Opens an existing file and allows you to specify an editor.
Syntax
File.OpenFile filename [/e:editorname]
Arguments
filename
Required. The full or partial path and file name of the file to open. Paths containing spaces must be enclosed in quotation marks.
Switches
/e:editorname
Optional. Name of the editor in which the file will be opened. If the argument is specified but no editor name is supplied, the Open With dialog box appears.
The /e:editorname argument syntax uses the editor names as they appear in the Open With Dialog Box, enclosed in quotation marks.
For example, to open a file in the source code editor, you would enter the following for the /e:editorname argument.
/e:"Source Code (text) Editor"
Remarks
As you enter a path, auto completion tries to locate the correct path and file name.
Example
This example opens the style file "Test1.css" in the source code editor.
>File.OpenFile "C:\My Projects\project1\Test1.css" /e:"Source Code (text) Editor"
