Registry Entries for Debugger Languages Options

The VS Reg Root\Languages\Language Services\Language Name\Debugger Languages\GUID\ key can include the following values.

Name	Type	Range	Description
(Default)	REG_SZ	text	The default value can be used to document the name of the language. The name of this key is a GUID of an expression evaluator that has a corresponding entry in <VS Reg Root>\AD7Metrics\Expression Evaluator.

Registry Entries for Editor Tools Options

You can add registry keys under the EditorToolsOptions key for property pages and property nodes. These keys and their values identify property pages in the Options dialog box (on the Tools menu) that are used to configure the language service. In the following example, Page Name is the name of a property page, and Node Name is the name of a node in the tree on the Options dialog box. The page entry and the node entry must be specified separately.

Name	Type	Range	Description
(Default)	REG_SZ	ResID	The localized display name of this option page. The name can be literal text, or #nnn, where nnn is a string resource ID in the satellite DLL of the specified VSPackage.
Package	REG_SZ	GUID	The GUID of the VSPackage that implements this options page.
Page	REG_SZ	GUID	The GUID of the property page to request from the VSPackage by calling the GetPropertyPage method. If this registry entry is not present, the registry key describes a node, not a page.

Example

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\
  Languages\
    Language Services\
      CSharp\
        EditorToolsOptions\
          Formatting\
            (Default) = reg_sz:#242
            Package   = reg_sz:{A066E284-DCAB-11D2-B551-00C04F68D4DB}
            General\
              (Default) = reg_sz:#255
              Package   = reg_sz:{A066E284-DCAB-11D2-B551-00C04F68D4DB}

              Page      = reg_sz:{607D8062-68D1-41E4-9A35-B5E7F14D0481}

Registry Entries for File Name Extension Options

The entry for the file extension should include the leading period, for example ".myext".

Name	Type	Range	Description
(Default)	REG_SZ	GUID	Service GUID for the default language service for this file name extension type.

Example

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\
  Languages\
    File Extensions\
      .cpp\
        (Default) = {B2F072B0-ABC1-11D0-9D62-00C04FD9DFD9}

Registry Entries for Editor Options

The VS Reg Root\Editors key can contain the following values:

Name	Type	Range	Description
(Default)	REG_SZ	""	Unused; you can put your name here for documentation.
DefaultToolboxTab	REG_SZ	""	Name of the toolbox tab to make default when the editor is active.
DisplayName	REG_SZ	ResID	Name to display in the Open With dialog box. The name is the string resource ID or a name in standard format.
ExcludeDefTextEditor	REG_DWORD	0-1	Used for the Open With menu command. If you do not want to list the default text editor in the list of available editors for a specific file type, set this value to 1.
LinkedEditorGUID	REG_SZ	<GUID>	Used for any language service that can open a file with codepage support. For example, when you open a .txt file by using the Open With command, options are provided for using the source code editor with and without encoding. The GUID specified in the name of the subkey is for the codepage editor factory; the linked GUID specified in this specific registry entry is for the regular editor factory. The purpose of this entry is that if the IDE does not open a file by using the default editor, the IDE will try to use the next editor in the list. This next editor should not be the codepage editor factory because this editor factory is basically the same as the editor factory that failed.
Package	REG_SZ	<GUID>	VSPackage GUID for the display name's ResID.

Example

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\
  \Editors\
    {8281C572-2171-45AA-A642-7D8BC1662F1C}\
      (Default)            = reg_sz:Html Editor with Encoding
      DefaultToolboxTab    = reg_sz:HTML
      DisplayName          = reg_sz:#20101
      LinkedEditorGUID     = reg_sz:{C76D83F8-A489-11D0-8195-00A0C91BBEE3}
      Package              = reg_sz:{1B437D20-F8FE-11D2-A6AE-00104BCC7269}

Registry Entries for Logical View Options

The VS Reg Root\Editors\Editor GUI>\LogicalViews key can contain the following values.

Name	Type	Range	Description
(Default)	REG_SZ		Unused.
<GUID>	REG_SZ	""	Key to the logical views supported. You can have as many of these as you need. The name of the registry entry is what is important, not the value, which is always an empty string.

Example

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\
  \Editors\
    {8281C572-2171-45AA-A642-7D8BC1662F1C}\

Registry Entries for Editor Extension Options

The VS Reg Root\Editors\Editor GUID\Extensions key can contain the following values. The file name extension does not include the leading period.

Name	Type	Range	Description
(Default)	REG_SZ		Unused.
<ext>	REG_DWORD	0-0xffffffff	Relative priority of extensions. If two or more languages share the same extension, the higher-priority language is chosen.

Additionally, the current user's default selection for an editor is stored in HKEY_Current_User\Software\Microsoft\VisualStudio\X.Y\Default Editors\ext. The GUID of the selected language service is in the Custom entry. This takes precedence for the current user.

Example

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\
  \Editors\
    {8281C572-2171-45AA-A642-7D8BC1662F1C}\
