call

Is there anyway to do the below without delayed expansion (one line, broken for readability)? %comspec% /v:on /c %windir%\System32\reg.exe import c:\temp\test.reg & if !errorlevel! neq 0 pause If it were an echo, I know that call can be used, but doesn't seem to be available for use with the if . Andriy M One way is to use this older syntax: %comspec% ... & if errorlevel 1 pause In this case, a special variant of if statement is used, one that tests the current errorlevel state. Another option might be this: %comspec% ... || pause The || command delimiter is roughly equivalent to & if

I have a web application made with Spring that runs on Tomcat. On the same machine there is a normal Java application. I would like to execute the Java application by calling it from the web server, but i want to make it so the application won't use the server's resources (it involves the training of a classifier so it may take up a lot of resources and time) and it must not hang the server (so it must be called asynchronously). Is there any way to do that? You have two options. Start a separate JVM instance by doing a exec and using a java command. Spawn a new thread - this will use server's

i have the following code in a module called code_database.py class Entry(): def enter_data(self): self.title = input('enter a title: ') print('enter the code, press ctrl-d to end: ') self.code = sys.stdin.readlines() self.tags = input('enter tags: ') def save_data(self): with open('entry.pickle2', 'ab') as f: pickle.dump(self, f) in idle the class-defined methods work fine: >>> import code_database >>> entry = code_database.Entry() >>> entry.enter_data() enter a title: a enter the code, press ctrl-d to end: benter tags: c >>> entry.title 'a' >>> entry.code ['b'] >>> entry.tags 'c' >>> however

I'm trying to figure out how to change some value after each call of the object. I thougt that call () function is executed after each call. This should be a simple counter class which decreases value attribute after being called. class counter(): def __init__(self,value): self.value = value def __call__(self): self.value -= 1 count = counter(50) print count.value print count.value >> 50 >> 50 <-- this should be 49 What am I doing wrong? jedwards If you're not committed to classes, you could use a function and abuse using mutable-types-as-default-initializers: def counter(init=None, container=

When using the telprompt intent on iOS like window.location = 'telprompt://' + phoneNumber the user gets prompted to either call the number or cancel. Is there a way to know which of the two actions the user has made? Looking at the PhoneGap docs the "startcallbutton" event is only supported on BlackBerry. All you can do is listen for the pause event. document.addEventListener("pause", yourCallbackFunction, false); This event will be fired when there is an incoming call or starting a call. or you could look into the phone listener plugin and try to write it for iOS https://github.com/devgeeks

How would I load a chunk of Lua code as a char and run it using this function? If not, what other function can I use and how does lua_load() work? Use luaL_dofile and luaL_dostring to load and run Lua code. Read their definitions in lauxlib.h to see how these are implemented in terms of lower-level primitives. To learn how lua_load works, read the code of luaL_loadfile and luaL_loadstring . 来源： https://stackoverflow.com/questions/4272231/how-does-lua-load-work

In python, calling XML-RPC methods involves invoking methods on a proxy object: from xmlrpclib import ServerProxy print ServerProxy('https://example.com/rpc').api.hello_there('John') In some other languages, like perl, you pass your method name as a method parameter. use Frontier::Client; $p = Frontier::Client->new(url => 'https://example.com/rpc'); $result = $p->call('api.hello_there', 'John'); print $result; Is there a way to invoke XML-RPC methods by name, as strings, in Python? Just use getattr , as with any Python object. func = getattr(ServerProxy('https://example.com/rpc'), "api.hello
