Develop a new connection type

Last updated on Apr 27, 2021

The following steps outline the process for creating a new connection type:

Create the layout for the connection dialog box.

Create an HTML file that lays out the user interface (UI) for your connection dialog box. Name this file using the name of the connection (for example, myConnection.htm). For information about creating a dialog box, see Getting Started with Dreamweaver.

Make sure this HTML file includes a reference to the JavaScript implementation file that you define in Step 2, Create a JavaScript file that implements at least the following elements, as shown in the following example:
```
 <head> 
    <script SRC="../myConnectionImpl.js"></script> 
</head>
```
Store this HTML file, which defines your connection dialog box, in the Configuration/Connections/server-model/platform folder (where the platform is either Windows or Macintosh).

For example, the default ADO connection dialog box for an ASP JavaScript document on a Windows platform is stored in the ASP_Js/Win folder and is named Connection_ado_conn_string.htm.

Note:

At runtime, Dreamweaver dynamically builds the list of connection types that are available to the user from the collection of dialog boxes that are in the ASP_Js/Win folder.

The Configuration/ServerModels folder has HTML files that define each server model. Inside each HTML file is the getServerModelFolderName() function, which returns the name of the folder that is associated with the server model. The following example shows the function for the ASP JavaScript document type:
```
 function getServerModelFolderName() 
{ 
    return "ASP_JS"; 
}
```
You can also look at the MMDocumentTypes.xml file, which is located in the Configuration/DocumentTypes folder, to determine the mapping between server models and document types.

Create a JavaScript file that implements at least the following elements:

Element	Description	Examples
A set of variables	Each variable defines a specific connection property	Type of connection, data source name, and so on
A set of buttons	Each button appears in the connection dialog box	Test, Help, and so on (OK and Cancel are automatically included)
Connectivity functions	Together, these functions define the Connectivity API	findConnection() applyConnection() inspectConnection()

You can select any name for this implementation file, but it must have a .js extension (for example, myConnectionImpl.js). You can store this implementation file on either your local or a remote computer. You might want to store your implementation file in the appropriate subfolder within the Configuration/Connections folder.

Note:

The HTML file that you defined in Step 1, Create the layout for the connection dialog box, must include this connection type implementation file.

Unless you need to define connection parameters other than the ones provided in the standard connection_includefile.edml file, these two steps are the minimum to create a new connection dialog box.

Note:

The title of the dialog box that the user sees is in the title tag, which is specified in the HTML document.

The functions listed in the next section let you create a connection dialog box. Along with implementing the calls for generating include files for the user, you can register your connectivity type within the server model section of the connection XML file.
