c++ - g++ compilation error of another thing that works in msvs -


People, I'm posting some code from a project developed in MSVS to use GSAR. I have found very little difference, most of the things that allow MSVS but do not + G ++ are generally something that involves C ++ standards, things that give MSVS slides, but I There is a problem in seeing what is wrong in a particular section.

G ++ is having trouble matching operator to call! =, But seeing only a specific reference operator! = Works for a specific nested class if the hosting class is not a template, if I change the hosting class in class templates, everything breaks I'm losing something fundamental to either C ++ or G ++ I am doing something wrong.

I have not learned to cry "compiler bug"! Many times, so I want to see if anyone can see here what I am missing.

This work example is working, non-template version, and then broken, template version. G ++ - Gives Vision: G ++ (Ubuntu 4.4.1-4ubuntu9) 4.4.1

Working Reference Versions Without Templates 

  Namespace Works {Structure Host {Straight Iterator} {}; Iterator OP (); }; Bull Operator! = (Host :: Iterator Const & A, Host :: Iterator Const & A1); Bull F () {returns host (). Op ()! = Host () Op (); }} // namespace work

broken version with templates 

  Namespace Broken {template : Iterator Constant & A, Typnam Host  T & gt; :: Iterator b & amp; a1;); Bool f () {Return Host & lt; Int & gt; (). Op ()! = Host & lt; Int & gt; (). Op (); }} Name Location Broken

The template version fails with errors: 

  main.cpp: 'bool broken :: f in the function ) ': Main.cpp: 50: Error:' Broken :: Host & lt; Int & gt; Operator! = ':: Host & lt; int & gt; () Broken :: Host & gt; T & gt; with Broken :: Host & lt; T & gt; :: op [T = int] ; :: op [with t = int] () '

This MSWC and GCC Neither works in.

The problem is that host : iterator , T in non-titular reference Since neither the parameter can be estimated to T , the function template can not be institute.

This is the reason that you usually have cell Define overloaded operators. 

  The Straight Eratorator {Dude Bull Operator! = (Iterator Const & LHS, Iterator Const & RA) {Return False;}};

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
