Comment and Uncomment fail on one document

Posted 9 years ago by Bob Puckett

Version: 15.1.0622

I have multiple tabbed docs. I have most things working (cut, paste, etc.). Indent and Outdent work.

But, I have a problem with comment and uncomment in the first doc tab, but it works fine in all others.

my Editor control has this code:

public void EditorAction(IEditAction action)
{
bool result = mySyntaxEditor.ActiveView.ExecuteEditAction(action);
}

my application form has this code:

private void myCodeCommentBlockButton_ItemClick(object sender, ItemClickEventArgs e)
{
activePythonEditor.EditorAction(new CommentLinesAction());
}

private void myCodeUncommentBlockButton_ItemClick(object sender, ItemClickEventArgs e)
{
activePythonEditor.EditorAction(new UncommentLinesAction());
}

When I try this on the first doc (which is created slightly differently), the result comes back as false. But all other commands work fine. And, this works fine on other created tabs. All highlighting and intellisense is working.

Any ideas why this might fail?

Hi Bob,

The ExecuteEditAction returns false if the related action's CanExecute method returns false. The CommentLinesAction.CanExecute method returns false when the document is read-only, doesn't have a language, or the language doesn't have an ILineCommenter service. Check all those conditions to see where the problem is in your case.

Hi,

I'm taking over where Bob left off. This issue of adding comments still persists for our "Simple Script" language. I've modified to source that comments lines to check 'CanExecute', and 'CanExecute' always returns false. The language definition I have created includes comments (they begin with '* '). Any ideas what else I can check?

        private void CodeCommentBlockButton_ItemClick(object sender, ItemClickEventArgs e)
        {
            CommentLinesAction action = new CommentLinesAction();

            IEditorView view = activeSyntaxEditor.m_SyntaxEditor.ActiveView;

            if (action.CanExecute(view))
                activeSyntaxEditor.EditorAction(new CommentLinesAction());
        }

Thanks,
Nate
