Calling a C function from JavaScript

After you understand how C-level extensibility works in Dreamweaver and its dependency on

certain data types and functions, it’s useful to know how to build a library and call a function.

The following example requires the following five files, located in the Dreamweaver

application folder Samples/Extending as archives for both the Macintosh and Windows:

■ The mm_jsapi.h header file includes definitions for the data types and functions that are

described in “C-level extensibility and the JavaScript interpreter” on page 459.

■ The mm_jsapi_environment.h file defines the MM_Environment.h structure.

■ The MMInfo.h file provides access to the Design Notes API.

■ The Sample.c example file defines the computeSum() function.

■ The Sample.mak makefile lets you build the Sample.c source file into a DLL with

Microsoft Visual C++; Sample.mcp is the equivalent file for building a Mach-O bundle

with Metrowerks CodeWarrior and Sample.xcode is the equivalent file for Apple Xcode. If

you use another tool, you can create the makefile.

To build the DLL in Windows using VS.Net 2003:

1. Use File > Open > Sample.mak with Files of type set to All Files (*.*). (VS.Net 2003 does

not open .mak files directly). You are then prompted to verify that you want to convert the

project to the new format.

2. Select Build > Rebuild Solution.

When the build operation finishes, the Sample.dll file appears in the folder that contains

Sample.mak (or one of its subfolders).

To build the DLL in Windows using Microsoft Visual C++:

1. In Microsoft Visual C++, select File > Open Workspace, and select Sample.mak.

2. Select Build > Rebuild All.

When the build operation finishes, the Sample.dll file appears in the folder that contains

Sample.mak (or one of its subfolders).
