In the following code the text will not display if I use the
stringFormat in the Drawstring and will separate the two strings if I
do not use the stringFormat:

graph = e.Graphics;
pen = new Pen(Color.Black,2);

//graph.DrawLine( pen,100,100,200,100);
drawFont = new System.Drawing.Font("Arial", 8, FontStyle.Bold);
drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.Black);

String sTest = "MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM";
Region[] stringRegions = new Region[1];
StringFormat stringFormat = new StringFormat();
stringFormat = StringFormat.GenericDefault;
stringFormat.Trimming = System.Drawing.StringTrimming.Character;
stringFormat.FormatFlags += 16384;
//graph.TextRenderingHint = TextRenderingHint.AntiAlias;
CharacterRange[] characterRanges = new CharacterRange[1];
characterRanges[0] = new CharacterRange(0,sTest.Length);
stringFormat.SetMeasurableCharacterRanges(characterRanges);
stringRegions = graph.MeasureCharacterRanges( sTest, drawFont,
this.ClientRectangle, stringFormat);
RectangleF rect = stringRegions[0].GetBounds(graph);
//rect.Offset(10,10);
//graph.DrawString(sTest,drawFont,drawBrush,rect);
graph.DrawString(sTest,drawFont,drawBrush,rect,stringFormat);
rect.Offset(rect.Width,0);
//graph.DrawString(sTest,drawFont,drawBrush,rect);
graph.DrawString(sTest,drawFont,drawBrush,rect,stringFormat);

Please help
