• How do I inhibit "note C6311" in Microsoft C compiler?

  - by piCookie

  In this maximally clipped source example, the manifest constant FOOBAR is being redefined. This is deliberate, and there is extra code in the live case to make use of each definition. The pragma was added to get rid of a warning message, but then a note appeared, and I don't seem to find a way to get rid of the note. I've been able to modify this particular source to #undef between the #define, but I would like to know if there's a way to inhibit the note without requiring #undef, since there are multiple constants being handled the same way. #pragma warning( disable : 4005 ) // 'identifier' : macro redefinition #define FOOBAR FOO #define FOOBAR BAR The compiler banner and output are as follows Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8804 for 80x86 Copyright (C) Microsoft Corp 1984-1998. All rights reserved. message.c message.c(3) : note C6311: message.c(2) : see previous definition of 'FOOBAR'

• Maven "Module" vs "Project" (Eclipse, m2eclipse plugin)

  - by Ricket

  I'm a beginner at Maven and I've played with it from a command line point of view a little, so now I was trying to use it in Eclipse; I installed the m2eclipse plugin to do so. But I'm stumped from the very beginning! Apparently I've missed a bit of terminology somewhere along the line. I can't keep track of all these new Maven terms... What is a Maven Project, and what is a Maven Module? These are my options when creating a new project in the Maven category in Eclipse.

• Is git svn rebase required before git svn dcommit?

  - by allyourcode

  I'm reading about using git as an svn client here: http://learn.github.com/p/git-svn.html That page suggests that you do git svn rebase before git svn dcommit, which makes perfect sense; it's like doing svn update before doing svn commit. Then, I started looking at the documentation for git svn dcommit (I was wondering what the 'd' is about): http://www.kernel.org/pub/software/scm/git/docs/git-svn.html You have to scroll down a bit to see the documentation on dcommit, which says this: Commit each diff from a specified head directly to the SVN repository, and then rebase or reset (depending on whether or not there is a diff between SVN and head). This confuses me, because if you do as the first page says, there will be no changes to pull down from svn once the first part of dcommit finishes. I'm also confused by the part that talks about reset; isn't git reset for removing changes from the staging area? Why would rebase or reset follow (the first part of) a dcommit?

• What tech stack/platform to use for a project?

  - by danny z

  Hey guys, This is a bit of a weird meta-programming question, but I've realized that my new project doesn't need a full MVC framework, and being a rails guy, I'm not sure what to use now. To give you a gist of the necessary functionality; this website will display static pages, but users will be able to log in and 'edit their current plans'. All purchasing and credit card editing is being handled by a recurring payment subscriber, I just need a page to edit their current plan. All of that will be done through (dynamic) XML API calls, so no database is necessary. Should I stick with my typical rails/nginx stack, or is there something I could use that would lighten the load, since I don't need the Rails heft. I'm familiar with python and PHP but would prefer not to go that route. Is Sinatra a good choice here? tl;dr: What's a good way to quickly serve mostly static pages, preferably in Ruby, with some pages requiring dynamic XML rendering?

• How do I join two git repos without a common root, where all modified files are the same?

  - by Evan Carroll

  I have a git-cpan-init of a repo which yielded a different root node from another already established git repo I found on github C:A:S:DBI. I've developed quite a bit on my repo, and I'd like to merge or replay my edits on a fork of the more authoritative repository. Does anyone know how to do this? I think it is safe to assume none of the file-contents of the modified files are different -- the code base hasn't been since Nov 08'. For clarity the git hub repo is the authoritative one. My local repo is the one I want to go up to git hub shown as a real git fork.

• Lua: Why changing value on one variable changes value on an other one too?

  - by user474563

  I think that running this code you will get excactly what I mean. I want to register 5 names to a register(people). I loop 5 times and in each loop I have a variable newPerson which is supposed to save all information about a person and then be added to the people register. In this example only the names of the people are being registered for simplicity. The problem is that in the end all people turn to have the same name: "Petra". I playied a bit with this but can't get a reasonable reason for this behaviour. Help appreciated! local people={} local person={ name="Johan", lastName="Seferidis", class="B" } local names={"Markus", "Eva", "Nikol", "Adam", "Petra"} --people to register for i=1, 5 do --register 5 people local newPerson=person local name=names[i] for field=1, 3 do --for each field(name, lastname, class) if field==1 then newPerson["name"]=name end --register name end people[i]=newPerson end print("First person name: " ..people[1]["name"]) print("Second person name: "..people[2]["name"]) print("Third person name: " ..people[3]["name"])

• jQuery Ajax form submit, to call php login script

  - by Stevie Jenowski

  Thanks for checking out my problem... I'm having trouble submitting a login form via Ajax for a php script to run and return a new set of html items which will be replacing the HTML in #userlinks.... heres what I have so far $("#login_form").submit(function() { return false; }); $('#login_button').click(function(event) { $form = $(this).parent("form"); $.post($form.attr("action"), $form.serialize(), function(data){ $('#userlinks').html(data); }); }); The php script checks for post data of username && password, yet all I'm getting is a page refresh and no changes. Nothing returns unless I turn login_button into a link and change the script a bit... Any help would be appreciated!

• IE7 is making my life miserable! Getting gaps between html table columns (w/ colspan) with css togg

  - by Art Peterson

  Copy/paste this html code snippet and try it out in IE7. When you toggle the hidden columns it leaves a gap between the columns. In Firefox it works fine, the columns touch when minimized. Haven't tried IE8 yet, would be curious to hear how it works there. Any ideas? I've tried a bunch of things in the CSS like table-layout:fixed but no luck. Note: Not looking for a different toggling method because the table I'm really dealing with is 50+ columns wide and 4000+ rows so looping/jquery techniques are too slow. Here's the code - if someone can re-post a working version of it I'll instantly give them the check and be forever in your debt! <DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <script> function toggle() { var tableobj = document.getElementById("mytable"); if (tableobj.className == "") { tableobj.className = "hide1 hide2"; } else { tableobj.className = ""; } } </script> <style> table { border-collapse: collapse; } td, th { border: 1px solid silver; } .hide1 .col1 { display: none; } .hide2 .col2 { display: none; } </style> </head> <body> <input type="button" value="toggle" onclick="toggle();" /> <table id="mytable"> <tr> <th>A</th> <th colspan="2">B</th> <th colspan="2" class="col1">B1</th> <th colspan="2">C</th> <th colspan="2" class="col2">C1</th> </tr> <tr> <td>123</td> <td>456</td> <td>789</td> <td class="col1">123</td> <td class="col1">456</td> <td>789</td> <td>123</td> <td class="col2">456</td> <td class="col2">789</td> </tr> </table> </body> </html>

• Security in API authentication

  - by Carlos

  We are in the process of revamping our server side API, and we need to manage security. Our current model requires that a credentials object (containing user, password, and pin) be included in each method invocation. Our development team, however, has decided that we should have session objects instead (which is fine by me), but the new credentials are just a GUID. This is very different from what I've seen in other APIs in our industry, so I'm a bit concerned about how secure the new model will be. I asked them if they had analyzed both alternatives, and they said they haven't. Does anyone know if there're any clear advantages, disadvantages, risks, etc. of using a set of credentials versus just one element (complex as it may be)? PS: the communication channel would be secure in either case, and it's separate from this particular topic

• ASP.NET MVC - Add XHTML into validation error messages

  - by Neil

  Hi, Just starting with ASP.Net MVC and have hit a bit of a snag regarding validation messages. I've a custom validation attribute assigned to my class validate several properties on my model. When this validation fails, we'd like the error message to contain XHTML mark-up, including a link to help page, (this was done in the original WebForms project as a ASP:Panel). At the moment the XHTML tags such as "< a ", in the ErrorMessage are being rendered to the screen. Is there any way to get the ValidationSummary to render the XHTML markup correctly? Or is there a better way to handle this kind of validation? Thanks

• What's the purpose of the lua "stub" dll for windows.

  - by Roddy

  I'm looking at incorporating Lua into a C++ project, and am a bit confused by the presence of the two binaries (lua51.dll and lua5.1.dll) in the distribution from Luabinaries. According to the docs... In Windows your library or application must be linked with a stub library. A stub library is a library with only the function declarations that will bind your DLL with the Lua DLL. Why? I've never needed stub DLLs before when linking with third-party DLLs?

• What HTTP headers are required to refresh a page on back button.

  - by cantabilesoftware

  I'm trying to get a page to refresh when navigated to from the back button. From what I understand after reading around a bit I should just need to mark the page as uncacheable but I can't get any browsers to refresh the page. These are the headers I've currently got: Cache-Control:no-cache Connection:keep-alive Content-Encoding:gzip Content-Length:1832 Content-Type:text/html; charset=utf-8 Date:Mon, 07 Jun 2010 14:05:39 GMT Expires:-1 Pragma:no-cache Server:Microsoft-IIS/7.5 Vary:Accept-Encoding Via:1.1 smoothwall:800 (squid/2.7.STABLE6) X-AspNet-Version:2.0.50727 X-AspNetMvc-Version:2.0 X-Cache:MISS from smoothwall X-Powered-By:ASP.NET Why would the browser pull this page from it's browser history and not refresh it?

• How do i return a StringWriter When I cant Clone it?

  - by acidzombie24

  My code looks like the below. Obviously i cant write 'ok' because the object has been disposed. I cant do return sw.Clone() bc clone doesnt exist. If i dont use a using then at any point between = new and return (like iterating and writing to the object as my example doesnt do) can have an exception and thus not disposing the object. Am i to define sw outside of a try block and check if its null then dispose in a catch block? That seems like a bit of excessive work. Is there a better way? is that the only way? static void func1() { using (var sw = func2()) { sw.WriteLine("Ok"); } } static StringWriter func2() { using (var sw = new StringWriter()) { return sw; } }

• JSTL Session Lookup - Key Has Periods

  - by John W.

  Hello All, I am working with some legacy code, and at some point there is a key in the session that is something like session.setAttribute("com.org.something.Object",someObject); Now trying to access this in a jsp using jstl is a bit difficult becuase if I tried it like I normally would I would do: ${sessionScope.com.org.something.Object.someFieldGetter} As most of us can imagine it will fail because there is no com object in session scope. I also tried ${sessionScope.'com.org.something.Object'.someFieldGetter} And a parsing error was thrown. Does anyone know how to resolve this so that I can correctly get the object similar to session.getAttribute("com.org.something.Object") but through jstl? thank you.

• need to query MongoDB using php

  - by Mario Villarroel

  I need to query mongodb with something like this: ("something" < X OR "something" = "nll") AND ("someother"X OR "someother"= "nll") AND z=$z AND s=1 I've tried a few things, but can't get it to work, this is what I've tried: find( array( '$or'=array(array("something"=array("$le",$X)),array("something"="nll")), '$or'=array(array("someother"=array("$ge",$X)),array("someother"="nll")) )) But that's getting me the OR overwritten, so I'm lost on that... After diggin a bit more, I assembled this code that seems to be what I need, but doesn't work either: find( array('$and'=array( array( '$or' = array( array("something"=array('$gte'=$X)),array("something"="nll"))), array('$or' = array( array("someother"=array('$lte'=$X)),array("someother"="nll")))),"Z"=$z, "s"="1"); But this doesn't work as it returns zero results and I know for sure that there are more than 2 items that match on the db. (100% certain)

• Python - converting wide-char strings from a binary file to Python unicode strings...

  - by Mikesname

  It's been a long day and I'm a bit stumped. I'm reading a binary file that contains lots of wide-char strings and I want to dump these out as Python unicode strings. (To unpack the non-string data I'm using the struct module, but I don't how to do the same with the strings.) For example, reading the word "Series": myfile = open("test.lei", "rb") myfile.seek(44) data = myfile.read(12) # data is now 'S\x00e\x00r\x00i\x00e\x00s\x00' How can I encode that raw wide-char data as a Python string? Edit: I'm using Python 2.6

• Weird use of generics

  - by Karl Trumstedt

  After a bit of programming one of my classes used generics in a way I never seen before. I would like some opinions of this, if it's bad coding or not. abstract class Base<T> : where T : Base<T> { // omitted methods and properties. virtual void CopyTo(T instance) { /*code*/ } } class Derived : Base<Derived> { override void CopyTo(Derived instance) { base.CopyTo(instance); // copy remaining stuff here } } is this an OK use of generics or not? I'm mostly thinking about the constraint to "itself". I sometimes feel like generics can "explode" to other classes where I use the Base class.

• Is there an easy way of obtaining the total page response time in ASP.Net?

  - by Earlz

  Hello, commonly on say PHP or other web frameworks getting the total response time is easy, just start the timer at the top of the file and stop it at the end. In ASP.Net there is the whole Page Lifecycle bit though so I'm not sure how to do this. I would like for this response time recording to take place in a master page and the response time show up in the footer of pages. What would be the best way of doing this? Is there something built in to ASP.Net for it? Is it even possible to include the OnRender time?

• Getting javascript mouse position relative to website prefferably without jQuery

  - by Constructor

  I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

• Thinking of an Inner Join as a Cross Join and then satisfying some condition(s)?

  - by Jian Lin

  It seems like the safest way to think of an Inner Join is to think of it as a Cross Join and then satisfying some condition(s)? Because the equi-join can be obvious, but the non-equi-join can be a bit confusing. But if we always use the Cross Join, and then filter out the ones satisfying the condition, then we get the resulting table. In other words, we can always analyze it by using the first record on the left table, and then go through every single records on the right, and then repeat that for 2nd record on the left, and for the 3rd, 4th, ... etc. So in our mind, we can analyze it using this way, and it is like O(n^2), although what happens in the DBMS maybe that it is a lot faster (when an index is present). Is there another good way to think of it besides this method?

• What is the ratio of Java programmers to C#.net programmers?

  - by Vaccano

  How many Java Programmers are there to every C# programmer? I have a coworker that says it was 3:1 (3 Java to 1 C#) but it is now more like 2:1 (2 java to 1 C#) Is this valid? Is there somewhere I could go for this info? Edit: This question needs to be a bit more limited in scope. I am referring to US programmers and those who would consider their career to be more focused in one side than the other. (If you are evenly balanced then you would cancel out.)
