You would have a variable that could hold integer values from -32,768 to 32,767. You added the following variable declaration in Visual Basic: Dim intCount as Integer Most of the data types are very similar overall, but not exactly the same. If you’ve ever programmed in languages other than Basic, you’ve probably noticed that In this chapter we’ll build the UI for this project as well as covering how the encryption algorithm will function although we’ll leave the coding for the next chapter. We will use this application throughout the rest of this book as a test ground for our Win32 development. This will allow you to avoid some of the classic problems that have tripped up many other VB programmers in the past.įinally, we’ll be introduced to the Encryption Program. In this chapter we’ll be investigating how API calls work at a much lower level. So you should now be ready to get down to some of the real nitty-gritty.

In the previous chapter, we looked at the basics of an API call and went over someĮxamples of how to use them in VB.
