Question

I am working on extending the spell checker that has recently been updated on the code gallery: http://code.msdn.microsoft.com/spellCheckerSample

I would like to update it so that the “ignore” list of words comes from CustomDictionary.xml, the same file that the static code analysis tools use.

From within my VS 2010 editor extension, I need to:

1. Find the project in which the current file resides.
2. Find the “CustomDictionary.XML” file, if it exists.
3. If it exists, I need to check it out from source control
4. If it doesn’t exist, I need to add it to the current project (and to the source control)
5. Add text to the CustomDictionary.XML file (this is the easy part).

Is anyone aware of any examples that would help me learn how to do this? I am using the VS2010 Release Candidate.

Thanks.

Here’s what I have so far:

public ISpellingDictionaryService GetSpellingDictionaryService(ITextBuffer textBuffer)
{
    var bufferAdapter = AdaptersFactory.GetBufferAdapter(textBuffer);
    if (bufferAdapter != null)
    {
        var extensibleObject = bufferAdapter as IExtensibleObject;
        if (extensibleObject != null)
        {
            object document;
            extensibleObject.GetAutomationObject("Document", null, out document);
            // Control never gets here... GetAutomationObject appears to recurse.
        }
    }
}

Got it working with a combination of Noah’s help and something I found on the MSDN forums. I’m not sure it would be better to get the DTE object another way, but this is working as far as I can see:

var bufferAdapter = AdaptersFactory.GetBufferAdapter(textBuffer);
if (bufferAdapter != null)
{
    var persistFileFormat = bufferAdapter as IPersistFileFormat;
    if (persistFileFormat != null)
    {
        string ppzsFilename;
        uint iii;
        persistFileFormat.GetCurFile(out ppzsFilename, out iii);

        var dte2 = (DTE2) Shell.Package.GetGlobalService(typeof (SDTE));

        ProjectItem prjItem = dte2.Solution.FindProjectItem(ppzsFilename);

        var containingProject = prjItem.ContainingProject;

        // Now use the containingProject.Items to find my file, etc, etc
    }
}
