How to edit the source of a power query using VBA?
<p>I am trying to edit the source of one of my queries using VBA. This is what I have so far:</p>

<pre><code> Dim mFormula As String

 mFormula = _

 "let Source = Excel.Workbook(File.Contents(wbname), null, true) in Source"

 query1 = ActiveWorkbook.Queries.Add("LATEST", mFormula)
</code></pre>

<p>I set <code>wbname</code> previously in my code.  "LATEST" is already added, instead of delete it and read it, I would just like to change the source. Is this possible?</p>
