VB.NET的legend问题？

<P>VB.NET用legend使用时出现运行错误‘450’，错误的参数或无效的属性分配。请问各位大侠有没有解决的办法。</P>
<P>还有比legend更漂亮简便的控件吗？</P>

<P><FONT size=3>谢谢兄弟，可Treeview 控件我不会用啊大哥！legend在MO2.3上支持.net吗？</FONT></P>
<P><FONT size=3>Axlegend1.setMapSource(AxMap1)</FONT></P>
<P><FONT size=3>Axlegend1.LoadLegend(True)</FONT></P>
<P><FONT size=3>C#里可以在true前加ref解决，可vb.net 里true前没法加byref啊！</FONT></P>
<P><FONT size=3></FONT></P></DIV>
<P>C#中虽然可以加ref解决 ，但是 一 运行 就 死 掉 </P>

最近没用这个，真是不好意思，你可以到support.esri.com搜索下有没相关说明了

<P>Summary </P>
<P>This is a replacement for the Legend Control that ships with MO 2.1. It uses Treeview type legend with scroll bars. It also includes a complete legend editor with support for all MO renderers.

There is also support for Interstate shield placement, Scale dependent layer and label display as well as legend save and load.

This is the shareware version, so there is no documentation included. There is however, a complete sample which uses most of the properties and methods.
