问题描述
我的浏览按钮代码是
void CFileOpenDlg::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
CFileDialog dlg(TRUE);
int result=dlg.DoModal();
if(result==IDOK)
{
path=dlg.GetPathName();
UpdateData(FALSE);
}
}
这是从资源加载图片的代码但不适用于从文件加载图像。我知道 LoadImage();
是用于这个,但如何?如何编辑此代码从文件加载图像。 Plzz帮助.....

CRect r;
CBitmap* m_bitmap;
CDC dc, *pDC;
BITMAP bmp;
m_bitmap = new CBitmap();
m_bitmap->LoadBitmapW(IDB_BITMAP1);
m_bitmap->GetBitmap(&bmp);
pDC = this->GetDC();
dc.CreateCompatibleDC(pDC);
dc.SelectObject(m_bitmap);
pDC->BitBlt(200, 200, bmp.bmWidth, bmp.bmHeight, &dc,0 , 0, SRCCOPY);
m_bitmap->DeleteObject();
m_bitmap->Detach();
}
推荐答案
HANDLE hBitMap = ::LoadImage(0, "c:\\mybmp.bmp",IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
CBitmap bmp;
bmp.Attach((HBITMAP)hBitMap);
