option explicit
dim fso,datefile,objText,nRead,objShell
const ForWriting=2,ForReading=1
set fso=CreateObject("scripting.FileSystemObject")
set objShell=CreateObject("WScript.Shell")
datefile=fso.GetParentFolderName( _
	WScript.ScriptFullName) & "\date.dat"
if not fso.FileExists(datefile) then
	MsgBox "注意：当前目录下未发现date.dat，视为脚本首次运行。" &_
		vbNewLine & vbNewLine & "date.dat记录着星期五重复的次数，" &_
		"必要时可手动更改，现在会将当前系统日期记为真实日期。" _
		,vbInformation,"提醒"
	set objText=fso.OpenTextFile(datefile,ForWriting,true)
	objText.WriteLine(0)
	objText.Close
end if
set objText=fso.OpenTextFile(datefile,ForReading,false)
nRead=objText.ReadLine
objText.Close
set objText=fso.OpenTextFile(datefile,ForWriting,true)
if Weekday(Date,vbMonday)>5 then
	if nRead=3 then
		objShell.Run "cmd /c date " & DateAdd("d",2,Date),0,true
		objText.WriteLine(0)
	else
		objShell.Run "cmd /c date " & DateAdd("d",5-Weekday(Date,vbMonday),Date),0,true
		objText.WriteLine(nRead+Weekday(Date,vbMonday)-5)
	end if
else
	objText.WriteLine(0)
end if
objText.Close
