malu05 Posted July 28, 2008 Share Posted July 28, 2008 Hello there.Some time ago I asked this very same question but with no luck, i guess its because i called it "de-inject" enstead of "eject".I'm working on the WoW machinima Tool with a friend of mine.http://www.autoitscript.com/forum/index.php?showtopic=74509http://www.madx.dk/wmt/The other developer on this project is forming out the dll for NPC (non player character) Spawn and Animation / Movement Controls so we can make scripted film sequences in-game.To get the dll to work we inject it into the game's exe while running, and that works fine and all the functions work as intended.Now the problem is, when the user of the tool is finished using it he exits the tool but the dll is still there. So I need to figure how to eject the DLL when the app closes.For the injection I use:expandcollapse popup#include-once Func _InjectDll($a, $dllpath, $hWnd_or_pid=0) ;make sure the user passed valid parameters If $a <= 0 Then SetError(-1) Return False ElseIf StringLen($dllpath) <= 4 Or StringRight($dllpath, 4) <> ".dll" Then SetError(-2) Return False EndIf Local $pid, $pHandle, $pLibRemote, $modHandle, $LoadLibraryA, $hThread ;open dll that we'll be using Local $kernel32 = DllOpen("kernel32.dll") If $hWnd_or_pid = 0 Then ;get the pid from the window provided $pid = DllCall("user32.dll", "int", "GetWindowThreadProcessId", "hwnd", $a,"int*" , 0) If IsArray($pid) Then $pid = $pid[2] Else SetError(-3) Return False EndIf Else $pid = $a EndIf ;open the process for writing $pHandle = DllCall($kernel32, "int", "OpenProcess", "int", 0x1F0FFF, "int", 0, "int", $pid) If IsArray($pHandle) And $pHandle[0] > 0 Then $pHandle = $pHandle[0] Else SetError(-4) Return False EndIf $pLibRemote = DllCall($kernel32, "int", "VirtualAllocEx", "int", $pHandle, "short", 0, "int", 0x1000, "int", 0x1000, "int", 4) If IsArray($pLibRemote) Then If $pLibRemote[0] > 0 Then ;debug ConsoleWrite("0x" & Hex($pLibRemote[0], 8) & @CR) $pLibRemote = $pLibRemote[0] Else SetError(-5) Return False EndIf Else SetError(-6) Return False EndIf For $i = 0 To StringLen($dllpath) $ret = DllCall("kernel32.dll", "int", "WriteProcessMemory", "int", $pHandle, "int", $pLibRemote + $i, "int*", Asc(StringMid($dllpath, $i + 1, 1)), "int", 1, "int", 0) If IsArray($ret) Then If $ret[0] = 0 Then SetError(-7) Return False EndIf Else SetError(-8) Return False EndIf Next $modHandle = DllCall($kernel32, "long", "GetModuleHandle", "str", "kernel32.dll") If IsArray($modHandle) Then If $modHandle[0] > 0 Then $modHandle = $modHandle[0] ConsoleWrite($modHandle & @CRLF) Else SetError(-9) Return False EndIf Else SetError(-10) Return False EndIf $LoadLibraryA = DllCall($kernel32, "long", "GetProcAddress", "long", $modHandle, "str", "LoadLibraryA") If IsArray($LoadLibraryA) Then If $LoadLibraryA[0] > 0 Then $LoadLibraryA = $LoadLibraryA[0] ConsoleWrite($LoadLibraryA & @CRLF) Else SetError(-11) Return False EndIf Else SetError (-12) Return False EndIf $hThread = DllCall($kernel32, "int", "CreateRemoteThread", "int", $pHandle, "int", 0, "int", 0, "long", $LoadLibraryA, "long", $pLibRemote, "int", 0, "int", 0) If IsArray($hThread) Then ConsoleWrite($hThread[0] & @CR) If $hThread[0] > 0 Then $hThread = $hThread[0] Else SetError(-13) Return False EndIf Else SetError(-14) Return False EndIf DllCall($kernel32, "int", "VirtualFreeEx", "int", $pHandle, "int", $pLibRemote, "int", 0x1000, "int", 0x8000) DllCall($kernel32, "int", "CloseHandle", "int", $hThread) DllCall($kernel32, "int", "CloseHandle", "int", $pHandle) DllClose($kernel32) Return True EndFuncNow how do I revert this function and Eject the dll again?
