[Programming C++] Simple Api-Hook

[DragonHunter]

Ok since maxtor still didnt made those sections cuz i dunno why... or he dont want to make those sections whatever

but anyways

 

#include <detours.h>

//Prototype of the original ShellAboutW API
int (__stdcall *ShellAboutWD_o)( HWND hWnd, LPCWSTR szApp, LPCWSTR szOtherStuff, HICON hIcon);

//Hooked ShellAboutW API
int __stdcall ShellAboutWD(HWND hWnd, LPCWSTR szApp, LPCWSTR szOtherStuff, HICON hIcon)
{
        return ShellAboutWD_o(hWnd, L"DragonHunter [LeetCoders]", L"The about API/Function is hooked by DragonHunter ;D!", hIcon); //Return to original api function
}

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        HANDLE ShellAboutWDProcessAddress; //Hold the ShellAboutW API memory address

        ShellAboutWDProcessAddress    =  GetProcAddress(
                                                        GetModuleHandle(L"Shell32"), //DLL Library
                                                        "ShellAboutW"                 //API/Function
                                                      );
        //Since we now have the memory address of ShellAboutW we can finally start the hook process :)


        if(ShellAboutWDProcessAddress != 0) //Check if memory address is found (Error-Handling)
        {
            ShellAboutWD_o = (            //Set the original API/Function
                int (__stdcall *)(        //Prototype
                HWND hWnd, LPCWSTR szApp, LPCWSTR szOtherStuff, HICON hIcon)) //Prototype
                DetourFunction(                        //Api-Hook ShellAboutW
                (PBYTE)ShellAboutWDProcessAddress,    //Get memory address
                (PBYTE)ShellAboutWD);                //Set ShellAboutWD_o -> ShellAboutWD
        }
        break;
    case DLL_PROCESS_DETACH:
            if(ShellAboutWDProcessAddress != 0)
            {
                DetourRemove(
                    (PBYTE)ShellAboutWDProcessAddress,    //Unhook the API/Function
                    (PBYTE)ShellAboutWD);
            }
        break;
    }
    return TRUE;
}

 

And this is the output

 

Have fun...

i think a section like that would be nice indeed, tho you have dozens of forums dedicated to it.. like you can find the code above with a quick google search..
