I converted a VB 6.0 project to .NET 2005,had some errors:
Hi!
This VB 6.0 code
aData = StrConv(strIn, vbFromUnicode)
And this how it get converted ti .NET 2005
aData = System.Text.UnicodeEncodin
This was not converted
Decode = StrConv(m_oXMLElement.node
Decode = StrConv(m_oXMLElement.node
These don't work!
What is a correct conversion in .NET to these
These are parts of this Base64 class http://www.webdictionary.fi/kuvat/Base64.zip
If it's needed as "whole picture" here
Matti
What data type is m_oXMLElement.nodetypedval

Thanks!
I'm saving email attachments in my project.
It was a bit stupid to use old VB class, The .Net had a function for it.
I'm just learning .NET I don't remember all it's namespaces.
Imports System.Convert
Dim strUnBASE64 As String
Dim strUnBASE64b() As Byte
Some code here
strUnBASE64b = Convert.FromBase64String(s
strUnBASE64 = System.Text.Encoding.Defau
And this I can save to file.
It works OK even when there are multible attacments and it was faster than this old class.
There is some for tasky to a good try

Ah, fear not, we all had to make the switch to .NET sometime. And believe it or not, I did the same thing (tried to port a VB6 class to .NET---for base64) before I decided to google an answer. By the way, welcome to the wonderful world of .NET!
