趁著禮拜天有時間準備開發我在WinCE平臺上的第一個例子 Hello World。3GEYE*Zg!q_l[7[

%zR'B*h1q'X5s \ Y3體驗到開發J2ME Hello World的簡單。認識到Andriod開發也是特簡單。現在來體驗下微軟的技術。大家都說簡單。我看果然是簡單。
YK,Z(lC3K3IDE安裝時非常簡單的。直接安裝VS2005，然后下一步，下一步就OK了。3GEYE?X2p}.o4Xw!b[

現在建立一個簡單的C# WinCE工程。WinCE支持很多種語言開發。至于怎么建立工程我就不說了。看看程序的入口吧

上面的方法跟paint很類似，不過對于WInCE來說不僅僅是Canvas才可以繪制圖形幾乎沒個控件都是可以繪制圖形的。
