MORE INFORMATION

Sample Code

   void ResizeEdit(HWND hwndEdit, HFONT hNewFont)
   {
      HFONT       hSysFont,
                  hOldFont;
      HDC         hdc;
      TEXTMETRIC  tmNew,
                  tmSys;
      RECT        rc;
      int         nTemp;

      // Get the DC for the edit control.
      hdc = GetDC(hwndEdit);

      // Get the metrics for the system font.
      hSysFont = GetStockObject(SYSTEM_FONT);
      hOldFont = SelectObject(hdc, hSysFont);
      GetTextMetrics(hdc, &tmSys);

      // Get the metrics for the new font.
      SelectObject(hdc, hNewFont);
      GetTextMetrics(hdc, &tmNew);

      // Select the original font back into the DC and release the DC.
      SelectObject(hdc, hOldFont);
      DeleteObject(hSysFont);
      ReleaseDC(hwndEdit, hdc);

      // Calculate the new height for the edit control.
      nTemp = tmNew.tmHeight + (min(tmNew.tmHeight, tmSys.tmHeight)/2) +
      (GetSystemMetrics(SM_CYEDGE) * 2);

      // Re-size the edit control.
      GetWindowRect(hwndEdit, &rc);
      MapWindowPoints(HWND_DESKTOP, GetParent(hwndEdit), (LPPOINT)&rc, 2);
      MoveWindow( hwndEdit,
                  rc.left,
                  rc.top,
                  rc.right - rc.left,
                  nTemp,
                  TRUE);
   }
