file-association

When I was working with file association in a .NET application I hadn't had found a way to set it without UAC popping up a confirmation dialog. Today, when I opened uTorrent and looked up for file association, I've found that you can enable (writing to registry) without any confirmation from the UAC. How is that possible? uTorrent is not running as an admin. Edit: Well, I have just discovered with Process Monitor (Sysinternals) that what uTorrent.exe does is to create a few keys ( uTorrent and .torrent ) but in HKCU ( HKEY_CURRENT_USER ), not in HKEY_CLASSES_ROOT . Anyways I also have those

After playing around with a new Windows Form project, I discovered that when you associate a file type with an executable in Windows, you can find the file path of the file that launched the application using args[0] from static void Main(string[] args) Is it possible to launch an event on your application when you double click a file if your application is already open? (As obviously Main(string[] args) won't be triggered). Example of an application with behavior I am attempting to replicate: User Opens GIMP(in Windows) User opens explorer and right clicks a .png file User selects open with

My users can attach documents to various entities in the application. Of course, if user A attaches a .TIFF file, user B may not have a viewer for that type of file. So I'd like to be able to bring up this dialog: alt text http://www.angryhacker.com/toys/cannotopen.png My application is C# with VS2005. Currently I do Process.Start and pass in the file name. If no association is found, it throws an exception. This should do it: System.Diagnostics.Process p = new System.Diagnostics.Process(); p.StartInfo.FileName = "rundll32.exe"; p.StartInfo.Arguments = "shell32.dll,OpenAs_RunDLL " +

I am trying to open and print files with the ProcessStartInfo class. (File can be anything but let`s assume it is a PDF File) ProcessStartInfo pi = new ProcessStartInfo(file); pi.Arguments = Path.GetFileName(file); pi.WorkingDirectory = Path.GetDirectoryName(file); pi.Verb = "OPEN"; Process.Start(pi); this works well for the pi.Verb = "OPEN"; . Some applications register themselves also with the verb "PRINT" but only some do. In my case (Windows PDF Viewer) I get an exception when trying to execute with the pi.Verb = "PRINT"; Is there a way to see all the verbs available for a specific type in

My .Net Windows Forms application generates a PDF report, which I want to show to the user. Instead of just assuming the client PC has a PDF viewer installed and blindly throwing the PDF at the Operating System to open, is there a way to check against the list of file associations on the client beforehand, then show a " you need a PDF viewer application installed - here's a couple of suggestions.. " dialog if PDF isn't a registered type? I've found a lot of questions and answers about changing or registering file associations, but I just want an easy way to query the list, not change it. I'd
