I tried to break linking for about 1/2 hour and failed to repeat your error, without recalculating the sheet and without $Book->UpdateLink({Name=> $Book->{LinkSources}}); So, allow me to suggest a course of action, if you please.

Debug a little using Win32::OLE->LastError(). After you try to open your files, print Win32::OLE->LastError()."\n";, after you try to get the values, print Win32::OLE->LastError()."\n"; You get the idea.

Something is happening that you are making assumptions about, and I think somewhere your assumptions are wrong, or as Inigo would say "I do not think it means what you think it means."

Perhaps if you built an example that breaks but doesn't use proprietary files such that you could post the code. As I say, I tried to replicate your error using the code given without any luck, and I can post my code if you like to double check my understanding vs. your meaning.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
