[Wandy Tang]

Dear All,

How to pass a collection from a VB Component to an ASP page? I have no clue
the syntax of all.
Many Thanks.

It seems that the collection would be a member of your object.

For Each Thing In yourObject.CollectionClass
Response.Write Thing.Someproperty
Next

Not without knowing the object model of your component!

Here's an example with a commonly known component.


<%
Dim oFSO, oFolder, oCollectionOfSubfolders, ItemInThisCollection
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oFOlder = oFSO.GetFolder("C:\inetpub\wwwroot")
Set oCollectionOfSubfolders = oFolder.Subfolders
For Each ItemInThisCollection in oCollectionOfSubfolders
Response.Write ItemInThisCollection.name & "<br>"
Next
Set oFolder = Nothing
Set oFSO = Nothing
%>

A collection is an object in its own right and as such can be passed back to
ASP as the return form a function.

In the ASP there is no method of declaring a variable to be a collection
unless you use a collection class to wrap the collection object in something
that can be instantiated so generally speaking you won't have any
intellisense for the collection object so you have to call the methods and
properties 'blind'.

eg. VB:
[In myobject class of mydll COM component]

Function GetCollection() as Collection
Set GetCollection = New Collection
End Function

In ASP:
Dim pobjObject
Dim pcolCollection

Set pobjObject = Server.CreateObject("mydll.myobject")
Set pcolCollection = pobjObject.GetCollection()
With pcolCollection
Response.Write "There are " & pcolCollection.Count & " objects in the
collection."
End With

Set pcolCollection = Nothing
Set pobjObject = Nothing
