 又自己解决的。原来是少用一个俗称的画布CBitmap 程序代码： pWnd = GetDlgItem(IDC_STC); 用完后再释放一下就OK了Rect = new CRect(); pWnd->GetClientRect(Rect); pDC = pWnd->GetDC(); RecordDC = new CDC; RecordMap = new CBitmap(); RecordDC->CreateCompatibleDC(pDC); RecordMap->CreateCompatibleBitmap(pDC,Rect->right,Rect->bottom); pOldMap = RecordDC->SelectObject(RecordMap); RecordDC->BitBlt(Rect->left,Rect->top,Rect->right,Rect->bottom,pDC,0,0,SRCCOPY); |
程序代码： pWnd = GetDlgItem(IDC_STC);
Rect = new CRect();
pWnd->GetClientRect(Rect);
pDC = pWnd->GetDC();
RecordDC = new CDC;
RecordDC->CreateCompatibleDC(pDC);
RecordDC->BitBlt(Rect->left,Rect->top,Rect->right,Rect->bottom,pDC,0,0,SRCCOPY);
以上是复制按钮中的代码。Rect = new CRect();
pWnd->GetClientRect(Rect);
pDC = pWnd->GetDC();
RecordDC = new CDC;
RecordDC->CreateCompatibleDC(pDC);
RecordDC->BitBlt(Rect->left,Rect->top,Rect->right,Rect->bottom,pDC,0,0,SRCCOPY);
pDC->BitBlt(Rect->left,Rect->top,Rect->right,Rect->bottom,RecordDC,0,0,SRCCOPY);
OnPaint();
以上是黏贴按钮中的代码OnPaint();
CDC* pDC;
CWnd* pWnd;
CRect* Rect;
CDC* RecordDC;
这个是定义。CWnd* pWnd;
CRect* Rect;
CDC* RecordDC;
IDC_STC是窗口中的一个“框架”类型的图像
为什么实现不了保存图像的功能呢？
