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

Nice Code Shonky

I think this is what you are looking for Martin;

var docInDesign, f;
f = File.openDialog ('Select file', undefined, false); 
 
if (getFileVersion(f) != 4){
 
 alert ("Can not open the file, Indesign Version: is " + getFileVersion(f))
 }
else {
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT
docInDesign = app.open(f);
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL
}

function getFileVersion(f){ 
var IDVersion; 
f.open('r') 
f.seek(29, 0) 
IDversion = f.readch().charCodeAt(0); 
f.close(); 
return (IDversion); 
}

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); 
}
