Hello,

I'm evaluatin V17.3 and try to use the "PropExchange" object, but your example code (from Helpfile) will not work because "New" isn't possble:

Private Sub LoadData()
    Dim pxRead 
As New PropExchange

...

So I tried another way, but also not work...

Dim pxWr As PropExchange
Set pxWr = Xtremesuitecontrols.CreatePropExchange

pxWr.CreateAsXML False, "Test"
If pxWr.Valid Then
pxWr.ExchangeString "Name", "Jack", ""
pxWr.SaveToFile "B:\Test.xml"
End If

The Result is a Type mismatch error.

Hi,

About second argument of ExchangeString: from documentation

Value

Reference to a variable of type String to save data to or to retrieve data from.

So fixed code is

    Dim pxWr As PropExchange    Set pxWr = Xtremesuitecontrols.CreatePropExchange

    Dim refStr As String
    refStr = "Jack"
    
    pxWr.CreateAsXML False, "Test"
    If pxWr.Valid Then
        pxWr.ExchangeString "Name", refStr, ""
        pxWr.SaveToFile "B:\Test.xml"
    End If

about

Dim pxRead As New PropExchange

it is VB.Net

Regards,
