I, at least, would have a much easier time helping you if I knew what
programming language and/or development platform you were using. The
answers are likely to be very different for eVC with MFC, eVC without
MFC, eVB, C#, and VB.NET.

I'll try to be a generic as possible, but I use only eVC without MFC,
and definitely don't know some critical pieces of info about the
others.

1) Are you trying to run the same executable? If you are using eVC,
then the executables you build for the emulator cannot run on real
devices, and vice versa. The "executables" generated by VS.NET are
actually an intermediate code that gets compiled at run time; I don't
use VS.NET, so I don't know whether a single "executable" can run on
emulator and real devices.

2) If you are trying to run an executable that was built for the
actual hardware, then you need to find a break point near the
beginning of your program. The actual beginning is likely not where
you think. If you are using straight Win32 with C/C++, you can try
putting a break point in WinMain. But if you have variables declared
in WinMain, their constructors will be called before WinMain. And if
you have any file-scope variables, their constructors will be called
even sooner.
