初学|错误ASP中查错之实例
有这样一个程序，是对Application集合中的元素进行活动的添加与删除，程序如下：
<% LANGUAGE=VBSCRIPT %>
<HTML>
<HEAD>
<TITLE>The Application Object</TITLE>
<STYLE TYPE="text/css">
BODY {font-family:Tahoma,Arial,sans-serif; font-size:10pt}
INPUT {font-family:Tahoma,Arial,sans-serif; font-size:9pt}
.heading {font-family:Tahoma,Arial,sans-serif; font-size:14pt; font-weight:bold}
.subhead {font-family:Tahoma,Arial,sans-serif; font-size:12pt; font-weight:bold; padding-bottom:5px}
.cite {font-family:Tahoma,Arial,sans-serif; font-size:8pt}
</STYLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF">
<SPAN CLASS="heading">The ASP Application Object</SPAN><HR>


<% 'look for a command sent from the FORM section buttons
If Len(Request.Form("cmdAdd")) Then                            ' 利用是否长度为0来判断
   strVarName = Request.Form("txtVarName")
   strVarValue = Request.Form("txtVarValue")
   Application.Lock
   Application(strVarName) = strVarValue                        ' 此处报错
   Application.Unlock
End If
If Len(Request.Form("cmdRemoveThis")) Then
   strToRemove = Request.Form("lstRemove")
   Application.Lock
   Application.Contents.Remove(strToRemove)
   Application.Unlock
End If
If Len(Request.Form("cmdRemoveAll")) Then
   Application.Lock
   Application.Contents.RemoveAll
   Application.Unlock
End If
