Using Flash, WebService and Client Cookies

In a recent project i converted a .NET/Html login function to a Flash 8 login page.
My Flash first used the WebService and PendingCall to cummicate with the .NET webservice.

It all worked fine, except the fact that the login function uses a client cookie for authentication :P
As I found out, if you set a client cookie in a webservice it can't be accesible from the client.

I did not find any standard way to solve this yet, so i threw the webservice in the "thrash" and made a regular aspx page and used the LoadVars object.

If anyone have a smooth example to solve this please let us know =)

Save bitmap from flash

Using .NET/C# to generate bitmap from Flash 8

*update*
2006-06-20. I added a progress bar to make it more clear what is happening.

I have been searching for cool ways to use flash for creating gallery functions since it's both cool and easy to make great functions. And now when we can generate files on disk it is really usefull!

There are many examples around for this but I did not really find suitable code for me, using .Net/C#, so after messing around a bit i put together a nice solution using a .NET Web service. Please be patient, it will take a few seconds to generate the pixel array and send it to the web service.

Check it out:



The generated image will show in a new window.

Flash

function Generate(obj:MovieClip):Void
{
var pixelarr:Array = new Array()
var bmp:BitmapData = new BitmapData(obj._width, obj._height,false,0xffffff);
var myMatrix:Matrix = new Matrix();
//No positioning
myMatrix.translate(0, 0);
bmp.draw(obj.Picture,myMatrix);

var w:Number = bmp.width;
var h:Number = bmp.height;

for(var a=0; a ‹ h; a++)
{
for(var b=0; b‹w; b++)
{
pixelarr.push(bmp.getPixel32(b, a));
}
}
var wsdlURI = "http://www.2cool2care.com/flash/Service.asmx";
var myWebService:WebService = new mx.services.WebService(wsdlURI+"?WSDL");
var callback1:PendingCall = myWebService.SaveImage(pixelarr.toString(),h,w);
callback1.onResult = function(result)
{
//result is the file name
if(result)
{
getURL("http://www.2cool2care.com/flash/"+result,"_blank");
trace(result);
}
}
callback1.onFault = function(fault)
{
trace("Err: "+fault.faultstring)
}
}

C#

[WebMethod]
public string SaveImage(string Pixels,int Height, int Width)
{
//Create pixel array
String[] PxArr = Pixels.Split(',');
Bitmap MyImage = new Bitmap(Width, Height);
Graphics Gfx = Graphics.FromImage(MyImage);
Gfx.DrawRectangle(new Pen(Color.Red), new Rectangle(0, 0, Width, Height));
int k = 0;
//Loop and paint pixels
for (int i = 0; i ‹ Height; i++)
{
for (int j = 0; j ‹ Width; j++)
{
MyImage.SetPixel(j, i, Color.FromArgb(Convert.ToInt32(PxArr[k])));
k++;
}
}
//Randomize filename and save
Random RandomClass = new Random();
String Filename = RandomClass.Next().ToString() + ".png";
MyImage.Save(Server.MapPath(Filename), System.Drawing.Imaging.ImageFormat.Png);
return Filename;
}

I Hope someone finds this useful!

Take care,

Welcome!

Hi there!

Pretty cool that you found my bog, since it does not really exists.. that's right, i'm writing the first post right this second :)

Nevermind, what the first message really is about is internet radio.
To be more specific; Proton Radio.
These guys are streaming electronica 24/7, and sometimes it is totally awesome. Cool beats, baselines are mixed with well known songs such as Sweet dreams (yes, Eurythmics), and other classic tracs. I really reccomend!

*please note that some times the music suck a bit, but when you hear these remixes it's all worth it!*

Take care,
Rob
