Description David Ferguson 2012-02-24 08:32:53 UTC
The following method in the UnixRegistryApi class doesn't support ulong, ushort, bool, etc, when saving data to the registry.

public void SetValue (string name, object value, RegistryValueKind valueKind)

The following code works properly under .NET in windows:

internal static void SetRegistryValue<T>(RegistryKey regKey, Type propertyType, 
string propertyName, T propertyValue)
            if (propertyType == typeof(long) || propertyType == typeof(ulong))
                regKey.SetValue(propertyName, Convert.ToInt64(propertyValue, CultureInfo.InvariantCulture), RegistryValueKind.QWord);
            else if (propertyType == typeof(bool) ||
                propertyType == typeof(byte) ||
                propertyType == typeof(sbyte) ||
                propertyType == typeof(short) ||
                propertyType == typeof(ushort) ||
                propertyType == typeof(int) ||
                propertyType == typeof(uint))
                regKey.SetValue(propertyName, propertyValue, RegistryValueKind.DWord);
                if (propertyValue == null)
                    regKey.SetValue(propertyName, String.Empty);
                    regKey.SetValue(propertyName, propertyValue);

Note the property type of bool being set in the registry as a DWORD.  Also, looking at the code, the QWORD in the UnixRegistryApi doesn't support unsigned longs.

I noticed that the bool type will still fail when using a DWORD

Can you test again, there was a separate fix that took care o f other cases.
Comment 4 Marek Safar 2012-05-30 09:55:30 UTC
Already fixed in master
