In the contact information, touch the e-mail address of the contact you d like to use. You'll see that the Mail program launches automatically with the contact s name in the To: field of the e-mail. Type and send the message.

The effect in figure 14.15 was accomplished by defining a DrawingBrush, setting its TileMode to Tile, ViewPortUnits to Absolute, and the ViewPort to 0,0,16,16 . We then set the Drawing of the DrawingBrush to the ImageDrawing of the magnifying glass.

Next to the Information button you will find the Picture/Object button. Touch this button to insert media, tables, charts, or shapes into the document. When you first touch this button, you will see the Media tab highlighted and all your photo albums visible. To choose a photo, navigate through the available albums and select the corresponding photo to use. To add a table to the document, touch the Table tab and choose from the various table formats shown.

For example, if we need to call the GetForecastedSet shared method located in the RsLibrary class (AWC.RS.Library assembly) from an expression or embedded code, we would use the following syntax:

Helper class Text Description Checks string-related constraints Methods Contains(string) EndsWith(string) StartsWith(string) Like(string) List Checks collection-related constraints Count(constraint) Element(int, constraint) Equal(IEnumerable) IsIn(object) OneOf(IEnumerable) Is Checks the direct value of parameters passed in Anything() Equal(object) GreaterThan(IComparable) LessThan(IComparable) Matching<T>(Predicate<T>) NotNull() Same(object) TypeOf(Type) Property Checks the value of a specific property on an object that s passed in as a parameter IsNull() Value(Type, PropertyName, object) ValueConstraint(Type, PropertyName, constraint)

can't be used with static Red = new Color(255, 0, 0); Green = new Color(0, 255, 0); Blue = new Color(0, 0, 255);

objShell.Run("sqlcmd -S<STANDBYINSTANCENAME> -E & strDatabaseName & ".sql & strDatabaseName & "-results.txt")

Execute ./configure. Open config.status, look for file path names split over more than one line (around line 310), make each into a single line, and save the file. Execute ./config.status (doing so generates correct makefiles). Execute the make command.

One solution is to use reference (or ref) parameters so you can modify the values of the parameters passed into the member function: // error using System; class Point { public Point(int x, int y) { this.x = x; this.y = y; } // get both values in one function call public void GetPoint(ref int x, ref int y) { x = this.x; y = this.y; } int x; int y; } class Test { public static void Main() { Point myPoint = new Point(10, 15); int x; int y; // illegal myPoint.GetPoint(ref x, ref y); Console.WriteLine("myPoint({0}, {1})", x, y); } } In this code, the parameters have been declared using the ref keyword, as has the call to the function. This code should work; however, when compiled, it generates an error message that says that uninitialized values were used for the ref parameters x and y. This means variables were passed into the function before having their values set, and the compiler won t allow the values of uninitialized variables to be exposed. You have two ways to get around this. The first is to initialize the variables when they re declared:

After demonstrating that the implementation you provide for the basic query operators doesn t have to work on generic types, we ll show you in a third example that your implementation doesn t necessarily have to work on sequences either.
