C/C++: How to store data in a file in B tree -


It appears that one way of storing data in a B-tree, efficiency as a file with C File can be done with the sequence of strokes (array), representing one representative of each node. In this way a personal nodes can be linked to that approach which is similar to the formation of linked lists using ARAS. But then the problems that would have to be removed from one node, it is not possible to delete only a few bytes in the middle of a large file.

One way to remove 'may be to keep an empty track' nodes until it reaches a threshold cutoff and then create another file that will discard the empty node but it is tedious.

Is there a better approach than simplicity / efficiency approach to removing or removing B-trees in the file?

TIA, -Vijaya

I did a very quick search and dug it up: C source: - This disk-based B-tree style database - although taking a look at "delete.c" it seemed that if you remove one node, everything will be taken down - if it is the right behavior So it looks like something that can help?

In addition - B-trees are often used in file systems - can not you see some file system codes?

My own inclination is of a file system - if you have a fixed-size B-tree, whenever you "delete" a node instead of attempting to delete the reference, just set the value that There is nothing in your code too. After that, there is a clean up thread running, which checks if a file opens to read and if all becomes silent then block the file and blocks.

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...
