Tutorial 26: How to create pivot charts in C++

How to create pivot charts in C++

EasyXLS Excel library can be used to export Excel files in C++. The integration varies depending on the project technique, if .NET Framework can be used or not.

1. EasyXLS using COM+ for projects without .NET Framework

2. EasyXLS in C++.NET projects using .NET Framework

C++ and .NET Framework
This tutorial is valid for C++ applications that cannot use .NET Framework. It is recommended, for better performances, that if the C++ application already uses or can use .NET Framework to make use of this similar code sample.

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.

EasyXLS in C++.NET projects using .NET Framework

If you opt for the .NET Framework version of EasyXLS, you need a C++.NET project and to include EasyXLS.dll into project.

Find more about Getting Started with EasyXLS

Step 1: Download EasyXLS Excel Library for .NET

To download the trial version of EasyXLS Excel Library, press the below button:

If you already own a license key, you may login and download EasyXLS from your account.

Install the downloaded EasyXLS installer for v8.6 or earlier.

Step 2: License file setup

Step 3: Include EasyXLS library into project

EasyXLS.dll must be added to your project. EasyXLS.dll can be found:
- Inside the downloaded archive at Step 1 for EasyXLS v9.0 or later
- Under installation path for EasyXLS v8.6 or earlier, in "Dot NET version" folder.
