Some important differences between the ADS API in Visual Objects and the ADS API in X#
Handles In Visual Objects the handles (Table Handle, Index Handle, Connection Handle etc) are declared as DWORD. In X# they are declared as IntPtr since the size can be 32 bits when the application is running in 32 bit mode but 64 bits when the application is running in 64 bits mode.
String parameters In Visual Objects the string parameters are all declared as PSZ. In X# you can use normal strings. The .Net runtime takes care of the conversions between managed unicode strings and unmanaged native Ansi strings.
