The API Generator is an advanced API Viewer that lets you to create prototypesfor any VB API calls. If you have used the Microsoft API Viewer in VB6, and you are starting to work with VB. NET, the API Generator will help you to apply all your knowledge of Win API in the new environment.

I suppose, that you remember the manual extracting of the arguments and return values of the Win API functions by Microsoft API Viewer. Now you no longer need these routine procedures. Just run the API Generator, that generates all these dependencies automatically.
