If your plugin has been created using the old VB.NET/C# interface, the Iguana communication libraries that your plugin uses are:

• IGC.dll, which implements the Iguana plugin communication protocol;
• IGC_csharp.dll, which provides the interface to IGC.dll that is used by VB.NET and C# plugins.

These files are included with your Iguana installation.

To use these communication libraries, you must:

• Ensure that the directory containing IGC.dll is included in the PATH environment variable on your system;
• If you are using VB.NET or C#, copy IGC_csharp.dll to the directory in which your plugin is located, and add it as a reference in the plugin.

To include IGC.dll in the PATH environment variable:

• From Windows, select Start, Settings, Control Panel and System.

• Select the Advanced tab.

• Click Environment Variables.

• In the System variables panel, locate the PATH environment variable, and click Edit.

• Add the full path of the directory that contains IGC.dll. This should be the directory in which Iguana is installed (for example, C:\Program Files\iNTERFACEWARE\Iguana).

• Click OK.

	Your version of Windows may require a slightly different sequence of commands to access the PATH environment variable. See your Windows documentation for details.

	If you are creating a 64-bit plugin on Windows, you must add the directory in which your 64-bit version of Iguana is installed to your PATH environment variable. In this environment variable, this directory must appear before the directory in which Chameleon is installed. If you are running Iguana on Windows, you have created a 32-bit plugin to interface with 32-bit Iguana and you upgrade to the 64-bit version of Iguana, be sure to save a copy of the 32-bit version of IGC.dll and ensure that your 32-bit plugin refers to it. This will allow you to continue using your 32-bit plugin with 64-bit Iguana. A 32-bit plugin will not work with the 64-bit version of IGC.dll that is included with the 64-bit version of Iguana.

To add a reference to IGC_csharp.dll to your VB.NET or C# plugin:

• Use Windows Explorer to locate the directory in which IGC_csharp.dll is located. This is normally the plugins subdirectory of the directory in which Iguana is installed (for example, C:\Program Files\iNTERFACEWARE\Iguana\plugins).

• Copy IGC_csharp.dll from this directory to the directory in which your plugin is located.

• From the Project menu, select Add Reference.

• Click the Browse tab.

• Use the directory browser to locate the copy of IGC_csharp.dll that you have just created.

• Click OK to add the reference.
