The code snippet below (from the AutomateAuthenticDesktop example; see the file Form1.cs) shows how to iterate through open documents. A condition is then tested within the iteration loop, and the document view is switched between Text View and Authentic View.
// Handler for the "Toggle View Mode" button
private void toggleView_Click(object sender, EventArgs e)
// Make sure there's a running Authentic Desktop instance, and that it's visible
// Iterate through all open documents and toggle the current view between Text View and Authentic View.
foreach (XMLSpyLib.Document doc in AuthenticDesktop.Documents)
if (doc.CurrentViewMode == XMLSpyLib.SPYViewModes.spyViewAuthentic)
The AutomateAuthenticDesktop example example is located in the C# folder of the API Examples folder:
Windows 7, Windows 8, Windows 10
