It is occasionally useful to direct the F# compiler to use a .NET struct (value type) representation for small, generally immutable objects. You can do this by adding a Struct attribute to a class type, here defined with explicit values and an explicit constructor: [<Struct>] type Vector2DStruct = val dx: float val dy: float new(dx,dy) = {dx=dx; dy=dy} member v.DX = v.dx member v.DY = v.dy member v.Length = sqrt(v.dx * v.dx + v.dy * v.dy) Or you can use a delimited form: type Vector2DStructUsingKeywords = struct val dx: float val dy: float end Structs are often more efficient, but you should use them with care because the full contents of struct values are frequently copied. The performance characteristics of structs can also change depending on whether you are running on a 32-bit or 64-bit machine. birt upc-a, birt qr code, birt code 39, birt pdf 417, barcode in ms word 2007, free upc barcode font for word add watermark to pdf c# [Solved] How to add watermark image in pdf file - CodeProject

Because this is a callback, the function context is the DOM node that fired the event, not the router object. We retrieve the EventRouter reference that we had attached to the DOM node, using the backing object pattern that we saw earlier. We then call the notify() method of the router, passing the event object in as an argument. The full code for the Event Router object is shown in listing 4.8. var jsEvent=new Array(); jsEvent.EventRouter=function(el,eventType){ this.lsnrs=new Array(); this.el=el; el.eventRouter=this; Occasionally it is necessary to define a new .NET delegate type in F#: type ControlEventHandler = delegate of int -> bool This is usually required only when using C code from F#, because some magic performed by the .NET Common Language Runtime lets you marshal a delegate value as a C function pointer. We ll take a look at interoperating with C and COM in 17. For example, here s how you add a new handler to the Win32 Ctrl+C handling API: el[eventType]=jsEvent.EventRouter.callback; } jsEvent.EventRouter.prototype.addListener=function(lsnr){ this.lsnrs.append(lsnr,true); } jsEvent.EventRouter.prototype.removeListener=function(lsnr){ this.lsnrs.remove(lsnr); } jsEvent.EventRouter.prototype.notify=function(e){ var lsnrs=this.lsnrs; for(var i=0;i<lsnrs.length;i++){ var lsnr=lsnrs[i]; lsnr.call(this,e); } } jsEvent.EventRouter.callback=function(event){ var e=event || window.event; var router=this.eventRouter; router.notify(e) } add watermark image to pdf using itextsharp c# Adding Image watermark to Pdf while Creating it using C# – reader ...

If you know a function s name, you do not have to use the Insert Function dialog box. You can simply do the following: 1. Select the desired worksheet cell. 2. Type an equals sign. 3. Type the function s name. 4. Type an opening parenthesis. 5. Type values for any function arguments separated by commas. 6. Type a closing parenthesis. 7. Press the Enter key. open System.Runtime.InteropServices let ctrlSignal = ref false [<DllImport("kernel32.dll")>] extern void SetConsoleCtrlHandler(ControlEventHandler callback,bool add) let ctrlEventHandler = new ControlEventHandler(fun i -> SetConsoleCtrlHandler(ctrlEventHandler,true) ctrlSignal := true; true) Note that some of the methods of the array are not standard JavaScript but have been defined by our extended array definition, which is discussed in appendix B. Notably, addListener() and removeListener() are simple to implement using the append() and remove() methods. Listener functions are invoked using the Function.call() method, whose first argument is the function context, and subsequent arguments (in this case the event) are passed through to the callee.

You do this using a notation similar to discriminated unions: type Vowels = | A = 1 | E = 5 | I = 9 | O = 15 | U = 21 This type is compiled as a .NET enum, whose underlying bit representation is a simple integer. } function drawThumbnail(e){ cursor.style.left=((e.clientX/5)-2)+"px"; cursor.style.top=((e.clientY/5)-2)+"px"; } </script> </head> <body> <div class='mousemat' id='mousemat'></div> <div class='thumbnail' id='thumbnail'> <div class='cursor' id='cursor'/> </div> </body> </html> add watermark to pdf using itextsharp c# Add Watermark in PDF in C# , VB.NET - E-iceblue
