返回信息流我想利用打开对话框读取一BMP图像，没法正常读，报错一内在地址不能read
主要代码是这样的
void CMy1View::OnFileOpen()
{
// TODO: Add your command handler code here
char szFilter[] = "Bitmap(*.BMP)|*.BMP||";
CFileDialog dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY,szFilter);
if(dlg.DoModal() == IDOK){
CString filename = dlg.GetPathName();
if(LoadBmpFromFile(filename)){
bLoadBmpFromFile = TRUE;
Invalidate(TRUE);
}
}
}
BOOL CMy1View::LoadBmpFromFile(CString szPathName)
{
Destroy();
HBITMAP hBitmap = (HBITMAP)::LoadImage(NULL,szPathName,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
if(hBitmap){
m_pBmp = new CBitmap();
m_pBmp->Attach(hBitmap);
return true;
}
return false;
}
void CMy1View::OnDraw(CDC* pDC)
{
CMy1Doc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
CDC dcMemory;
CBitmap* PoldBmp = NULL;
dcMemory.CreateCompatibleDC(pDC);
PoldBmp = dcMemory.SelectObject(m_pBmp);
pDC->BitBlt(m_orgpoint.x,m_orgpoint.y,m_size.cx,m_size.cy,&dcMemory,0,0,SRCCOPY);
dcMemory.SelectObject(PoldBmp);
}
下面是调试信息：
