Thanks

Maybe with some more info on your code we could help.

Here's the code i use to create the balloon

m_bTop = bTop;
	// TODO: Add your specialized code here and/or call the base class
	int iStringWidht=1, iStringHeight=1, curWidth;
	int lastPos=-1, curPos = -1;
	curPos = m_strMessage.Find("\n", curPos+1);
	while (curPos > lastPos) {
		curWidth = m_strMessage.Mid(lastPos+1, curPos-lastPos+1).GetLength();
		if(curWidth > iStringWidht)
			iStringWidht = curWidth;
		lastPos = curPos;
		iStringHeight++;
		curPos = m_strMessage.Find("\n", curPos+1);
	}
	if (iStringHeight == 1)
		iStringWidht = m_strMessage.GetLength();
	CRect textRect;
	WINDOWPLACEMENT place;
	m_pParent->GetWindowPlacement(&place);
	CRect parentRect(place.rcNormalPosition);
	CPoint ptMiddle;
	ptMiddle.x = place.rcNormalPosition.left + (place.rcNormalPosition.right-place.rcNormalPosition.left)/2;
	if (bTop) {
		ptMiddle.y = place.rcNormalPosition.top;
		textRect = CRect(ptMiddle.x - (iStringWidht*3.5), ptMiddle.y-(17*iStringHeight)-35, ptMiddle.x + (iStringWidht*3.5), ptMiddle.y);
	}
	else {
		ptMiddle.y = place.rcNormalPosition.bottom;
		textRect = CRect(ptMiddle.x - (iStringWidht*3.5), ptMiddle.y, ptMiddle.x + (iStringWidht*3.5), ptMiddle.y+(17*iStringHeight)+35);
	}
	

	return CWnd::Create(BALLONMESSAGE_CLASSNAME, _T(""), WS_CHILD|WS_OVERLAPPED, textRect, m_pParent->GetParent(), 1);

Result is attached as a jpg

The problem is because you have created a child window (WS_CHILD style) which can reside only in the client area of its parent.
You have to create a top-level one. Set WS_POPUP style for your needs since WS_OVERLAPPED always has a caption and a border. Of course remove WS_CHILD as well.
