what is in fact you need to know that the software engineering field, this structure corresponds to the view UIView and UIViewController this controller side architectures.

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...

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...

sockets - TCP programming with .NET -

I am having a problem with socket programming job I have written a TCP customer who sends commands through sockets / networkstream is. I am using to see the raw data that goes through the stars. Every time I send a "command" (i.e. flush (network stream)), the wirhark application tells me that the checksum in the TCP header is incorrect ("It should be 0x2440 but should be 0x0000.) I get ACK back I do not understand why I will have to take care of the TCP header at the application level. This can not be true. Can anyone know why I am getting this "error"? I do not know about which I am using Net 2.0 sockets with TCP. Thanks. Are you looking at Warhorck, which is sending the data, it can be dump from the machine? If so, then it is possible that checksum is not taken in the stack at the point where the wireershark is watching it. Many network cards these days are TCP checksum offloads, where checksome hardware Security is, and therefore checksum field will...
