  I need to retrieve my data from a ListView control set up in Details mode with 5 columns.

• c++ Function pointer inlining

  - by wb

  I know I can pass a function pointer as a template parameter and get a call to it inlined but I wondered if any compilers these days can inline an 'obvious' inline-able function like: inline static void Print() { std::cout << "Hello\n"; } .... void (*func)() = Print; func(); Under Visual Studio 2008 its clever enough to get it down to a direct call instruction so it seems a shame it can't take it a step further?

• Crunchbang asks for URIs to get build dependencies for php5 [closed]

  - by Koen027

  I'm trying to install PHP5, by compiling it myself. I'm doing this on Crunchbang Linux, version 11. Specifically, the version using the 3.2 kernel. Crunchbang 11 is based on Debian. This is a 64-bit Virtual machine, running on a 64-bit Win7 Professional. Using Virtualbox 4.2 This is my sources.list file: http://pastebin.com/rQJNwX7c When I try to do sudo apt-get build-dep php5, I get the following output: Reading package lists... Done Building dependency tree Reading state information... Done E: You must put some 'source' URIs in your sources.list I'm not sure what's going on here. Can anyone point out what's missing in my setup? Also, since I'm under 300 reputation on serverfault, I can't add the "crunchbang" tag.

• How to know ".automaticDestinations-ms" files to which app relates?

  - by Timotei Dolean

  Hello! Does anyone know (Because on microsoft forums nobody answered me), how can I find what app has which automaticDestinations-ms file in %appdata%\microsoft\windows\recent\automaticdestinations ? That's the folder where Windows 7 stores its jump lists, and I want to know how to automatically/programmatic find the relation between each file and an application. At least, even manual I didn't found any pattern, just to look after file extensions in the files, because some programs open files with the same extension (like images), so this method it's not OK for all programs. Do you have any other idea? Maybe knowing the format of those files? Thanks.

• What is your list of programs to install to Windows after a fresh install?

  - by marked

  I am looking for others' list of program that absolutely must be installed to a fresh install of Windows before going any further. I hope to compile a list here to use as reference for all new Windows installs/restores. Automating this list of programs installation is the next step. Some great lists so far! I will continue to monitor this and then make a list of everything I use. Another thought, has anyone come up with a way to automate this? Possibly going to each programs download page, downloading the most recent version, and installing? I may way on this as well, any ideas would be appreciated! As far as the type of machine, most of mine are hybrids i.e- server, workstation, development machine. So all of the above!

• Can Visual Studio manage function prototypes for me in C++ header files?

  - by Gibybo

  In C++, the common practice is to declare functions in header files and define them in cpp files. This leads to always having two copies of every function's prototype. Then whenever I want to change a function's name/return value/parameter, I have to manually change it in both files. This seems unnecessarily tedious and there must be lots of people that share my pain, so is there a way to automate these changes between files in VS? Bonus points for vim solutions as well.

  - by John

Isn't this how piping works? Is what I want possible and if so how?

• MySQL - Limit a left join to the first date-time that occurs?

  - by John M

  Simplified table structure (the tables can't be merged at this time): TableA: dts_received (datetime) dts_completed (datetime) task_a (varchar) TableB: dts_started (datetime) task_b (varchar) What I would like to do is determine how long a task took to complete. The join parameter would be something like ON task_a = task_b AND dts_completed < dts_started The issue is that there may be multiple date-times that occur after the dts_completed. How do I create a join that only returns the first tableB-datetime that occurs after the tableA-datetime?

• How do I use the Google Maps API GPS sensor?

  - by renegadeofunk

  All I've been able to find is how to specify the sensor parameter: http://code.google.com/apis/maps/documentation/v3/#SpecifyingSensor But nowhere does it say how to actually USE it. Isn't the whole point to be able to get the user's current lat/long coordinates through the device GPS, or am I mistaken?

• Passing Activity Context to constructors to use internally - is this bad

  - by jax

  Is is bad practice to pass the Context to a constructor and save it as a private variable for internal use? The other option is to pass the Context as a parameter to methods that need it. Which is the better option? I have a feeling that passing to the constructor might result in memory leaks accidentally.

• Does downloading the same torrent from more than one server increase the sources / seeds?

  - by Petruza

  Does downloading the same torrent from more than one server increase the sources / seeds? edit: What I meant with servers is those like mininova, isohunt and the like. Now I know those aren't the trackers, what I want to know is if when more than one of those indexing sites are linked for the same torrent, if they likely contain different lists of trackers, so getting the torrent from both sites will increase the trackers, hence the seeds, or if it's just in case one of the sites goes down. I guess I can test this getting one torrent from one site with a torrent client and the same torrent, from another site with another client and comparing the list of trackers and the amount of seeders and leechers.

• java random percentages

  - by erw

  I need to generate n percentages (integers between 0 and 100) such that the sum of all n numbers adds up to 100. If I just do nextInt() n times, each time ensuring that the parameter is 100 minus the previously accumulated sum, then my percentages are biased (i.e. the first generated number will usually be largest etc.). How do I do this in an unbiased way?
