MFC多文档项目中新建子文档OnSize时文档内部标签闪屏

[zcy790811]

MDI中自义定了一个子文档AFrame和Aview, 其中Aview继承自CFormView，然后新建一个A文档窗口之后呢在改变A文档窗口大小的时候，A文档内部的内容在闪屏，求助啊！
A文档内部相关的代码如下:

void CAView::OnSize(UINT nType, int cx, int cy)
{
	//CFormView::OnSize(nType, cx, cy);

	CRect dlgRect;
	this->GetClientRect(dlgRect);
	//InvalidateRect(CRect(MARGIN_LEFT_BATPANE, 0, cx, cy), TRUE);

	if (batterysPanePic.m_hWnd) {
		
		batterysPanePic.MoveWindow(MARGIN_LEFT_BATPANE, MARGIN_TOP_BATPANE, dlgRect.Width(), dlgRect.Height(), TRUE);
		if (pbatterysDlg != NULL)
			pbatterysDlg->OnSize(0, dlgRect.Width() - MARGIN_LEFT_BATPANE, dlgRect.Height() - MARGIN_TOP_BATPANE);
		if (tbatterysDlg != NULL)
			tbatterysDlg->OnSize(0, dlgRect.Width() - MARGIN_LEFT_BATPANE, dlgRect.Height() - MARGIN_TOP_BATPANE);
		if (fbatterysDlg != NULL)
			fbatterysDlg->OnSize(0, dlgRect.Width() - MARGIN_LEFT_BATPANE, dlgRect.Height() - MARGIN_TOP_BATPANE);
		if (ebatterysDlg != NULL)
			ebatterysDlg->OnSize(0, dlgRect.Width() - MARGIN_LEFT_BATPANE, dlgRect.Height() - MARGIN_TOP_BATPANE);

	}
}
BOOL CBatteryCheckView::OnEraseBkgnd(CDC* pDC)
{
	return CFormView::OnEraseBkgnd(pDC);
}

学会使用Spy++

最后利用，LockWindowUpdate,改变大小后释放windowUpdate();解决问题。
