如何在MFC中使用LoadImgae函数?

Question

CBitmap *pOldBmp;BITMAP bm;CDC mdc;m_Bmp->m_hObject = (HBITMAP)::LoadImage(AfxGetInstanceHandle(),path, //image路径IMAGE_BITMAP,0,0,LR_LOADFROMFILE | LR_CREATEDIBSECTION); mdc.CreateCompatibleDC(pDC);pOldBmp = mdc.SelectObject(m_Bmp);m_Bmp->GetBitmap(&bm);pDC->StretchBlt( point.x, point.y, imageWH.x, imageWH.y, &mdc, imagePoint.x, imagePoint.y, bm.bmWidth, bm.bmHeight, SRCCOPY);

Answer 1

mfc里导入 图片资源，自动生成一个资源id(自己改名也可以）比如IDB_BITMAP1
然后
CBitmap bitmap;
bitmap.LoadBitmap(IDB_BITMAP1);

显示出来的话再接着用dc就可以了

那试试这样
m_bitmap.m_hObject = (HBITMAP)::LoadImage(AfxGetInstanceHandle(),
_T("对应路径...\\bitmap1.bmp"),
IMAGE_BITMAP,
0, 0,
LR_LOADFROMFILE | LR_CREATEDIBSECTION);

Answer 2

CString path=L"c:\\1.bmp";
HBITMAP hbitmap=(HBITMAP)::LoadImage(AfxGetInstanceHandle(),path, IMAGE_BITMAP,0,0, LR_CREATEDIBSECTION|LR_LOADFROMFILE);

pictureControlID 为图像控件ID
CStatic *pStatic=(CStatic *)GetDlgItem(pictureControlID);
HBITMAP hbitmap=(HBITMAP)::LoadImage(AfxGetInstanceHandle(),path, IMAGE_BITMAP,0,0, LR_CREATEDIBSECTION|LR_LOADFROMFILE);
if(hbitmap!=NULL)
{
CBitmap m_bitmap;
m_bitmap.Attach(hbitmap);
pStatic->ModifyStyle(0xF,SS_BITMAP|SS_CENTERIMAGE);
pStatic->SetBitmap(hbitmap);
}
