ASP学习:远程注册自己的组件

把asp程序作成dll很多好处，但是有一点，该dll必须注册才能在asp中调用。如果是自己的服务器那还好，但如果是租用的虚拟服务器，就没办法使用了。
怎样在远程主机上注册我们的dll呢？在服务器端使用shell！！！

让我们先将自己的dll文件通过ftp或http上传到服务器上，然后作一个asp程序，调用wscript.shell来执行regsvr32命令：
set oshell = createobject ("wscript.shell")
oshell.run "c:\winnt\system32\regsvr32.exe /s d:\xxx.dll", 0, false
当然如果对方的服务器安全搞的很好的话，这个代码也许就不能用了，但不管怎么样，学习一下也是好的，：）
在这里也要提醒那些出租空间的朋友，你的服务器是否限制了使用wscript.shell的权限？还是小心为妙

完整代码如下，保存为.asp即可使用：

<% response.buffer = true %>
<% server.scripttimeout = 500
dim frmfolderpath, frmfilepath

frmfolderpath = request.form("frmfolderpath")
frmfilepath = request.form("frmdllpath")
frmmethod = request.form("frmmethod")
btnreg = request.form("btnreg")
%>
