adding or modifing hyperlinks via 


HyperLinkCollection hyperLinkCollectrion = entity.Hyperlinks;

HyperLink hyperLink = new HyperLink();
hyperLink.Name = filename
hyperLink.SubLocation = filename


works fine. But it seems that the file to link must exist. If the file does not exist, I cannot modify a hyperlink. With the command HYPERLINK in AutoCAD the file must not exist.


Is my observation true or is it a fault I made?

Hi Wolfgang,


Sorry for the delay.


I dont think there is any such requirement while adding a hyperlink.

AutoCAD tries to resolve the actual path only when you click on the entity with Ctrl pressed.


Using this code, I could add a hyperlink to a file that did not exist and AutoCAD displayed the error message only when the entity was clicked.


HyperLink hyperLink = new HyperLink();
hyperLink.Description = "My File";
hyperLink.Name = "..\\..\\..\\..\\..\\..\\..\\..\\Temp\\5.txt";
hyperLink.SubLocation = "";
