怎么加载位图啊？

[SBNOone]

我通过应用程序向导搞了个单文挡的程序，想在里面加载一副指定的位图，要怎么办啊？

HBITMAP hbmp;
hbmp = (HBITMAP)LoadImage(AfxGetInstanceHandle(),
m_Photo,
IMAGE_BITMAP,
0,
0,
LR_LOADFROMFILE|LR_CREATEDIBSECTION);
CBitmap bmp;
bmp.Attach(hbmp);

pDC = this ->GetDC();
mDC = new CDC;
mDC ->CreateCompatibleDC(pDC);
CBitmap *oldBmp = mDC ->SelectObject(&bmp);
pDC ->BitBlt(25,25,320,253,mDC,50,50,SRCCOPY);

路径没写,重新帖一次!
HBITMAP hbmp;
hbmp = (HBITMAP)LoadImage(AfxGetInstanceHandle(),"D:\\1.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
CBitmap bmp;
bmp.Attach(hbmp);

pDC = this ->GetDC();
mDC = new CDC;
mDC ->CreateCompatibleDC(pDC);
CBitmap *oldBmp = mDC ->SelectObject(&bmp);
pDC ->BitBlt(25,25,320,253,mDC,50,50,SRCCOPY);

//通过资源画图
static void DrawBitmap(UINT bitmap,CDC *pDC,CRect rect)
{
CBitmap bmp;
if (bmp.LoadBitmap(bitmap))
{
BITMAP bmpInfo;
bmp.GetBitmap(&bmpInfo);
CDC dcMemory;
dcMemory.CreateCompatibleDC(pDC);
dcMemory.SelectObject(&bmp);
pDC->SetStretchBltMode(HALFTONE);
pDC->StretchBlt(rect.left,rect.top,rect.Width(),rect.Height(),&dcMemory,0,0,bmpInfo.bmWidth,bmpInfo.bmHeight,SRCCOPY);
}
}

//通过BMP文件画图
static void drawBitmapFormFile(CString BitmapFilePath,CDC *pDC,CRect rect)
{
HANDLE filehandle=::LoadImage(NULL,BitmapFilePath,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
if(filehandle!=NULL)
{
CBitmap bmp;
if(bmp.Attach(filehandle))
{
BITMAP bmpInfo;
bmp.GetBitmap(&bmpInfo);
CDC dcMemory;
dcMemory.CreateCompatibleDC(pDC);
dcMemory.SelectObject(&bmp);
pDC->SetStretchBltMode(HALFTONE);
pDC->StretchBlt(rect.left,rect.top,rect.Width(),rect.Height(),&dcMemory,0,0,bmpInfo.bmWidth,bmpInfo.bmHeight,SRCCOPY);
bmp.Detach();
}
}
}

HBITMAP hbmp;
hbmp = (HBITMAP)LoadImage(AfxGetInstanceHandle(),"D:\\1.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
CBitmap bmp;
bmp.Attach(hbmp);

pDC = this ->GetDC();
mDC = new CDC;
mDC ->CreateCompatibleDC(pDC);
CBitmap *oldBmp = mDC ->SelectObject(&bmp);
pDC ->BitBlt(25,25,320,253,mDC,50,50,SRCCOPY);
这段代码要写在 OnDraw函数里面吗？

[SBNOone]

哈哈哈哈
写写你们

[SBNOone]

不知道怎么搞的
把mDC = new CDC;改成 CDC mDC;
然后把pDC - >BitBlt(25,25,320,253,mDC,50,50,SRCCOPY); 改成pDC - >BitBlt(25,25,320,253,&mDC,50,50,SRCCOPY); 才能编译成功。

不知又如何将一个BMP或JPG等文件加载到一个变量中的呢?

[enoloo]

在view的initupdate中实现，或者在一个菜单命令中实现都可以。

哈哈，标记一下
