The VistaBridge project includes API's for many other Vista Features (such as the TaskDialog, Vista OpenFile and SaveFile Dialogs, and of course the Aero Glass Effects) to try these out, run the VistaBridge Project.

This only appears to be an issue with VS2008, and it may have been fixed by the time you are reading this, so try to run the project first, and if you click on one of the 'TaskDialog' buttons and see it popup (ie you dont see an exception) then you do not need to take these steps, if you do get an exception, follow the steps below:

To Run the VistaBridge Project in Visual Studio 2008, you must re-create the Application Manifest file. To do this, open the manifest already in the project, copy all of the text from it to notepad and then delete the manifest file from the project. Next, right click on the "VistaBridgeDemoApp" project and select Add New Item. Choose an Application Manifest File and MAKE SURE you name it as follows: VistaBridgeDemoApp.exe.manifest and then press enter. Now double click on the new manifest file, select all the text and replace it with the text that was copied out of the old manifest. You can now Build the solution and the Demo App should now operate properly. If you still have problems, try closing Visual Studio and then Re-opening it.

When running an application that is GUI from a console window, you may want to echo something to that console window (such as command line options when the user specifies /? on the command line), but also don't want a console window popping up when you don't need it (such is the behavior of a windows C# 'Console Application'). In this case these work great, and are fully compatible thereafter with the .NET Console.xxx static functions.

• Your program will crash if you try to attach when running from windows and not from a console window.

• Your program will start in a different console window if you don't use attach, even if you run from one.

Checks for RemoteDebugger on the 'hProcess'. The "remote" in CheckRemoteDebuggerPresent does not imply that the debugger necessarily resides on a different computer; instead, it indicates that the debugger resides in a separate and parallel process. Use the IsDebuggerPresent function to detect whether the calling process is running under the debugger.

Here's how I use CreateMutex() to prevent more than one instance of my application from running at any given time.

                    // already another instance of this application running.

                        // So, don't allow this instance to run.

                    // once the app is up and running, I log the failure from

                // run the app.

                Application.Run( form );

This implements a Mutex using a Null DACL (with all the security problems with that). This allows the Mutex to be sharable cross-process. In my implementation I access this Mutex from both ASP.Net and a Windows service running under different ids.
