Hello! What arguments should be passed to these variables "unsigned int This" if you call the function with your hook manually? Did you manage to figure this out? Because when I override the existing function with my hook using an existing int, everything works fine

int __fastcall hkRequestAuthLogin(int thisPtr, void* edx, wchar_t* Login, wchar_t* Password, int OTP)
{
    mLogin = L"qwertyui";
    mPassword = L"1234567";
    mOTP = -1;
    return fpRequestAuthLogin(thisPtr, mLogin, mPassword, mOTP);
}

, but I still couldn’t manage to call the function externally.

void myLogin(wchar_t* Login, wchar_t* Password, int OTP)
{
    mLogin = Login;
    mPassword = Password;
    mOTP = OTP;
    fpRequestAuthLogin(1432, mLogin, mPassword, mOTP);
}

Can u help me with this?

It's just a number from nowhere. ) I tried to intercept these values that the client provides to the original function, and each time it's a new number, 9 digits long, like this: 163791744.

you see im from l2 interface send data to server before login via "RequestPCCafeCouponUse("your data bla bla bla"); and then hook this function in DLL:
?RequestPCCafeCouponUse@UNetworkHandler@@UAEXVFString@@@Z
int __fastcall new_RequestPCCafeCouponUse(unsigned int This, wchar_t * data) {

// extract your info from data variable... which u send from interface RequestPCCafeCouponUse

fpRequestAuthLogin(This,  L"ID",L"PASS" ,0);
return 0;
}

Oh, I hadn't thought of that, thanks for the tip! But what this ‘this’ is, I don't understand at all.

Hmm, I wonder if I can save this value and use it in the future, so that I can access specific functions without using other packages. Thank you for your answers, they are very helpful to me!
