rstudio - Shiny application -- how to suppress function and rendering on launch? -

-

I have developed a shiny app with RStudio that takes input, searches for a look-up table, and Then returns a value. This is not searched until the user hits the submit button. However, upon launching, the app automatically gives and gives the first set of values ​​set before the lookup table. After this initial search, does the app really work as expected? Is it possible to stop this initial search (or have a default value) and only search when the submit button is pressed? I can not present the reproducible code, but here is the structure of my input (server.R) and my user interface (ui.R) code: 

  # server.r Snippet output $ Word & lt; # Rendertext ({predictWord & lt; - Input $ gm predict.function (predictWord) # User-defined functions in global.r file}) # ui.R Snippet TabPanel ("Word Forecasting", SidebarPanel (Text Input ("Village" , "Enter three words"), Submit Button ("Forecasting"), MainPanel ("Word Forecasting"), TextOptput ("Prophecy Ward")))    
 
 
 one way  action button  must be replaced by  submitButton  B The component will be a  if  statement is a simple example for displaying a number, of which only a few have been modified.  
  is required ( (Appendix "HeaderPanel", "ActionButton Test"), SidebarPanel (numericInput ("N", "N:", min = 0, max = 100, value = 50), br () , ActionButton ("goButton", "go!"), P ("Main Panel (.)), MainPanel (Verbatum Text Output (" Antiquity "), Server = Function (Input, Output K) {output $ nText & lt; - Depend on the render text (input) $ goButton if (input $ goButton> = 1) {# input $ n different (input $ n)}}}}})))   < Use divestment to avoid dependency on / div>

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...
