I am trying to streamline a complex process of storing information in multiple tables and them linking them to a central table. The linking occurs using IDENTITY values generated in each table to provide the unique linking. I know I can use a combination of SET NOCOUNT ON and SELECT @@identity to get each identity, but that still requi...
Is there any good reason that an empty set of brackets isn't valid for calling the default ctor in c++? MyObject object; // ok - default ctor MyObject object(blah); // ok MyObject object(); // error I seem to type "()" automatically everytime. I just wondered if there was a good reason this isn't allowed? ...
Hello all, I am trying to figure out the proper procedure for applying a new tsk based theme file in windows mobile 6.1. I have tried working off of the page http://www.pocketpcdn.com/articles/changetodaytheme.html But this only changes the background, not the system colors for things such as the top and bottom bars on the screen. wce...
I've been programming in C++ for a few years, and I've used STL quite a bit and have created my own template classes a few times to see how it's done. Now I'm trying to integrate templates deeper into my OO design, and a nagging thought keeps coming back to me: They're just a macros, really... You could implement (rather UGLY) auto_ptrs...
I need to solve a few mathematical equations in my application. Here's a typical example of such an equation: a + b * c - d / e = a Additional rules: b % 10 = 0 b >= 0 b <= 100 Each number must be integer ... I would like to get the possible solution sets for a, b, c, d and e. Are there any libraries out there, either open source...
I'm a pretty experienced Java programmer that's been doing quite a bit of Win32 stuff in the last couple of years. Mainly I've been using VB6, but I really need to move to something better. I've spent a month or so playing with Delphi 2009. I like the VCL GUI stuff, Delphi seems more suited to Windows API calls than VB6, I really like...
I've recently decided that I just have to finally learn C/C++, and there is one thing I do not really understand about pointers or more precisely, their definition. How about these examples: int* test; int *test; int * test; int* test,test2; int *test,test2; int * test,test2; Now, to my understanding, the first 3 cases are all doin...
I have roughly the following code. Could this be made nicer or more efficient? Perhaps using std::remove_if? Can you remove items from the map while traversing it? Can we avoid using the temporary map? typedef std::map<Action, What> Actions; static Actions _actions; bool expired(const Actions::value_type &action) { return <something>...
I have to integrate a large Java library in a quite large C++ application. A solution is to use JNI but this requires to hand code all the classes. Python has, for example, a wonderful solution with JPype (http://jpype.sourceforge.net/) that automatizes the process (although the same solution cannot be applied to C++ due to C++ and Pytho...
My style of coding includes the following idiom: class Derived : public Base { public : typedef Base super; // note that it could be hidden in protected/private section, instead // Etc. } ; This enables me to use "super" as an alias to Base, for example, in constructors: Derived(int i, int j) : super(i), J(j) { } ...
What is the best encryption library in C/C++ In terms of: entropy quality ease of use readability portability performance What's your favorite and why do you like it? ...
Anyone have a freely available base64 decoding code snippet in c++? ...
I am looking for a method to compare and sort UTF-8 strings in C++ in a case-insensitive manner to use it in a custom collation function in SQLite. The method should ideally be locale-independent. However I won't be holding my breath, as far as I know, collation is very language-dependent, so anything that works on languages other than...
With very large amounts of ram these days I was wondering, it is possible to allocate a single chunk of memory that is larger than 4GB? Or would I need to allocate a bunch of smaller chunks and handle switching between them? Why??? I'm working on processing some openstreetmap xml data and these files are huge. I'm currently streaming th...
For my current C++ project I need to detect a unique string for every monitor that is connected and active on a large number of computers. Research has pointed to 2 options Use WMI and query the Win32_DesktopMonitor for all active monitors. Use the PNPDeviceID for unique identification of monitors. Use the EnumDisplayDevices API, and...
Is there anyway to build a solution to target 64 bit environment in vs2003? My solution is native c++ not visual c++. Any help would be greatly appreciated. cheers, RWendi ...
Before I begin, I want to clarify that this is not a command-line tool, but an application that accepts commands through it's own command-line interface. Edit: I must apologize about my explanation from before, apparently I didn't do a very good job at explaining it. One more time... I am building a command-line interface application t...
I'm working on a commercial (not open source) C++ project that runs on a linux-based system. I need to do some regex within the C++ code. (I know: I now have 2 problems.) QUESTION: What libraries do people who regularly do regex from C/C++ recommend I look into? A quick search has brought the following to my attention: 1) Boost.R...
We have a project with many dll files which get loaded when the application starts. The baseaddresses of the dll files do overlap so that the memory image gets relocated. Is there a possibility to assign the baseaddresses automatically or a way to calculate a "good" baseaddress for each dll file? ...
I'm wondering if anyone can recommend a good C++ tree implementation, hopefully one that is stl compatible if at all possible. For the record, I've written tree algorithms many times before, and I know it can be fun, but I want to be pragmatic and lazy if at all possible. So an actual link to a working solution is the goal here. Note:...
