我的窗戶無法打開

Question

我一直在這裏5個小時信不信由你。我非常緊張，因爲它看起來很基本，當我真正掌握了所有這些資源時，讓程序變得更容易。

繼承人我的代碼：

#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; 
} 

當我點擊我的WndProc中WM_COMMAND我ID_HELP_ABOUT case語句，什麼都不會發生。它甚至沒有進入我的AboutDlgProc函數。

請幫助！ =）

更改對話框中調用這個：

DialogBox(hInstance, MAKEINTRESOURCE(DIALOG_BOX), hwnd, AboutDlgProc);
