• How to unit test private methods in BDD / TDD?

  - by robert_d

  I am trying to program according to Behavior Driven Development, which states that no line of code should be written without writing failing unit test first. My question is, how to use BDD with private methods? How can I unit test private methods? Is there better solution than: - making private methods public first and then making them private when I write public method that uses those private methods; or - in C# making all private methods internal and using InternalsVisibleTo attribute.

• How do I reference sqlite db column to use in update statement

  I am trying to update a datetime column in an android sqlite db to use international date format (yyyy-mm-dd) instead of the current format (mm/dd/yyyy).

• Is arithmetic overflow/underflow generally checked in .Net framework methods?

  - by YWE

  For example, let's use the Add method of the ArrayList class. If I am using the default compiler settings in Visual Studio C# project in which arithmetic overflow is not checked, would ArrayList.Add() throw an OverflowException if I added too many items? Would surrounding the method call with checked or unchecked make any difference? BTW, I would write a test program to determine the answer to this question if I had Visual Studio available to me right now.

• FileStream to save file then immediately unlock in .NET ?

  - by aron

  I have this code that saves a pdf file. FileStream fs = new FileStream(SaveLocation, FileMode.Create); fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length); fs.Flush(); fs.Close(); It works fine. However sometimes it does not release the lock right away and that causes file locking exceptions with functions run after this one run. Is there a ideal way to release the file lock right after the fs.Close()

• Monochrome BitMap Library

  - by Asad Jibran Ahmed

  I am trying to create a piece of software that can be used to create VERY large (10000x10000) sized bitmaps. All I need is something that can work in monochrome, since the required output is a matrix containing details of black and white pixels in the bitmap. The closest thing I can think of is a font editor, but the size is a problem. Is there any library out there that I can use to create the software, or will I have to write the whole thing from the start?

• How can I delete a newline if it is the last character in a file?

  - by Todd Partridge

  I have some files that I'd like to delete the last newline if it is the last character in a file. 'od -c' shows me that the command I run does write the file with a trailing new line: 0013600 n t > \n I've tried a few tricks with sed but the best I could think of isn't doing the trick: sed -e '$s/\(.*\)\n$/\1/' abc Any ideas how to do this?

• Why do updates inside of a SQL transaction still need disk IO?

  - by usr

  In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

• Is there a recommended logging path/folder for ASP.NEt applications?

  - by the-locster

  Currently we use log4net and create a new folder (usually below C:) with write and create access rights for the worker process user. Is there perhaps a standard windows folder we should or could be using such as LOCALAPPDATA? I'm guessing that LOCALAPPDATA is a bad choice in the general case because IIS users tend to be non-interactive users and thus I don't think they have the usual user folder structrues available.
