}自动生成的mfc框架，只在上面部分做了修改想引入位图作为框体背景，但是提示错误error C2582: 'CBitmap' : 'operator =' function is unavailable，就是OnDraw函数里那句bitmap=(HBITMAP)LoadImage(NULL,"IDB_BACKGROUND.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE);报错的，跪求大神指导啊

LoadImage返回的HBITMAP
HBITMAP hBmp= (HBITMAP)LoadImage(NULL, m_csFilePath,IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_LOADFROMFILE);

bitmap.Attach(hBmp);

我看你这个bitmap的路径貌似不对啊，要不你就这样
bitmap.LoadBitmap(...);

[运算符科技]

代码没看，不过导入位图失败，很有可能是因为你被后缀欺骗了。改后缀为jpg试试。

[Quote=引用 1 楼 的回复:]

HBITMAP hBmp= (HBITMAP)LoadImage(NULL, m_csFilePath,IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_LOADFROMFILE);

bitmap.Attach(hBmp);

bitmap.LoadBitmap……
[/Quote]不报错了，但是在框体中显示不了图片额

[dahaiI0]

你这个图片是BMP吧，有没有导入到资源里呢？这个ID是不是导入后的bmp ID?
对于第一种方法加载bmp，路径对不对，看下LoadImage的返回值是不是0，把你加载的代码贴上来
对于第二种，如果bmp已经导入到资源里，直接这样
bitmap.LoadBitmap(IDB_BACKGROUND);

[就叫我海]

static int i = 0;
if(i==0)
{
     HBITMAP hbmp=(HBITMAP)LoadImage (NULL,"IDB_BACKGROUND.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
     BEGIN.CreateCompatibleDC(pDC);
     BEGIN.SelectObject(bitmap);
     bitmap.Attach(hbmp);
     BEGIN.CreateCompatibleDC(pDC);
     BEGIN.SelectObject(bitmap);
     i=1;
}
pDC->BitBlt(0,0,119,64,&BEGIN,0,0,SRCCOPY);

[写不动代码的人]

建议你用GDI+ 支持的格式较多

LoadImage()调用成功？
