I am developing a C# program to remotely uninstall an application. It works fine but the problem is that it does not list all of the installed products on a particular selected computer.
The code for listing the installed product using WMI is :
void ListAllProducts()
{
try
{
ConnectionOptions connection = new ConnectionOptions();
connection.Username = Connect.UserName;
connection.Password = Connect.Password;
connection.Authority = "ntlmdomain:MSHOME";
ManagementScope scope = new ManagementScope("\\\\"+ Connect.MachineName +"\\root\\CIMV2", connection);
scope.Connect();
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_Product");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
System.Threading.Thread.Sleep(5000);
foreach (ManagementObject queryObj in searcher.Get())
{
listBox4.Items.Add(queryObj["Name"].ToString());
listBox2.Items.Add (queryObj["Name"].ToString ());
listBox1.Items.Add(queryObj["IdentifyingNumber"].ToString());
listBox3.Items.Add(queryObj["Version"].ToString());
}
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
}
The code for uninstalling all product is :
void UninstallProduct()
{
try
{
ConnectionOptions connection = new ConnectionOptions();
connection.Username = Connect.UserName;
connection.Password = Connect.Password;
connection.Authority = "ntlmdomain:MSHOME";
ManagementScope scope = new ManagementScope("\\\\"+Connect.MachineName +"\\root\\CIMV2", connection);
scope.Connect();
ManagementObject classInstance = new ManagementObject(scope, new ManagementPath ("Win32_Product.IdentifyingNumber='"+listBox1.Text +"',Name='"+listBox2.Text+"',Version='"+ listBox3.Text+"'"),null);
// no method in-parameters to define
// Execute the method and obtain the return values.
ManagementBaseObject outParams =
classInstance.InvokeMethod("Uninstall", null, null);
// List outParams
MessageBox.Show ("Uninstallation Starts");
}
catch(ManagementException err)
{
MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message);
}
}
Please help me out to list all the products installed on the selected machine and to uninstall it without the consent of the user of that selected machine.
I believe your question relates to knowing which applications are installed on a remote machine. Once you know that, you can use your code to uninstall them. With that being the case, here is a link to an article on how to list all of the applications (with their uninstall information) on a remote computer:
http://mdb-blog.blogspot.com/2010/12/c-check-if-programapplication-is.html
The WMI Win32_Product only represents products that are installed by Windows Installer. To get a list of all installed products, you need to enumerate the subkeys of the SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall registry key. To do this remotely, you can use the WMI registry class StdRegProv class. TechNet includes sample scripts that show how this can be done, and which you can adapt to your particular needs:

I am trying to create an application that uses WMI to retrieve information about a computer on my local network. When I run it, I get an access denied error. Here is the code:
private void GetHDDdetails()
{
ConnectionOptions options = new ConnectionOptions();
options.Username = "username";
options.Password = "password";
options.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope oMs = new ManagementScope("\\\\remoteHostName\\root\\cimv2", options);
ObjectQuery oQuery = new ObjectQuery("SELECT Size FROM Win32_DiskDrive");
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery);
ManagementObjectCollection oCollection = oSearcher.Get();
foreach (ManagementObject obj in oCollection)
{
hddBox.Text = obj["Size"].ToString();
}
}
I have replaced some of the info above, such as user name and password, with placeholders for this post.
Some of the things I have tried is this: Disabling firewall on both machines, making sure TCP NetBIOS service and RCP and WMI services are running on both. The account I am using is an administrator on the local computer. Everything I have found online tells me to check these, but it is obviously something else.
If someone can point me in the right direction, that would be great.
Please check using wbemtest that you can access the information from remote machine. And i hope you are replacing remoteHostName properly.
And make changes to authentication level, if you can.
scope.Options.EnablePrivileges = true;
scope.Options.Authentication = AuthenticationLevel.PacketPrivacy;
I want to open process pon remote machine, this remote machine is inside local network.
I try this command and in the remote machine nothing happen, this user that i connect with have administrators rights.
Both machines running Windows 7
static void Main(string[] args)
{
try
{
//Assign the name of the process you want to kill on the remote machine
string processName = "notepad.exe";
//Assign the user name and password of the account to ConnectionOptions object
//which have administrative privilege on the remote machine.
ConnectionOptions connectoptions = new ConnectionOptions();
connectoptions.Username = #"MyDomain\MyUser";
connectoptions.Password = "12345678";
//IP Address of the remote machine
string ipAddress = "192.168.0.100";
ManagementScope scope = new ManagementScope(#"\\" + ipAddress + #"\root\cimv2", connectoptions);
//Define the WMI query to be executed on the remote machine
SelectQuery query = new SelectQuery("select * from Win32_process where name = '" + processName + "'");
object[] methodArgs = { "notepad.exe", null, null, 0 };
using (ManagementObjectSearcher searcher = new
ManagementObjectSearcher(scope, query))
{
foreach (ManagementObject process in searcher.Get())
{
//process.InvokeMethod("Terminate", null);
process.InvokeMethod("Create", methodArgs);
}
}
Console.ReadLine();
}
catch (Exception ex)
{
//Log exception in exception log.
//Logger.WriteEntry(ex.StackTrace);
Console.WriteLine(ex.StackTrace);
}
}
you are not opening a process with that code but you are enumerating all the running process named "iexplore.exe" and close them.
I think an easier, better way is to use SysInternals PsExec or the Task Scheduler API
If you want to use WMI your code should look like this:
object theProcessToRun = { "YourFileHere" };
ManagementClass theClass = new ManagementClass(#"\\server\root\cimv2:Win32_Process");
theClass.InvokeMethod("Create", theProcessToRun);
----------In reply to your comment------------------
First of all you need to change your attitude and approach to coding and read the code that your are copy/pasting.
Then you should study a little more about programming languages.
No I will not write the code for you. I gave you an hint to point to the right direction. now it is your turn to develop it. Have fun!!
This is script that i did for my company before this using vbs script. can search the net to convert it to C# or etc. Fundamental of the steps and how to start a service using WMI. Have a nice coding and have fun.
sUser = "TESTDomain\T-CL-S"
sPass = "Temp1234"
Set ServiceSet = GetObject("winmgmts:").ExecQuery("Select * from Win32_Service where Name = 'netlogon'")
For Each Service In ServiceSet
Service.StopService
Service.Change "netlogon",Service.PathName, , ,"Automatic",false,sUser,sPass
Service.StartService
Next
Set Service = Nothing
Set ServiceSet = Nothing
We have 6 Citrix Servers. I'm trying to find out if Remote Logons are enabled/disabled.
I plan to put this onto of a webpage to display and green icon if they are or red if they aren't.
I've managed to connect to the machines and pull operating system information etc.. However when i try and connect to view the TerminalServiceSetting information.. i get an Invalid Class error.
Here is my code.
ManagementScope scope = new ManagementScope("\\\\MACHINENAME\\ROOT\\cimv2");
scope.Connect();
//create object query
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_TerminalServiceSetting");
//create object searcher
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(scope, query);
//get collection of WMI objects
ManagementObjectCollection queryCollection = searcher.Get();
//enumerate the collection.
foreach (ManagementObject m in queryCollection)
{
// access properties of the WMI object
Label1.Text = m["AllowTSConnections"].ToString();
}
If anyone can shed some light on it that would be great.
Thanks
Update:
I have now found the code (i think) that checks to see if remote connections are enabled or disabled.
ManagementScope scope =
new ManagementScope("\\\\MACHINENAME\\root\\CIMV2\\TerminalServices",con);
scope.Options.EnablePrivileges = true;
scope.Options.Authentication = AuthenticationLevel.PacketPrivacy;
scope.Options.Impersonation = ImpersonationLevel.Impersonate;
scope.Connect();
//create object query
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_TerminalServiceSetting");
//create object searcher
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(scope, query);
//get collection of WMI objects
ManagementObjectCollection queryCollection = searcher.Get();
//enumerate the collection.
foreach (ManagementObject m in queryCollection)
{
if (m["AllowTSConnections"].ToString() == "1")
{
Redicon.Visible = false;
}
else
{
Greenicon.Visible = false;
}
}
However when i run the code i get returned "1".. which is fine. However if i deny remote logins on the server and re run the code it stays at 1..
Any ideas?
You need to be sure that the server provide the TerminalServiceSetting information. WMI uses unmanaged code because not all servers and their configurations provide all information.
You can use Mgmtclassgen to generate managed code and at the same time make sure that the server provides the information.
Sorted!!!
I was looking up the wrong field.
the correct one is :
Label1.Text = "Remote Connections: " + m["Logons"].ToString();
I have the IIS service running on Windows Server 2008 and i want to reset it from my windows 7 machine .
How do i reset IIS remotely using C#.Net code?
I tried using Microsoft.Web.Administration, but it doesn't accept remote server details to connect to .Any other API's that can be used for this purpose ?
If you have a specific web site name, you can use the WMI to stop and start that web site. If it's IIS as a whole, I'm sure there is something in the IIS WMI provider for doing this. Here I'm using WebAdministration to manage a web site under IIS, but there's also MicrosoftIISV2. Google for WmiExplorer, there are some good ones out there.
var connOptions = new ConnectionOptions();
connOptions.Authentication = AuthenticationLevel.PacketPrivacy;
// if you want to connect as someone other than logged in user
//connOptions.Username = username;
//connOptions.Password = password;
var scope = new ManagementScope("\\localhost\WebAdministration", connOptions);

I have been writing an application to get the details of remote machine like OS Name, Logon User Name etc using WMI Classes.
In our network we have machines with Windows XP, Windows Vista Windows 7.
I am able to get the informations for all windows 7 and windows vista machines.
But the problem here is i am not able to get the informations for windows XP machines.
Every time i am getting the following exception
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I have gone through the net but no help. I have done all the steps mentioned in the following link
http://support.microsoft.com/kb/875605.
But no luck still i am not able to solve the problem.
I have domain username with administrator privilages.
Below is the code that i have used. (C#)
private void GetRemoteComputerInfo(string compName)

ManagementScope msc;
if (compName == Environment.MachineName)
msc = new ManagementScope("\\\\" + compName + "\\root\\cimv2");
else
msc = new ManagementScope("\\\\" + compName + "\\root\\cimv2", connOptions);
msc.Connect();
ManagementClass mc = new ManagementClass("Win32_ComputerSystem");
mc.Scope = msc;
//collection to store all management objects
ManagementObjectCollection moc = mc.GetInstances();
if (moc.Count != 0) {
foreach (ManagementObject mo in mc.GetInstances()) {
Console.WriteLine(string.Format("\nMachine Make: {0}\nMachine Model: {1} System Type: {2} Host Name: {3} Logon User Name: {4}{5}",
mo["Manufacturer"].ToString(),
mo["Model"].ToString(),
mo["SystemType"].ToString(),
mo["DNSHostName"].ToString(),
mo["UserName"].ToString(),
Environment.NewLine));
}
}
}
catch (Exception e) {
Console.WriteLine("{0}: {1}", e.GetType().Name, e.Message);
}
}
Please help me to solve the problem.
Prasad, in the past i have a similar issue related to the WMI DCOM permission, and was resolved following the instructions of these these two links.
