Hi: I want porting VC++ source code to Autoit, How can set __int64 to function SetFilePointer in Autoit ?? //////////////////Autoit//////////////////////////////////// Func Read($TestDecive,$LBAPos,$Readlength) local $Result = _WinAPI_SetFilePointer($TestDecive, $LBAPos*512,0) EndFunc //////////////////Autoit//////////////////////////////////// //////////////////VC++//////////////////////////////////// BOOL Read(HANDLE dev,DWORD Sector_Start,int Sector_num) { BOOL flag; DWORD Program_len; __int64 distance = Sector_Start*0x200; LARGE_INTEGER li; li.QuadPart = distance; li.LowPart = SetFilePointer (dev, li.LowPart, &li.HighPart, FILE_BEGIN); if (li.LowPart == 0xFFFFFFFF && GetLastError() != NO_ERROR) { li.QuadPart = -1; return false; } flag = ReadFile(dev,Buffer,Sector_num*0x200,&Program_len,NULL); return flag; } //////////////////VC++//////////////////////////////////// Thanks for your answering !!

Thank you for your help !!

Hi: how can I get the pointer of offset? local $Buffer = DllStructCreate("byte[" & 0x10*512 & "]") local $ptr = DllStructGetPtr($Buffer) How can I get the pointer of byte[512]? Use DllStructGetPtr ?? Thanks for your help !!

Thanks for your help !

Hi: I try to read file data and show it on Edit,but Edit only show to length 00001780,Why? How can I show more? If I show too more data the GUI Edit will hang ? Need CoProc?? Have any Example?

Hi all: $nBytes = 1024 $hBuffer = DllStructCreate("ubyte buffer[" & $nBytes & "]") $pBuffer = DllStructGetPtr($hBuffer) . How to fill data pattern 0x55AA or any data pattern to $hBuffe not with "for"? What method is fast ?? call memset ?? Thanks for your answer
