Retrieve current mixer levels with WMI?
Is there a way to get Windows audio mixer levels using WMI? For example, to get the current line input level.

Hi, We have an application we're trying to deploy on both 64 bit and 32 bit platforms. Is there a way to put both compiled versions of the code in the same binary, a la Apple and NeXT's fat binaries?

Web development text/code editors for Windows
I'm currently using E-TextEditor. This application is trying very hard to be TextMate for Windows, but unfortunately it isn't very stable. Also, it has some serious problems opening minified files (e.g. 70 kB JavaScript files), which is unacceptable IMHO. Notepad2 has no problem at all opening these files, and seems to be very stable as...

How to spawn Linux process from Windows application?
My interactive 32-bit Windows app (now moving from Delphi [Ent] 2007 to 2009) uses command-line interactions to spawn child processes that do computationally-intensive tasks, which in turn write text files that the GUI parent app parses and analyzes - resulting in an interactive graphical display of the results. I have access to a multi...
How can I calculate the complete buffer size for GetModuleFileName?
The GetModuleFileName() takes a buffer and size of buffer as input; however its return value can only tell us how many characters is has copied, and if the size is not enough (ERROR_INSUFFICIENT_BUFFER).

Impact of SSO on session time out
I need to implement SSO between a windows domain and a J2EE web appliction. I've been thinking what the impact of this would be on the web application's session timeout. We have a 2 hour time out.

IE WebBrowser control: Prevent URLs going into the IE address bar URL history
