Hi Sergey,

The OnAcquire event handler is declared:

void __fastcall ImageAcquired(
const unsigned DibHandle,
const Word XDpi,
const Word YDpi,
const int CallBackData);

I am sorry I have very few C++ Builder examples. This is on my todo list. Generally, going from Delphi to C++ is quite straight forward though.

Best regards,

Michel
