给按钮加载位图，资源释放的问题。

给按钮加载位图，资源释放的问题。
void Fun()
{
CButton *pButton = (CButton *)GetDlgItem(IDC_BUTTON1);
pButton->ModifyStyle(0,WS_CHILD|BS_BITMAP,NULL);
HBITMAP hIcon = (HBITMAP)LoadImage(AfxGetInstanceHandle(),_T("位图1.bmp"),
IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION|LR_LOADFROMFILE);
pButton->SetBitmap( hIcon);

if ( hIcon != NULL )
{
hIcon = NULL;
delete hIcon ;
}
if ( pButton != NULL)
{
pButton = NULL;
delete pButton ;
}
}

以上是我的源码。关于后面释放hIcon 和 pButton 资源的代码，是不是有问题啊？为什么每次都感觉释放不干净啊??? 应该如何写释放资源的代码才是最安全的呢？？？

The system automatically deletes these resources when the process that created them terminates; however, calling the appropriate function saves memory and decreases the size of the working set of the process. LoadImage要deleteobject

用deleteobject的话，图就出不来了。deleteobject适合在关闭程序的时候调用。 我就是想给按钮放一个图上去，还要不停的变换图片呢~

你还是看看cbuttonst这个类把

deleteobject 即可
