• What is the difference between these usages: new SubElement() and SubElement()?

  - by pocoa

  Into a class constructor, I need to create some objects on the fly and add them to a vector. Here is my code: ContainerClass::ContainerClass() { for (int i = 0; i < limit; i++) elements.push_back(SubElement()); } Is this the same thing with new SubElement()? Do I still need to free those SubElement() objects into the ContainerClass destructor?

• Changing the Order in a .NET Generic Dictionary

  - by pm_2

  I have a class that inherits from a generic dictionary as follows: Class myClass : System.Collections.Generic.Dictionary<int, Object> I have added a list of values to this in a particular order, but I now wish to change that order. Is there any way (without removing and re-adding) that I could effectively re-index the values; so change the object at index 1 to now be at index 10 for example? For example, this doesn't work: myClass[1].Index = 10;

• Scrollbar moves back after WM_VSCROLL

  - by user146780

  I have a window with its own H and V scrolling. I'm handling the event like this: case WM_VSCROLL: SetScrollPos(hWnd, SB_VERT, (int)HIWORD(wParam), TRUE); break; all I want is for the position of the scroll bar to stay once I release my mouse but what it's doing is just going back to the top after. What am I doing wrong? Thanks

• Why is there no Sum() extension for IEnumerable<uint>

  - by dss539

  It seems that Sum not defined for IEnumerable<uint> (and other unsigned integers, for that matter) var s = new int[] { 1, 2, 3 }; s.Sum(); //works fine var us = new uint[] { 1, 2, 3 }; us.Sum(); //missing method I would like to know: Have I done something fundamentally wrong/misunderstood the situation? What design decisions might cause the omission of IEnumerable<uint>.Sum()? MSDN: Enumerable.Sum

• operator[][] C++

  - by bobobobo

  I'd like to overload operator[][] to give internal access to a 2D array of char in C++. Right now I'm only overloading operator[], which goes something like class Object { char ** charMap ; char* operator[]( int row ) { return charMap[row] ; } } ; It works ok.. Is it possible to override operator[][] though?

• Is objective C 2.0 a proper superset of C?

  - by RankWeis

  I've heard that objective-C is a proper superset of C, but is objective-C 2.0? The reason I ask is that either it isn't, or I misunderstand the phrase 'proper superset', because this code is valid C syntax: import int main () { char *nil = "hello"; printf("%s\n",nil); } But does not compile in Objective-C 2.0. Obviously, this is an easily fixable problem, but I'm writing a paper, and feel that this is something that should be pointed out.

• DirectorySearch.PageSize = 2 doesn't work

  - by Bero

  using (DirectorySearcher srch = new DirectorySearcher(String.Format("(memberOf= {0})",p_Target.DistinguishedName))) { srch.PageSize = 2; SearchResultCollection results = results = srch.FindAll(); int count = results.Count; } count = 3 (THREE) and not 2. Why is that? I don't want to have all results in just one page. I know that PageSize = 2 is silly small but I set that value in this case just for testing purpose (in reality it will be more).

  In one of my header (C++) files I changed #define TIMEOUT 10 to the more(?) C++ way: const int TIMEOUT = 10; It seems however, g++(v 4.4.3) now includes this symbol several times in the binary. $ nm -C build/ipd/ipd |head 08050420 T ToUnixTime 08050470 T ParseTime 080504c0 T ParseISOTime 080518e4 r TIMEOUT 080518ec r TIMEOUT 080518f4 r TIMEOUT 080518fc r TIMEOUT 080503e0 T HandleMessage How come ?
