• How can I prevent anyone from holding a reference to an object in C#

  - by floatingfrisbee

  I have a class like this internal class Report { public Company TargetCompany { get; private set; } .... // other stuff } I do not want any one to be able to do this Report r = GetReport(); Company c = r.TargetCompany; but instead always use r.TargetCompany when they want access to the Company variable. Is that possible? Does that even make sense?

So, may I ask when is the static class variable initialized during runtime?

• [PowerShell] Input encoding

  - by Andy

  Hi! I need to get output of native application under PowerShell. The problem is, output is encoded with UTF-8 (no BOM), which PowerShell does not recognize and just converts those funky UTF chars directly into Unicode. I've found PowerShell has $OutputEncoding variable, but it does not seem to affect input data. Good ol' iconv is of no help either, since this unnecessary UTF8-as-if-ASCII = Unicode conversion takes place before the next pipeline member acquires data.

• How do I get the file size of a large (> 4 GB) file?

  - by endeavormac

  How can I get the file size of a file in C when the file size is greater than 4gb? ftell returns a 4 byte signed long, limiting it to two bytes. stat has a variable of type off_t which is also 4 bytes (not sure of sign), so at most it can tell me the size of a 4gb file. What if the file is larger than 4 gb?

• What .NET serializers have fixed size output for a given class?

  - by Jader Dias

  XML based serializers have variable size output for a given class. I can't use them to append data to my Memcached list, since I won't be able to retrieve that information later. But if I knew my serializer produced a fixed size output (N bytes), I could retrieve my data by splitting my list in N bytes chunks and then deserializing those chunks individually. I have created my own serializer for my class, but what other serializers I could use?

• javascript instanceof get type from string name

  - by dcp

  Let's say I have this (assume the name variable is "receiver"): if (!(receiver instanceof com.HTMLReceiver)) { throw new com.IllegalArgumentException( name + " is not an instance of com.HTMLReceiver."); } I'd like to factor this code out into a common method so I could call it like this: Helper.checkInstance(receiver, "com.HTMLReceiver"); But I don't know of a way to convert the com.HTMLReceiver from a string to its actual type so I can use instanceof on it. Is there a way?

• How to do an if statement on a function in PHP?

  - by Bruce

  I just realized that you can't just use an if statement on a function, for example this doesn't work: function sayHello() { echo "Hello World"; } if(sayHello()) echo "Function Worked"; else echo "Function Failed"; I also saw that a function can't be put as the value of a variable. So how can I do an if statement to check if a function has executed properly and display it to the browser?

• Is it more efficient (Performance) to store the CFC in application variables OR instance the CFC on the page call?

  - by Mitchell Guimont

  Hello, I'm working on a ColdFusion dynamic website. For this website, there are a lot of CFCs and a lot of functions within each CFC. Would it be more efficient to store an instance of the CFC in an application variable, then to instance each CFC separately on each page load. For each page, at most 2 separate CFCs get called. I'm also interested in how performance will be effected when requests increase (Stress). Thanks!
