Dll in GUI

  • Dll in GUI

    Hallo Community,

    nachdem mein Problem mit der GUI gelößt wurde, habe ich nun eine einwandfrei funktionierende hübsche Oberfläche: :)

    C-Quellcode

    1. #include <windows.h>
    2. #include <stdio.h>
    3. #include <cstdio>
    5. #ifdef _UNICODE
    6. #if defined _M_IX86

    8. #elif defined _M_X64

    In dem rot gekennzeichneten Bereich, lese ich einen Wert aus einem Edit Feld aus und speichere diesen in der Variable "text".

    Nun habe ich eine weitere Datei: Eine Dll.

    C-Quellcode

    1. #include <iostream>
    2. #include <windows.h>
    3. #include <detours.h>
    5. BOOL WINAPI DllMain(HINSTANCE hinstDll, DWORD Reason, LPVOID Reserved)
    6. {
    7. switch(Reason)
    8. {
    9. case DLL_PROCESS_ATTACH:
    10. MessageBox(0,L"Attached.",L"Info",0);
    12. break;
    13. case DLL_PROCESS_DETACH:
    14. MessageBox(0,L"Detached.",L"Info",0);
    15. break;
    16. }
    17. return TRUE;
    18. }
