Squeeto Posted February 12, 2009 Share Posted February 12, 2009 Hi guys, I have been troubled with this one a while; it is time to ask. I would like to delete a file after a DllCall for CreateFile but the call holds up the file. Am I not releasing it somehow? #include <GUIConstants.au3> $main = GUICreate("", 115, 65) $btn = GUICtrlCreateButton("", 20, 20, 75, 25, $BS_DEFPUSHBUTTON) GUISetState(@SW_SHOW) While 1 $msg = GUIGetMsg(1) Select Case $msg[0] = $GUI_EVENT_CLOSE And $msg[1] = $main ExitLoop Case $msg[0] = $btn And $msg[1] = $main $s = @ScriptDir & "\asdf.txt" a($s) FileDelete($s) ;<---why doesn't this work? EndSelect WEnd Func a($file) $hFile = DllCall("kernel32.dll", "ptr", "CreateFile", _ "str", $file, _ "dword", $GENERIC_READ, _ "dword", $FILE_SHARE_READ, _ "dword", "", _ "dword", $OPEN_EXISTING, _ "dword", $FILE_ATTRIBUTE_NORMAL, _ "ptr", 0) If Not @error Then ;... I will do more here later DllCall("kernel32.dll", "int", "CloseHandle", "ptr", $hFile) If Not @error=0 Then MsgBox(0,"Error",@error) Else MsgBox(16, "Error", "Error retreaving file.") EndIf EndFunc TIA Link to comment Share on other sites More sharing options...
monoceres Posted February 12, 2009 Share Posted February 12, 2009 Both CreateFile and CloseHandle are available in WinAPI.au3 as _WinAPI_CreateFile and _WinAPI_CloseHandle, so you don't need to worry about the calling of the functions. Broken link? PM me and I'll send you the file! Link to comment Share on other sites More sharing options...
Authenticity Posted February 12, 2009 Share Posted February 12, 2009 Read again DllCall documentation and what kind of variable it returns ^^ Link to comment Share on other sites More sharing options...
