GetManifestResourceStream Memory Leak ?

Hi All,

I have a graphic on screen that I load from an embedded resource.

Under certain conditions I want this icon to flash - so I have two
icons that I switch between using a timer (this fires every half a
second)... the code just loads a different bitmap from a resource and
sets the PictureBox.Image as required.

This all works fine except for one issue - the amount of free memory on
the PDA seems to keep dropping continuously until over 1MB has been
used up.. then seems to stop. The GIF image I'm loading is only 8Kb.

By elimination (i.e. commenting it everything except one line) I've
traced the problem to the actual GetManifestResourceStream call.

Any suggestions are welcome as memory is a precious commodity on PDAs!!

The code is as follows (I've tried to be very explicit about closing
and destroying everything )

Public Sub ChangeHighlightForSelectedIcon(ByRef oCurrentPictureBox As
PictureBox, _
ByVal eHighlightState As
enumHighlightState, _
ByVal
eCurrentScreenSettings As enumScreenSettings)

:

oCurrentAssembly = [Assembly].GetExecutingAssembly()
oBitmapStream =
oCurrentAssembly.GetManifestResourceStream(ROOT_NAMESPACE & "." &
sNewBMPIcon)

'Load bitmap from stream.
oTempIcon = New Bitmap(oBitmapStream)

If oCurrentPictureBox.Image IsNot Nothing Then
oCurrentPictureBox.Image.Dispose()
oCurrentPictureBox.Image = Nothing
End If

oCurrentPictureBox.Image = CType(oTempIcon.Clone, Image)
oCurrentPictureBox.Refresh()

Catch ex As Exception
'Required if bitmap does no exist as an embedded resource.
Finally
If oBitmapStream IsNot Nothing Then
oBitmapStream.Flush()
oBitmapStream.Close()
oBitmapStream = Nothing
End If

If oTempIcon IsNot Nothing Then
oTempIcon.Dispose()
oTempIcon = Nothing
End If

If oCurrentAssembly IsNot Nothing Then
oCurrentAssembly = Nothing
End If

sNewBMPIcon = Nothing
End Try
End Sub
