问题
I would like to add a custom command to the context menu of each node that appears for every table in a sql server database listed in the Server Explorer.
I've gone through a basic tutorial and added a command to the tools menu bar as well as a custom top level menu.
I've also seen the tutorial Extending the Server Explorer to Display Web Parts which is very close to what I want to do, but it is specific to the sharepoint connections node, and uses the sharepoint specific IExplorerNodeTypeExtension interfaces. I'm having trouble finding any documentation pertaining to the data connections node. Can anyone provide any references to relevant documentation or information on what interfaces I should be leveraging?
回答1:
With some hints from Jack Zhai and a few other web resources I was able to track down information.
- Stack Overflow - Context menu for Server Explorer
- MSDN blog - How to add custom menu to vs editor window
- MSDN Blog - Using EnableVSIPLogging to identify menus and commands with VS 2005
So first, I enabled VSIPLogging by setting the EnableVSIPLogging to 1 in Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\VisualStudio###\General
Then I was able to determine what the guids and ids of any menu item or tree node in Visual Studio by holding down CTRL + SHIFT and right clicking on it.
From this I was able to determine that the top level nodes in the server explorer had a Guid of {74D21310-2AEE-11D1-8BFB-00A0C90F26F7} with a command id of 1283.
Object nodes in the server explorer (such as Tables, stored procedures, etc) have a Guid of {d4f02a6a-c5ae-4bf2-938d-f1625bdca0e2} and a command id of 33280 (0x8200)
Object node parents in the server explorer (such as the static "Tables", "Stored procedures", nodes that categorize the object nodes) have a guid of {d4f02a6a-c5ae-4bf2-938d-f1625bdca0e2} and a command id of 33024 (0x8100)
So with these Guids I can now attach my commands where I want.
I want a command that is specific to an individual table, and a command that is specific to all tables in the database so I will use a d4f02a6a-c5ae-4bf2-938d-f1625bdca0e2 with command id of 0x8200 and a Guid of d4f02a6a-c5ae-4bf2-938d-f1625bdca0e2 with command id of 0x8100.
Next I need to define these values in my vsct file of my VSIX project so I add them to the symbols section:
I add 2 command items to my project and then I need to change the parent of the groups so they appear on the correct area in the server explorer:
Now, the database command does appear for all static object nodes, even though I want it to only appear on the "Tables" node, and the table command appears for all object nodes and their, even though I want it to appear only for the table node itself. I believe that needs to be solved in code somehow, dynamically determining the visibility of the command menu item, but I'll have to figure that one one separately.
Below is the vsct in its entirety:

<!-- The VSCT compiler (the tool that translates this file into the binary

on the vsct file; this preprocessor is (usually) the C++ preprocessor, so
it is possible to define includes and macros with the same syntax used
in C++ files. Using this ability of the compiler here, we include some files
defining some of the constants that we will use inside the file. -->

called "command set" and is used to group different command inside a logically related
group; your package should define its own command set in order to avoid collisions
with command ids defined by other packages. -->

must be the actual index (1-based) of the bitmap inside the bitmap strip. -->
