jaberwacky Posted October 8, 2010 Share Posted October 8, 2010 (edited) I searched the forums first but I found limited information concerning _WinAPI_CreateFileEx(). What's the difference between that and this one: _WinAPI_CreateFile()? There must be some difference between the two. If I feed them both the same arguments _WinAPI_CreateFile() will not work while _WinAPI_CreateFileEx() does work. Local Const $FileName = $DevicePath ; Ex: G:\\ Local Const $DesiredAccess = $GENERIC_READ Local Const $ShareMode = BitOR($FILE_SHARE_READ, $FILE_SHARE_WRITE) Local Const $SecurityAttributes = 0 Local Const $CreationDisposition = $OPEN_EXISTING Local Const $FlagsAndAttributes = BitOR($FILE_FLAG_BACKUP_SEMANTICS, $FILE_ATTRIBUTE_NORMAL) Local Const $TemplateFile = 0 Local Const $DevHandle1 = _WinAPI_CreateFileEx($FileName, $CreationDisposition, $DesiredAccess, $ShareMode, $FlagsAndAttributes, $SecurityAttributes, $TemplateFile) Local Const $DevHandle2 = _WinAPI_CreateFile($FileName, $CreationDisposition, $DesiredAccess, $ShareMode, $FlagsAndAttributes, $SecurityAttributes) (WinAPIEx.au3) DllCall('kernel32.dll', 'ptr', 'CreateFileW', 'wstr', $sFile, 'dword', $iAccess, 'dword', $iShare, 'ptr', DllStructGetPtr($tSecurity), 'dword', $iCreation, 'dword', $iFlagsAndAttributes, 'ptr', $hTemplate) (WinAPI.au3) DllCall("kernel32.dll", "handle", "CreateFileW", "wstr", $sFileName, "dword", $iDA, "dword", $iSM, "ptr", $pSecurity, "dword", $iCD, "dword", $iFA, "ptr", 0) I can see that there different types but they are essentially the same. WinAPI_CreateFile() works in other cases. Ok, I'm probably going to add to this post a few thousand times, so if you're interested in this then keep checking back.

Yashied Posted October 8, 2010 Share Posted October 8, 2010 For example, how do you set FILE_FLAG_WRITE_THROUGH or other FILLE_FLAG_* flags by using _WinAPI_CreateFile()? Unlike _WinAPI_CreateFile(), _WinAPI_CreateFileEx() works directly with WinAPI constants. Therein lies the difference.

jaberwacky Posted October 8, 2010 Author Share Posted October 8, 2010 (edited) The mouse runs underneath the cats nose. Thanks for pointing that out for me, Yashied. I have been confused about that for quite a while.
