我在编写扫雷游戏时遇到了这个问题。我使用位图来表示数字,地雷和空白。我想我已经在资源文件
中正确注册了它们IDI_0 BITMAP "D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\empty.bmp"
IDI_1 BITMAP "D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\1.bmp"
IDI_2 BITMAP "D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\2.bmp"
IDI_3 BITMAP "D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\3.bmp"
和头文件
#define IDI_0 200
#define IDI_1 201
#define IDI_2 202
#define IDI_3 203
我按照这样加载它们
h0 = (HBITMAP)LoadImage(hInst, MAKEINTRESOURCE(IDI_0), IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION);
h1 = (HBITMAP)LoadImage(hInst, MAKEINTRESOURCE(IDI_1), IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION);
h2 = (HBITMAP)LoadImage(hInst, MAKEINTRESOURCE(IDI_2), IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION);
h3 = (HBITMAP)LoadImage(hInst, MAKEINTRESOURCE(IDI_3), IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION);
我还使用resourcehacker检查了exe文件并找到了所有位图。
我不明白的是,当我运行游戏时,有时候(~50%)会弹出
Error 1812: The specified image file did not contain a resource section.
或
Error 1813: The specified resource type cannot be found.
但是如果我从像这样的文件中加载它们
h0 = (HBITMAP)LoadImage(NULL, L"D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\empty.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
h1 = (HBITMAP)LoadImage(NULL, L"D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\1.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
h2 = (HBITMAP)LoadImage(NULL, L"D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\2.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
h3 = (HBITMAP)LoadImage(NULL, L"D:\\User\\Mark\\Documents\\C++\\win32\\MineSweeper\\MineSweeper\\3.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
一切正常。
任何想法或建议都将不胜感激。谢谢!

我个人考虑使用GDI +来加载图片。您仍然可以从磁盘文件或应用程序的资源部分加载。它还为您提供了访问Windows本机支持的所有图像格式(BMP,GIF,JPEG,PNG,TIFF,Exif,WMF和EMF)的优势
要使用它,您只需先初始化GDI +,然后在程序退出前执行关机。
这是我用来从磁盘文件加载的函数:
// BMP, GIF, JPEG, PNG, TIFF, Exif, WMF, and EMF
HBITMAP mLoadImageFile(wchar_t *filename)
{
HBITMAP result = NULL;
Bitmap bitmap(filename, false);
bitmap.GetHBITMAP(0, &result);
return result;
}
如果我们有一个包含以下内容的资源文件:
IDR_PNG1 RT_PNG ".\\girl.png"
IDR_JPG1 RT_JPG ".\\rssLogo.jpg"
然后我们可以这样加载每个图像:
HBITMAP png = loadImgResource(IDR_PNG1, L"RT_PNG");
HBITMAP jpg = loadImgResource(IDR_JPG1, L"RT_JPG");
我用来从资源加载的两个函数。您注意到我在第二个函数中的GetModuleHandle(0)中进行了硬编码 - 如果您想从当前模块以外的任何模块(dll,exe)读取,请更改此项。
// BMP, GIF, JPEG, PNG, TIFF, Exif, WMF, and EMF
HBITMAP loadImgResource(wchar_t *pName, wchar_t *pType, HMODULE hInst)
{
Gdiplus::Bitmap *m_pBitmap;
HBITMAP result=NULL;
HRSRC hResource = FindResource(hInst, pName, pType);
if (!hResource)
return NULL;
DWORD imgSize = SizeofResource(hInst, hResource);
if (!imgSize)
return NULL;
const void *pResourceData = LockResource(LoadResource(hInst, hResource));
if (!pResourceData)
return NULL;
HANDLE m_hBuffer = GlobalAlloc(GMEM_MOVEABLE, imgSize);
if (m_hBuffer)
{
void* pBuffer = GlobalLock(m_hBuffer);
if (pBuffer)
{
CopyMemory(pBuffer, pResourceData, imgSize);
IStream* pStream = NULL;
if (CreateStreamOnHGlobal(m_hBuffer, FALSE, &pStream) == S_OK)
{
m_pBitmap = Gdiplus::Bitmap::FromStream(pStream);
pStream->Release();
if (m_pBitmap)
{
if (m_pBitmap->GetLastStatus() == Gdiplus::Ok)
{
m_pBitmap->GetHBITMAP(0, &result);
delete m_pBitmap;
}
}
}
GlobalUnlock(m_hBuffer);
}
GlobalFree(m_hBuffer);
}
return result;
}
HBITMAP loadImgResource(WORD resNum, LPWSTR pType)
{
return loadImgResource(MAKEINTRESOURCE(resNum), pType, GetModuleHandle(0));//hInst);
}
