The integrator does not always support all the properties and methods of a particular ActiveX control. The following restrictions apply to OLE Automation event and method properties and parameters:
- Unsigned eight-byte integer parameters are not supported correctly for values over 9223372036854775807 because the Adelia NUM_BIN_8 type is a signed type.
- Signed and unsigned integer pointer parameters are not supported.
- Signed and unsigned string pointer parameters are not supported.
- Array parameters are not supported. In practice, arrays are managed using a VARIANT variable.
- Output VARIANT variables (i.e. when the value is provided by the ActiveX control) that contain an array with more than one dimension are not supported. Variants containing a one-dimensional array are converted to Adelia list variables.
- Input VARIANT variables (i.e. when the value is provided by the Visual Adelia program) are converted to one-dimensional arrays in the case of list variables. It is not possible to specify the number of dimensions in the array.
- Output VARIANT variables containing a structure (group of variables) or an array of structures are not supported.
Note that the fact that a particular event parameter is not supported does not prevent the event from occurring.
