supress c5 error messagebox 2

[AlastairP]

I am looking for way to supress the C5 error messagebox.
I have a non visual utility program that runs briefly, does a small task and then shuts down.
Occasionally, maybe every 1000 or so executions I get a C5 error.
I will keep on looking to try and resolve the error, however I want to supress the error message box. In fact I want to supress any error message box.
Can this be done?

I am using a standard ON ERROR error handler that directs the error to file

MAIN.PRG

PARAMETERS payloadFile, testmode2

&&& MAIN.PRG &&&
ON ERROR DO ErrorHandler WITH ERROR( ), MESSAGE( ), MESSAGE(1), PROGRAM( ), LINENO(1)

MAIN.PRG

********************
PROCEDURE ErrorHandler
********************
   PARAMETER tnError, tcMessage, tcMessage1, tcProgram, tnLineno
   LOCAL lcErrorMessage
   lcErrorMessage = "Date : " + TTOC(DATETIME(),3)  + CHR(13) + CHR(10) ;
   	  +	"Error number: " + TRANSFORM(tnError) + CHR(13) + CHR(10) ;
      + "Error message: " + tcMessage + CHR(13) + CHR(10) ;
      + "Line of code: " + tcMessage1 + CHR(13) + CHR(10);
      + "Program: " + tcProgram + CHR(13) + CHR(10);
      + "Line number: " + TRANSFORM(tnLineno)
   	
   	lcDirectory=_screen.clientpath
   	lcLine = CHR(13)  + CHR(10) + '*************************************************' 
   	lcFinalText = lcLine + CHR(13)+ CHR(10)  + lcErrorMessage + CHR(13)  + CHR(10)
   	
   	
   	
	IF DIRECTORY(_screen.clientpath) 
		SET SAFETY OFF  
		
		IF FILE(_screen.clientpath + 'ERRORLOG.TXT')
	 		lctext = FILETOSTR(_screen.clientpath + 'ERRORLOG.TXT')
	 		IF LEN(lctext > 10000000) 
	 			STRTOFILE(lcFinalText  , _screen.clientpath + 'ERRORLOG.TXT',0)
	 		ELSE 
	 			STRTOFILE(lcFinalText  , _screen.clientpath + 'ERRORLOG.TXT',1)
	 		ENDIF 	
	 	ELSE 
	 		STRTOFILE(lcFinalText  , _screen.clientpath + 'ERRORLOG.TXT',0)
	 	ENDIF 	

	    SET SAFETY ON       
	ENDIF 
		

   SET DEFAULT TO (_screen.clientpath)

   CLEAR EVENTS
   
ENDPROC

With regards

Unfortunately, an ON ERROR handler cannot trap C5 errors. The C5 error happens before the error-handler can kick in.

As far as I know, the only way to prevent the C5 from appearing on the screen is to find the cause of the error and to eliminate it.

Thanks Mike,

The crash dump pointed to NahimicOSD.dll
It is an audio driver I believe.
