The only way I know to calculate the number of bytes of DBCS string in a given encoding is: 1. Translate the string to Unicode (MultiByteToWideChar) 2. Translate the Unicode string to the previous encoding (WideCharToMultiByte) this function return the size of DBCS string in bytes. This work (in all the case that I know of) :) . Good luck.

1. Output debug string does not work from service on 2008 (shared object) 2. Windows probably catch your _asm int 3. 1. Look at the event log. 2. Add log to file.

Did the the service process start at all (You can check it using process monitor)
