  I'm writing a program to enum all the physical drives in the system (to examine unmounted drives), however my CreateFile call isn't returning a valid handle: SafeFileHandle driveHandle = CreateFile( string .Format( @"\\.\PHYSICALDRIVE{0}" , drive_index), GENERIC_READ, 1, IntPtr .Zero, OPEN_EXISTING, uint .MinValue, IntPtr .Zero); After checking the LastError I find that the error is "Access Denied", how can I get my program access to do this Update: After running the Application Verifier I find I'm hitting this problem: Object opened/created in a restricted namespace I have a feeling I need to change the runLevel in the manifest, but I can't find any pages with examples of how to do this, just pages talking about making ...Show All

• .NET Development File Access and reading into a data structure

  Hi, I am trying to read text files into a data structure. I have a directory to get the files from, and I want to basically read all files from the directory and parse them based on a data structure that I set up. I have the code already to search the directory, and to open and read the files, but I am wanting to know if there is an easy way to read the files into a data structure. Here's the code that I have already. [code] StreamReader _sr = _dirInfoObj.GetFiles(); do { lineData = _sr.ReadLine(); } while (lineData != null); [/code] What I want is to pass LineData to another function and have it parsed or just readline directly into a data structure.

• Visual Studio Self-contained Embedding

  Is it possible to make a self-contained embedding as AClass->BClass->AClass At present there are quite severe restrictions on the domain models that we support.  Every class can only be embedded once; and every class that can have a shape on the toolbox must be embedded in the root class.  The consequence of this is that the shape you propose is not supported.  These restrictions will be relaxed in our V1 release.

• Internet Explorer Development IShellWindows behaviour changed under Windows Vista?

  Hi After a bit of experimenting, it seems to me like IShellWindows only enumerates "true" Shell Windows under Vista. Internet Explorer Windows are ignored, unlike in previous Windows versions. Is there another way to enumerate all open Internet Explorer windows in Vista and accessing their IWebBrowser interface Thanks in advance, Robert I am not aware of any difference. I ran this sample jscript which enumerates the windows and it was able to retrieve information regarding IE windows too.
