asp.net - Dynamic Connecton String Based on Session Variable -

-

I have an application that launches data for my client over a period of time, the client is called 'play' wide To allow other scenarios to mess up production data, they can choose an alternative database (basically what-if scenario) at any point, which is a copy of the production database At a certain time currently, I have There is a bit of code which The connection replacement string to string, which will hot-swap server name and the database name on the basis of the stored user session state.

This approach works well for what I'm doing, although I need to cross those selections at every level. My question is: Would I be able to create a custom connection string which handles this 'switching' in the background and allows me to use a string like I do in the standard ASP.Net application.

In other words, many asp.net tools accept only a connection string name as part of its manufacturer. I want to be able to use those tools, but the way I currently create my connection string, I can not do B / C. Is there a way to support this behavior at user session level?

Working with it.

Some people have their own web Complete copies of config files (where connection strings should be kept) and using Post-Build events, they can copy a relevant web.config file based on the "Release Configuration" that you can use in Visual Studio Are there.

This method is also Scott Gu. Besides this, see this stack overlow question:

Now, there are very good ways, initially ASP.NET applications deployed , if You want to do this, when this application is already posted you can use this functioning mechanism:

It looks like you are already doing something like this , And if you want to dynamically switch the database in a timely manner, then I think you can Can also be simply attributed to "switch" the connection string in the Y provide our Code Of course, here's the trick to make it easier so that the database connection string is only one place in your application for the rest of your application. Perhaps the best way to handle it is to make sure that all the values ​​you want to get from web.config are obtained using the class obtained from the class. It is necessary for you to "switch" any argument (such as "connection string-based-on-machine-name" moves) back to a real value, and you can use "connectionstring" of your custom class Will allow to allow "the property in the constructor of any other component is required, for which the connection string needs to be changed as a parameter, when it is connected to the actual connection Writing value changes.

There are some good resources for custom configuration sections:

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
