c++ - Compilation error when trying to use vector -

-

I try to compile this code, but I get an error: 

 < Code> #include & lt; Sstream & gt; # Include & lt; Vector & gt; Int main () {std :: vector & lt; Std :: ostringstream & gt; V; V.reserve (100); Return 0; }   
 The error message says something about being unable to create  ostringstream  as a default when compiling with GCC or rub I actually Can not make sense of error message  Reserved ()  tries to make anything? Here's the code:   
 
 
 When calling  reserved , the vector ends With enough space for 100 elements, it means  reserved  should have the possibility of copying or increasing everything.  
 Because the streams are non-copyable, for this reason, they can not be stored in standard containers before C ++ 11. C +11 11, currents can be transferred, they can be made to work properly in standard containers. The missing piece here is that libstdc ++ has not implemented the currently running currents. It's with Liby ++  
 Expect to see in this work.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
