MFC随着对话框全屏控件，图片移动相应的位置

[一只正在啃的蜗牛]

MFC随着对话框全屏控件，图片移动相应的位置，
RectToRect(mDlgRect,recNow,mRectArray[0],false);
RectToRect(mDlgRect,recNow,mRectArray[1],false);
RectToRect(mDlgRect,recNow,mRectArray[2],false);
SetnIDRect(IDC_STATIC_COMM_PORT,mRectArray[0]);
SetnIDRect(IDC_EDIT_COMM_PORT,mRectArray[1]);
SetnIDRect(IDC_STATIC_SLAVE_ADDRESS,mRectArray[2]
这样已经在对话框已经有位置的在全屏时怎么编辑

按键里面的位图要全屏的话怎么编写

[一只正在啃的蜗牛]

按钮全屏，按钮里面的位图大小不变，要怎么样才能相应改变

[zgl7903]

重载CButton类， 自己处理 WM_PAINT 用 StretchBlt 贴图

[赵4老师]

建议直接上WPF

没明白你的问题

这是只改变一个？

补
void CCenterDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else

if((SC_RESTORE==nID)||(SC_MAXIMIZE==nID))
{

}
CDialog::OnSysCommand(nID, lParam);
}
}

自己处理 WM_PAINT 用 StretchBlt 贴图,,,有例子？

[zgl7903]

void CMyButton::OnPaint() 
{
	CPaintDC dc(this); // device context for painting
	
	// TODO: Add your message handler code here	
	// Do not call CButton::OnPaint() for painting messages

  
  CDC *pDC = &dc;

  //保存设备现场
  int nSaveDC = pDC->SaveDC();

  //获取客户区位置&大小
  CRect rcRect;
  GetClientRect(&rcRect);
  
  //获取位图
  HBITMAP hBmp = GetBitmap();
  BITMAP bmpInfo = {0};
  if(hBmp && GetObject(hBmp, sizeof(bmpInfo), &bmpInfo))
  {
    //创建兼容DC
    CDC memDC;
    memDC.CreateCompatibleDC(pDC);
    //选人位图
    HGDIOBJ hOldBmp = memDC.SelectObject(hBmp);

    //设置缩放模式
    pDC->SetStretchBltMode(HALFTONE); 
    //缩放贴图
    pDC->StretchBlt(rcRect.left, rcRect.top, rcRect.Width(), rcRect.Height(),
      &memDC, 
      0, 0, bmpInfo.bmWidth, bmpInfo.bmHeight,
      SRCCOPY);  
    
    //恢复内存DC位图
    memDC.SelectObject(hOldBmp);
  }
  
  //恢复现场
  pDC->RestoreDC(nSaveDC);
}

不好意思，发帖的新手，请问下如何给回复帖子的人分数？

[一只正在啃的蜗牛]

因为我有多个按键位图，这个执行代表哪个，，又在哪个地方改换成另外的，

[schlafenhamster]

?这个执行代表哪个?"

CWnd::GetDlgCtrlID
int GetDlgCtrlID( ) const;

Return Value

The numeric identifier of the CWnd child window if the function is successful; otherwise 0.

该函数 可以 区分 那个 按钮

[一只正在啃的蜗牛]

RectToRect(const CRect& recSrc, const CRect& recDest, CRect& recRes, bool bReSize)
可以设置控件的大小？还是用什么设置大小的
