How can I get a full list of the XReferences even some of them can't be loaded ?

Hello.
You can get the full list of XReferences using CADImage.Converter.XRefs property

Thanks for your reply. I'm using following code to count the number of XREF:

Code: Select all

        Dim sFullName As String = "D:\Desktop\drawing1.dwg"
        Dim dwg As CADImage = CADImage.CreateImageByExtension(sFullName)
        dwg.LoadFromFile(sFullName)
        Dim n As Integer = dwg.Converter.XRefs.Count

The file "drawing1.dwg" actually has a xref "drawing2.dwg". If I place the xref "drawing2.dwg" in the path where can be located by "drawing1.dwg", then the above code shows me "1" - there is one xref. But if I place the xref in somewhere can't be located, then the above code shows me "0". The result I want the program to show me is there is one xref but it is missing. How can I get this result?

XRef object is a block that is loaded from a file by reference. In your example "drawing1.dwg" doesn't contain "drawing2.dwg" but only reference to it. When loading, if this reference not valid, XRef can't be loaded and ignored.
