呵呵，比较困难学习中

AE+VB  与 AE+C# 相比，有什么优缺点吗？

<P>请教，需要先熟悉COM么</P>

<P>兄弟 真是服了你了  </P>
<P>幸好我有本书上又这些代码 FAILED  都写错了 改你这些代码 都够我重新写一遍的了 </P>
<P>上传代码要负责点嘛</P>
<P>这下没问题了</P>

哈  最近开始学习 VC+AO 的开发  挺感兴趣的 ！！<br>

<FONT size=1>有AO+C#的加我，新手入门，共同进步啊，自己一个人闷头傻学效率很低啊</FONT>

哎，跟楼上的一样。。。

<P>问题的关键是AO入门难！</P>
<P>AO+VC入门更难</P>
<P>VB的我倒有不少很好的参考资料</P>
<P>现在做VC 哎  真是两眼一吗黑！</P>
