I need to profile a real time C++ app on Windows. Most of the available profilers are either terribly expensive, total overkill, or both. I don't need any .NET stuff. Since it is a real time app, I need the profiler to be as fast as possible. It would be excellent if it integrated in some way with Visual Studio 2005/2008, but that's not ...

Hi, We plan to sell a Windows portable application. By 'portable' I mean that it can be run from any Windows computer without installing it.

On Windows/.NET can you think of a way of somehow launching an existing application in the background so the user can not see it but I can interact with it with regular API calls (clicking buttons and such)? This would come in really useful for "wrapping" old applications that I cannot modify. ...
Here is a copy of the datasheet from a microcontroller: Break characters are a full character time of logic 0 (including a 0 where the stop bit would be normally). This is what I want to generate with the windows COM port (Windows SDK). The problem is I don't see a way to have the stop-bit set to zero. Any ideas?` SetCommBreak...
