推荐答案

没有与图片控制相关的特定类.通常将其视为静态控件.您可以创建CStaic对象，并将图片控件映射到该对象.如果需要进行某种定制，则可以从CStatic中拥有自己的类派生.
在指定您要实际使用图片控件执行的操作时，可以给出进一步的解决方案

There is no specfic class related to picture control. It normally treated like a static control.you can create an object of CStaic and map your picture control to this object. If you need to do some kind of customization you can have your own class dervide from CStatic.
further solutions can be given on specifying that what you are actually trying to do with your picture control

根据建议，您可以使用CStatic类.
您必须:

• 使用 LoadImage 从文件加载位图[ ^ ]函数.
• 调用 CStatic :: SetBitmap [ ^ ]方法.

As suggested, you may use a the CStatic class.
You have to:

• Load the bitmap from file, using the LoadImage[^] function.
• Call the CStatic::SetBitmap[^] method.

如果您尝试使用位图，以下代码可能会起作用

if you are trying to use a bitmap.following code may work

CBitmap* pBitmap;
 pBitmap=new CBitmap();
 pBitmap->LoadBitmap(IDB_BITMAP1);
 CDC* pDC = m_PicCtrl.GetDC();
 CRect rect;
 m_PicCtrl.GetClientRect(rect);
 CDC dc;
 dc.CreateCompatibleDC(pDC);
 dc.SelectObject(pBitmap);
 pDC->BitBlt (0, 0, rect.Width(),rect.Height(), &dc,0, 0, SRCCOPY);
 delete pBitmap;
 pBitmap = 0;

使用StretchBlt()代替BitBlt()来调整图片的大小，具体取决于图片控件的大小

use StretchBlt() instead of BitBlt() to adjust the size of image depending on the size of your picture control
