Hello All,
Merry Christmas and Happy new year ..

I have to again do some changes to legacy MFC code !

There is some renderer function to draw lines..But now i need to add a rectangle to display the list of cells and their power levels.

I have added a following function:
Code:
void EmfCellListRend::DrawRectangle(EmfCellListRendDrawingParams* pParams, TDC& dc, CEmfCellList *pCelllist)
{
	ILogicalLayerManager&	rLogLayManager  = DataManager::GetInstance().GetLogicalLayer();

	//Rectangle(dc.GetHDC(), midPointX - m_markerSize, midPointY - m_markerSize, midPointX + m_markerSize, midPointY + m_markerSize);
	//GetWindowRect ( dc.GetHDC()
	//int rectHeight = DrawText( hMemDc, text.c_str(), text.size(), &rc, DT_CALCRECT |DT_WORDBREAK ); 
	// Get formating rectangle height

	//  Populate the cell list got from the renderer.  

	tstring message = _T("EMF Cell list");
	for (int i = 0; i < (int)pParams->GetNumCovCells(); i++)
	{
		const MultiTechCell* pObjCell((const MultiTechCell*)rLogLayManager.Find(OT_MULTI_TECH_CELL, pCelllist[i].m_CellKey));
	tstring str3 = _T("\n");
    tstring str4 = _T(pObjCell->GetID());
    tstring str5 = _T(std::to_string(pCelllist[i].m_fRxSignal_dBm));

		message	 +=str3+str4+str5;
	}
	HWND hwnd = WindowFromDC(dc);

	RECT rect;
	HWND bgHandle(0);
	GetClientRect(hwnd, &rect);
	SetTextColor(dc, 0x00000000);
	SetBkMode(dc, TRANSPARENT);
	rect.left = 40;
	rect.top = 10;
	DrawText(dc, message.c_str(), -1, &rect, DT_SINGLELINE | DT_NOCLIP );
	//DrawText(dc, message.c_str(), -1, &rect, DT_CALCRECT|DT_WORDBREAK );
	
	DeleteDC(dc);

	dc.RestorePen();
}

The above drawtext somehow doesnot honour new lines..
Also if i change to below commented Drawtext, it doesnot display anything at all..


I tried to install and create a new MFC project in my home PC, and both of above DrawText doesnot work !!!... I knew little MFC but never drew with MFC

Thanks a lot for the help
