    This is a very simple mail sending program for windows. POP has not been implemented yet, so some branches might not do anything useful

    Here is a small application I made using the Google web service. You can search for something and it will search the Google database and return the number of results. I'm going to have it bring up your web browser and display the results soon.

    This was my first C# application. It is also a web service that takes two numbers and sends them to my server. The operation is performed and the value is returned back to the GUI. I'm not sure if I still have the service running so let me know if it doesn't work.

    My latest application. I can't post any code or exes on this because I did it for work but I'll explain it. I had finished working on an application written in Java just a week or so ago. In the application I had an XML file that served as a bunch of strings used throughout my application. So if anyone wanted to make any changes they would open the XML file and make them (SMTPHost, Email Subjects, about 45 other strings). Of course this leaves room for errors. Someone not thinking could erase an element tag or something and screw up the whole application. So I decided to make an admin tool for modifying the XML file. It is a Windows Form that has a label and a textbox for each element in the XML file. Also it has tabs to separate each group. The user starts the application (the admin tool) and selects parse from the menu. The application parses my XML document and fills in the textboxes with the element data from the file. They can make changes to the document and save it. The application will then write the XML document back with the new values. The Java application parses the XML every time it starts so if the XML has changed, it takes effect the next time the Java app starts. Pretty cool, huh?

    Hm... this programs are cool, but they are very slow. What's the point of the C# language?
    Current projects:
    1) User Interface Development Kit (C++)
    2) HTML SDK (C++)
    3) Classes (C++)
    4) INI Editor (Delphi)

    How do you define slow ? The first one runs like a charm on my notebook. The point of C# is directly accessing the .NET Framework for easy to build but powerful GUI applications.

    They're web services. Information is going across the Internet. When you factor in my cable modem and whatever kind of connection you are on, it is going to be slow.

    Yeah, the Google one is fast because the web service is being hosted at Google's servers. The second one is slow because it is hosted at my house.
