    response.write("Error reading file C:\Samples\Tutorial30.csv")
    response.write(workbook.easy_getError())
end if

' Dispose memory
workbook.Dispose

Overloaded methods
For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation.
