Well, quite simple. I'm going to execute Make (F7), and then following output is generated:
--------------------Configuration: AINandDIO - Win32 (WCE ARMV4I) Debug--------------------
Compiling resources...
Compiling...
Error spawning clarm.exe
AINandDIO.exe - 1 error(s), 0 warning(s)
When I'm running the compiler platform with administrator privilege (thus within the normal user session), the problem with the debug connection occurs.
e.g. USB / ActiveSync does not work. Perhaps ActiveSync must run in administrator mode, too. But I can't close this app. Closing it will move itself into the task bar...
