This approach allows to create a collection in two-dimensional array. Thus, each entry in the collection contains several items. I have this all over the framework for years. This has proven to work exceptionnally well so far. So, basically, as the entry in a collection can have multiple types, I have object. So, when the collection is built, it builds up an object and store it in the collection. So, I can scan the collection for the name that I am looking for. Then, I can extract any property I want from it.

The situation that happened an hour ago seems to be related to this:

"By using weak references, cached objects can be resurrected easily if needed or they can be released by garbage collection when there is memory pressure."

So, that would explain why oImage collection had been released from memory because of a memory pressure. As this one is called within an intensive approach, an array seems to be more appropriate for storing about 20 items in that collection.

For your information, this is how the collection is built:

        ' If this is the Web site
        If oApp.nApplicationMode = 3 Then

            ' If we have some images in memory
            If oApp.oAdmin.oRow("Image").length > 0 Then

                ' Load the application into the string builder
                loStringBuilderFile.LoadString(oApp.oAdmin.oRow("Image"))

                ' For each image
                For lnCounter = 1 To loStringBuilderFile.nLine

                    ' Get the line
                    If Not loStringBuilderFile.MLine(lnCounter) Then
                        Return False
                    End If

                    lcImage = loStringBuilderFile.cLine

                    ' If the file exists
                    If oApp.FileExist(oApp.cGraphicFat + lcImage) Then

                        ' Get the image details making it OK to reender the HTML without flickering
                        loImage = New System.Drawing.Bitmap(oApp.cGraphicFat + lcImage)
                        lnWidth = loImage.Width
                        lnHeight = loImage.Height

                        AddImage(lcImage, lnWidth, lnHeight)
                    Else
                        AddError(oApp.cGraphicFat + lcImage + " does not exist.")
                    End If

                Next

            End If

        End If

...and the AddImage() method:

    ' Add an image in the collection
    ' expC1 Name
    ' expN1 Width
    ' expN2 Height
    Private Function AddImage(ByVal tcName As String, ByVal tnWidth As Integer, _
     ByVal tnHeight As Integer) As Boolean
        Dim lcExtension As String = ""
        Dim lcName As String = ""
        Dim lnLocation As Integer = 0
        Dim loObject(4) As Object

        ' Initializaiton
        lcName = Trim(tcName)
        lnLocation = oApp.At(".", lcName)

        ' If we have found it
        If lnLocation > 0 Then

            ' If this is not the last character
            If lnLocation < lcName.Length Then
                lcExtension = Mid(lcName, lnLocation + 1)
            End If

        End If

        ' Initialization
        loObject(1) = lcName
        loObject(2) = tnWidth
        loObject(3) = tnHeight
        loObject(4) = lcExtension

        oApp.oImage.Add(loObject)

        Return True
    End Function
