Setting cursor position with Visual Studio Extension

Question

I'm writing my own Visual Studio 2010 Extension that should help me navigating a rather large solution.
I already have a dialog based VS Extension that shows me a class name and a function name depending on some search criteria. I now can click this class/method and I then already can open the correct file and jump to the function.
What I now want to do is to set the cursor at the start of that function.
My code to jump to the function is:

Solution currentSolution = ((EnvDTE.DTE)System.Runtime.InteropServices.Marshal.GetActiveObject("VisualStudio.DTE.10.0")).Solution;
ProjectItem requestedItem = GetRequestedProjectItemToOpen(currentSolution.Projects, "fileToBeOpened");
if (requestedItem != null)
{
    // open the document
    Window window = requestedItem.Open(Constants.vsViewKindCode);
    window.Activate();

    // search for the function to be opened
    foreach (CodeElement codeElement in requestedItem.FileCodeModel.CodeElements)
    {
        // get the namespace elements
        if (codeElement.Kind == vsCMElement.vsCMElementNamespace)
        {
            foreach (CodeElement namespaceElement in codeElement.Children)
            {
                // get the class elements
                if (namespaceElement.Kind == vsCMElement.vsCMElementClass)
                {
                   foreach (CodeElement classElement in namespaceElement.Children)
                   {
                       try
                       {
                           // get the function elements
                           if (classElement.Kind == vsCMElement.vsCMElementFunction)
                           {
                               if (classElement.Name.Equals("functionToBeOpened", StringComparison.Ordinal))
                               {
                                   classElement.StartPoint.TryToShow(vsPaneShowHow.vsPaneShowTop, null);
                                   this.Close();
                               }
                           }
                       }
                       catch
                       {
                       }
                   }
               }
           }
       }
   }
}

The important points here are window.Activate(); to open the correct file and classElement.StartPoint.TryToShow(vsPaneShowHow.vsPaneShowTop, null); to jump to the correct function.
Unfortunately the cursor is not set to the start of the requested function. How can I do this? I'm thinking of something like classElement.StartPoint.SetCursor().

Cyclomatically complex? Also, looks like you aren't bailing out of the method when you find what you're looking for, which might have some side effects (WAG). – Stutman

@Will: Yes, I know. This is just some kind of prototype code. Just for demonstrating how I open the requested class and function... – Aleut

I finally got it...
You just have to use the TextSelectioninterface where you have the method MoveToPoint.
So the code from above is now:

// open the file in a VS code window and activate the pane
Window window = requestedItem.Open(Constants.vsViewKindCode);
window.Activate();

// get the function element and show it
CodeElement function = CodeElementSearcher.GetFunction(requestedItem, myFunctionName);

// get the text of the document
TextSelection textSelection = window.Document.Selection as TextSelection;

// now set the cursor to the beginning of the function
textSelection.MoveToPoint(function.StartPoint);
