2.6 Changing Editors


When
you open a file, Visual Studio .NET chooses which editor to use based
on the file's extension. However, it is sometimes
useful to edit that file with a different editor. For example, when
you open an .asmx file, the default editor will
let you edit only either the design view or the associated codebehind
file. It will never show you the contents of the
.asmx file itself. If you want to edit the
.asmx file directly, you need to open it with
the text editor. You can open any file in a project with the editor
of your choice by selecting it in the Solution Explorer and then
selecting View Open With.... (You can also select
Open With... from the file's context menu in the
Solution Explorer.) This will display the dialog box shown in Figure 2-11.

From this dialog you can edit the file with any editor in the
listbox. The editor with the (Default) tag after it is the default
editor for the chosen document. You can change the default editor by
selecting one from the list and clicking on the Set as Default button
on the dialog box.

You can also use this dialog to add additional programs to the list
of editors. Pressing the Add button displays a dialog box in which
you can enter the path and name of an application. When you select
that editor, VS.NET will spawn that application and pass the
currently selected document to it.


2.6.1 Specifying an Encoding


The Visual Studio .NET text editor supports multiple character sets.
Visual Studio .NET usually guesses which encoding should be used when
opening files, but the Open With dialog box allows you to override
its decision. As Figure 2-11 shows, some of the
entries in the Open With list have the text "With
Encoding" after them. If you select any of these,
the Encoding dialog box (see Figure 2-12), which
allows you select a specific encoding, will appear.

You can also choose an encoding when you save a document. If you
select File Save As, the Save File dialog box will
appear. The Save button has a drop-down list, from which you can
select Save with Encoding..., which will display the Advanced Save
Options dialog box (see Figure 2-13). From this, you
can choose an encoding scheme, and you can also select the way in
which line endings are stored. (You can choose CR, LF, or CRLF.)
