Creating a Win32 DLL and a Program to Test the DLL
This is the beginning of a series of articles about using RosAsm to create Win32 programs. Each article shall be presented in a step-by-step illustrated style with some comments.

RosAsm, the Bottom-Up Assembler for ReactOS also for WINE, Windows 95/98, NT/2000, XP. RosAsm is free and GPLed.

IDE with full integration of all components. RosAsm is auto-compilable and the Sources are hosted inside the PEs. No installation overhead (the silent auto-install coming with RosAsmFull.zip makes RosAsm the only actual Click&Go Assembler environment).

Real Sources Editor with tons of unique features, specificaly devoted to secure editions and to huge mono-files assembly sources: Tree-view, instant jump to any type of declaration by simple right-click, division of the mono-files into TITLEs, advanced IncIncluder pre-parser, and so on...

The fastest of the actual assemblers, (1.5 Mega/second on a Celeron 1.3 Ghz...) directly outputting PE files on a simple click, with a powerful macros Système (a macros unfolder is available by a double-click, through a float menu). Simplified Intel syntax. Does not need any include, prototype or header companion file. Nothing but a single simple source. Complete implementation of the mnemonics set, up to SSE2. RosAsm Bottom-Up Assembler is a true low level Assembler, enabling HLL writing styles by user defined macros and/or by HLL pre-parsers selections.
