hi all: We are developing device driver via AGDI. In Disassembly Window,when pressing the button in the scroll box and dragging, it will call ReadCode() to read all the Code from the beginning address to the ending address. It will cost a lot of time for slow device through serialport. I think it will be better to read Code in the first page at the beginning address and the last page at the ending address. The operation to read the Code bewteen the two page can be ignored. My question is: How can i read Code only in the first and last page in Disassembly Window when dragging its scroll bar?
