CHAPTER 21

C-Level Extensibility

The C-level extensibility mechanism lets you implement Macromedia Dreamweaver MX

extensibility files using a combination of JavaScript and your own C code. You define functions

using C, bundle them in a DLL or shared library, save the library in the Configuration/

JSExtensions folder within the Dreamweaver application folder, and then call the functions from

JavaScript using the JavaScript interpreter that is built into Dreamweaver.

For example, you might want to define a Dreamweaver object that inserts the contents of a user-

specified file into the current document. Because client-side JavaScript does not provide support

for file I/O, you must write a function in C to provide this functionality.

You can use the following HTML and JavaScript to create a simple Insert Text from File object.

Notice that the

objectTag() function calls a C function named readContentsOfFile(), which

is stored in a library named

myLibrary.

<HTML>

<HEAD>

function objectTag() {

fileName = document.forms[0].myFile.value;

return myLibrary.readContentsOfFile(fileName);

}

</SCRIPT>

</HEAD>

<BODY>

<FORM>

Enter the name of the file to be inserted:

</FORM>

</BODY>
