WTL Picture Control显示图片

1、在对话框上新建一个Picture Control ID为：IDC_STATIC_IMG

2、添加图片资源ID:IDB_BITMAP1(选中Bitmap点击导入，选择bmp图片资源)

实现：

CWindow wnd = this->GetDlgItem(IDC_STATIC_IMG);
	CStatic *pImg = (CStatic*)&wnd;
	pImg->ModifyStyle(0xF, SS_BITMAP | SS_CENTERIMAGE);

	hBitmap = AtlLoadBitmap(MAKEINTRESOURCE(IDB_BITMAP1));

	pImg->SetBitmap(hBitmap);

也可以使用CBitmap

CBitmap bitmap;
m_picture.Create("",WS_CHILD  and  WS_VISIBLE  and  SS_CENTERIMAGE  and  SS_BITMAP,
CRect(0,0,180,160),this,IDC_STATIC1);
bitmap.LoadBitmap(IDB_BITMAP1);
m_picture.SetBitmap(bitmap.Detach());

这里只显示bmp图片有点局限性，如何显示png,jpg图片呢？

CImage img;
CWindow wnd = this->GetDlgItem(IDC_STATIC_IMG);
CStatic *pImg = (CStatic*)&wnd;
pImg->ModifyStyle(0xF, SS_BITMAP | SS_CENTERIMAGE);
img.Load(TEXT("ing.png"));
pImg->SetBitmap(img.Detach());
