dotnetfactory object in QTP

var_CreateInstance = DotNetFactory.CreateInstance("System.Environment")
msgbox var_CreateInstance.CurrentDirectory

Dim SystemDate , oDate
Set SystemDate = Dotnetfactory.CreateInstance("System.DateTime")
Set oDate = SystemDate.Parse("Fri, 9 Oct 2009")

FormattedDate = oDate.Day & "/" & oDate.Month & "/" & oDate.Year
msgbox FormattedDate

Set SystemDate = Nothing
Set oDate = Nothing The .NET SortedList class provides a hash table with automatically sorted key/value pairs.

The following code creates a SortedList and populates it with some key/value pairs:Set objSortedList = Dotnetfactory.CreateInstance ( "System.Collections.Sortedlist" )

objSortedList.Add "First", "Hello"
objSortedList.Add "Second", ","
objSortedList.Add "Third", "world"
objSortedList.Add "Fourth", "!"

For i = 0 To objSortedList.Count - 1
WScript.Echo objSortedList.GetKey(i) & vbTab & objSortedList.GetByIndex(i)
Next

' this code creates and populates an ArrayList
Set myArrayList = CreateObject( "System.Collections.ArrayList" )
myArrayList.Add "F"
myArrayList.Add "B"
myArrayList.Add "D"
myArrayList.Add "C"
' [1] add the new element to the ArrayList
myArrayList.Add "Z"
' [2] sort the ArrayList
myArrayList.Sort



And how about deleting an element?
In an array you would need to "shift" the elements to fill the gap and then ReDim the array again.
In an ArrayList you would use either myArrayList.Remove "element_value" or myArrayList.RemoveAt "element_index".
