Being new to vb (actually vba) I've have come across the following brickwall:

I'm writing code in xl which is activated when the file with the code is opened. Problem is this:

I'm trying to open another XL file (which has links to and from the file with the code), update the links to that file and close and save changes. This in turn, updates the links in the file with the code. Both files are extremely sizeable and, for a variety of reasons, must remain separate.

Works fine except when another user on the network is in the file that is being opened by the code. If there is another user in the file I am happy for the links not to be updated and for the file to simply be closed.

Is there code which will tell you whether the file is in use and "locked for editing", which you can use in, say, an IF statement, to circumvent errors?

Any assistance you gurus out there can give me will be appreciated. Just want to say that this site is GREAT!
