• .NET Development Is it possible to write to the desktop space from a .NET application?

  I would like to be able to write directly to the XP/2003 desktop to provide various information, such as disk space, calendar, network information. I have tried using a dynamic web page and scripting, but I always get prompted to allow access of the ActiveX control to the local system (which is fair enough but a problem here). I have tried to look through the .net framework, but cannot see a way to write to the desktop area.  The information would need to be set during login or dynamically there after.  It is not a problem having an app that is running either from startup or as a service. Anything that is written to the desktop sho ...Show All

• Visual Studio Team System Checkout on large tree takes a long time

  If I do a checkout (shared changes) on a large tree ($/Main), it takes a very long time.  I'm using the B3 refresh.  The Preparing to checkout stage takes several minutes.  The underneath Main, there are over 100 projects with a total of a few thousand files.  This needs to be made much faster; checking out a large tree shouldn't take 5-10 min as this is a common operation.  Anyone else see this; has this issue been addressed in later builds Thanks, --Oren We have addressed at least a significant portion of the issue.  A portion of the code that produces the "joe has a pe ...Show All

• SQL Server Database Sort Order / Collation

  I have an O2 Xda IIs Pocket PC running PPC 2003 SE, WWE (Worldwide English) edition. I want to create a database which contains all Chinese characters that have been mapped under the Unicode Standard. I already have a similar database on my desktop PC.
