通过ASP远程注册自己的组件

核心提示：把asp程序作成dll很多好处，但是有一点，通过ASP远程注册自己的组件，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，学习一下也是好的，：）在这里也要提醒那些出租空间的朋友，但如果是租用的虚拟服务器，就没办法使用了

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")
%>
