Userparameter to count files in a folder

[WernerCD]

This thread has this vbs script

Option Explicit
Dim objFSO, objFolder, FolderName
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
FolderName = Replace(WScript.Arguments(0),"/","\")
Set objFolder = objFSO.GetFolder(FolderName)
WScript.StdOut.Write objFolder.Files.Count
Set objFolder = Nothing
Set objFSO = Nothing
WScript.Quit(0)

for this userparameter

UserParameter=FileCount[*],cscript c:\FileCount.vbs //nologo $1

What would a good variation be to use wildcards in the script? Say I want to count log files in one directory... and error files in another... all files in a third.

I just can't wrap my head around an easy way to do that in one userparameter.

I'd want something like:

key FileCount[c:/Foo/*.log]
key FileCount[c:/Bar/*.error]
key FileCount[c:/FooBar/error.*]
key FileCount[c:/Bax/]
