When clicking button, it triggers an action but when I click on the "About" or "Exit" buttons it does execute the same action

My problem is when you press a menu item, which is handled by this block: 

 int wmId = LOWORD(wParam);

        // Parse the menu selections:

        switch (wmId)

        {

        case IDM_ABOUT:

            DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);

            break;

        case IDM_EXIT:

            DestroyWindow(hWnd);

            break;

        default:

            return DefWindowProc(hWnd, message, wParam, lParam);

        }

    }

        break;

It executes this block:

    switch (message)

    {

    case WM_COMMAND:

    {

        if (HIWORD(wParam) == BN_CLICKED) {

            GetWindowTextA(hWndEdit, &fin[0], 64300);

            GetWindowTextA(hWndEdit2, &scin[0], 64300);

            if (scin == (LPSTR)"") {

                ShellExecuteA(NULL, "runas", &fin[0], NULL, NULL, SW_SHOWNORMAL);

            }

            else {

                ShellExecuteA(NULL, "runas", &fin[0], &scin[0], NULL, SW_SHOWNORMAL);

            }

            if (GetLastError() != 0) {

                int i{};

                char hexstr[_MAX_U64TOSTR_BASE2_COUNT];

                int mx;

                LPSTR messageBuffer = (LPSTR)"";

                size_t size = FormatMessageA(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,

                    NULL, GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), messageBuffer, 0, NULL);



                std::string message(messageBuffer, size);

                _itoa_s((int)GetLastError(), hexstr, _countof(hexstr), 16);

                _TASKDIALOGCONFIG tdc = { sizeof(_TASKDIALOGCONFIG) };

                TASKDIALOG_BUTTON buttons[] = {

             { 1000, L"&Accept" },

             { 1001, L"&Close" }

                };

                LPCWSTR wndTitle = szTitle;

                LPCWSTR szHeader = szTitle + (WCHAR)"encountered a fatal error";

                LPCWSTR szBodyText = (LPCWSTR)"An error has occured, verify input to make sure it's correct";

                tdc.pszExpandedInformation = (PCWSTR)"Code: \n" + (WCHAR)"0x" + (WCHAR)hexstr + (WCHAR)"\n Description: " + (WCHAR)message.c_str();

                tdc.pszMainIcon = (PCWSTR)"IDI_ASTRICK";

                tdc.hwndParent = hWnd;

                tdc.dwFlags = TDF_CAN_BE_MINIMIZED | TDF_EXPAND_FOOTER_AREA | TDF_USE_HICON_MAIN | TDF_SIZE_TO_CONTENT;

                tdc.cButtons = 2;

                tdc.pButtons = buttons;

                tdc.pszWindowTitle = wndTitle;

                tdc.pszMainInstruction = szHeader;

                tdc.pszContent = szBodyText;

            }



        }

This app runs an app as adminsitator, so it executes that code when I press About or Exit, too.

How I prevent this action and make the button action only execute when the button is clicked and not anything else?
