C: exec to my own exe file -

-

I am using linux for try and exec to run a different child process in the basic process.

The I Ps can execute the child process to run the command. 

  int x = fork (); If (x == 0) {execl ("/ bin / ps", "ps", NULL); }   
 However, as soon as I try to run the .exe file which I have created from my C file in this way  GCC-V test.c -o test. Exe . By running this code:  
  int x = fork (); If (x == 0) {execl ("/ desktop / test", "test.exe", NULL); }   
 Then nothing happens if I print the statement above  execl  then it gives -1.  
 Will someone tell me what's going on?  
 Some notes:  
     
  1.  The test.exe file (made from my source code) icon shows a window icon (why, and this is the problem?)  
  2.  
  3.  
  4.   
     
     
     The problem is: Is that your desktop folder is  ~ / on the desktop / . Tild means your  home  folder.

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...
