[Solved] Question Re: _WinAPI_CreateFile()

[DYONISII]

i am currently using:

$handle = _WinAPI_CreateFile($filename, 2, 2)
if $handle then
  ;do process here
else
  msgbox(0,"warning","file can not be opened.")
endif

however i want to know how i can open $filename even if it has been opened by another application.

the fourth argument is $iAttributes with possible values: 1=file should be archived; 2=file is hidden; 4=file is read only; 8=file is part of or used exclusively by an operating system.

using 4 for $iAttributes won't allow me to open $filename if it is already open.

any help would be appreciated.

thanks!

Well, you can try fileclose. Also take a look at fileopen. It can be used easier than _WinAPI_CreateFile(). Just a suggestion.

dantay9,

thanks for your quick reply. i can't use fileopen() because the files that i need to open may be as big as 4Gb or even larger. i am also using _WinAPI_CreateFile() in conjunction with _WinAPI_ReadFile().

further, if the file has been opened by another application, i am not allowed to close it. i just need to read from it, if it has been opened already.

rover,

thanks so much. i don't know why i totally forgot that the arguments can be added together LOL!

i tried 2, and it worked but wondered why 4 won't work. turns out 7 is the correct argument.

thanks so much.

now, my torrent maker is finally done!
