Hi,
What is Unattended Execution in DLL? I have a DLL which will communicate with hardware through serial port.
My main program will pass the reference of NOTIFY class to my DLL once it call DLL to do something with the hardware.
The NOTIFY class is responsible to load a form in class_initialise. My DLL will then call UpdateProgress() method of NOTIFY class in certain process to show the current progress.
Does this design work ok? Does unattened execution will effect my design? Is it a acceptable design for DLL?

thank you
