  Hi;
  
  I didn't write a test case but from this it should be easy for you to do so. With 1 thread, no problem. With 2+ threads (my unit test has 16), always get the exception.
  
  I was able to avoid the exception with the following code - by wrapping it in the snychronized. text is usually a single character like "T".
  
  

  private static final float MAX_RECT = 100000;

  private System.Drawing.RectangleF getCharRect(String text, System.Drawing.Font font)
  {
  synchronized (ParaFormatterDotNet.class)
  {
  System.Drawing.RectangleF rect = new System.Drawing.RectangleF(0, 0, MAX_RECT, MAX_RECT);
  System.Drawing.StringFormat fmt = createStringFormat();
  fmt.SetMeasurableCharacterRanges(new System.Drawing.CharacterRange[] { new System.Drawing.CharacterRange(0, text.length()) });
  System.Drawing.Region[] rgns = graphics.MeasureCharacterRanges(text, font, rect, fmt);
  return rgns[0].GetBounds(graphics);
  }
  }
  
  

  private System.Drawing.StringFormat createStringFormat()
  {
  System.Drawing.StringFormat fmt = System.Drawing.StringFormat.get_GenericTypographic();
  fmt.set_Trimming(System.Drawing.StringTrimming.None);
  fmt.set_FormatFlags(System.Drawing.StringFormatFlags.MeasureTrailingSpaces | System.Drawing.StringFormatFlags.NoWrap);
  return fmt;
  }

  Hi;
  
  It's buried deep in the Windward Reports engine and only occurs in one specific test case.
  
  One thing of note, the test case is when I start 10 threads that all hammer my reporting engine at the same time. So I have several threads all making this call at once. And my system has dual processors so 2 threads are actually running at the same time.
  
  My code is 100% managed code so theoriticly this exception should be impossible.
  
  thanks - dave

  Hi,
       If you can provide us a brief repro that isolates this problem, we should be able to debug it for you.
       Since this problem seems to be more specific to .NET, you can also try posting the access violation on the .NET forum (http://ddweb/answerme/questions.aspx forumID=39).
