Guru's, what is wrong with this code please?

[trint]

Here is the error:
An unhandled exception of type 'System.Management.ManagementException'
occurred in system.management.dll
Additional information: Not found

here is the code:

string printerName = "";
foreach (ManagementObject printer in searcher.Get())
{
printerName = printer["Name"].ToString().ToLower();
if (printerName.Equals(@"\\web1\shipping1"))
{
//Console.WriteLine("Printer = " + printer["Name"]);
error occurs here>>> if
(printer["WorkOffline"].ToString().ToLower().Equals("true"))
{

//Class1.printerStatus = printer;
// printer is offline by user
// Console.WriteLine("Your Plug-N-Play printer is not
connected.");
}
else
{
// printer is not offline
// Console.WriteLine("Your Plug-N-Play printer is connected.");
}
}
}

Trint,

Catch the ManagementException and examine the exception instance
to get more info.

Should be:

if(bool)printer.Properties["WorkOffLine"].Value = true)
....
else

 

[Keith M]

Should be:

if(bool)printer.Properties["WorkOffLine"].Value = true)
...
else

<Pedant mode on>

if( (bool)printer.Properties["WorkOffLine"].Value == true)


Extra opening brace. 2 'equals'

<Pedant mode off>
