"Do" not recognised at start of loop in VBScript

Question

So, I'm doing this watch program. I have a loop that I use to continuously update time. But for some reason, the system doesn't recognise the Do at start of loop. It is in a while loop, if that changes anything. I also put a On Error Resume Next but still get error message. Is this linked? Help would be greatly appreciated. Here's source code:

On Error Resume Next

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
        & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set ie = CreateObject("InternetExplorer.Application")
ie.Navigate "about:blank"

While ie.ReadyState <> 4 : WScript.Sleep 100 : Wend

    ie.ToolBar   = False
    ie.StatusBar = False
    ie.Width     = 200
    ie.Height    = 250

    ie.document.body.innerHTML = "<p id='msg'>0</p>"

    Set style = ie.document.CreateStyleSheet
    style.AddRule "p", "text-align: center;"

    ie.Visible = True

    Do
        Set colItems = objWMIService.ExecQuery("Select * from Win32_LocalTime")

        If objItem.DayOfWeek = 1 Then
            day_name = "Monday"
        Else If objItem.DayOfWeek = 2 Then
            day_name = "Tuesday"
        Else If objItem.DayOfWeek = 3 Then
            day_name = "Wednesday"
        Else If objItem.DayOfWeek = 4 Then
            day_name = "Thursday"
        Else If objItem.DayOfWeek = 5 Then
            day_name = "Friday"
        Else If objItem.DayOfWeek = 6 Then
            day_name = "Saturday"
        Else
            day_name = "Sunday"
        End If

        For Each objItem In colItems
            ie.document.getElementById("msg").innerText = "Date:" & vbCrLf & day_name & vbCrLf & objItem.Day & "/" & objItem.Month & "/" & objItem.Year & vbCrLf & vbCrLf & "Time:" & vbCrLf & objItem.Hour & " : " & objItem.Minute & " : " & objItem.Second
        Next
    Loop

While End

Answer 1

The issue is you have an extra Wend on your outer While statement so the While End expects a Do (While End is not valid syntax in VBScript).

Remove Wend from this line;

While ie.ReadyState <> 4 : WScript.Sleep 100

and change While End to Wend.

Once that issue is fixed you will have another problem as your inner Do statement loop has no way to exit and will continue infinitely unless you supply a condition that will allow it to exit either by specifying While or Until or by using Exit Do.

Summary

This might not be what you want but it will stop that specific error. The problem is without guessing what your intention was it is difficult to refactor the code without changing your intent (but it looks like @Hackoo has done it). Would recommend you take a look at the links provided to the VBScript documentation that details how the While and Do loops should be used.

Answer 2

Note : You have some syntax mistakes here : You should write ElseIf instead of Else If

And in the last line While End to Wend

In your question you want to continuously update the time; so you can do it with Do ..Loop statement with a Timeout of 1 second inside with Wscript.sleep 1000
