信じられないかもしれませんが、私はこれに5時間も費やしました。とても基本的なことのように思えて、とてもストレスを感じています。実際にこれらすべてのリソースを手に入れると、プログラムの作成がずっと簡単になります。

私のコードは次のとおりです。

#include <windows.h>
#include "resource.h"

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);
BOOL CALLBACK AboutDlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam );

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
                    PSTR lpszCmdParam, int nCmdShow)
     {
     static char szAppName[] = "ErrorSample";
     HWND           hwnd;
     MSG            msg;    // Look how this struct is defined-see help/class notes NOW
     WNDCLASSEX     wndclass; 
     HWND           hwndDialogBox = NULL;
     HMENU  hMenu;

          wndclass.cbSize        = sizeof(wndclass);
          wndclass.style         = CS_HREDRAW | CS_VREDRAW;
          wndclass.lpfnWndProc   = WndProc;
          wndclass.cbClsExtra    = 0;
          wndclass.cbWndExtra    = 0;
          wndclass.hInstance     = hInstance;
          wndclass.hIcon         = LoadIcon (NULL, IDC_ICON);

          wndclass.hCursor       = LoadCursor (NULL, IDC_ARROW);
          wndclass.hbrBackground = static_cast<HBRUSH>(GetStockObject (WHITE_BRUSH));
          wndclass.lpszMenuName  = NULL;
          wndclass.lpszClassName = szAppName;
          wndclass.hIconSm       = LoadIcon(NULL, MAKEINTRESOURCE(IDI_ERROR));

          RegisterClassEx (&wndclass);

          hMenu = LoadMenu(hInstance, MAKEINTRESOURCE(102));

     hwnd = CreateWindow (szAppName,         // window class name
                    "Trying my damndest",            // window caption
                    WS_OVERLAPPEDWINDOW,     // window style
                    CW_USEDEFAULT,           // initial x position
                    CW_USEDEFAULT,           // initial y position
                    CW_USEDEFAULT,           // initial x size
                    CW_USEDEFAULT,           // initial y size
                    NULL,                    // parent window handle
                    hMenu,                    // window menu handle
                    hInstance,               // program instance handle
                    NULL);                   // creation parameters


     ShowWindow (hwnd, nCmdShow);
     UpdateWindow (hwnd);

     while (GetMessage (&msg, NULL, 0, 0))
          {
          TranslateMessage (&msg);
          DispatchMessage (&msg);
          }
     return (int) msg.wParam;
     }

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, 
                          WPARAM wParam, LPARAM lParam)
     {
     static HINSTANCE    hInstance;

     switch (message)
         {

         case WM_CREATE:
             hInstance = ((LPCREATESTRUCT) lParam) ->hInstance;
             return 0;

         case WM_COMMAND:
             switch(LOWORD(wParam))
             {
             case ID_HELP_ABOUT:
                 DialogBox( hInstance, "AboutBox", hwnd, AboutDlgProc);
                 break;
             }

             return 0;

         case WM_DESTROY:
             PostQuitMessage(0);
             return 0;
         }

     return DefWindowProc (hwnd, message, wParam, lParam);
     }

BOOL CALLBACK AboutDlgProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch(message)
    {
    case WM_INITDIALOG:
        return TRUE;

    case WM_COMMAND:
        switch(LOWORD(wParam))
        {
        case IDOK:
        case IDCANCEL:
            EndDialog(hDlg, 0);
            return TRUE;
        }
        break;
    }
    return FALSE;
}

WndProc の WM_COMMAND で ID_HELP_ABOUT ケース ステートメントをクリックしても、何も起こりません。私のAboutDlgProc関数にも入りません。
