Help Converting Some C# Code to Visual Basic...

We're talking 2005 for both languages. Left, Top, Right, Bottom, Height, and
Width are Integers.

C# version:
            public override int GetHashCode()
            {
                return Left ^ ((Top << 13) | (Top >> 0x13))
                  ^ ((Width << 0x1a) | (Width >> 6))
                  ^ ((Height << 7) | (Height >> 0x19));
            }

My VB2005 version:
           Public Overrides Function GetHashCode() As Integer
                Return Left ^ ((Top << 13) OR (Top >> 0x13)) _
                    ^ ((Width << 0x1a) OR (Width >> 6)) _
                    ^ ((Height << 7) OR (Height >> 0x19))
          End Function

I'm seeing a couple of errors, but I think they are all related to the area
around 0x13. Any help would be greatly appreciated.

change the 0x to &H.

See Mattias' comment. There's no way that using "^" will yield the same
results.

In addition to what Tom wrote...

The ^ operator in C# performs an XOR operation, whereas in VB it is
the "power of" operator. So make sure you replace ^ with Xor.

Thanks Matt, that resolved a conversion error I was getting (and
subsequently improperly handling).

VB.2005 is aka VB.NET?

Perhaps you already know this but you can get a lot of help using a
Lutz Roeder's Reflector:
http://www.aisto.com/roeder/dotnet/

It analyzes the common intermediate language and turns it into source
code; f.x. C#, VB.NET and so on. It is really helpful when converting
from one .NET language to another. And just for peeking at source code
in general.
