build - How to locate a compiler in a path with a version number in it? -


I am trying to design a scanstate file for an embedded system project. On my machine, the compiler is on "C: \ Program Files \ IAR Systems \ Embedded Workbench 5.4 \ arm \ bin", I have to create a build system to try toolback, even if another version of Embedded Workbench is installed , Or if the user has chosen to install it somewhere else.

I would also be interested in the strategy used in makefile or ant files as they are also useful here.

What are some strategies to do this? Do I have other options than searching the Windows Registry or "C: \ Program Files \ IAR System \ Embedded Workbench * * Hand \ Bin"?

The easiest solution is to use an environment variable you still have to manually It has to be set, but build system is only required for environment variables, so it can be normal for all build hosts.

For example, your case may be:

EWBARM_V0504 = "C: \ Program Files \ IAR System \ Embedded Workbench 5.4 \ Hand \ Bin"

And other versions, and then you will use% EWBARM_V0504% in place of the path you would use in your build system if the variable is not present, the build will fail, which will use the wrong compiler Better, and easily fixed.

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...
