System.OutOfMemoryException in June 2010 build

[GoogleCodeExporter]

Hello!

This error is only thrown having run my application for a few minutes. It 
doesn't happen straight away. Here's the stack trace:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' 
was thrown.

   at SlimDX.ObjectTable.Add(ComObject comObject, ComObject owner)

   at MyClass.MeasureString(ChartFont f, String text) in J:\root\CanvasDirect2D.cs:line 1039

My methods look like this:
    public override System.Drawing.SizeF MeasureString(ChartFont f, string text)
    {
      this.Font = f;
      SlimDX.DirectWrite.TextLayout layout = TextLayout(text);
      SlimDX.DirectWrite.TextMetrics metrics = layout.Metrics;
      return new SizeF(metrics.WidthIncludingTrailingWhitespace, metrics.Height);
    }

    private SlimDX.DirectWrite.TextLayout TextLayout(string text)
    {
      if (this.dwfactory == null)
      {
        this.dwfactory = new SlimDX.DirectWrite.Factory(SlimDX.DirectWrite.FactoryType.Shared);
      }
      SlimDX.DirectWrite.TextLayout result = new SlimDX.DirectWrite.TextLayout(dwfactory, text, TextFormat(), XCenter * 2, YCenter * 2);
      return result;
    }

Nothing special here. 

Thank you!

I presume you call MeasureString (and thus TextLayout) in a loop somewhere?

If so, the memory leak is caused by the fact that you never Dispose() of the 
Factory or TextLayout objects you allocate. SlimDX objects do not finalize 
themselves, so you're leaking all the native resources that underpin the SlimDX 
objects. This behavior is documented in the Object Lifetimes section of the 
Programming Guide in the SDK Documentation.
