<P>楼主的问题估计是没有进行控件license初始化，不妨添加以下代码试试</P>
<P><FONT color=#008000>'Determine if the product is available</FONT><BR>  <CODE><FONT color=#0000ff>If</FONT></CODE> m_pAoInitialize.IsProductCodeAvailable(esriLicenseProductCodeEngine) = esriLicenseAvailable <CODE><FONT color=#0000ff>Then<BR>    If</FONT></CODE> m_pAoInitialize.Initialize(esriLicenseProductCodeEngine) <> esriLicenseCheckedOut <CODE><FONT color=#0000ff>Then</FONT></CODE><BR>      MsgBox "The initialization failed. This application cannot run!"<BR>    <CODE><FONT color=#0000ff>End If<BR>  Else</FONT></CODE><BR>    MsgBox "The ArcGIS Engine product is unavailable. This application cannot run!"<BR><CODE><FONT color=#0000ff>  End If</FONT></CODE><BR></P>

<P>也不能用,估计license过期了,请问哪里有最新的arcgis engine 9.2的license下载,万分感谢!</P>
