fopen is not a standard WINAPI call, so that you must call it as like:
typedef FILE* (*fopen_Type)( const char *filename, const char *mode );
FILE* Myfopen( const char *filename, const char *mode );
FILE* Myfopen( const char *filename, const char *mode )
{
MessageBox(NULL,filename,"fopen",MB_OK);//Already get the message
//fopen_Type *OldFn=(fopen_Type*)D3DHook.Functions[0].OrigFn;
fopen_Type OldFn=(fopen_Type)D3DHook.Functions[0].OrigFn;
return OldFn(filename,mode); //compiler is ok but error in here when hook
}
Why are you use Hook Api? Only to trace the exe's call?
Why didn't use this tool "Auto Debug Tool"?

This is exactly what I was looking for. I think it's pretty funny the source code shows you were reverse engineering EverQuest though .

I just downloaded your source code. But i found out that the dll was infected by PWS-Sincom.dll virus. I'm using Network Associates VirusScan.

Neither freeav (www.freeav.com) or HouseCall (housecall.antivirus.com) showed there being a virus in these files for what it's worth.

Just rename the DLL and the f#%$ stupid antivirus wont see it as one

//"WSOCK32.DLL",
false, NULL, // Default hook disabled, NULL function pointer.
{
{ "send",hooksend },
{ "recv",hookrecv },

{ NULL, NULL }
}
};
then
if ( stricmp( Work, "Iexplore.exe" ) == 0 )

Hello, I would like to upload my dll(a.dll) into a program(a.exe). How would I go about doing this?
|
|
|
|
|
Is there a way to unhook hooked api calls (by apihijack) to avoid crashing hooked programs when the general hooker program is closed?
Something like returning original pointers to their place?

I'm trying to find a handle leak by hooking several of the Kernel32 api functions that create handles like CreateEvent, CreateFile, and CreateThread.
When I hooked CreateEvent, I started having problems with crashes in some of our libraries. I noticed that one of the libraries was compiled with optimization (for speed) turned on. When I turn off the optimization, the problem went away. I'm still having problems with another library that I don't have source for, and I suspect a similar problem.
Any ideas why hooking CreateEvent is causing a problem? Any idea why the optimzer would make the problem worse?
Thanks,
Larry M.

In VB we can call a function from C++ dll using "Declare".
Declare function Test Lib "MyFileName.dll" Alias "TestA" (ByVal nVal As Long)
Is it possible to supply the dll filename at runtime ?
|
|
|
|
|

APIs are redirected but never restored! If I close TestLauncher app before hooked application, it crashed when calling hooked function, because function entry points are not valid when dll is unloaded.

Hi,
as I understand this code catches only the dlls which are linked to the "exe"(even if they are delay loaded).. And the original microsoft sample seems to do the same. But is there a way to catch "LoadLibrary" call which is produced by "exe" to any dll? I mean what if I create a dll, say test.dll, and then somewhere in my code I write
LoadLibrary("test.dll"). Is there a way to redirect all functions from this library to my own ones in the same manner it is done for preloaded dlls?
Thanks for any help
Alex

Hi,
So, I have coded ApiHiJack to hook the GetDeviceData(....) but this code don't work.
When I hook the function CreateDevice it works.
How I could hook a method ?
|
|
|
|
|
So, I have found a ancien post and I found a part of code, but when I write this line :
IDirectInputVtbl OldIDirectInputVtbl;
I have 3 errors :
D:\Dev\Hook_Direct_Input\Hook_GetDeviceData\TestDLL\dllmain.cpp(12) : error C2146: syntax error : missing ';' before identifier 'OldIDirectInputVtbl'
D:\Dev\Hook_Direct_Input\Hook_GetDeviceData\TestDLL\dllmain.cpp(12) : error C2501: 'IDirectInputAVtbl' : missing storage-class or type specifiers
D:\Dev\Hook_Direct_Input\Hook_GetDeviceData\TestDLL\dllmain.cpp(12) : fatal error C1004: unexpected end of file found
And I don't know how I can do ???????
|
|
|
|
|
So I juste forgot #define CINTERFACE.
know I haven't errors.
But I have a question :
If I want to intercept GetDeviceData()
I need configure ApiHiJack to Hook CreateDevice ?
And after I put the part of code to hook the new method ?
@+
P.S. : ApiHiJack is very useful and have more & more possibilities.
It's very interesting.
Great Software !

I just see I have a big problem :
This is the action to perform a getdevice data :
run function DirectInput8Create(...) :
This function create a DirectInput8 object
This object containt method CreateDevice(....)
Run method CreateDevice(...)
This function create a DirectInputDevice8 object
and this object contain method GetDeviceData(...)
So how I could hook the GetDeviceData(...) ?????
Need I to hook each function & method ?

Is anybody help me modify the ApiHijack project let me hijack the directdraw's
"drawtext" function?
for example, if DX Game call DrawText to show "Hello",, My program can change
the text to "Aloha"
many many many thanks!
|
|
|
|
|
You could do it with standard DirectDraw methods, but I doubt many games really use DrawText. Most use their own text drawing routines that create polygons from a texture map.
