Xref Found At or Resolved Path

[cbutler1]

Using VB .NET we're trying to find the Resolved path of an Xref. We can get the Saved path (which, for us, is only the xref dwg name) but we need to determine where the Xref was "found at" by AutoCAD.

If someone can point us to the right object, it would be greatly appreciated.

Thanks in advance,

Craig.

Check out the ' FindFile ' method. Here is how I called it in one of my routines.

HostApplicationServices.Current.FindFile(FilePath, db, FindFileHint.Default)

Where ' FilePath ' = path to search ( could be just a drawing name )
db = Database to search with reference to

I think there is a ' FindFileHint ' for Xref, but I'm not sure.

Thanks for the suggestion.

Findfile doesn't help if we're using the "Project Files Search Path" for locating Xrefs vs the "Support Files Search Path". Things start getting ugly. I was hoping that since the location information is available and known to AutoCAD there'd be a way to access it directly.

Is there a FindFileHint for projects? I don't know, as I don't use projects. If not, then you could roll your own.

Nevermind the first part of the previous reply. It makes no sense. Not sure what I was thinking.

I think you will have to roll your own find file if one doesn't exist with the project search path.

I saw this thread when I have the problem. The solution is found out of this disscussion group:

        '-----------The key is db.ResolveXrefs, otherwise the Database of the Xref will be Nothing
	db.ResolveXrefs(False, False)
        Dim XrGph As XrefGraph = db.GetHostDwgXrefGraph(True)
        For i As Integer = 1 To XrGph.NumNodes - 1
                Dim XrGphNode As XrefGraphNode = XrGph.GetXrefNode(i)
		'------- the found path of the Xref is available now
                dim foundpath as string =XrGphNode.Database.Filename
        Next

 For anyone who has this problem...
