Nice game for software developers :)

Some of you may remember the CRobots game. It is a game in which you program your own robot (in C) and put it to fight against other robots. This game is available in 3D variant and I think it may be very userful to improve your programming skills. Try it from here: http://antru.ru/crobots3d/ I also built my own robot, I named it Kamikadze because all it does is to spin around and shout itself :D Documentation can be found here: http://crobots.deepthought.it/html/manual.html#8 Happy playing!

C# AddIn - Start Debugging and get the running Internet Explorer instance.

I needed to do this (actually I wanted). I was curious if you can obtain an instance of a Internet Explorer which was started in debugging session. Here is a snipet to do this:         _applicationObject.Debugger.Go(false);         SHDocVw.ShellWindowsClass windows = new ShellWindowsClass();         foreach (SHDocVw.InternetExplorer explorer in windows)         {            if (explorer.LocationURL == string.Empty)            {              // this is our guy!              ie = explorer;            }         } Note : this snipet should be added somewhere where you have access to the _applicationObject.

This is the variable which is declared automatically when you create new instance. I suggest you to put it into the exec method of the AddIn:

     public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
     {
        _applicationObject.Debugger.Go(false);
        SHDocVw.ShellWindowsClass windows = new ShellWindowsClass();
        foreach (SHDocVw.InternetExplorer explorer in windows)
        {
           if (explorer.LocationURL == string.Empty)
           {
             // this is our guy!
             ie = explorer;
           }
        }
     }

You also need to add reference to ShDocVw (Microsoft Shell And Automation Library).
Enjoy!

Touchless SDK : Very interesting and promising technology each of you guys should play with :)

I came on this yesterday, I was bored because all the projects I am working on are to some degree "standard". No dev chalenge. I wanted to create, to do something interesting. So I started to browse CodePlex and found this SDK. Overview : Touchless SDK is a software development kit to help developers create applications which can be controlled without the standard peripheral devices (mouse, keyboard and so on). It enable you to create a applications which are controlled without the need to touch anything at all, just gestures in the air. How is this done? Well, I think there was a lot of research on this topic. We already have programs to detect motion from your video camera, why not try to extract information from those motions? This is

exactly what Touchless does. It captures an info from your camera and if it finds something that is known to be marker - it raises events, to which you can subscribe and do something.
The better news is that Touchless is Open Source project and can be obtained from CodePlex for free.
You can also whach a video on Touchless:





I downloaded this SDK and in less than a minute I made a small program which let's you move your cursor with fingers (I still can't find a good enough way to left and right click ;).
I hope I will have enough time this week to post this simple project so you can get deeper with Touchless as it seems promising technology to me.

Limitations:
Well every good thing has drawbacks. Don't get it wrong. Touchless isn't the standard in this area. It has problems (however I think after it is open source a lot of people can work on it and improve it).
So what are the limitations?
First of all - Touchless is very very very sensitive to light and to colors. It is because the way it works. In order to work, you need to specify a "marker". Marker is the thing the program looks for. So if you have a red tape on your finger and define it as marker, you will be able to command your computer with it. But if there is a object with the same color on the screen and this object is about the same size, it may be found as another marker.

The second problem (at least for the sample project I did) is that most web cameras are not sensitive enough. They are (most of them offcourse) with 640 x 480 pixels resolution. If you are about to move your cursor and your screen resolutions is 1280 x 1024 you will be only able to move the cursor 640 pixels horizontally and 480 pixels vertically (this can be software corrected by moving the cursor 3 or 4 pixels on each pixel that comes from the camera but for sensitive operations (resizing, drawing) it will not be good enough.


However I think the things above will be resolved and we will have another great way to use our computers for almost no extra charge.
I do really wish those guys luck and I will definatelly watch how this project goes and even if I can I will help a bit.
I really fell in love with this toy!
