  We've got the following repository method public IList<Foo> GetItems(int fooId, int pageIndex, int pageSize , string sortField, string sortDir, out int totalItems) { // Some code } My question is: is it ok to use out in this way.

• Run multiple copies of an app from Visual Studio

  - by HeavyWave

  How can I run multiple copies of the same app in Debug with Visual Studio? For instance, how do I run app.exe /option1 and app.exe /option2 and still debug both? I know I can run them manually and then attach, but I want an automated solution. I have tried writing a small console app just to run 2 processes, but obviously they are not being run under debugger. Any ideas?

• C# - Does foreach() iterate by reference?

  - by sharkin

  Consider this: List<MyClass> obj_list = get_the_list(); foreach( MyClass obj in obj_list ) { obj.property = 42; } Is 'obj' a reference to the corresponding object within the list so that when I change the property the change will persist in the object instance once constructed somewhere?

• Asp.net mvc class reference in session

  - by Billy

  Hi, if I put a custom class in session, then in an action method I get an instance of that class from session, and populate some fields, I noticed that when a different controller gets that class from session, those fields are populated. Even though after the first call didn't save the updated class back in session. is this typical behavior for session objects? I thought I had to use keyword 'static' on the class in session for this to happen thanks

• Overinclusion of libraries C++

  - by wyatt

  I'm reading about how to put a makefile together, but no-one seems to mention what to do if your files require different sets of libraries, they all seem to use the same set of libraries for each file. Since it seems unlikely that every single file has the same libraries, I take it the list they use must amalgamate all of the libraries required across the project. I just wanted to know if there's any downside to including too many libraries, or if the compiler works out which ones are needed and ignores the rest? Thanks

• How to convert rows of a database query to a XML file?

  - by EASI

  I am developing a Delphi application that needs to pick up the rows from a period of work and convert them to a single XML file in order to upload to a 3rd party web-service. Is there any component or library available to do that? If not, what is the best approach of code to build that DB2XML conversor? I noticed that most XML questions are about how to convert it to another type of data. Note: the database will be MySQL or Firebird.

• How to call a prototyped function from within the prototyped "class"?

  - by Jorge

  function FakeClass(){}; FakeClass.prototype.someMethod = function(){}; FakeClass.prototype.otherMethod = function(){ //need to call someMethod() here. } I need to call someMethod from otherMethod, but apparently it doesn't work. If i build it as a single function (not prototyped), i can call it, but calling a prototyped does not work. How can i do it as if i was treating the function just like a class method?

• Replace Entity Framework object

  - by majkinetor

  In MVC app, I am having this big object that is used in classic view/edit/create pattern. When user edits the object I save it as: public bool SetMyObject(MyObject newObject) { MyObject current = GetObjectById(newObject.Id); current.Prop1 = newObject.Prop1 ... current.PropN = newObject.PropN db.SaveChanges(); } MyObject is pretty big so I am wondering is there any better way to do this, not involving per-property assignments. For instance something along the lines db.MyObject.UpdateObject(current, tnew). Ty.

• What is the best way to include other scripts?

  - by Aaron H.

  The way you would normally include a script in bash is source. For example: main #!/bin/bash source incl.bash echo "The main script" incl.bash echo "The included script" The output of executing ./main: The included script The main script Now, if you attempt to execute that shell script from another location, it can't find the include unless it's in your PATH. What's a good way to ensure that your script can find the included script, especially if for instance, the script needs to be portable?
