Microsoft Developer Network https://msdn.microsoft.com/en-us/default.aspx . It used to be really bad, especially with the C/C++ languages, hard to figure …  |

 | You would essentially need a deep copy clone of the array. Array only has a shallow copy though, so you would need to find some code that allows for deep copying. This would cause overhead if you were doing it a lot though. Arrays are pass by reference to prevent …  |
| | Just curious what kind of application needs to choose one of 50 doubles without going over? Is this some kind of guessing game? |

 | Re: Help with Code The toString method does not get overridden enough, and is good for displaying your books. Just override your own version which displays the variables you want displayed. Then you can simply pass the object you want displayed directly to System.out.println(obj) and it will print in string form the object. Here …  |
| | So, I am trying to get a query working that finds a certain flash drive attached to my computer and selects it's DriveInfo object. I am having trouble because on my system when I call the VolumeLabel property of one of my DriveInfo objects it throws an exception (IOException) because … |
| | Do you mean the first few bytes of a file, or the hash of the file? If you mean the hash, you will need to use a **hash algorithim** which is probably already implemented in the java API like **sha1, sha12, md5**, etc. The reason I bring it up is … |
| | So I am working on an old project that uses libnet, actually it is a book example, and I cannot find a version 1.1 or 1.0 of libnet. I am going to somehow have to track the depreciation of certain functions and I have never done something like this before. …  |
| | So, I recently wrote a program for a class that involved writing an aggregate class to a file. This particular program had an order object, and each order could have 10 ice cream cones, so a ToString() of the class would look like this: Order Number: 1 Customer #1: Harrington, … |
| | How does one roll back a readline from a text file? |
| | Is there any difference between returning a pointer to a struct, and returning a struct? Aside from the derefrenceing that is done would they both be working with the same struct? Is there any copying that gets done if it is just a regular return? |
| | I am relatively new to C#, does anybody have a simple example of how calling C++ from C# would be done? I heard that C# can call other languages.  |
| | So, I wrote some code for appending to an array, and I thought to myself, would be cool to make the method more generic using an interface. I keep getting this error though that basically says that the compiler's best overloaded method that can match this is _____, and it … |
| | I am wondering, when does it become more efficient to pass by value in C#? I was reading this article: http://msdn.microsoft.com/en-us/library/4d43ts61%28v=vs.90%29.aspx The article suggests that passing by reference actually generates overhead when it transferrs the value type to the heap. My C/C++ classes swore by passing by reference as a … |

| | I just glued together two codes I found online, and found an interesting result. Some of my flash drives have been appearing twice on the system. Here is what the output looks like: Drive: C:\ Volume Name: Drive: D:\ Volume Name: Drive: E:\ Volume Name: Drive: F:\ Volume Name: Drive: … |
| | Hello, I was doing some research on enumerating the different drives on a system, and I found some code on MSDN. Here is the page: http://msdn.microsoft.com/en-us/library/windows/desktop/aa364975%28v=vs.85%29.aspx The source code looks like this: DWORD dwSize = MAX_PATH; char szLogicalDrives[MAX_PATH] = {0}; DWORD dwResult = GetLogicalDriveStrings(dwSize,szLogicalDrives); if (dwResult > 0 && dwResult … |
| | Hello, I am working on a program, and I noticed that all my threads are starting and stopping in exactly the same order I put them in, and they are not trading places in the output, or mixing output like concurrent objects should. Here is my code: public class RaceHorseAppII …  |
