I don't know if somebody else already had got this idea (I couldn't find anything similar in the forum). Anyway, I needed this functionality for another project and thought it would not hurt to share it. This neat little UDF wraps DllStructs into an AutoItObject. This not only increases comfort and simplifies syntax when handling structs but also allows use structs as property or function parameter in objects. Use it like this (more elaborate examples are attached): #include <AIOStruct.au3
