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")
