Checking if a document is already open

[Lucas02]

Our Design department is having a permissions problem with InDesign not creating Lock files on our AFP Server.

I am looking to use an InDesign script that checks if the current file is already in use.

Any help would be appreciated.

Is this help?

var doc1=File.openDialog ("Choose your file",true)
try{
app.open(doc1);
}
catch(e){alert("File already opened")}

I think you don't need to provoke an error to achieve that.

function checkIfSomeFileIsOpened ( someUrl ) {
var docs = app.documents.everyItem().getElements(),
n = docs.length, docUrl, doc, checkFileUrl = File (someUrl).absoluteURI ;
if ( !n) return false;
while ( n--  ) {
doc = docs;
url = doc.properties.fullName;
if ( File ( url ).absoluteURI == checkFileUrl ) {
return true;
}
}
return false;
}
var url = "/Users/ozalto/Desktop/test1.indd";
checkIfSomeFileIsOpened ( url );
