• Is there an easy way to get the ServerName in Symfony?

  - by greg0ire

  I have been searching for an easy way to get the ServerName of the machine where Symfony runs in Symfony (so that my app adapts when it is used on a host with a different ServerName), but I couldn't find one. I created a variable in app.yml and I fetch it, but I still wonder if there is no easier way to do this. How are you doing this? I'm using Symfony 1.2 and 1.4 on different projects.

• deep or shallow copying?

  - by Dervin Thunk

  Dear all. I was wondering if there are examples of situations where you would purposefully pass an argument by value (deep copy) in C. For instance, passing a char to a function is usually cheaper in space than passing a char* (if there's no need to share the value), since char is 1 byte and pointers are, well, whatever they are in the architecture (4 in my 32 bit machine). ?(When) do you want to pass (big) deep copies to functions? if so, why?

  <Binary Id="binUpdate" SourceFile="c:\xxx\Update.exe"/> <CustomAction Id="Update" BinaryKey="binUpdate" Execute="deferred" ExeCommand="c:\xxx" /> When I build a Wix project with the above custom action, it complains that "The system cannot find the file 'C:\xxx\Update.exe". This update.exe is deployed by the same msi. So, how do I make Wix to ignore the fact that the file does not exist on my build machine? Thanks in advance

• Auto update your applications through Windows Update

  - by vucetica

  Here is a scenario: User installs .NET application that you have made. After some time, you find a security issue in it and create a patch for it. When patch is ready, you post it "somewhere", and when next Windows update is run on user's machine (automatically or manually), that application is updated, too. I'm wondering if this is possible...and how? Searching on MSDN about it, didn't give any results.

• MSSQL using SSH-tunnel from Visual Studio

  - by pbt

  Hi, I recently contacted a web host regarding support for external database access to a Microsoft SQL Database included in a package they offer. They replied saying that it is only possible with an SSH-tunnel. Is it possible to connect to a MS SQL database in Visual Studio using an SSH-tunnel? It is important for me to be able to access the database from my local machine (for debugging, generating LINQ classes, editing tables, etc). Or, how should I go about working with their database?
