• Typedef in C# across several source files

  - by Danvil

  I am writing a C wrapper an would like to use a typedef aquivalent to define some types which should be valid in quite a lot of source files. Those "types" are just different aliases to [u]int16/32/64_t, but are useful to distinguish function parameters. One could use using MyId=System.Int32;, but this needs to be redeclared in every file as far as I see... Is there a better way?

• jQuery validation plugin: accept only alphabetical characters?

  - by KeyStroke

  I'd like to use jQuery's validation plugin to validate a field that only accepts alphabetical characters, but there doesn't seem to be a defined rule for it. I've searched google but I've found nothing useful. Any ideas? Appreciate your help.

• AbsoluteTime with an integer argument behaves strangely.

  - by dreeves

  This is strange: DateList@AbsoluteTime[596523] returns {2078, 7, 2, 2, 42, 9.7849} But DateList@AbsoluteTime[596524] returns {1942, 5, 26, 20, 28, 39.5596} The question: What's going on? Note that AbsoluteTime with an integer argument is undocumented. (I think I now know what it's doing but figured this is useful to have as a StackOverflow question for future reference; and I'm curious if there's some reason for that magic 596523 number.)

• Is there any simple way to determine when the popup menu was dismissed?

  - by Alex Jenter

  I'm displaying a popup menu using TrackPopupMenu and would like to know when it is dismissed via clicking outside of it. I've looked through all the menu functions but didn't find anything useful in this regard. Spy++ told me that no window message is sent in this case. So, is there an easy way to do it without installing a mouse hook? Thanks!

• Has anyone tried vss2git?

  - by Radicalise

  OK, so I have started a contract where they are using (gulp) Visual SourceSafe and are looking to move to something better. I have recommended Git. I stumbled across vss2git, which looks useful for migrating from VSS. Has anyone used it? Many thanks!

• PHP debugging or performance Hook

  - by Joshua

  In an interpreted language like PHP it is possible in theory to set up some sort of callback function that would be run indiscriminately after every line of code. I am wondering if such a thing exists in PHP or if such a thing could be accomplished in any way? Such a feature could be useful for diagnostics or performance tests. Does anyone know of such a mechanism in PHP?

• What is the most robust way of determining the current codepage from a shell script?

  - by rewbs

  Hi all, I'd like to determine the environment's current codepage at runtime from a Unix shell script. What's the most reliable way of doing this? I'm looking into parsing environment variable $LC_ALL, but it isn't always set to a useful value, and its format seems to vary (can be <locale, or <locale.<code page, or <locale.<code page@<modifier etc...). Is there a better way? I'm essentially after a shell equivalent of what I'd get if I called nl_langinfo(CODESET) from C.

• Any way to reserve but not commit memory in linux?

  - by Eloff

  Windows has VirtualAlloc, which allows you to reserve a contiguous region of address space, but not actually use any physical memory. Later when you want to use it (or part of it) you call VirtualAlloc again to commit the region of previously reserved pages. This is actually really useful, but I want to eventually port my application to linux - so I don't want to use it if I can't port it later. Does linux have a way to do this?

• Does the for foreach construct in java create a hard or soft copy?

  - by Doug

  Say I have the following piece of java code ArrayList<Double> myList = new Double[100]; for (Double x : myList) x = randomDouble(); Does this actually modify myList or just the dummy variable? I realize I should just try this code segment out, but I think this is the sort of thing I should be able to google or search for on this site, and several queries so far have turned up nothing useful.

• Print layout of C++ object with g++ compiler

  - by zaheer

  Is there a way to print the layout of a C++ object using the g++ compiler or any other means. A simplified example (assuming int takes 4 bytes) class A{ int a; }; class B:public A{ int b; } so the output would be A - 0 4 + a + B- 0 4 8 + A.a + b + It would be useful to understand the layout of objects (in my case virtual machine code). Thanks in advance. Regards, Zaheer

• Asynchronous PHP calls?

  - by UltimateBrent

  Is there a way to PHP make asynchronous http calls? I don't care about the response, I just want to do something like file_get_contents(), but not wait on the request to finish before executing the rest of my code. This would be super useful for setting off "events" of a sort in my application, or triggering long processes. Any ideas?

  I would like to download documentation of the Drupal hooks, and whatever else would be useful. I've been saving a few pages piecemeal to my hard drive, but it would take too long to download the entire api.drupal.org this way. Is there someplace where I can get it all at once?

• Tracking user changes in ASP.NET MVC

  - by Ian Roke

  I have a requirement to track what authenticated users change with regards to the data when logged in. I don't need to track what pages they look at although that could be very useful in future. I have thought about saving the User Guid but that seems very clunky. Are there other methods/best practises?
