Can we throw an exception with the PolyFit command?

[plit string]

Let say the caller sends not identical arrX & arrY size, then the PolyFit will generate an error. With the GetAnalysisErrorString we can know what error is it!

However can we declare some thing as  i_bPrevBreak = SetBreakOnLibraryErrors (FALSE); and  SetBreakOnLibraryErrors (i_bPrevBreak); // restore previous break condition in oder to throw an exception?

Note: The 2 above commands do not work in this case!

Thanks to any help

I found the command:

int oldValue;
oldValue = SetBreakOnProtectionErrors (0);
/* Statement that erroneously reports an error */
SetBreakOnProtectionErrors (oldValue);

[plit string]

Oopps,

I did try over and it does not work when the size of array_X is less than the size of array_Y, sorry about my early successful comment ... it still displays the error (as attachment). SO if someone know better protection please help!

It is very embarassing, the first commands are good. To pay my mistakes here is the codes which working in my case:

 /* Statement that erroneously reports an error */
 i_bPrevBreak = SetBreakOnLibraryErrors (FALSE);
 i_error = PolyFit (db_arrX, db_arrY, i_size, i_degree, db_arrOutput, db_arrRet, &mse);
 SetBreakOnLibraryErrors (i_bPrevBreak);
 
 if(i_error != 0)
 {
  sprintf(str, "Error nuber = %d", i_error);
  MessagePopup ("SCI_LEASTSQUAREFIT ERROR", str);
  return db_arrX;
 }

*) Sometimes, it is just a bad day!
