c - winapi c - 添加图像的任何简单方法？

Question

我是普通 winapi c 的新手，想知道是否有任何简单的方法可以将图像添加到我的 GUI，如果可能的话，我希望这个图像基本上成为代码的一部分，这样我只需要发送单个可执行文件向其他人发送 GUI 时的文件。

#include <windows.h>

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
HBITMAP g_hbmBall = NULL;
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
    PWSTR pCmdLine, int nCmdShow)
{
  MSG  msg;    
  HWND hwnd;
  WNDCLASSW wc;

  wc.style         = CS_HREDRAW | CS_VREDRAW;
  wc.cbClsExtra    = 0;
  wc.cbWndExtra    = 0;
  wc.lpszClassName = L"Window";
  wc.hInstance     = hInstance;
  wc.hbrBackground = GetSysColorBrush(COLOR_3DFACE);
  wc.lpszMenuName  = NULL;
  wc.lpfnWndProc   = WndProc;
  wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
  wc.hIcon         = LoadIcon(NULL, IDI_APPLICATION);

  RegisterClassW(&wc);

                WS_OVERLAPPEDWINDOW | WS_VISIBLE,
                100, 100, 350, 250, NULL, NULL, hInstance, NULL);  

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

  while( GetMessage(&msg, NULL, 0, 0)) {
    DispatchMessage(&msg);
  }

  return (int) msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, 
    WPARAM wParam, LPARAM lParam)

  switch(msg)  
  {
    case WM_CREATE:
            g_hbmBall = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_BALL));
            if(g_hbmBall == NULL)
                MessageBox(hwnd, "Could not load IDB_BALL!", "Error", MB_OK | MB_ICONEXCLAMATION);
        break;

case WM_PAINT:

            HDC hdcMem = CreateCompatibleDC(hdc);
            HBITMAP hbmOld = (HBITMAP)SelectObject(hdcMem, g_hbmBall);

            GetObject(g_hbmBall, sizeof(bm), &bm);

            BitBlt(hdc, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);

            SelectObject(hdcMem, hbmOld);
            DeleteDC(hdcMem);

            EndPaint(hwnd, &ps);
        }
        break;

    case WM_DESTROY:

      PostQuitMessage(0);
      DeleteObject(g_hbmBall);
      return 0;      
  }

  return DefWindowProcW(hwnd, msg, wParam, lParam);
}

您可以在编译时通过.rc 文件将图像数据添加到可执行文件的资源中，然后在运行时通过LoadImage() 加载图像。 .如果你把 STATIC在您的 UI 上进行控制，您可以向其发送 STM_SETIMAGE显示图像的消息。
