Need help on DllCallAddress

[HoangTieuBao]

First, I really want to know what API is DllCallAddress used?

Second, I have this code

#include <Winapi.au3>

$SOCKETID = _GetSocketId()
$hModule = _WinAPI_GetModuleHandle("Ws2_32.dll")
$pProc = _WinAPI_GetProcAddress($hModule, "send")

$pBuffer = DllStructCreate("byte[5]")
DllStructSetData($pBuffer, 1, Binary("0x2EE96B457B"))

$ret = DllCallAddress("int", $pProc, "dword", $SOCKETID, "ptr", DllStructGetPtr($pBuffer), "int", DllStructGetSize($pBuffer), "int", Null)

Then, I get @error = 1 (not have in help document) and $ret = ""

So, anybody help me about this problem, I'll thks that person

@error  is set to non zero if the call fails and 1 is non zero so I think the help covers it.

Have you checked that GetModuleHandle and GetProcAddress are returning sensible answers?

Have you tried using DllCall?

I know @error is set to non zero if the call fails, but @error = 1 isn't had in the help

This is in the help

 

Success: an array. See remarks. Failure: sets the @error flag to non-zero. @error: 2 = unknown "return type",

4 = bad number of parameters,

5 = bad parameter

 

Don't have @error = 1

And GetModuleHandle and GetProcAddress are returning successful, (exactly value)

But DllCallAddress still fails.

I tried DllCall, it isn't what i need, it fails too

The code from the first post can't succeed for sure. You see, you got the dll name wrong (superfluous space character).

I'm sure about the first post. The dll name is exactly.

This is link about function: http://msdn.microsoft.com/en-us/library/windows/desktop/ms740149%28v=vs.85%29.aspx

And one more thing, I tested code, it works ok, no problem about ProcAddress and ModuleHandle

She's telling you there's a space after the file name in your first post.

oh, right :v Because I write the code by manual when post.. Sr !!!

But in the real code, I tested it. DllCallAddress set @error = 1, this is reason that I don't understand

Well, one thing I see is that you're using "$SOCKETID = _GetSocketId(") but then using "$ret = DllCallAddress("int", $pProc, "dword", $SOCKET, "ptr", DllStructGetPtr($pBuffer), "int", DllStructGetSize($pBuffer), "int", Null)". Perhaps that is part of your problem, wrong variable name?

Oh, tks for remind.

And then, I check my code again.

But it still fails ^^~

I think DllCallAddress function which still is not performance to use

Show your exact code. Why are you showing some code you don't run?
