I'm starting playing with QWebView in PySide. I can load the HTML in the web view and see it, although I may not have to load the page online or set the URL. Here's my example: Import from PySide.QtCore import from * import system * from PySide.QtWebKit import * app = QApplication (sys.argv) web = QWebView () Web.setUrl (QUrl ("https://www.google.com")) web.show () sys.exit (app.exec_ ()) All I get is this Is there a nice empty white window anyone know what is missing? Maybe you are behind a proxy I have experienced the same behavior and a proxy for the application Has helped set up. PySide.QtNetwork Import QNetworkProxy Proxy = QNetworkProxy () Proxy .set Type (QNetworkProxy.Socks5Proxy) ; Proxy.setType (QNetworkProxy.HttpProxy); Proxy.setHostName ("*********"); Proxy.setPort (****); QNetworkProxy.setApplicationProxy (Proxy);

I have a visual object and I to make such a line: ContactsVORowImpl Person = (contact VORowImpl) getContactsVO (). CreateRow (); Then I leaves the assigned some properties went lines formed, which overlooked the others (intentionally): person.setFirstname ( "Firstname"); //person.setLastname (""); person.validate (); I get a validation error complaint because last name is empty . Then I commit without any entry , line in the visual object: getDBTransaction (). Commit (); Here I Last Name The following exception to be null: exception class: class oracle.jbo.AttrValException, Message : JBO-27014: Attribution Last Name is required in ContactOo.

I'm new to R. I have to use POSTagger in my code. I am using OpenNLP when attempting the following sample code (in the sample r file): Library ("NLP") library ("OpenNLP") S & lt; - "Cache Witchhen, 61 year old, one on board", "Unqualified Director will be included as Nov. 29, \ N", "President of Mr. Vernon Elsevier NV", "Dutch Publishing Group"), Fall = "") S & lt; - as.String (s) sent_token_annotator & lt; - Maxent_Sent_Token_Annotator () a1 & lt; - The interpretation (s, sent_token_annotator) is [a1] and run this code from the R console (using the source ("sample .r")) I get the following error: error in as.data.frame.default (x [[i]], alternate = TRUE: can not force a data.frame class "c" ("Simple_POS_Tag_Annotator", "interpreter" ) " after the output of traceback () is in order: 14: stop (gettexf (" "data" Can not f...

It is possible to get an error message in capturing the C # (or window service that was written with C #) / P> string input = console Readline (); While (Input! = "Q") {try {double result = 10 / int.Parse (input); Console.light line ("+ input +" divided by "and result is" + result); } Hold (exception) {Console.WriteLine ("error, please try again"); } Finally {input = Console.ReadLine (); }} This was created for the ".exe" program. If I input characters ("A", "B", "C") or zero, then the program will show the message "Error, Please try again" so that I should know the error message. I do not want to edit the code. I need a tool to detect all the errors in the program. Thank you for your help. You want to print the message property of your own Replace hold with: hold (exception e) {Console.WriteLine ("An exception occurred:" + E. Message); }

I have many files with code, I have to search different keywords along with the function. Currently I'm using the keyword "grep-i -r" which searches for "Linux" in search. However, I need to increase the pace of search to reduce time. I have also heard of the Boer-Moore algorithm which is a fast detector but I am not expecting the results I have achieved. So I am very excited to hear your comments and solutions. You should try ack (). It's designed as a fast search tool for code. If you want the ability to take your code into the language syntax account (the difference between the function and symbols) you should try it.

After itemprop = "text"> I want to insert a row-column into a CSV Ruby, and in the subsequent operations, on the sequential lines of a single column Performing a data like array [startrow..endrow] [3] .reduce (: +) something like I have a CSV file In a specific cell, such as: array [somerow] [somecolumn] / 2 but me ". .. any underlying conversion of the string Only get the "integer" error when I try to reference a subset Edit: I do the CSV import using the following, which correctly appears to change the number of strings I am: array = CSV.read ('spy_very_short.txt',: header = & gt; true, converters: all) when I run the suggestion test array [somerow] [somecolumn] .class I get back "float". without knowing more about what is returned (I think it always represents a number Is a string), I think you need to convert the string to something you can do with it: value = array [somerow] [somecolumn] print ...

I'm trying to make a really basic iOS app using Swift - this is my first time to do this Although most of this is actually straight forward, my app has a complete nightmare to speak to my API or to any site in general. I am using this code, and especially the code that is causing the error: NSURLConnection.sendAsynchronousRequest (request, queue: line, ending handler : {(Response: NSURLResponse !, Data: NSData !, Error: NSError) -> Zero (NSString (data: encoding: NSUTF8StringEncoding) in println!)}) It is the 'NSString (data: data, encoding: NSUTF8StringEncoding)' those errors as many tutorials as I can find, so I have returned the same problem. I have an 'EXC_BAD_INSTRUCTION' error: EXC_1386_INVOP, sub-code = 0x0 (which gives me a solution: NSURLErrorDomain - Code: 4294966291 I have not been led ... I feel that I have not done anything right in my establishment, or something should be running in my priorities, or some of those lines, unlik...
