I have seen references to this function in the FiveWin forum. But I get an unresolved external with FWPPC.
Am I missing something or is this function not available.
Is there a simple way to get the MAC Address, or will I have to attempt to write a wrapper for SendARP in C. My C skills are limited unfortunately.
Cheers
Chris Millard

p:\vce\include\arm\mprapi.h(120) : warning C4068: unknown pragma
p:\vce\include\arm\mprapi.h(1746) : warning C4068: unknown pragma
CEFUNC.prg(1100) : error C2664: 'wsprintfW' : cannot convert parameter 1 from 'void ' to 'unsigned short '
Conversion from 'void*' to pointer to non-'void' requires an explicit cast
NMAKE : fatal error U1077: 'p:\vce\bin\clarm' : return code '0x2'
Line 1100 is the pAdapterInfo->Address[ 4 ] line of wsprintf although I have had problems before with line numbers not matching the problem in embedded C.
I have tried // the two lines in mprapi.h this removed the warnings but still get the fatal error.
Chris,
Please replace this and try it again, thanks:
wsprintf( ( void * ) wText
with
wsprintf( ( WCHAR * ) wText
#include <hbapiitm.h>
extern "C"
char * WideToAnsi( WCHAR * cWide );Chris,
> It now works perfectly, thank you again.
Is it properly showing the MAC address ?
Thanks for your feedback 
Yes the function correctly returns a two element array with the MAC address of the Ethernet adapter and of the Bluetooth adapter.
My device is a TouchStar Technologies, TouchPC Falcon runing Win CE 5.0

Thanks MAurizio
Maurizio,
Here it is from VC98 include folder:

It should be:
