Cannot Open 'CS3 file in CS2' - programmatically handle this dialog

Question

I am running a Visual Basic app that cycles through a collection of InDesign documents performing actions. We are using CS2 and the problem occurs when a CS3 document is encountered, which hangs the app. When opening the file manually the following error dialog is encountered:
Cannot open "xxxx.indd". Please upgrade your plug-ins to their latest versions, or upgrade to the lastest version of Adobe InDesign.
InDesign is launched by:
appInDesign = CreateObject("InDesign.Scripting.CS2")
User interaction is suppressed:
appInDesign.ScriptPreferences.UserInteractionLevel = InDesign.idUserInteractionLevels.idNeverInteract
Documents are opened by:
docInDesign = appInDesign.Open(<FilePath>, False)
How do you handle/identify this dialog/error without user interaction (I would like to skip the file)?
Thanks in advance

Answer 1

If you opening CS3 file in CS2 you alway get error message.
I think best solution is check indesign document version before opening it.
I have code for checking indesign version but it is Javascript code.
But it will give you idea how you can check indesign version and skip that files.
Here below is code:
f = File.openDialog ('Select file', undefined, false);
alert('Indesign version: '+getFileVersion(f));
function getFileVersion(f){
var IDVersion;
f.open('r')
f.seek(29, 0)
IDversion = f.readch().charCodeAt(0);
f.close();
return (IDversion);
