Hi,

i'm using the following code to run a copied file from Command line on remote machine.
That works well but my problem is that the return code is instant 0 also if i try a command which is not working.

Here is the code:

C#

ConnectionOptions connOptions = new ConnectionOptions();
connOptions.Impersonation = ImpersonationLevel.Impersonate;
connOptions.EnablePrivileges = true;

ManagementScope manScope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", reachablehost), connOptions);
manScope.Connect();


ObjectGetOptions objectGetOptions = new ObjectGetOptions();
ManagementPath managementPath = new ManagementPath("Win32_Process");
ManagementClass processClass = new ManagementClass(manScope, managementPath, objectGetOptions);



ManagementBaseObject inParams = processClass.GetMethodParameters("Create");


inParams["CurrentDirectory"] = @"C:\Windows\Temp\swdeploy";
inParams["CommandLine"] = @"cmd /c setup.exe /silent";

ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);


Cursor = Cursors.Default;

if (outParams["returnValue"].ToString() == "0")
{
MessageBox.Show("Die Installation wurde erfolgreich abgeschlossen", "Installation erfolgreich", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
MessageBox.Show("Die Installation wurde mit Code " + outParams["returnValue"].ToString() + " abgeschlossen.\n\nFehlertext:\n\n" + outParams["returnText"].ToString(), "Installationsfehler", MessageBoxButtons.OK, MessageBoxIcon.Error);
}

Can someone help me here?

What I have tried:

if i use a:

cmd /c start /wait

it's also not waiting to finish.

Thanks in Advance

Implies a deadlock. You should poll if you want to know what an other process is doing; or use a callback.

Have you tried adding a watcher, as described in this documentation?

It returns a 0 because this is a "fire and forget" process. The process of launching a remote process only returns a value for the process of launching the process. It does NOT wait for the launched process to finish executing and return that exit code.

There is no in-built method to "Wait for exit" on a Win32_Process, so you can then get the exit code. You have to write a wrapper around the Win32_Process.Create call to implement that functionality.

Fortunately for you, someone already did that. You can find the code here[^].
