如果blnRet<> False然后Response.WriteblnRet is &安培; blnRet&
"< br>< br>"
blnRet = False

Because Boolean conditions always default to True. For example;
<%
Dim blnRet
If blnRet <> False Then Response.Write "blnRet is " & blnRet &
"<br><br>"
blnRet = False
If blnRet <> True Then Response.Write "blnRet is " & blnRet

因为if block当if
语句表达式为真时,执行if-then-else结构。假是永远不是真的所以否则阻止将
永远执行。

Because the "if block" of an if-then-else construct is executed when the if
statements expression is true. False is never true so the "else block" will
always be executed.
