  ' 这是一些随IIS4附带的一些组件(默认的)
  Dim theInstalledObjects(8)
  theInstalledObjects(0) = "MSWC.AdRotator"
  theInstalledObjects(1) = "MSWC.BrowserType"

  theInstalledObjects(8) = "MSWC.PermissionChecker"
  Function IsObjInstalled(strClassString)
  On Error Resume Next
  IsObjInstalled = False
  Err = 0
  Dim xTestObj
  Set xTestObj = Server.CreateObject(strClassString)
  If 0 = Err Then IsObjInstalled = True

  在下面的输入框中输入你要检测的组件的ProgId或则ClassId.
  如果你没有输入的话,将使用默认值。
  <FORM action=<%=Request.ServerVariables("SCRIPT_NAME")%> method=post>
  <input type=text value="" name="classname" size=40>
  <INPUT type=submit value=Submit>
  <INPUT type=reset value=Reset>
  </FORM>
  <%
  Dim strClass
  strClass = Trim(Request.Form("classname"))
  If "" <> strClass then
   Response.Write strClass & " "
   If Not IsObjInstalled(strClass) then
    Response.Write "<strong>本主页提供站点不支持这个组件</strong>"
   Else
    Response.Write "安装了,本主页提供站点支持使用这个组件!"
   End If
   Response.Write "<P>" & vbCrLf
  Else
  %>
  <TABLE BORDER=0>
  <%
  Dim i
  For i=0 to UBound(theInstalledObjects)
   Response.Write "<TR><TD>" & theInstalledObjects(i) & "</TD><TD>"
   If Not IsObjInstalled(theInstalledObjects(i)) Then
    Response.Write "<strong>本主页提供站点不支持这个组件</strong>"
   Else
    Response.Write "安装了,本主页提供站点支持使用这个组件!"
   End If
   Response.Write "</TD></TR>" & vbCrLf
  Next
