[loops] How do I read a file line by line in VB Script?

I have the following to read a file line by line:

wscript.echo "BEGIN"

filePath = WScript.Arguments(0)
filePath = "C:\Temp\vblist.txt"
Set ObjFso = CreateObject("Scripting.FileSystemObject")
Set ObjFile = ObjFso.OpenTextFile(filePath)
StrData = ObjFile.ReadLine
wscript.echo "END OF FIRST PART"

Do Until StrData = EOF(ObjFile.ReadLine)
    wscript.echo StrData
    StrData = ObjFile.ReadLine
Loop

wscript.echo "END"

The EOF() function doesn't seem to work:

C:\Users\EGr\Documents\Scripts\VB>cscript testloop.vbs ArgVal
Microsoft (R) Windows Script Host Version 5.8

BEGIN
END OF FIRST PART
C:\Users\EGr\Documents\Scripts\VB\testloop.vbs(11, 1) Microsoft VBScript runti
me error: Type mismatch: 'EOF'

I haven't programmed in VB before, but I'm trying to figure out loops so that I can modify a VB script I've been handed. I want to read a file line by line, and do something with each line. If I change the Do Until loop to Do Until StrData = EOF, it works but throws an error when it gets to the end of the file:

C:\Users\EGr\Documents\Scripts\VB>cscript testloop.vbs ThisRANDOMValue
Microsoft (R) Windows Script Host Version 5.8
Copyright (C) Microsoft Corporation. All rights reserved.

BEGIN
1
END OF FIRST PART
host1
host2
host3
C:\Users\EGr\Documents\Scripts\VB\testloop.vbs(13, 2) Microsoft VBScript runti
me error: Input past end of file

I feel like there is probably an easy solution, but I haven't been able to find it. I've tried a few other solutions I've found online, but haven't got as close as the above.

If anyone like me is searching to read only a specific line, example only line 18 here is the code:

filename = "C:\log.log"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

For i = 1 to 17
    f.ReadLine
Next

strLine = f.ReadLine
Wscript.Echo strLine

f.Close
