(Please, can somebody verify if I'm actually subscribed (with the address
on this mail) to all the lists? Here I've made some changes on the
imago.ro computers to leave one of them free to install OPENSTEP on
it; but now I'm not sure if I've moved all the users well...)
I'm trying to get an istance of a running application to see if it
isRunning and to set the value of the "Status:" label of the Processes
window.
Im doing so:
NS_DURING
{
theApp = [NSConnection
rootProxyForConnectionWithRegisteredName: appName
host: @""];
}
NS_HANDLER
{
theApp = nil;
}
NS_ENDHANDLER
if (theApp != nil)
{
if ([theApp isRunning])
{
appStatus = @"running";
}
else
{
appStatus = @"stopped";
}
}
but i get "Uncaught exception NSGenericException, reason: method isRunning
not implemented".
The interesting think is that if I implement in an app - (BOOL)isRunning
(returning YES), all works!
