It can be hardware/OS dependent so on one machine it may terminate program but on some other other not. There is many different WinCE versions, ARM processors and other devices used in mobile devices. Anyhow Harbour core code should not GPF. If it does then it should be fixed. What problem have you found? BTW if it really GPFs (Genral Protection Fault) and it's not other error then your device has memory protection. In you previous posts you tried to assign 0x00000000 and 0xFFFFFFFF - maybe these addresses belongs to process. In such case try different. And how you detected that they not generate exception? Maybe in your device producer uses some exception handler which simply causes that exceptions are ignored. Quite often practice to hide bugs in pure quality software. Maybe it's possible to change default exception handler to your own which will call hb_errInternal() or simply: exit( EXIT_FAILURE );. In source/vm/extrap.c SetUnhandledExceptionFilter() is disabled for WinCE builds because it was missing in some testing WinCE environments but maybe the one you are using supports it. If yes then please send us information about exact environment so we can enable it for such builds. You can also try to cange the return value in exception filter from EXCEPTION_CONTINUE_SEARCH to EXCEPTION_EXECUTE_HANDLER. Maybe it's possible in your environment to overload default exception handler by adding your own UnhandledExceptionFilter() function to the application code. You can try. Anyhow valid Harbour application should not generate exceptions so all of the above is for some rather abnormal situations. > JLC>If there is no hardware support then you will not make it > JLC>in such way.

An example can help me a lot. check in google: try catch throw and the 1-st link will point to MSDN documentation. best regards, Przemek _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
