Windows Assembly Language Programming
This area on Webster is dedicated to Win32 assembly language programming topics. Specifically, this section deals with the Win32 API, HOWL (the HLA Object Windows Library), and GUI-based programming in assembly language.
Windows Programming in Assembly Language
|Several years ago, Randy Hyde began translating Charles Peztold's "Windows Programming" into assembly language. This book teaches Win32 GUI application programming using the Win32 API. For copyright reasons, plus the fact that the material was just not the right way to write Win32 assembly code, Randy abandoned that project. However, the first several chapters are available on-line and still provide a great reference for programmers who want to write low-level Win32 code.

Randy Hyde's Windows Programming Tutorial
HOWL (HLA Object Windows Library) has arrived! HOWL makes Win32 assembly language programming easier than ever before. By providing an "Application Framework" (much like Microsoft's MFC or Borland's VCL), HOWL takes care of all the grunt work required by low-level Win32 API programming and lets you concentrate on writing your applications.
This is the right way to write Win32 GUI applications in assembly language.
Note that the tutorial source code is available as part of the HLA Examples download (get it here). If you're going to work through these tutorials, you should download the entire HLA examples zip file. You'll find the HOWL examples in the win32\howl subdirectory.
Also note that the HOWL documentation is part of the HLA Standard Library documentation. You can find the HOWL documentation here.
The example source files to the right generally appear in pairs: a "standard" version and an "x_*" version. The standard version uses the HOWL Declarative Language (HDL) to define all the widgets (controls) on a form (window). Those with the "x_" prefix eschew the HDL and make manual calls to the HOWL library code. The tutorials mainly discuss the standard versions of these sample programs; those who are interested in seeing the lower-level implementation of the code might want to take a peek at the "x_*" versions of these applications.
3: Check Boxes
4: Radio Buttons
7: Graphic Objects
This tutorial teaches you how to draw various graphic objects on a form including rectangles, round rectangles, pie wedges, ellipses and circles, and polygons.
This tutorial also teaches you how to overlay various graphic objects using a transparent background color and how to create clickable graphics objects. It demonstrates how to move, resize, show/hide, and change the color of these graphic objects.

The following are some of the reknown Iczelion win32 tutorials with their text and code updated for HLA (the original tutorials used MASM). Check back here frequently because new translations will appear on a regular basis.
