Using standard .Net libraries with VBA

Question

I have successfully been able to run my own .Net code by following the steps posted here Execute .NET 3.0 code from Office 2003

Is there a way to use the standard .N

Answer 1

You should be able to use ComVisible .NET classes in this way. However the GenerateKey and GenerateIV methods don't have a return value. Try:

Sub Macro1()
   Dim aesImplementation As New RijndaelManaged

   aesImplementation.GenerateKey
   Key = aesImplementation.Key
   aesImplementation.GenerateIV
   IV = aesImplementation.IV
End Sub

or better, not least because when debugging you can see whether an error occurs during construction or when you call the method:

Sub Macro1()
   Dim aesImplementation As RijndaelManaged
   Set aesImplementation = New RijndaelManaged

   aesImplementation.GenerateKey
   Key = aesImplementation.Key
   aesImplementation.GenerateIV
   IV = aesImplementation.IV
End Sub
