None of the BinaryWriter constructs support new BinaryReader
BinaryWriter Constructors

BinaryWriter()()() Initializes a new instance of the BinaryWriter class that writes to a stream.

BinaryWriter(Stream) Initializes a new instance of the BinaryWriter class based on the supplied stream and using UTF-8 as the encoding for strings.

BinaryWriter(Stream, Encoding) Initializes a new instance of the BinaryWriter class based on the supplied stream and a specific character encoding.

More like:

...
using(BinaryWriter binWriter =
    new BinaryWriter(File.Open(fileName, FileMode.Create)))
{
    binWriter.Write(aspectRatio);
    binWriter.Write(lookupDir);
    binWriter.Write(autoSaveTime);
    binWriter.Write(showStatusBar);
}
...

Change registry key in Vista

Hi,

We have a number of computers (>300), for which we need to change a particular registry setting. So I wrote a C# program that uses this code to do that:

RegistryKey regkey = Registry.LocalMachine.OpenSubKey(KeyName, true);
regkey.SetValue(KeyValue, 2);

When I distribute the executable, it works perfectly for all XP machines. But the Vista machines (even while in user accounts with Admin access) throw an error:

System.Security.SecurityException: Requested registry access is not allowed

I've tried looking for solutions online but couldn't follow any. Anyone who can help me change a registry key value in Vista through C# code?

Thanks,

Sarab

To run it on Vista, right click on the application and select "Run as administrator".

In addition to what Guffa said, these may help.
Look at the System.Security.Permissions.RegistryPermission class
and/or
Add an app.manifest file and alter the requestedExecutionLevel - this will invoke UAC.

Use the "Text" member for your control, e.g. myTextBox.Text. This is a string that gets/sets the text for the control.

How to turn off UAC using c#?

Not that I can say for sure, but I would imagine that its close to impossible - the point of UAC is to stop programs doing things they shouldn't. If C# could turn it off easily I'd be very worried about UACs value as a security measure...

You probably shouldn't, but, all the UAC stuff is saved in the registry. You can alter those keys (you'll need to invoke UAC via app.mainifest first to be able to access them) from C#. Google for Registry UAC Vista and you should be able to find out which keys they are.

Not sure if from a security standpoint that this is a good idea. Any reason why you must do this?

MONO is an open source development for porting .NET libraries to other platforms. Try to compile your application with MONO. Keep it in mind, MONO is developed by open source community and it won't support latest .NET framework classes. I believe it has support till framework 2.0,

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia
