I realize that in Windows 7, it is not possible to save different credentials for the same host, but I need some workaround.
Can I provide the username and password manually in the code? Store them in a temp .rdp file?
Process rdcProcess = new Process();
rdcProcess.StartInfo.FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\cmdkey.exe");
rdcProcess.StartInfo.Arguments = "/generic:TERMSRV/192.168.0.217 /user:" + "username" + " /pass:" + "password";
rdcProcess.Start();
rdcProcess.StartInfo.FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\mstsc.exe");
rdcProcess.StartInfo.Arguments = "/v " + "192.168.0.217"; // ip or name of computer to connect
rdcProcess.Start();
The above code initiates a connection with .217 and I am not being prompted to provide a password.
Thanks for help.
If you want to use powershell you could add the credentials using
cmdkey /generic:DOMAIN/"computername or IP" /user:"username" /pass:"password"
Then call RDP connection using
Start-Process -FilePath "$env:windir\system32\mstsc.exe" -ArgumentList "/v:computer name/IP" -Wait
If you want to delete the credentials run
cmdkey /delete:DOMAIN/"Computer name or IP"
Remember to remove ""
This is an updated version from Krzysiek's post.
var rdcProcess = new Process
{
StartInfo =
{
FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\cmdkey.exe"),
Arguments = String.Format(#"/generic:TERMSRV/{0} /user:{1} /pass:{2}",
fp.ipAddress,
(String.IsNullOrEmpty(fp.accountDomain)) ? fp.accountUserName : fp.accountDomain + "\\" + fp.accountUserName,
fp.accountPassword),
WindowStyle = ProcessWindowStyle.Hidden
}
};
rdcProcess.Start();
rdcProcess.StartInfo.FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\mstsc.exe");
rdcProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
rdcProcess.StartInfo.Arguments = String.Format("/f /v {0}", fp.ipAddress); // ip or name of computer to connect
rdcProcess.Start();
While trying to figure out how to allow users into our network, without giving them the keys to the castle, I enabled Remote Desktop Access for a few members of my team. Thinking more about this, I quickly remembered a project several years ago while working for the Department of Defense. That project required us to "lock down" access to only necessary personnel and limited access to the programs on the servers. After spending some time on Microsoft's KnowledgeBase, we realized that we could create desktop "shortcuts" for those employees that made the RDP connection, logged them in and limited their access to one specific application on that server.
#echo off
cmdkey /generic:TERMSRV/"*IP or Server Name*" /user:%username%
start mstsc /v:*IP or Server Name*
cmdkey /delete:TERMSRV/"*IP or Server Name*"
quit
The accepted answer solves the problem, but has the side effect of leaving the credentials in the users credential store. I wound up creating an IDisposable so I can use the credentials in a using statement.
using (new RDPCredentials(Host, UserPrincipalName, Password))
{
/*Do the RDP work here*/
}
internal class RDPCredentials : IDisposable
{
private string Host { get; }
public RDPCredentials(string Host, string UserName, string Password)
{
var cmdkey = new Process
{
StartInfo =
{
FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\cmdkey.exe"),
Arguments = $#"/list",
WindowStyle = ProcessWindowStyle.Hidden,
UseShellExecute = false,
RedirectStandardOutput = true
}
};
cmdkey.Start();
cmdkey.WaitForExit();
if (!cmdkey.StandardOutput.ReadToEnd().Contains($#"TERMSRV/{Host}"))
{
this.Host = Host;
cmdkey = new Process
{
StartInfo =
{
FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\cmdkey.exe"),
Arguments = $#"/generic:TERMSRV/{Host} /user:{UserName} /pass:{Password}",
WindowStyle = ProcessWindowStyle.Hidden
}
};
cmdkey.Start();
}
}
public void Dispose()
{
if (Host != null)
{
var cmdkey = new Process
{
StartInfo =
{
FileName = Environment.ExpandEnvironmentVariables(#"%SystemRoot%\system32\cmdkey.exe"),
Arguments = $#"/delete:TERMSRV/{Host}",
WindowStyle = ProcessWindowStyle.Hidden
}
};
cmdkey.Start();
}
}
}
most of the answers are incorrect, it still request password and this because execute different processes on the same process instance.
using command line works perfectly:
string command = "/c cmdkey.exe /generic:" + ip
+ " /user:" + user + " /pass:" + password + " & mstsc.exe /v " + ip;
ProcessStartInfo info = new ProcessStartInfo("cmd.exe", command);
info.WindowStyle = ProcessWindowStyle.Hidden;
info.CreateNoWindow = true;
Process proc = new Process();
proc.StartInfo = info;
proc.Start();

I'm using Process to execute a batch file which will generate certificate file.
The code works great when I execute other file (which contains openssl command). But when I execute a file which contains keytool command, it executed, but no file was generated.
I've:
Set UseShellExecute true.
Set WaitForExit(-1) and find the return was true, so it did executed.
I clicked that batch file manually, and the file generates right away, so the command was fine :(
BTW I'm using .Net Core MVC.
I can't find any error code anywhere, so I'm at my wits' end now.
Does anyone has a clue? Any help would be very appriciated!
success code(openssl):
I generate a p12 file (a certificate format) in that folder first, and it works fine.
private string Gen_P12(string domain, string pwd)
{
//generate folder
string folder = #"D:\Temp\";
if (!Directory.Exists(folder))
Directory.CreateDirectory(folder);
//generate bat(p12)
string bat = "openssl.exe pkcs12 -export -inkey " + domain + ".key -in " + domain + ".cer -out " + domain + ".p12 -password pass:" + pwd +"\r\n";
//download in folder
var path = Path.Combine(folder, domain + "_P12.bat");
using (FileStream fs = System.IO.File.Create(path))
{
byte[] content = new UTF8Encoding(true).GetBytes(bat);
fs.Write(content, 0, content.Length);
}
Thread.Sleep(500);
//execute
ProcessStartInfo myBat = new ProcessStartInfo();
string name = domain + "_P12.bat";
myBat.FileName = name;
myBat.WorkingDirectory = folder;
myBat.UseShellExecute = true;
//Process.Start(myBat);
Process p = Process.Start(myBat);
p.WaitForExit(-1);
return folder;
}
fail code(keytool):
Trying to use that P12 file and keytool command to generate a keystore (also a certificate format) but fail.
private string Gen_KS(string domain, string folder, string CA_domain, byte[] cer, string pwd)
{
//generate bat
string bat = "keytool -importkeystore -srckeystore " + domain + ".p12 -srcstoretype PKCS12 -srcstorepass " + pwd + " -destkeystore " + domain + ".keystore -storepass " + pwd + "\r\n";
var path = Path.Combine(folder, domain + "_KS.bat");
using (FileStream fs = System.IO.File.Create(path))
{
byte[] content = new UTF8Encoding(true).GetBytes(bat);
fs.Write(content, 0, content.Length);
}
Thread.Sleep(700);
//execute
ProcessStartInfo myBat = new ProcessStartInfo();
myBat.WorkingDirectory = folder;
string name = domain + "_KS.bat";
myBat.FileName = name;
myBat.UseShellExecute = true;
Process p = Process.Start(myBat);
var a = p.WaitForExit(-1);
string route = folder + domain + ".keystore";
return route;
}
Thanks!
Thanks to #user9938, I solved the problem!
1. Brief conclusion:
I need to process the bat as administrator.
(And I still don't get why only do the keytool command needs administrator rights)
2. Find the errors: (How to apply StanderError when UseShellExecute=true)
In fact we don't have to set it true to execute commands.
Try this (replace execute section):
Process process = new Process();
try
{
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.FileName = "cmd.exe";
process.Start();
process.StandardInput.WriteLine(bat); //command string, not the bat file
process.StandardInput.AutoFlush = true;
process.StandardInput.WriteLine("exit");
StreamReader reader = process.StandardError;
string curLine = reader.ReadLine();
reader.Close();
process.WaitForExit();
process.Close();
}catch (Exception e){}
Check the value of curLine through Breakpoints, the error message was: "'keytool' is not recognized as an internal or external command, operable program or batch file".
3. How to solve it:
Just set the Verb attribute as "runas".
//execute
ProcessStartInfo myBat = new ProcessStartInfo();
myBat.WorkingDirectory = folder;
string name = domain + "_KS.bat";
myBat.Verb = "runas";
myBat.FileName = name;
myBat.UseShellExecute = true;
Process p = Process.Start(myBat);
var a = p.WaitForExit(-1);
Done! Thank you user9938<3
I execute net user command from C# and map the network to the local computer.
Below is my code:
string netUse = #"net";
string DomainUser = "Domain\User";
string parameters = "use \"" + ServerLocation + "\" " + server.Password +
#" /USER:" + DomainUser + #" /PERSISTENT:NO";
ProcessStartInfo psi = new ProcessStartInfo(netUse, parameters);
psi.CreateNoWindow = true;
psi.UseShellExecute = false;
Process p = Process.Start(psi);
I found that security sensor (Falcon) detected access with a plain password:
net.exe
ComandLine: "net" use "\ServerLocation\d$" Password /USER:
User /Persistent:NO
My question is:
Is it possible to hide password?
Is there a way to display the windows popup msg by using C#?
I mean by using the windows msg.exe program that can be used in cmd, for example:" msg * Hello "
PD: I know that i can use MessageBox.Show() instead. But i want to know if this is possible :(
I wrote 2 ways to do it but none worked:
Process.Start("cmd.exe","/C msg * Hello");
and...
Process cmd = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
Arguments = "/C msg * Hello",
UseShellExecute = false,
RedirectStandardInput = true,
RedirectStandardOutput = true,
RedirectStandardError = true,
CreateNoWindow = true,
WindowStyle = ProcessWindowStyle.Hidden
}
};
cmd.Start();
Did you try adding msg.exe directly?
Process cmd = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = #"msg.exe",
Arguments = #"* /v Hello",
WorkingDirectory = Environment.SystemDirectory;
WindowStyle = ProcessWindowStyle.Normal
}
};
cmd.Start();
I encountered the same problem.
This was because the project was configured as "AnyCPU" but the "Prefer 32-bit" option was checked in the "Build" tab of the project configuration. Uncheck that option and the problem will disappear.
Edit: personnaly, I use the following function to locate the binary according to the executable and OS platform (32/64 bits):
public static bool LocateMsgExe(out string returnedMsgPath)
{
returnedMsgPath = null;
string[] msgPaths = new string[] { Environment.ExpandEnvironmentVariables(#"%windir%\system32\msg.exe"),
Environment.ExpandEnvironmentVariables(#"%windir%\sysnative\msg.exe") };
foreach (string msgPath in msgPaths)
{
if (File.Exists(msgPath))
{
returnedMsgPath = msgPath;
return true;
}
}
return false;
}
And for invoking it :
if (LocateMsgExe(out string strMsgPath))
{
Process.Start(strMsgPath, "* \"Hello world!\"");
}

This is my solution. It consists of a webpage (.aspx) with a listbox (lstComputers), a textbox (txtMessageToSend), a dropdownlist to select the OU that contains the computers that will receive the message and a button (btnSendMessage).
This is the code for btnSendMessage on the aspx.cs
protected void btnSendMessage_Click(object sender, EventArgs e)
{
string searchbase = ddlZaal.SelectedItem.Text; //This is a dropdownlist to select an OU
DirectoryEntry entry = new DirectoryEntry("LDAP://OU=" + searchbase + ",OU=YourOU,OU=YourSubOU," + Variables.Domain + ""); //Variables.Domain is specified in the Web.config
DirectorySearcher mySearcher = new DirectorySearcher(entry);
mySearcher.Filter = ("(objectClass=computer)");
foreach (SearchResult result in mySearcher.FindAll())
{
DirectoryEntry directoryObject = result.GetDirectoryEntry();
string computernaam = directoryObject.Properties["Name"].Value.ToString();
lstComputers.Items.Add(computernaam); //This is a listbox that shows the computernames. To each computer a message is sent.
string pingnaam = computernaam + "dns.suffix"; //Might be necessary for connecting to the computes in the domain
string MessageToSend = txtMessageToSend.Text; //The text in this textbox will be the messagetext
Process process = new Process();
ProcessStartInfo psi = new ProcessStartInfo(#"C:\inetpub\wwwroot\PsExec.exe"); //Location of PsExec.exe on the webserver that hosts the web-application.
psi.UseShellExecute = false;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.RedirectStandardInput = true;
psi.WindowStyle = ProcessWindowStyle.Minimized;
psi.CreateNoWindow = true;
psi.Arguments = "/accepteula -s -i \\\\" + pingnaam + " cmd /c msg.exe * " + MessageToSend;
process.StartInfo = psi;
process.Start();
}

I'm trying to create a RAM Directory via imdisk in C#. Since the cmd command is something like: imdisk -a -s 512M -m X: -p "/fs:ntfs /q /y"
I looked up how to process cmd commands with C# and found several hints regarding ProcessStartInfo(). This class works almost the way I intend it to, but since imdisk needs administrator priviliges I'm kinda stuck. Even though the code block is executed without exceptions, I don't see any new devices within the Windows Explorer.
try
{
string initializeDisk = "imdisk -a ";
string imdiskSize = "-s 1024M ";
string mountPoint = "-m "+ MountPoint + " ";
string formatHdd = "-p '/fs:ntfs /q /y' ";
SecureString password = new SecureString();
password.AppendChar('0');
password.AppendChar('8');
password.AppendChar('1');
password.AppendChar('5');
ProcessStartInfo procStartInfo = new ProcessStartInfo();
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
procStartInfo.RedirectStandardError = true;
procStartInfo.FileName = "cmd";
procStartInfo.Verb = "runas";
procStartInfo.UserName = "Admin";
procStartInfo.Password = password;
procStartInfo.Arguments = initializeDisk + imdiskSize + mountPoint + formatHdd;
Process.Start(procStartInfo);
catch (Exception objException)
{
Console.WriteLine(objException);
}
I hope someone can give me a little hint, right now I'm out of ideas.
Well I solved my problem in a different way. Somehow it seems that imdisk didn't format the new RamDisk the way it should and therefor no disk were created. As soon as I deleted the formatting option the disk is created and needs to be formatted. Therefore I started another process and used the cmd command "format Drive:"
For anyone who is interested, my solution is as follows:
class RamDisk
{
public const string MountPoint = "X:";
public void createRamDisk()
{
try
{
string initializeDisk = "imdisk -a ";
string imdiskSize = "-s 1024M ";
string mountPoint = "-m "+ MountPoint + " ";
ProcessStartInfo procStartInfo = new ProcessStartInfo();
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
procStartInfo.FileName = "cmd";
procStartInfo.Arguments = "/C " + initializeDisk + imdiskSize + mountPoint;
Process.Start(procStartInfo);
formatRAMDisk();
}
catch (Exception objException)
{
Console.WriteLine("There was an Error, while trying to create a ramdisk! Do you have imdisk installed?");
Console.WriteLine(objException);
}
}
/**
* since the format option with imdisk doesn't seem to work
* use the fomat X: command via cmd
*
* as I would say in german:
* "Von hinten durch die Brust ins Auge"
* **/
private void formatRAMDisk(){
string cmdFormatHDD = "format " + MountPoint + "/Q /FS:NTFS";
SecureString password = new SecureString();
password.AppendChar('0');
password.AppendChar('8');
password.AppendChar('1');
password.AppendChar('5');
ProcessStartInfo formatRAMDiskProcess = new ProcessStartInfo();
formatRAMDiskProcess.UseShellExecute = false;
formatRAMDiskProcess.CreateNoWindow = true;
formatRAMDiskProcess.RedirectStandardInput = true;
formatRAMDiskProcess.FileName = "cmd";
formatRAMDiskProcess.Verb = "runas";
formatRAMDiskProcess.UserName = "Administrator";
formatRAMDiskProcess.Password = password;
formatRAMDiskProcess.Arguments = "/C " + cmdFormatHDD;
Process process = Process.Start(formatRAMDiskProcess);
sendCMDInput(process);
}
private void sendCMDInput(Process process)
{
StreamWriter inputWriter = process.StandardInput;
inputWriter.WriteLine("J");
inputWriter.Flush();
inputWriter.WriteLine("RAMDisk for valueable data");
inputWriter.Flush();
}
public string getMountPoint()
{
return MountPoint;
}
}
Doesn't cmd.exe need to have the /C command line option passed through to run a command passed through as an argument? May well be that cmd.exe is just ignoring what you're passing through in procStartInfo.Arguments because you haven't prepended "/C " onto the front of the Arguments.
I am developing a software that will list all the software install
in Computer
now i want to Uninstall it using my Program In C# by
calling the Uninstall Key of that software in
Registry Key
My Program Is
Like That But the Process Is Not Working
var UninstallDir = "MsiExec.exe /I{F98C2FAC-6DFB-43AB-8B99-8F6907589021}";
string _path = "";
string _args = "";
Process _Process = new Process();
if (UninstallDir != null && UninstallDir != "")
{
if (UninstallDir.StartsWith("rundll32.exe"))
{
_args = ConstructPath(UninstallDir);
_Process.StartInfo.FileName = Environment.SystemDirectory.ToString() + "\\explorer.exe";
_Process.StartInfo.Arguments = Environment.SystemDirectory.ToString() + "\\" + UninstallDir;
_Process.Start();
}
else if (UninstallDir.StartsWith("MsiExec.exe"))
{
_args = ConstructPath(UninstallDir);
_Process.StartInfo.FileName = Environment.SystemDirectory.ToString() + "\\cmd.exe";
_Process.StartInfo.Arguments = Environment.SystemDirectory.ToString() + "\\" + UninstallDir;

//string Path = ConstructPath(UninstallDir);
_path = ConstructPath(UninstallDir);
if (_path.Length > 0)
{
_Process.StartInfo.FileName = _path;
_Process.StartInfo.UseShellExecute = false;
_Process.Start();
}
}
Try this approach:
Process p = new Process();
p.StartInfo.FileName = "msiexec.exe";
p.StartInfo.Arguments = "/x {F98C2FAC-6DFB-43AB-8B99-8F6907589021}/qn";
p.Start();
Refer to this link: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/msiexec.mspx?mfr=true
HTH.
The problem with your misexec.exe code is that running cmd.exe someprogram.exe doesn't start the program because cmd.exe doesn't execute arguments passed to it. But, you can tell it to by using the /C switch as seen here. In your case this should work:
_Process.StartInfo.FileName = Environment.SystemDirectory.ToString() + "\\cmd.exe";
_Process.StartInfo.Arguments = "/C " + Environment.SystemDirectory.ToString() + "\\" + UninstallDir;
Where all I did was add /C (with a space after) to the beginning of the arguments. I don't know how to get your rundll32.exe code to work, however.
Your solution looks good, but keep a space before \qn:
p.StartInfo.Arguments = "/x {F98C2FAC-6DFB-43AB-8B99-8F6907589021} /qn";
Otherwise it wont work in silent mode.
