Joe Posted October 27, 2008 Share Posted October 27, 2008 Hi, I want to use DLL functions in my script, but can't get it to work. I've tried DllCall, but nothing happens. This is the code in C# using System; using System.Runtime.InteropServices; namespace ConsoleApplication1 { class Program { [DllImport("packet.dll")] private static extern bool SendPacket(uint processID, byte[] packet); static void Main(string[] args) { new TestSendPacket(); } public class TestSendPacket { public byte[] packet; public TestSendPacket() { packet = new byte[3]; packet[0] = 0x01; packet[1] = 0x00; packet[2] = 0x65; SendPacket(3136, packet); } } VB Code Private Declare Sub SendPacket Lib "packet.dll" (ByVal ProcessID As Long, ByRef Packet As Byte) Private Sub Command1_Click() Dim ProcessID As Long Dim PacketBuffer(2) As Byte GetWindowThreadProcessId FindWindow("tibiaclient", vbNullString), ProcessID PacketBuffer(0) = &H10 PacketBuffer(1) = &H0 PacketBuffer(2) = &H65 SendPacket ProcessID, PacketBuffer(0) End Sub This is how my Autoit Script looks like: Global $packet[3] $packet[0]=0x01 $packet[1]=0x00 $packet[2]=0x65 $ProcessId = WinGetProcess("[CLASS:TibiaClient]") DllCall('packet.dll', '', 'SendPacket', 'long', $ProcessId, 'byte', $Packet) When I launch the script nothing happens. If I don't leave the returntype blank the script crash. I would be really grateful if someone could help me. Link to comment Share on other sites More sharing options...
Moderators SmOke_N Posted October 27, 2008 Moderators Share Posted October 27, 2008 DllCall('packet.dll', 'none:cdecl', 'SendPacket', 'long', $ProcessId, 'byte', $Packet) Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer. Link to comment Share on other sites More sharing options...
Joe Posted October 27, 2008 Author Share Posted October 27, 2008 Did not work, Autoit crash. But thanks for trying. Maybe there is no way to make it work? I've tried all different return types from the help file, they all made autoit crash. Link to comment Share on other sites More sharing options...
monoceres Posted October 27, 2008 Share Posted October 27, 2008 Try this: Local $ProcessId $bytearr=DllStructCreate("byte[3];") DllStructSetData($bytearr,1,0x01,1) DllStructSetData($bytearr,1,0x00,2) DllStructSetData($bytearr,1,0x65,3) DllCall("packet.dll","int:cdecl","SendPacket","long",$ProcessId,"ptr",DllStructGetPtr($bytearr)) If it still crashes, remove :cdecl. Broken link? PM me and I'll send you the file! Link to comment Share on other sites More sharing options...
ProgAndy Posted October 27, 2008 Share Posted October 27, 2008 Well, why don't you use wpcap.dll? possibly your packet.dll has another function call as described here. http://www.winpcap.org/pipermail/winpcap-u...ust/000243.html (it*s from 2005, but i think, this is still true) *GERMAN* [note: you are not allowed to remove author / modified info from my UDFs]My UDFs:[_SetImageBinaryToCtrl] [_TaskDialog] [AutoItObject] [Animated GIF (GDI+)] [ClipPut for Image] [FreeImage] [GDI32 UDFs] [GDIPlus Progressbar] [Hotkey-Selector] [Multiline Inputbox] [MySQL without ODBC] [RichEdit UDFs] [SpeechAPI Example] [WinHTTP]UDFs included in AutoIt: FTP_Ex (as FTPEx), _WinAPI_SetLayeredWindowAttributes Link to comment Share on other sites More sharing options...
Joe Posted October 27, 2008 Author Share Posted October 27, 2008 Try this: Local $ProcessId $bytearr=DllStructCreate("byte[3];") DllStructSetData($bytearr,1,0x01,1) DllStructSetData($bytearr,1,0x00,2) DllStructSetData($bytearr,1,0x65,3) DllCall("packet.dll","int:cdecl","SendPacket","long",$ProcessId,"ptr",DllStructGetPtr($bytearr)) If it still crashes, remove :cdecl. It worked! I only had to remove :cdecl. I would never have figured out that myself, you are the best. Thank you very much! Link to comment Share on other sites More sharing options...
