how to validate combobox values with testdata values

[Saket]

You can try this

Code:

Set fso=createObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(YourFilePath, 1)
Dim strLine, arrLine, bMatch
if f.AtEndOfStream <> True
            strLine = f.ReadLine
            arrLine = split(strLine,",")
end if

val=window("").wincombobox("").getitemscount

bMatch = 0
for i= 0 to val-1
    d=window("").wincombobox("").getitem(i)
    if d = arrLine(i) Then bMatch = 1
Next

If bMatch = 1 then
    Msgbox "Compare - Failed"
Else
    Msgbox "Compare - Passed"
End if

I am assuming you have values in the text file in the form "Val1,Val2,.."
let me know if it works..
