- API Vision Lite release notes
- ----------------------------------------
-
- API Vision spies on Windows API calls made by 16-bit programs
- running under Windows 3.1 and Windows 95. You can use it to spy
- on any program, wheter or not you have the source code. For each
- API call, the complete parameters are displayed, with everything
- decoded back to the names in the Windows SDK help files.
-
- Please register your copy of API Vision Lite! People who register will
- receive the file needed to spy on the important Common Dialog API's, as
- well as information on the 32-bit version of API Vision. See the Getting
- Started help file for registration information.
-
- The Getting Started help file also contains a short introduction to the
- program as well as information on ordering the full 16-bit version.
-
-
- GENERAL
- ========
-
- 1. The RegisterWindowsMessage API does not appear in the API window. This is
- because it is actually an alias to RegisterClipboardFormat - they are the
- same call with different names. Spy on RegisterClipboardFormat to see
- messages AND clipboard formats being registered.
-
- 2. Under Windows 95, certain API's, such as GetDC, don't display a return value.
- What is happening is that GetDC calls GetDCEx, which then returns directly to
- the caller of GetDC instead of returning to GetDC itself. The thing to do is
- spy on GetDCEx along with GetDC to see the complete API intercept. This sort
- of situation also occurs with the following API's:
-
- AppendMenu --> spy on InsertMenu
- AdjustWindowRect --> AdjustWindowRectEx
- DialogBox --> DialogBoxIndirect
- GetWindow --> GetNextWindow
-
- 3. If you select too many API's, the system can slow to a crawl and you may
- not be able to access API Vision to stop interception. Learn to use the
- hotkey - it stops interception from anywhere except DOS boxes. The hotkey
- setting is displayed on the status bar as a reminder.
-
-
- COPYING FILES FROM THE INSTALLATION DISKS
- ==========================================
-
- The API Vision files on the installation disks are compressed. These files
- end with a dollar sign. To copy a file manually, use the EXTRACT.EXE program
- located in your API Vision installation directory. For example,
-
- EXTRACT /U VISION.EX$
-
- The OLE files and TOOLHELP.DLL are compressed using Microsoft COMPRESS.EXE,
- and must be expanded using Microsoft's EXPAND.EXE. These files end with an
- underscore.
