Re: sendkeys to open the command window

Vinki,

If you want to have an application interact with a service, you should
use remoting or WCF to make calls into your service. You can't access the
service directly to make calls.

I will uncheck the interacting with desktop option. All I am trying to do
is
from my windows application. I am trying to call a method that exists in
the
window service. That method needs to start a process and use sendkey to
start
the process.

Vinki,

Why are you trying to interact with the desktop from a service? What
exactly do you need to do? You shouldn't be interacting with the desktop
from a service, because you can have multiple desktops running on a box
at
any one time (due to terminal services) or none at all (if no one is
logged
in interactively).

public void sendKeysTest()

Process myProcess = Process.Start(@"C:\winnt\system32\cmd.exe");

SetForegroundWindow(myProcess.Handle);

I have this code in my windowservice. Option to interact with desktop
in
window service is also checked. When I click a button on the front end.
Inside the button click event, I call this method sendKeysTest, and
sendKeysTest is defined inside the window service. This program runs
fine
and
I can see cmd in my task manager that it is started, but I don't see
the
cmd
window. Is there any way I can see the cmd window. This code runs fine
when I
run this code in windows form.

private void Button1_Click(object sender, System.EventArgs e)
{
try
{

runner.sendKeysTest();
}
catch(Exception ex)
{
string x = ex.Message;
}

}

Thanks,

Any help will be appreciated.
