private Bitmap rotateImage(Bitmap b, float angle)
{
  //create a new empty bitmap to hold rotated image
  Bitmap returnBitmap = new Bitmap(b.Width, b.Height);
  //make a graphics object from the empty bitmap
  Graphics g = Graphics.FromImage(returnBitmap);
  //move rotation point to center of image
  g.TranslateTransform((float)b.Width/2, (float)b.Height / 2);
  //rotate
  g.RotateTransform(angle);
  //move image back
  g.TranslateTransform(-(float)b.Width/2,-(float)b.Height / 2);
  //draw passed in image onto graphics object
  g.DrawImage(b, new Point(0, 0));

}

Must have semi-colon on last statement before the "WITH" keyword that begins the Common Table Expression (see sample below on "select @Dummy = 0;" line).  Multiple CTE's must be comma delimited under the single "WITH" keyword (i.e. only the first CTE begins with the "WITH" statement, the subsequent ones begin with a comma).

declare

  @BegDate datetime

, @EndDate datetime

, @Dummy int

select

  @BegDate ='2/1/2009'

, @EndDate ='2/28/2009 11:59PM'

select @Dummy = 0;-- Prepare for the WITH CTE statement

with HistoryMax(ModificationID, HistoryDate)as

(

  select ModificationID,max(HistoryDate) HistoryDate

  from LMM.TermsHistory

  where HistoryDate <= @EndDate

  groupby ModificationID

  and h.HistoryDate = hm.HistoryDate

When using a select statement to set a variable, and the select statement returns multiple rows, the last row returned will be the value stored in the variable. You can use sorting or a TOP statement to change this behaviour (as shown in samples below).
 

createtable #tmp(val int) 

insertinto #tmp values(1)
insertinto #tmp values(2)
insertinto #tmp values(3)
insertinto #tmp values(4)
insertinto #tmp values(5) 

declare @val int

selecttop 1 @val = val
from #tmp
orderby val asc select @val /* returns 1 */ 

select @val = val
from #tmp
orderby val asc select @val /* returns 5 */ 

select @val = val
from #tmp
orderby val desc select @val /* returns 1 */ 

droptable #tmp

private IQueryable<ClientInfo> OrderBy(IQueryable obj){

  ParameterExpression param = Expression.Parameter(typeof(ClientInfo), string.Empty);

  MemberExpression property = Expression.PropertyOrField(param, this.SortExpressionLabel.Text);  

  LambdaExpression sort = Expression.Lambda(property, param); 

  string methodName = "OrderBy"; 

  if (SortDirectionLabel.Text == "DESC")  methodName += "Descending"; 

  MethodCallExpression call = Expression.Call(typeof(Queryable), methodName, new[] { typeof(ClientInfo), property.Type },      obj.Expression, Expression.Quote(sort)); 

  return obj.Provider.CreateQuery<ClientInfo>(call);
