  • How ensure if java program uses UTF-8 encoding

    - by Nayn
    Hi, I recently discovered that relying on default encoding of JVM causes bugs. I should explicitly use specific encoding ex. UTF-8 while working with String, InputStynreams etc. I have a huge codebase to scan for ensuring this. Could somebody suggest me some simpler way to check this than searching the whole codebase. Thanks Nayn

  • C++ passing arguments to a program already running

    - by wyatt
    I'm reading through a tutorial on using voice commands to control applications and, in an example of controlling rhythmbox, it suggests commands such as the following can be executed: rhythmbox-client --play rhythmbox-client --pause Why does this not simply open a new instance of the program, and how can I emulate the functionality in my own programs? For example, how could I pass a string to a particular instance of a program? Thanks

Help me guys please... BTW... Could you tell me how can I see the exact query string that EF passes to Sql Server on db.SaveChanges() method?

    - by Kirzilla
    Hello, What is the fastes way to add string prefixes to array keys? was $array = array( '1' => 'val1', '2' => 'val2', ); needed $array = array( 'prefix1' => 'val1', 'prefix2' => 'val2', ); According to http://www.phpbench.com/ (see Modify Loop) I should use "for" statement, but probably there is more elegant way? Thank you.

  • C++ How fast is passing around objects?

    - by wndsr
    Assuming we are running a compiled C++ binary: Is passing around an int (e.g. function to function, or writing it into variables) slower than passing around structs/class objects like the following? class myClass { int a; int b; char c; vector d; string e; }

  • Include HTML file as embedded resource

    - by Stacey
    A followup to another question I did, I've done some more digging but I am still coming up dry. Is there any way to include .HTML/.ASPX files as 'embedded resources' into an ASP.NET MVC application? I've found lots of examples of using string resources, but never other files entirely.

  • C# setting case constant expressions, do they have to follow a specific order?

    - by Umeed
    Say I'm making a simple program, and the user is in the menu. And the menu options are 1 3 5 7 (i wouldn't actually do that but lets just go with it). and I want to make my switch statement using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace DecisionMaking2 { class Program { static void Main(string[] args) { Console.WriteLine("Please choose an option: "); string SelectedOpt = Console.ReadLine(); double Selection = Convert.ToDouble(SelectedOpt); double MenuOption = (Selection); switch (MenuOption) { case 1: Console.WriteLine("Selected option #1"); break; case 2: Console.WriteLine("Selected option #3"); break; case 3: Console.WriteLine("Selected option #5"); break; case 4: Console.WriteLine("Selected option #7"); break; default: Console.WriteLine("Please choose from the options List!"); break; } } } } would that work? or would I have to name each case constant expression the option number I am using? I went to the microsoft website and I didn't quite pick up on anything i was looking for. . Also while I have your attention, how would I make it so the user chooses from either option and because I don't know which option the user will select " double MenuOption = " could be anything, whatever the user inputs right? so would what I have even work? I am doing this all by hand, and don't get much lab time to work on this as I have tons of other courses to work on and then a boring job to go to, and my PC at home has a restarting issue lol. soo any and all help is greatly appreciated. p.s the computer I'm on right now posting this, doesn't have any compilers, coding programs, and it's not mine just to get that out of the way. Thanks again!

    - by baal80
    I'm working on a 64-bit Windows and my applicaiton runs with elevated privileges. I have a problem with the following very simple piece of code: myKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run"); if (myKey != null) { string[] HKLMvaluenames = myKey.GetValueNames(); } But for some reason HKLMvaluenames array is populated with values from the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run Is there a way around this problem?

  • Char * reallocation in C++

    - by JTom
    Hi, I need to store a certain amount of data in the "char *" in C++, because I want to avoid std::string to run out of memory, when exceeding max_size(). But the data comes in data blocks from the network so I need to use reallocation every time I get the data block. Is there any elegant solution for char * reallocation and concatenation in C++?

  • Apply Xslt on in-memory Xml and returning in-memory Xml

    - by Jan Willem B
    I am looking for a static function in the .NET framework which takes an XML snippet and an Xslt file, applies the transformation in memory, and returns the transformed XML. I would like to do this: string rawXml = invoiceTemplateDoc.MainDocumentPart.Document.InnerXml; rawXml = DoXsltTransformation(rawXml, @"c:\prepare-invoice.xslt")); // ... do more manipulations on the rawXml Alternatively, instead of taking and returning strings, it could be taking and returning XmlNodes. Is there such a function?

  • scaffold does not update view

    - by doemsche
    Hi there I have a question to the following procedure: script/generate scaffold product title:string description:text db:migrate #then I generate a migration which adds a column description to the table products and migrate the db again. My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour? I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient. Thanks in advance for any help!

  • Storing a type in C++

    - by perimosocordiae
    Is it possible to store a type name as a C++ variable? For example, like this: type my_type = int; // or string, or Foo, or any other type void* data = ...; my_type* a = (my_type*) data; I know that 99.9% of the time there's a better way to do what you want without resorting to casting void pointers, but I'm curious if C++ allows this sort of thing.
