Updating environment strings Sensual chats

This behaviour is exactly like that of a batch file: the environment variable is replaced by its value when the string is processed.

Some environment variables are actually the result of two variables being merged. Echo "SYSTEM: TEMP=" & wsh System Env( "TEMP" ) Set wsh System Env = Nothing Set wsh Shell = Nothing Set wsh Shell = Create Object( "WScript. Echo Left( "Expanded" & Space( 12 ), 12 ) & wsh Shell.

That can be useful for downstream code running in a website to special case some behavior for connection strings.

Once a developer has entered key-value pairs for their website, the data can be retrieved at runtime by code running inside of a website.

The full list of database connection string types and the prepended string used for naming environment variables is shown below: If you select “Sql Databases”, the prepended string is “SQLAZURECONNSTR_” If you select “SQL Server” the prepended string is “SQLCONNSTR_” If you select “My SQL” the prepended string is “MYSQLCONNSTR_” If you select “Custom” the prepended string is “CUSTOMCONNSTR_” So far we have shown how the key-value pairs entered in the portal flow through to a web application via environment variables. NET web applications, there is some extra runtime magic that is available as well when using the . If the application setting(s) happen to already exist in your web.config file, Windows Azure Web Sites will automatically override them at runtime using the values associated with your website.

NET 4.5 framework (note: this magic is not available if you choose . Connection strings work in a similar fashion, with a small additional requirement.

However, if Windows Azure Web Sites cannot find a connection string with a matching name from the web.config, then the connection string entered in the portal will only be available as an environment variable (as shown earlier).

As an example, assume a web.config entry like the following: A website can reference this connection string in an environment-agnostic fashion with the following code snippet: When this code runs on a developer’s local machine, the value returned will be the one from the web.config file.

The following code, created with the help of Scriptomatic, lists all TEMP variables on the local computer: Set obj WMIService = Get Object( "winmgmts://./root/CIMV2" ) str Query = "SELECT * FROM Win32_Environment WHERE Name='TEMP'" Set col Items = obj WMIService.

Exec Query( str Query, "WQL", 48 ) For Each obj Item In col Items WScript.

NET that dumps out the data using environment variables: Here is what the example page output looks from the previous code snippet: [Note: The interesting parts of the Sql connection string are intentionally blanked out in this post with asterisks.
