outofmemoryexception was unhandled with pictures

[djpaul]

Hello,
For my neighbour i am creating a photoalbum.
But when i load more then 110 photo's in a flowlayoutpanel with pictureboxes i get the error outofmemoryexce ption was unhandled.
Do i need to resize the picture before loading them or can i do something else?

This is my code for loading:

Dim Table As DataTable
        Dim i As Integer

        FlowLayoutPanel1.Controls.Clear()

        Dim SQL As String = "SELECT fotonaam, fotomap, textveld FROM foto WHERE (fotomap = '" & Replace(CmbPath.Text, "'", "''") & "');"

        Table = SelectQuery(SQL)
        Dim ThumbPicturearr(Table.Rows.Count) As PictureBox


        While Table.Rows.Count <> i

            ThumbPicturearr(i) = New PictureBox
            ThumbPicturearr(i).Name = "Foto" & i
            ThumbPicturearr(i).Height = 134
            ThumbPicturearr(i).Width = 164
            ThumbPicturearr(i).BackColor = Color.DarkGray
            ThumbPicturearr(i).Image = Image.FromFile(Table.Rows(i).Item("fotomap") & "\" & Table.Rows(i).Item("fotonaam"))
            ThumbPicturearr(i).SizeMode = PictureBoxSizeMode.Zoom
            ThumbPicturearr(i).BorderStyle = BorderStyle.Fixed3D

            FlowLayoutPanel1.Controls.Add(ThumbPicturearr(i))
            i = i + 1

        End While
        Table.Dispose()

since you have the while and end while, thats probably what runs out of memory, try creating a new thread with the actions to perform and set the threadname.isba ckground property to true

Hmm, that doesn't seems like no sense to me for using another method for the while.
Okay, i tried:

For i = 0  To Table.Rows.count

'stuff

Next i

But same error occures.
And what did you mean by the isbackground property? the ThumbPictureArr ?

like create a new thread, to the addressof a sub that performs the actions you want, in your case either the

For i = 0  To Table.Rows.count

'stuff

Next i

method or the previous one. umm the .isbackground property is a property of a thread so example

    Dim mythread As Threading.Thread = New Threading.Thread(AddressOf backgroundactionsthread)
    Private Sub subonmainthread()
        mythread.IsBackground = True
        mythread.Start()
    End Sub
    Private Sub backgroundactionsthread()
        For i = 0 To Table.Rows.count

            'stuff

        Next i
    End Sub

so move the code inside the "subonmainthrea d" sub to wherever, such as on a button click event or wherever it suits you, pretty simple...tell me if you need more help...

*Threads are dangerous for beginners, please be sure to make sure that your threads close properly, when either in debugging or built already...but they arent too bad...(threads close automatically when events/actions are accomplished...
