Remember that the Win32 API is not specific to VB.NET but rather a lower-level interface for Windows programming in general. Therefore, some examples and resources you find may be in C/C++. However, you can easily translate the code and concepts to VB.NET.
It's worth noting that there are higher-level frameworks and libraries available for Windows development that abstract away the need to directly work with the Win32 API, such as Windows Forms or WPF. These frameworks provide a more streamlined and VB.NET-friendly approach to building Windows applications.
