Hi All Hope you can help as I am stumped.
I have a web page developed using Visual Studio 2008/C#. .Net install level on the Web server is set to 3.5 SP1. The page reads a directory (at the moment it is reading the web server c drive) and displays the contents of the directory in a treeview component. No problem there so far. My problem is that the documents will not open in either Firefox or More importantly IE (our default). However that actions are different in the browsers. In firefox The error "Firefox doesn't know how to open this address, because the protocol (c) isn't associated with any program" is displayed. In IE the file just does not open. Nothing appears to happen. A sample of the links on a tree node are c:\temp\Websites.txt c:\OpenManage\docs\en\OpenManage_IS_UG\instlx10.jpg I can normally open .txt, .jpg and other file types using either browser. My code is listed below. Thanks in advance for Any help which will be most gratefully received.
