EX1

void check_cols_in_range_with_same_datatype_Ex1()
{

    if( wks )
    {
		DataRange dr;
		dr.Add(wks, 0, "X");
		dr.Add(wks, 1, "Y");
		
		if(check_cols_in_range_with_same_datatype(dr)) // returns true since column default data type is double
		    printf("columns in selected data range have same data type\n");
		else
		    printf("columns in selected data range have NOT same data type\n");
		
		// set two columns to different data type
 		wks.Columns(0).SetFormat(OKCOLTYPE_NUMERIC);   	
  		wks.Columns(1).SetFormat(OKCOLTYPE_NUMERIC);   	
		wks.Columns(0).SetInternalDataType(FSI_LONG); 		
		wks.Columns(1).SetInternalDataType(FSI_DOUBLE);
		
		if(check_cols_in_range_with_same_datatype(dr)) // returns false
		    printf("columns in selected data range have same data type\n");
