If the program is of any size, you'll get enough errors that you can open an error-selling business. But the only way to port VB6 to VB dot net is by hand. No one has written a good porting program. (Even the automatic conversion in 2003 left half the program or more to be hand-converted.)How can I convert VB6 code to VB 2008?
Copy all the code from your VB6 project and into a new VB08 Project. Then edit out any errors you get. They may/should be only a couple.
in my experience, the best way is to write from scratch. You can reuse parts of the code of course, but the change in paradigm is too big for a straight conversion.
