• .NET Development DateTime.Parse() failing on one machine

  On one of the machines we tested, all calls to DateTime.Parse() throw an IndexOutOfRangeException, generated somewhere in mscorlib.dll.

All machines were set to the "English (United Kingdom)" culture. The failing machine mysteriously has no AM and PM desig ...Show All

• Visual C# StreamReader and File Position

  I'm processing large binary files. These are PCL files, and I'm looking for page boundaries. I want to store the position of each Form Feed, which in PCL is decimal 12, hex 0C. However, that byte can also exist as part of a raster or other binary structure. So I loop through the file, and when I find a "12", I read ahead 14 bytes to compare them to a known string. If I get a match, I know the 12 was a real Form Feed, and I store it's position in ...Show All

• Visual Studio 2008 (Pre-release) Why Close a proxy?

  Hi I know that as a best practice we should call ICommunicationObject.Close after using a client channel.
