简介:本文详细讲述如何在Delphi中实现Sinleton,并解决实现中的一系列问题。
简介:在不同语言环境下,文字内容无障碍显示是支持国际化应用的一项基本要求,其具体实现是编程支持unicode字符集。通过对DelphiTLabel组件显示方法的分析.给出了构建支持Unicode文本显示新组件的一般方法.解决了DelphiWIN32VCL类库不支持Unicode文本显示的问题。
简介:Delphi把客户端软件做成下载控件形式的文件,放在http服务器端,用户使用时可以自动下载,版本可以自动更新,客户端变得非常简单,仅仅一个浏览器便能解决问题,避免了复杂的客户端软件程序的安装、使用和更新问题。服务程序实行了集中管理,较易于软件系统的维护和升级。
简介:AbstractMasquelet technique is one of the modalities for the treatment of long bone defect. Using cancellous bone graft to fill the bone defect is always a concern in children due to the small size of their iliac crest and open growth plate. We reported a case of 13-year-old male who presented with gap non-union of middle third of tibia. We applied a modified Masquelet technique by using only the cortical fibular graft instead of cancellous bone to fill the space surrounded by induced membrane. Fibula was used as a nonvascularized strut graft and matched stick graft to achieve complete union. We concluded that nonvascularized fibula grafting is an easy and effective option to fill the bone defect in children in the second stage of Masquelet technique.
