Hello all,

I'm new here and it's a first time that i ask for help to the community. I'm also new in C sharp but i try to manage and learn on the way.

I would like to have some help to understand how to write a Process for windows with wich i can communicate with my winform.

i made an winform application which permit me to retrive some data from Active directory and also some other data from computers on the network "using powerShell" and a AD class.

For some reasons i can't grab a correct information about ex: shared Printers, cose the PowerShell give me a output of the computer printers, not user printers. It was a simple exemple.

so i decide to write a Process wich i want to upload and install on a remote computer, till here i can manage that.

what i would like to understand and if you can show me a little exemple, it's how to add some functions to this process and get the output of this function back to my Winform.

as exemple:

1.in my Winform a make a remote call to the process and ask him to give me the list of all printers installed.
2. show the output in a lisbox for exemple.

I would like to tell you thank you in advance for you help

We can abstract the question to "how do I get data from PC1 to PC2". The recommendation would be to look into WCF, but any type of exchange-mechanism would do- there's examples on communicating using sockets, but it'd even be possible using simple files.

Are the computers on the same LAN? If yes, I'd go for a simple socket Smile | :)

Thank you for response

Yes all Computers are nearly on the same network inside a Active directory.

it's about 9K of computers.

Make that a multithreaded client/server, based on TCP/IP. Alternatively, you can write files to an UNC-share - might be easier to code, will be a bit harder to maintain.

There's a client/server example on MSDN[^]. Be sure to check out the hyperlinks at the bottom of the page.

Thanks for this link, i already read this article, based on this, as i can understand is a console based server/client.

how i can whrite a simple command for server or client to get infos about printers.

for example i use this peace of code to retrieve local printers on a remote computer

private void GetPrinters()
        {

            string strServer = "\\\\" + this.textBox20.Text; //if the computer is local machine, use the "." instead
            ConnectionOptions options = new ConnectionOptions();
            options.Username = "xxxx";
            options.Password = "xxxxx";
            options.Authority = "NTLMDOMAIN:consilium";

            ManagementScope myScope = new ManagementScope(strServer + "\\root\\cimv2", options);
            SelectQuery oQuery = new SelectQuery("SELECT * FROM WIN32_Printer");
            ManagementObjectSearcher oResults = new ManagementObjectSearcher(myScope, oQuery);

            //Iterate through printers...
            foreach (ManagementObject oItem in oResults.Get())
            {
                string strPrinterName = oItem.Properties["DriverName"].Value.ToString();
                listBox2.Items.Add(strPrinterName.ToString().ToUpper());
               // Console.WriteLine(strPrinterName);

            }
        }

i would like to execute this code on a remote computer and get the data back to my winform.

thank you in advance
