Using WMI To query for App-V Packages

Here's a bit of code to query WMI for App-V Packages:

string root = "root/microsoft/appvirt/client";

ManagementPath path = new ManagementPath(root);

ManagementScope scope = new ManagementScope(path);

// Try and connect to the remote (or local) machine.

try

{

scope.Connect();

}

catch (ManagementException ex)

{

// Failed to authenticate properly.

return "Failed to authenticate: " + ex.Message;

//p_extendederror = (int)ex.ErrorCode;

//return Status.AuthenticateFailure;

}

catch (System.Runtime.InteropServices.COMException)

{

// Unable to connect to the RPC service on the remote machine.

return "Unable to connect to RPC service";

//p_extendederror = ex.ErrorCode;

//return Status.RPCServicesUnavailable;

}

catch (System.UnauthorizedAccessException)

{

// User not authorized.

return "Error: Unauthorized access";

//p_extendederror = 0;

//return Status.UnauthorizedAccess;

}

ManagementScope wmiScope = scope;

ObjectQuery oq = new ObjectQuery("Select * from Package");

ManagementObjectSearcher searcher = new ManagementObjectSearcher(wmiScope, oq);

foreach (ManagementObject queryObj in searcher.Get())

{

ListManagementObject> appvPackages = new ListManagementObject>();

appvPackages.Add(queryObj);

}

You now have a generic List of Managementobjects that contains all sorts of information about the App-V packages.

Here's an example what kind of information is in one ManagementObject:

As you can see, almost everything you need to know is in here.

Not Everything! But I will blog about that later...
