Please forgive me if i dont explain this situation correctly. i'll try
to do my best.
because the arraylist.add method only accepts one argument, i created
an object with several public properties.
AddElement.vb (compiled and saved in Bin folder)
' VB Document
Imports System
Namespace myArrayObject
Public Class AddElement
Private _pName as String
Private _pType as String
Private _pSize as Integer
Public Property pName as String
Get
Return _pName
End Get
Set
_pName = Value
End Set
End Property
Public Property pType as String
Get
Return _pType
End Get
Set
_pType = Value
End Set
End Property
Public Property pSize as Integer
Get
Return _pSize
End Get
Set
_pSize = Value
End Set
End Property
End Class
End Namespace
Then I imported this object into a codebehind file. my goal was to
instiate the object's properties and set them accordingly
dbArraylist.vb (codebehind file with command event sub)
Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Web.UI.HTMLControls
Imports myArrayObject
Imports System.Collections
Imports System.Data
Imports System.Data.SqlClient
Imports dbComponent
public class myALComponent
Inherits Page
Protected WithEvents lkID as linkbutton, lblAnswer as label
sub getActivityList(s as Object, e as CommandEventArgs)
Dim ID As Int32 = Int32.Parse(e.CommandArgument)
Dim myArrayList as new ArrayList, myParameter as new AddElement,
objItem as object
myParameter.pName = "@ID"
myParameter.pType = "ID"
myParameter.pSize = 0
myArrayList.add(myParameter)
myParameter.pName = "@ID2"
myParameter.pType = "ID2"
myParameter.pSize = 2
myArrayList.add(myParameter)
response.write("<br>myArrayList Count : "& myArrayList.count &
"<br>")
for each objItem in myArrayList
response.write("<br>AL : <br><li>" & objItem.toString)
next
end sub
end class
the aspx file passes the commandName and commandargument (= 1) via a
linkbutton. ive tested the link and it works, but im not using the
commandargument yet. my obstacle now is retreiving the property values
stored inside the object inside the arraylist. right now, i get
'myArrayObject.AddElement' as the objItem in myArrayList. that makes
sense because that is the object inside the arraylist. but, i want to
get the pName(string), pType(string) and pSize(integer) which are
public properties of the AddElement object from the
myArrayList(elementNumber). i tried casting it toString (result :
myArrayObject.Addelement) and cType(myArrayList(0), string) result :
can not cast error. thx for the help in advance.
