From Khaled's FAQ:
Question: In which language is mIRC written? Answer: mIRC is written in a mixture of C/C++, in pure win32 code, and compiled under Visual Studio .Net Pro. mIRC was originally developed under Borland C++ v5.02 however.
I used Borland C/C++ v5.02 because it allowed parallel development of 16/32bit code from the same code-base. This isn't important anymore because the 16bit mIRC is no longer being developed.
From the
versions.txt:
29/08/2003 - mIRC v6.1 31.Now using Visual C++ .NET 7.0 to compile mIRC.
