Re: MVP, Please re: CryptoAPI / .NET Framework Interoperability

I would suggest a test using a byte array with fixed content in both VB6 and
C#. Right now you are using strings which raises all kinds of questions
about Unicode vs multibyte and which multibyte encodings might be used.
Start with some simple binary data and once that works move on to strings.

Is there an MVP in the house?

My query from October 22 remains unanswered. It relates to using VB6 and
the CryptoAPI to create an encryptor which can interoperate with the .NET
Framework's DESCryptoServiceProvider.

You are replying to a message in which the OP explained what he had done
wrong and how he fixed it, so I think it's safe to say the issue is
resolved.
Also your workaround is usually not possible, because classes can mutually
use each other and thus it's not possible to call TypeBuilder.CreateType

1. What version of .NET are you running on (specify the version of
mscorwks.dll).
2. Do you see any callstack?
3. What type of applicatin is it?
If you are running on .NET2.0 try installing .NET3.5 SP1 (which includes

I have not heard from you for several days. I am writing to check the

I am attempting to create a VB6 routine equivalent to the
DESCryptoServiceProvider in .NET 3.5. The reason is that I am trying to
encrypt info in a VB6 app, and decrypt it in a C# app. I have working
encryption/decryption routines in each (that is, encrypt/decrypt in VB6 and
encrypt/decrypt in C# both work), but the algorithms don't match (i.e. the

Don't the Forms Designers use CodeDOM to parse the InitializeComponent

these interfaces?
