if(connectmode == extensibility.ext_connectmode.ext_cm_uisetup || connectmode == extensibility.ext_connectmode.ext_cm_startup || connectmode == extensibility.ext_connectmode.ext_cm_afterstartup) // this line will work when u choose addin in addin manager 這樣子，在vs的addin manager中選中插件時，插件才會重新顯示出來，一般的范例中，只有前兩個判斷
（2）querystate中，設(shè)置state時，要使用下面語句
if( 是你加入的command ) { if( 滿足顯示的條件 ) status = (vscommandstatus)vscommandstatus.vscommandstatussupported|vscommandstatus.vscommandstatusenabled; else status = (vscommandstatus)vscommandstatus.vscommandstatussupported; } else status = (vscommandstatus)vscommandstatus.vscommandstatusunsupported; 這樣做，才能在條件不滿足時，插件的菜單變灰
