStandardInput = true;
ps.RedirectStandardError = true;
ps.RedirectStandardOutput = true;
ps.CreateNoWindow = true;
ps.WorkingDirectory = #"x:\";
args = "-wid ";
args += Variables.MediaPlayerHandle;
args += " -ao pcm:fast:file=";
args += DestinationFileName;
if (NeedToCut == true)
{
args += " -ss " + Start + " -endpos " + End;
}
//args += " -vo null -vc null -quiet ";
//-wid will tell MPlayer to show output inisde our panel
args += " " + SourceFileName;
ps.Arguments = args;
using (DumpWav_Process = Process.Start(ps))
using (ManualResetEvent mreOut = new ManualResetEvent(false),
mreErr = new ManualResetEvent(false))
{
DumpWav_Process.OutputDataReceived += (o, e) => { if (e.Data == null) mreOut.Set(); else output(e.Data); };
DumpWav_Process.BeginOutputReadLine();
DumpWav_Process.ErrorDataReceived += (o, e) => { if (e.Data == null) mreErr.Set(); else output(e.Data); }; ;
DumpWav_Process.BeginErrorReadLine();
output = s => DumpWav_ElaborateOutput(s);
DumpWav_ProcessID = DumpWav_Process.Id;
//processMP.StandardInput.Close();
DumpWav_Process.WaitForExit();
mreOut.WaitOne();
mreErr.WaitOne();
//stringa di ritorno (tutto il contenuto della console)
return DumpWav_ConsoleOutput;
}
}
//controlliamo l'output della console
private void DumpWav_ElaborateOutput(string output)
{
Variables.ConsoleOutputMP = Variables.ConsoleOutputMP + output + Environment.NewLine;
if (output.IndexOf("A:") != -1)
{
//some check here
}
}
I recently added this:
ps.WorkingDirectory = #"x:\";
But the result not change, the video speed is not fast and the wav file is not created by Mplayer.
In my app, like the C test, i receive some errors:
[AO PCM] Failed to open aaa.wav for writing!
Failed to initialize audio driver 'pcm:fast:file=aaa.wav'
One more question, when i use mPlayer to encapsulate videos inside my app the process start about one minute after i launched it... maybe concatenate with dumping issue?
Please, any suggestion?
Edit:
I discovered just now: If i start the command prompt with admin rights then also in C Drive Mplayer do the job in the right way...
My app unfortunately don't. I edited the manifest to grant admin rights but it's the same. Somewhere here at stackoverflow i read something about to useshellexecute to true but unfortunately by this way (i need to test anyway) i lose the ability to redirect input/output/error.
I need to find a way to start the process (then the mplayer.exe) from within my app, with admin rights, without use shellexecute...
Edit 2°
I created a simple button with this code:
string args;
//Handle della finestra di Media Player
Variables.MediaPlayerHandle = 0;
Variables.MediaPlayerHandle = (int)MediaPlayer.Handle;
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = FindMediaPlayerPath("mplayer.exe");
//psi.FileName = #"x:\mplayer.exe";
psi.UseShellExecute = true;
psi.CreateNoWindow = true;
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.WorkingDirectory = Environment.CurrentDirectory; ;
psi.Verb = "runas";
args = "-wid ";
args += Variables.MediaPlayerHandle;
args += " -ao pcm:fast:file=";
args += #"x:\aaa.wav";
args += #" x:\aaa.avi";
psi.Arguments = args;
Process.Start(psi);
:-( same result, Mplayer is not able to open audio driver and to save file..
Fail, again.. 3° edit:
I tried using CMD:
private void button2_Click(object sender, EventArgs e)
{
ProcessStartInfo processInfo;
Process process;
Variables.MediaPlayerHandle = 0;
Variables.MediaPlayerHandle = (int)MediaPlayer.Handle;
string args = "";
args = #"x:\mplayer.exe -wid " + Variables.MediaPlayerHandle + #" -ao pcm:fast:file=x:\aaa.wav x:\aaa.avi";
MessageBox.Show(args);
processInfo = new ProcessStartInfo("cmd.exe", "/c " + args);
processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = true;
processInfo.Verb = "runas";
process = Process.Start(processInfo);
process.WaitForExit();
MessageBox.Show("terminato");
process.Close();
}
Now i see the first frame of the video and Mplayer freeze...
I'm losing my hope to use mplayer :-(

Finally i solved...
This is the code:
if (output == null)
throw new ArgumentNullException("output");
string args;
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = FindMediaPlayerPath("mplayer.exe");
//psi.FileName = #"x:\mplayer.exe";
psi.UseShellExecute = false;
psi.RedirectStandardInput = true;
psi.RedirectStandardError = true;
psi.RedirectStandardOutput = true;
psi.CreateNoWindow = true;
psi.WorkingDirectory = Path.GetDirectoryName(DestinationFileName);
psi.Verb = "runas";
args = "-wid ";
args += Variables.MediaPlayerHandle;
args += " -ao pcm:fast:file=";
args += Path.GetFileName(DestinationFileName);
if (NeedToCut == true)
{
args += " -ss " + Start + " -endpos " + End;
}
//args += " -vo null -vc null -quiet ";
//-wid will tell MPlayer to show output inisde our panel
args += " " + SourceFileName;
psi.Arguments = args;
As i understand i need to move the Process.WorkingDirectory to the same folder as the destination file (in my case the wav).
Now it rocks :-)
NO need for UAC
NO need for useshellexecute = true
Thanks stanley for your help!

How to read CGMiner output?

I am trying to read the CGMiner output in a C# program I am writing. I successfully read/write the standard thread input/output. But for some reason CGMiner does not write to the standard cmd window output, and I can't read it in C#. Any ideas?
This is my process start:
public void start() {
proc = new Process();
proc.StartInfo.FileName = "CMD.exe";
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.UseShellExecute = false;
proc.OutputDataReceived += (s, e) => updateConsoleOutput(e);
proc.Start();
proc.BeginOutputReadLine();
}
This is the function I use to write to the console:
public void RunCommand(string cmd = "") {
if (cmd.Length > 0) {
ConsoleInput = cmd;
}
StreamWriter myStreamWriter = proc.StandardInput;
myStreamWriter.WriteLine(ConsoleInput);
myStreamWriter.Flush();
ConsoleInput = String.Empty;
}
These are the functions I use to read from the console:
public delegate void consoleOutputCallback(string message);
private void updateConsoleOutput(DataReceivedEventArgs outLine) {
if (!String.IsNullOrEmpty(outLine.Data)) {
this.Dispatcher.Invoke(
new consoleOutputCallback(updateConsoleText),
new object[] { outLine.Data }
);
}
}
public void updateConsoleText(string message) {
this.OutputBlock.Text += message + "\n";
}
HINT: Don't know if it helps, but CGMiner will overwrite the entire console window, and cursor always stay at top left and does not move. All command before running CGMiner is overwritten.
Forgot to add, this is console command I use:
cd C:\cgminer\
del *.bin
cgminer.exe -o stratum+tcp://global.wemineltc.com:3335 -O yongke.1:x -g 2

You need to set the --per-device-stats flag in order for GPU stats to be written into stream
And don't forget to add this to the code in question
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.RedirectStandardError = true;
proc.ErrorDataReceived += (s, e) => updateConsoleOutput(e);
....
proc.Start();
proc.BeginErrorReadLine();
Most of miners use standart Error stream instead of standart Output stream (to write both output data and errors) for some reason..

the only thing that made it work for me was
-T
here is my working code
Task StartGPUMiner(object set)
{
MinerParams m = new MinerParams();
m = (MinerParams)set;
var tcs = new TaskCompletionSource<object>();
Process p = new Process();
ProcessStartInfo start = new System.Diagnostics.ProcessStartInfo();
start.FileName = m.ApplicationPath + "\\cgminer\\cgminer.exe";
start.Arguments = " -I " + m.GpuIntisity + " -T --scrypt -o " + m.sProtocol + m.ServerName + ":" + m.ServerPort + " -u " + m.UserName + "." + m.WorkerName + " -p " + m.ThePassword + " " + m.GpuParams;
start.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
start.RedirectStandardOutput = true;
start.UseShellExecute = false;
start.CreateNoWindow = true;
var proc = Process.Start(start);
proc.OutputDataReceived += (s, e) =>
{
try
{
this.Invoke((Action)delegate
{
txtLog.Text += (e.Data + Environment.NewLine);
});
}
catch { }
};
try
{
proc.Exited += (s, e) => tcs.SetResult(null);
proc.EnableRaisingEvents = true;
proc.BeginOutputReadLine();
}
catch { }
return tcs.Task;
}

How to compile Java from C#?

I'm trying to use the following C# code to compile Java using javac:
Process p = new Process();
p.StartInfo.FileName = "javac";
Directory.CreateDirectory(Application.StartupPath + #"/TempJava");
p.StartInfo.Arguments = "-d "Application.StartupPath + #"/TempJava" + files;
p.Start();
"files" represents a string variable containing the name(s) of the *.java files.
All in all, I want to create a new folder, and then take the Java files (from where ever they may be located) and compile it into a class file(s) in TempJava.
For some reason, the code doesn't work, no errors, no warnings, but when I run it and check TempJava, there's no files in it.

Just because your child process ends with a possible error, it doesn't mean your parent process must be aware of it.
Inspect the process' exit code and standard output stream, and especially the standard error stream. Your answer lies in there...

here i have 2 buttons run and compile here is some code to help.
private void comp_Click(object sender, EventArgs e)
{
string text = "javac " + label1.Text + file + "#pause" + "#stop";
text = text.Replace("#", System.Environment.NewLine);
File.WriteAllText(label1.Text + "Compile.bat", text);
Process proc = null;
try
{
proc = new Process();
proc.StartInfo.FileName = label1.Text + "Compile.bat";
proc.StartInfo.CreateNoWindow = false;
proc.Start();
proc.WaitForExit();
}
catch
{
}
}
private void runp_Click(object sender, EventArgs e)
{
string news = file.Remove(file.Length - 5);
string text = "java " + news + "#pause";
text = text.Replace("#", System.Environment.NewLine);
File.WriteAllText(label1.Text + "Run.bat", text);
Process proc = null;
try
{
proc = new Process();
proc.StartInfo.FileName = label1.Text + "Run.bat";
proc.StartInfo.WorkingDirectory = label1.Text.Remove(label1.Text.Length - 1);
proc.StartInfo.CreateNoWindow = true;
proc.Start();
proc.WaitForExit();
}
catch
{
}
}
all i really do is create a batch and run it using c#.

Passing values for method

I beginner for programming. So can you please show me how to pass values for your compile() method.
class CL
{
private const string clexe = #"cl.exe";
private const string exe = "Test.exe", file = "test.cpp";
private string args;
public CL(String[] args)
{
this.args = String.Join(" ", args);
this.args += (args.Length > 0 ? " " : "") + "/Fe" + exe + " " + file;
}
public Boolean Compile(String content, ref string errors)
{
//remove any old copies
if (File.Exists(exe))
File.Delete(exe);
if (File.Exists(file))
File.Delete(file);
File.WriteAllText(file, content);
Process proc = new Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.FileName = clexe;
proc.StartInfo.Arguments = this.args;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
//errors += proc.StandardError.ReadToEnd();
errors += proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
bool success = File.Exists(exe);
return success;
}
}

public Boolean Compile(String content, ref string errors)
Do you want to know how to call this? Try . . .
string content = "#include <stdio.h>\nmain(){\nprintf(\"Hello world\");\n}\n";
string errors = "";
CL k = new CL(new string[2] {"/Od", "/C"});
if(k.Compile(content, ref errors))
Console.WriteLine("Success!");
else
Console.WriteLine("Failure: {0}", errors);
Hope this helps

Create a form using the designer, add a text box name it txtCplusplus and a button. Add a click event for the button.
Paste your CL class into the same file as event handler (form.cs or whatever you call it), NOT inside a method or property.
In the buttons click event handler put this code:
CL cmp = New CL();
string errs;
if (cmp.Compile(txtCplusplus.Text, ref errs) {
MessageBox.Show("Success");
} else {
MessageBox.Show(errs);
}
