Visual Basic: Bi-Directional Programming
Bidirectional features of Windows APIs are generally implemented as additional arguments and constants for standard APIs. The collection of API text files viewable with the API Text Viewer, particularly Win32api.txt, include references to arguments and constants for bidirectional features. Proper syntax is displayed in these files that you can copy and paste into your code.
These arguments and constants can be included in Windows API calls to any version of 32-bit Microsoft Windows. However, the API calls will only perform the requested bidirectional function if the operating environment is a bidirectional version of 32-bit Microsoft Windows, such as Arabic Microsoft Windows 95.
