    Re: Hook on an API Call

    Lyric8,

    Its system wide.
    It hooks the MessageBoxA from User32.dll.
    It wont work with the msgbox from a vb created exe because the exe is linked with MSVBVM60.DLL not directly linked with USER32.DLL.
    Also it wont work with a declared api, because still the exe only links with MSVBVM60.DLL which handles the api call.
    It should be possible to go down into the MSVBVM60.DLL and hook it there. That would be a bit more difficult and would probably have unwanted side effects. It would be hooked for any app using MSVBVM60.DLL.
