I am curious to know how most Windows GUI programs have been written - for example, AOL Instant Messenger, Microsoft Word, Notepad, other popular shareware programs and more.
Thank you!
Older programs are usually written in Visual C ++, usually on structures like MFC at top. (Unless the program was written by Microsoft, which practically never used MFC. :)) Visual Basic was also very common for internal or amateur applications, but not for the famous "mainstream" ones.
New programs are usually written on the .NET platform, so in C # or VB.NET.
