用lotusscript动态刷新登录页表单设计

用lotusscript动态刷新登录页表单设计
1、到服务器上查找是否有domcfg.nsf库，如果没有，直接把自己设计的domcfg.nsf库考到服务器上，如果有，执行2
2、从服务器的domcfg.nsf库中查找登录页，如果有，先将“$$LoginUserForm”表单导成dxl，然后将form节点下属的name节点的nodevalue值改成“$$LoginUserForm”+时间，然后再把dxl文件导到domcfg.nsf库中（该操作是保存原有的登录页表单）。
3、将自己设计的库中的“$$LoginUserForm”表单导成dxl，然后再导入到服务器的domcfg.nsf库中。

另：
    如果想直接修改某个表单的设计也是同样的道理。因为domino的数据库设计、表单、视图等等都是标准的xml文件，所以如果要修改表单设计，可以先把表单导成dxl文件（xml格式），然后，直接对dxl中具体的node作修改，然后重新导入dxl文件即可实现对表单设计的动态修改。
