I got so used to it, I can't turn it off. Another great yet simple idea! Made with .NET 3.5 Just thought I might share this with you all!

Tiny Pad is much lighter on the system. I really like the archiving feature. The highlighting and the firefox-like search are real key features. What's a real bummer is that there's no tagging like OrangeNote. I heard the next version will work on Unix/Mac. Thanks for sharing! access calender database from mobile S.M.

Color Palette From an Image Arun Jacob18-Feb-09 19:03 Arun Jacob 18-Feb-09 19:03  How to Generate a color palette from an image? Just like, http://kuler.adobe.com/#create/fromanimage Check the above link for demo. How to do that in .NET? Any Ideas? Thanks in Advance. Arun Jacob My Blog Re: Color Palette From an Image Dave Kreskowiak19-Feb-09 4:39 Dave Kreskowiak 19-Feb-09 4:39  All you do is call GetPixel on a Bitmap object to return the color at a specific location in the image.

But GetPixel is for getting pixel from a particular (x,y) in the image. We can iterate through the image and we can findout all the colors in the image by using that. But i have to analyse the whole image and need to find only few colors which are unique in the image,but not the whole colors. So i think some complex logic will be there for analysing only unique colors. I tried some logics.But i think may be some good logics there for finding it out. Any ideas 4 that? Thans in Adavance. Arun Jacob My Blog Re: Color Palette From an Image Dave Kreskowiak20-Feb-09 1:44 Dave Kreskowiak 20-Feb-09 1:44  That makes the problem a bit more clear. In that case, I have no idea. But, I'd probably start by researching histograms to see if they would play any part in the algorithm.

Re: AxWebBrowser Print Functionality Pete O'Hanlon18-Feb-09 4:11 Pete O'Hanlon 18-Feb-09 4:11  What you could do, is use CSS and add items into your page that only get shown by a print version of your CSS.

Sorry i didnt mentioned it in my original post.. in my windows application , i have embeded the axwebbrowser and placed one button. On click of that button i am calling the below method public void PrintBrowser() { object o = ""; // constants useful when printing SHDocVw.OLECMDID Print = SHDocVw.OLECMDID.OLECMDID_PRINT; // use this value to print with prompting SHDocVw.OLECMDEXECOPT PromptUser = SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_PROMPTUSER; //SHDocVw.OLECMDEXECOPT DontPromptUser = //SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER; if (!IsPrinterEnabled()) return; // print with prompting user //axWebBrowser1.ExecWB(Print, DontPromptUser, ref o, ref o); // to prompt the user with printer settings axWebBrowser.ExecWB(Print, PromptUser, ref o, ref o); } This method prompts the print dialog using ExecWB(..) method and prints the content of the web browser alone . My question is i need to add some header and footer text and also some extra texts to the content of the browser content. Can u help me out to solve thsi problem. Thanks.

Rob Philpott18-Feb-09 5:09 Rob Philpott 18-Feb-09 5:09  More of a C# man myself, but the classes you'll be interested in are HttpWebRequest and HttpWebResponse. Create the former, set its verb to POST, and write your xml to the stream. I think its in the System.Net assembly. Regards, Rob Philpott. Choosing between Remoting, WCF or TCP Listeners xandytsui17-Feb-09 19:08 xandytsui 17-Feb-09 19:08  Last November, I was trying to do a multi client program for a Question And Answer game, the game is like this: 1. The judge (ok, this is a real people) ask a question, and then on his Master Terminal (computer-server), he click "start answer" 2. Then the participants (real people) on their own computer, can click "answer", if they want to answer that question. 3. Master terminal will show all intended participants, and the fastest one will "Flash" on both Master terminal screen and the Client screen. 4. Master terminal can also set the score and the score will be shown on (participants)client screens. I tried to implement this with remoting at that time. But I found a couple of problems when I am implementing that. First, what I have in my mind is for remoting, the application code should not realize that they are calling remote objects or local objects, this should be done by the transparent proxy objects. It is definitely achievable without any problem when creating remote objects, calling methods of that particular objects, but when it comes to events and delegates, it is a different story. I have to make the client expose to another port to listen the event fired from remote objects, and moreover, another dummy object have to be declared in-between the remote object and the client application. (see the method shown here: http://www.codeproject.com/KB/IP/RemotingEvent.aspx?msg=2821954[^]) The use of intermediate object totally breaks the beauty of transparent proxy, and make the code became messy. So, my question here is, in doing such project, am I using the wrong technology? Should I use WCF or the old school TCP Port listener? modified on Wednesday, February 18, 2009 7:41 PM Re: Remoting, WCF or Old school method Dave Kreskowiak18-Feb-09 5:11 Dave Kreskowiak 18-Feb-09 5:11  xandy1979 wrote: Should I use WCF or the old school TCP Port listener?
