Hi,
Can anyone help me fix this. I try to create an ahk program that can send packet to server in HEX. I already create half of the code by referring client/server guide in the forum but still failed. It already connect to the server but not sending HEX packet.
Thank you

connect()
{
; Network address & port
Network_Address = 35.23.13.234
Network_Port = 3874
; Connect to server:
socket := ConnectToAddress(Network_Address, Network_Port)
if socket = -1 ; Connection failed (it already displayed the reason).
ExitApp
NotificationMsg = 0x5555 ; An arbitrary message number, but should be greater than 0x1000.
OnMessage(NotificationMsg, "ReceiveData")
FD_READ = 1 ; Received when data is available to be read.
FD_CLOSE = 32 ; Received when connection has been closed.
if DllCall("Ws2_32\WSAAsyncSelect", "UInt", socket, "UInt", ScriptMainWindowId, "UInt", NotificationMsg, "Int", FD_READ|FD_CLOSE)
{
MsgBox % "WSAAsyncSelect() indicated Winsock error " . DllCall("Ws2_32\WSAGetLastError")
ExitApp
}
return
}
ConnectToAddress(IPAddress, Port)
{
VarSetCapacity(wsaData, 32)
result := DllCall("Ws2_32\WSAStartup", "UShort", 0x0002, "UInt", &wsaData) ; Request Winsock 2.0 (0x0002)
if ErrorLevel
{
MsgBox WSAStartup() could not be called due to error %ErrorLevel%. Winsock 2.0 or higher is required.
return -1
}
if result
{
MsgBox % "WSAStartup() indicated Winsock error " . DllCall("Ws2_32\WSAGetLastError")
return -1
}
AF_INET = 2
SOCK_STREAM = 1
IPPROTO_TCP = 6
socket := DllCall("Ws2_32\socket", "Int", AF_INET, "Int", SOCK_STREAM, "Int", IPPROTO_TCP)
if socket = -1
{
MsgBox % "socket() indicated Winsock error " . DllCall("Ws2_32\WSAGetLastError")
return -1
}
; Prepare for connection:
SizeOfSocketAddress = 16
VarSetCapacity(SocketAddress, SizeOfSocketAddress)
InsertInteger(2, SocketAddress, 0, AF_INET) ; sin_family
InsertInteger(DllCall("Ws2_32\htons", "UShort", Port), SocketAddress, 2, 2) ; sin_port

return -1
}
;connection success
return socket
SendHex := A7006337003054D0 ;send packet in hex
SendData(socket,SendHex) ;passing val
}
SendData(wParam,SendData)
{
socket := wParam
;MsgBox %socket% %SendData%
SendDataSize := VarSetCapacity(SendData)
SendDataSize += 1
sendret := DllCall("Ws2_32\send", "UInt", socket, "UInt", 0x0008h, "Hex", SendData, "Int", SendDatasize, "Int", 0)
}
InsertInteger(pInteger, ByRef pDest, pOffset = 0, pSize = 4)
{
Loop %pSize%
DllCall("RtlFillMemory", "UInt", &pDest + pOffset + A_Index-1, "UInt", 1, "UChar", pInteger >> 8*(A_Index-1) & 0xFF)
