(Question) Conditional detour return method about blackbone HOT 8 OPEN

Sadly this is impossible without modifying detour source itself. I'll probably redisign it a bit, shortly.

Alright, no worries.

Another thought - if there was some method like Detour.Original(...) then this would allow us to execute our both before and after which is pretty useful.

Cheers!

You could potentially copy over the last few bytes by including a function that searches through the function for 0xC3 (RET) and other wanted bytes for "return x;". It would look something like->

void *retloc = SaveReturn(function, detour);

I could try to make it if you're too busy DarthTon (though I suck at git in general ._. ).

Yeah, pull request will be nice.

Can you not Returntype::new remove detour call original save result reapply detour and then return your value or the new value depending on criteria?

I think current version support it already. My example code is working:

#define BLACKBONE_STATIC
#include <LocalHook/LocalHook.hpp>
#pragma comment(lib,"BlackBone.lib")

blackbone::Detour<decltype(&MessageBoxA)> det;

int WINAPI myMessageBoxA(
In_opt HWND & hWnd,
In_opt LPCSTR & lpText,
In_opt LPCSTR & lpCaption,
In UINT & uType)
{
return det.CallOriginal((HWND&&)hWnd, (LPCSTR&&)"Test", (LPCSTR&&)lpCaption, (UINT&&)uType);
return 0;
}

int _tmain(int argc, _TCHAR* argv[])
{
decltype(&MessageBoxA) orgaddr = (decltype(&MessageBoxA))GetProcAddress(GetModuleHandleA("user32.dll"), "MessageBoxA");
bool tmp = det.Hook(orgaddr, &myMessageBoxA, blackbone::HookType::HWBP,blackbone::CallOrder::NoOriginal,blackbone::ReturnMethod::UseNew);

MessageBoxA(0, 0, 0, 0);

det.Restore();

return 0;
}
