UC知道判断数组为空
来源：百度知道 编辑：UC知道 时间：2024/06/07 23:38:41
while i>0
code=replace(code,"$title$",Application(Application("Z")(2,Z_P))(1,earr(rndNumber(0,ubound(earr)))),1,1)
i=instr(i,code,"$title$")
wend
当Application(Application("Z")(2,Z_P))(1,earr(rndNumber(0,ubound(earr))))为空时,就会提示
类型不匹配: 'ubound'
如何判断他,如果数组为空时,则用"标题"替代(不含引号)
code=replace(code,"$title$",Application(Application("Z")(2,Z_P))(1,earr(rndNumber(0,ubound(earr)))),1,1)
i=instr(i,code,"$title$")
wend
当Application(Application("Z")(2,Z_P))(1,earr(rndNumber(0,ubound(earr))))为空时,就会提示

try
catch好了
你试试这个，那个类型不匹配的错误代码不知道，你查下msdn，然后可以具体处理，我现在只是显示出来
while i>0
try
code=replace(code,"$title$",Application(Application("Z")(2,Z_P))(1,earr(rndNumber(0,ubound(earr)))),1,1)
i=instr(i,code,"$title$")
catch obj as exception
msgbox("出错了")
end try
wend
on error resume next
while i>0
code=replace(code,"$title$",Application(Application("Z")(2,Z_P))(1,earr(rndNumber(0,ubound(earr)))),1,1)
if err then
err.clear
code=replace(code,"$title$","你要使用的标题",1,1)
end if
i=instr(i,code,"$title$")
wend
Try
'有可能会出错的语句
Catch LeafError As Exception
'如果出错了执行的语句
End Try
最好的办法,为空之前,REDIM(0) 一下,
或者用VALTYPE这个函数看看
Application是什么？
