I was trying to read a simple registry keyvalue using the below code:
Dim aa As Object
aa = Registry.GetValue("HKEY_CURRENT_USER\\Software\\Avira\\AntiVir Desktop", "LastCommandLine", Nothing)

aa variable value is always Nothing.

What am I doing wrong here?
Please advise.

Then I tried the same in C# code and its working fine.
The code is As below:
object  aa = Registry.GetValue("HKEY_CURRENT_USER\\Software\\Avira\\AntiVir Desktop","LastCommandLine",null);

Dim aa As Object
       aa = Registry.GetValue("HKEY_CURRENT_USER\Software\Avira\AntiVir Desktop", "LastCommandLine", Nothing)

Can you see why? The key value you really need is "HKEY_CURRENT_USER\Software\Avira\AntiVir Desktop"; and the double '\\' simply means escaped '\', by C# syntax, not VB.NET. To make C# code similar, use verbose modifier '@':
object aa = Registry.GetValue(@"HKEY_CURRENT_USER\Software\Avira\AntiVir Desktop","LastCommandLine", null);

Better now? :-)
