// This example shows how to get the range of cells that a user has selected
// on the active worksheet.
// Have a worksheet window active, make a range selection on the worksheet,
// and then call this function
//
void get_worksheet_selection()
{
	// Declare worksheet object with active layer
	Worksheet wks = Project.ActiveLayer();
	if( !wks )
	{
		out_str("Active layer is not a worksheet!");
		return;
	}
	int c1, c2, r1, r2;
	// Get worksheet selection
	int	nSelType = wks.GetSelection(c1, c2, r1, r2);	
	// If nothing was selected, return
	if( WKS_SEL_NONE == nSelType )
	{
		out_str("Nothing was selected in the worksheet!");
		return;
	}
	// Report selection
	printf("Selection: Row %d, Col %d to Row %d, Col %d\n", r1 + 1, c1 + 1, r2 + 1, c2 + 1);
	// Note: 1 was added to r1, c1 etc because Origin C uses 0-based offset and in the
	// GUI typically the count starts at 1.
	
	// One can then perform further processing on the selection
	// such as, for example:
	// Get the selected cells into a matrix object
	matrix mat;
	BOOL bRet = mat.CopyFrom(wks, r1, c1, r2, c2);
	// Report min, max, mean, and median
	printf("Min, max, mean and median of selection: %f, %f, %f, %f\n",
		mat.GetMin(), mat.GetMax(), mat.GetMean(), mat.GetMedian());	
}
