unzipping a file in classic asp

I'm trying to use an unzip/zip class. I need to unzip a zip file after upload. i modified "sleep" function to check "controller" function per intSeconds value and added "controller" function to check file count on target folder. You can see a code part below.

zip file is successfully unzipped with this functions but page progress never ending. i need to restart iis after to use this function.

Original code on : Class CompressedFolder

<%
    Set objShell = CreateObject("Shell.Application")
    Set objFso   = CreateObject("Scripting.FileSystemObject")

    Function ExtractAll(strZipFile, strFolder)
        If Not objFso.FolderExists(strFolder) Then objFso.CreateFolder(strFolder)
        intCount = objShell.NameSpace(strFolder).Items.Count
        Set colItems = objShell.NameSpace(strZipFile).Items
        objShell.NameSpace(strFolder).CopyHere colItems, 8
        Sleep 5000,strFolder,intCount + colItems.Count
    End Function        

    function controller(path,filesCountMust)
       dim stat:stat=False
       set fold = objFso.getFolder(path)
       set files = fold.files
       if filesCountMust=files.count then
          stat=True
       end if
       set files = nothing 
       set fold = nothing
       controller=stat
    end function

    Sub Sleep(intSeconds,path,filesCountMust)
        dblSeconds = intSeconds / 1000
        If dblSeconds < 1 Then dblSeconds = 1
        dteStart = Now()
        dteEnd = DateAdd("s", dblSeconds, dteStart)  
        do While dteEnd>=Now()
           if dteEnd=Now() then
              if controller(path,filesCountMust)=true then 
                 exit do
              else
                 Sleep intSeconds,path,filesCountMust
              end if
           end if
        loop
    End Sub

    Set objShell = Nothing
    Set objFso   = Nothing

I haven't tried it, but given that I found this this Stack Overflow question and github solution in the same search result. I thought this might be a good shot as a solution to your problem.

This line is the problem

if dteEnd=Now() then

Only if dteEnd is exactly the same as Now() (to the millisecond) will it be able to step into the controller section and head towards the exit do, it doesn't and goes into a recursive loop (back into the sleep function)

Try this instead:

do While dteEnd>=Now()
   if dteEnd>=Now() then
      if controller(path,filesCountMust)=true then 
         exit do
      else
         Sleep intSeconds,path,filesCountMust
      end if
   end if
loop
