• Visual C# Debug vs. Unit Testing

  I was hoping to get some opinions about using the System.Diagnostics.Debug class instead of or in addition to NUnit unit testing. What do other developers favor more, Unit Testing or Debug Also what are your thoughts on using the Trace class with TraceListeners to implement logging of an application, say versus using a framework like log4Net Thanks. There is no way you can substitute unit testing for simple use of the Debug class (I'm assuming you mean use of Debug.Assert here ). This is useful for checking that you are in the right state within a class, but does not act as a test driver. You need to unit test to try and create the conditions that could cause your assertions to fail. I tend to use Debug.As ...Show All

• SQL Server Add sum column to query

  What's the best way to include an amount sum in a query if I also need the individual amounts For example, I need the following columns: order number order amount total amount I tried using "with cube ", but the total number of columns in the query exceeds the allowable limit of 10. Could it look something like this create table #x( ordernum int not null, amt int not null ) insert #x select 1, 20 union all select 1, 15 union all select 2, 35 union all select 2, 10 union all select 2, 70 go select ordernum, amt, sum(amt) as total from #x group by ordernum, amt with rollup go ordernum amt total ----------- ----------- ----------- 1 15 15 1 20 20 1 NULL 35 2 10 ...Show All

• Visual Studio Express Editions Can i exclude certain files from being scanned for xml document generation?

  My problem is this: When designing a class, i create the .h header file like so: // foo.h ///<summary> /// This is foo ///</summary> class Foo { public: ///<summary> /// Default constructor ///</summary> Foo(); }; Then when i create the .cpp file i copy the comments into that also so i can read what the function does (at a later date) from any of the 2 files like: // foo.cpp ///<summary> /// Default constructor ///</summary> Foo::Foo() { //do something }; Now when the .xml documentation is generated, for each member it lists the summary twice ie: < xml version="1.0" > < doc > < assembly > "F00" </ assembly > < members > < mem ...Show All

• Visual Studio 2008 (Pre-release) C# 3.0? Extension methods.

  Are questions about C# 3.0 on-topic here I was wondering if extension methods would be applicable to interfaces as well as classes Either supplying default implementations for the contract methods and properties, or adding methods outside of the contract. So the following would be possible: public interface IThing { public void SomeMethod(); } public class Foo : IThing { public void SomeMethod() { ... } } public static class Extensions { public static void OtherMethod( this IThing ithing) { // Do stuff } } ... IThing ithing = foo as IThing; ithing.OtherMethod(); Do we know yet whether this will be possible Yes - this will be possible using extension methods in C#3.0. In fact, this is very si ...Show All

  I have both "Source Control" and "Source Control - Team Foundation" toolbars enabled, when I open a .cs file under source control (so it's the active document I'm looking at) the "compare" button stays disabled. How can I enable this button or compare the current document to the latest version at a click of a button First, the Source Control toolbar is for VSS, and the Source Control-Team Foundation toolbar is for TFS. so For TFS, there is no compare button in this toolbar, you can do it through Context Menu in Solution Explorer. ...Show All

• Architecture Factory pattern question

  i am building a data access layer for some reports. this is a smart client application so the report data may be generated from a database or from a locally stored xml file, etc. i dont want my business layer to worry about how the data is retrieved. all my business layer should say is "get me the data! i don't care how! just get me it!". i thought that i could use a factory pattern - something like this: ReportFactory reportFactory = new ReportFactory(); IReport myReport = reportFactory.GetReport(StorageTypes.Database); DataTable dataTable = myReport.GetData(); ok. but in this scenario the database driven class needs some extra settings such as connection string. whereas the xml based report might need to know oth ...Show All
