趁着礼拜天有时间准备开发我在WinCE平台上的第一个例子 Hello World。3GEYE*Zg!q_l[7[

%zR'B*h1q'X5s \ Y3体验到开发J2ME Hello World的简单。认识到Andriod开发也是特简单。现在来体验下微软的技术。大家都说简单。我看果然是简单。
YK,Z(lC3K3IDE安装时非常简单的。直接安装VS2005，然后下一步，下一步就OK了。3GEYE?X2p}.o4Xw!b[

现在建立一个简单的C# WinCE工程。WinCE支持很多种语言开发。至于怎么建立工程我就不说了。看看程序的入口吧

上面的方法跟paint很类似，不过对于WInCE来说不仅仅是Canvas才可以绘制图形几乎没个控件都是可以绘制图形的。
