6. How to write a save module script

In the example of this tutorial, we created a new Save Module file dialog box. There are several templates in hotmetal that you can choose from. The template is just an ordinary Web page that is saved HoTMetaL the template template in the application directory. When you select a new item from the File menu, one of the label options is page from Template. When you select it, a tabbed dialog box pops up with a variety of templates: general, WebTV, the wide-range, Frame Pages, Layout.

You can create a new template by saving the current file to a directory in the template directory. The following macro, the Save As template, shows you how to create a Save As dialog box using the Hmextras.filedlg Displayfiledlg method. This dialog box uses the template directory as the default location, with the following detailed code:

<macro name= "Save as Template" lang= "JScript" id= "><!" [cdata[

var obj = new ActiveXObject ("Hmextras.filedlg");

var filter = "Web Page Template (*.htm, *.html) |*.htm;*.html| All Files (*.*) |*.*| | ";

if (obj. Displayfiledlg (0, "File Save as", filter, Application.path + "\\Template")) {

Activedocument.saveas (obj. Fullpathname, True); Save and put on recent file list

}

]]></macro>

Let's explain the code above: first, we use the Hmextras Library's Filedlg COM object to create an ActiveX control:

var obj = new ActiveXObject ("Hmextras.filedlg");

Then use several entries to create a filter:

var filter = "Web Page Template (*.htm, *.html) |*.htm;*.html| All Files (*.*) |*.*| | ";

Then we call obj by calling. Displayfiledlg to display the file dialog box, and finally we save the file if the dialog box exists.
