Let us assume you already added some data to gridview via datatable using ;

   1: dataGridView1.DataSource = siparis_tablo_guncel;

So now you know we have a filled up dataGridView.

Now let us assume in the dataGridView1 we want to add images according to the data within the 6th column. So what we first need to do is to create an image column by writing;

   1: DataGridViewImageColumn img = new DataGridViewImageColumn();

   2:  

   3: img.Name = "img";

   4: img.HeaderText = "Image Column";

   5: img.ValuesAreIcons = true;

   6:  

   7: dataGridView1.Columns.Add(img);

Now we have a image column. With the name “img” with the header “Image Column” As you can see in the 5th line I have stated that my images are actually icons. The reason I did this was that I found out that icons take up less space and flickers less. You can if you want change this option as you see fit.

Now let us get cracking and add those images according to the columns;

   1: int number_of_rows = dataGridView1.RowCount;

   2: for (int i = 0; i < number_of_rows; i++)

   3: {

   4:     if (dataGridView1.Rows[i].Cells[6].Value.ToString() == "true")

   5:     {

   6:         Icon image = SUT.Properties.Resources.succcess_icon;

   7:         dataGridView1.Rows[i].Cells["img"].Value = image;

   8:     }

   9:     else

  10:     {

  11:         Icon image = SUT.Properties.Resources.cancel_icon;

  12:         dataGridView1.Rows[i].Cells["img"].Value = image;

  13:     }

  14: }

I hope this has been informative. Please do tell if you see any mistakes and wish to make suggestions.

Have fun!

This one was a little hard. I got lots of help so I decided to post it online since it doesn’t exist on the internet yet… I wonder why….

The simple step by step instruction:

1. sudo yum install git
2. 
   

   git clone --depth 1 git://github.com/joyent/node.git
   

3. cd node
4. git checkout v0.6.2
5. sudo yum install openssl-devel
6. sudo yum install gcc # you can skip this if you already have gcc
7. sudo yum install gcc-c++ # you can skip this if you already have gcc-c++
8. ./configure       [ thank you Ed for the heads up! ]
9. make -j2
10. make install
11. export PATH=$PATH:/usr/local/bin:/usr/local #this is to add usr local to your path wher nodejs was installed
12. sudo visudo
13. Find Defaults secure_path=/sbin:/bin:/usr/sbin:/usr/bin
    go to the end “a” for append, type “:/usr/local/bin”, ESC, “:wq”
14. curl http://npmjs.org/install.sh |sudo sh #installing npm a very good too to install nodejs packages
    P.S. : This step is outdated as of node.js 0.6.3 since node.js 0.6.3 comes out with npm
15. sudo yum install mongodb #installing mongodb
16. #go to the dir where you wish to code and use npm!!
17. npm install mongodb
18. npm install mongoose
19. npm install express
20. npm install coffee-script
21. npm install stylus
22. npm install underscore
23. npm list

I quote :

The most merciful thing In the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace ar.d safety of a new dark age.

I have just started working in RENKO LTD.. I probably mentioned this before. I am quite busy these days so sorry for the lagging updates. I will be posting some new code and ready code reviews. Also since I finished school (yeah baby I got my diploma!!! ) I will also post all my old home works. For now please enjoy the simple slideshow above.

If you come to Ankara, Turkey on a weekday you could probably find me at ;

So please be patient while I upload my old home works.  And please feel free to browse through www.rentech.com.tr a great place to find physics lab equipment in Turkey.

I will be posting my collision detection software (for a 3D world using only one webcam). You will be able to find it on GitHub.

I will like to show my fellow system admins one of the switch’s we are using in the company we work. I think it will make you smile. As you can see the whole thing is a mess and very scary. We are to re-cable the whole thing once I find some time. The switch is actually under power lines.  So lots of interference. Thanks to some miracle the system still works.

I will take a photo of the new version once I fix the whole thing. If I ever find any time. After all I’m the only IT/Software Developer guy throughout the company.

Another photo I wish to share is of my cubicle. Below is my comp and table.

As you can see from the photo I have a nice little corner. The computer is custom made. i7-960 with 6 gigs of ram. The motherboard is true SATA3 so is the hard disk. I very much like my machine. I installed Fedora 15 and Windows 7 64-bit Prof. Dual boot. Very happy over all.

These days I’m writing in Python and C++. So I have been using the new Eclipse IDE. The new Indigo Eclipse is very good. Uses less RAM and less CPU.

For my PHP programs I have been using the new Netbeans 7.0.1. However because of the poor Python support (you have to install a Netbeans 6.8 version plugin which under certain circumstances crashes the whole Netbeans) I really don’t like it. That said the PHP support looks good.

Talking of PHP we moved our http://rentech.com.tr server to Media Temple. They have good service however it really is expensive. I wish they gave a little more RAM without costing an arm and a leg. The whole thing is just too expensive. However the speed is far superior than HostGator which was our previous server host.

I have also moved the whole network to OpenDNS. We were able to stop botnet activity thanks to the switch. It seems one of the computers got infected even though all the PC’s have anti-virus’s. The company was also able to put up some much needed web content filters. Of course now everyone blames the IT guy for the whole thing.

And that is that really. I will probably be buying an Android phone soon. Everything is grand these days. Couldn’t finish my “IP Home Automation Load Balancing” paper yet. I just really didn’t have the time. Was mostly working on my collision software these days.

I may be going back to USA. I really am not sure when it will be happening.

Below you will able to see some pretty pictures I took with my soon to be old phone.

Oh yeah… I wish to ask… Doesn’t it bother you when your door is kicked and you are checked up every so often as if you were in prison? I get really annoyed when my door is opened without a knock these days. I mean. Privacy people!

    Watching the countryside rise and fall like waves ready to hit our steel boat that huffed it self on to the tracks like a beast after good game. The morning cold reminds me of my idiocy of not bringing my jacket. The hot coffee I made 5 o’clock in the morning warms me and assists me to forget my many past mistakes.

    I am on the road to Eskişehir Osmangazi University. A quick drive to the train station [many thanks to my dad here], a fast rail train ride and a bus ride takes me to my destination.

   In the university I will be attending summer courses that I have to take. Probably the last summer course I will ever take.

I will be posting as much photos I can of Eskişehir. It is a beautiful city. Something I really didn’t expect.

I am very busy this summer. I have started a job in RENKO LTD. [www.rentech.com.tr] and also I am working on second home automation based paper with my good teacher Dr.Ali Ziya Alkar. I have some network simulations to do which has proved a little difficult. However I am confident that I will overcome such difficulties.

I have also updated my CV. It now includes my L33T skillz and my pending patent.

I will soon be posting some projects over at https://github.com/ so please fork me!

Please do continue to read me!

Have a nice day!

I have been working on MSP430 for sometime now. It is an TI (Texas Instruments ) chip. Very fun to play with. We are using a MSP430FG461x series experimental board. This little experimental board has all the bells and whistles one may need to create any application from a home automation controller to a simple step-motor driver. TI provides very good documentation for this grown up toy.

Our first lab homework for this baby was :

By using the MSP430 FG4618 Microcontroller, write a program that controls the LED #1, #2,#4.When we perpetually push the two buttons at the right bottom corner of the board, all ofthe LEDs turn on.When we push perpetually one of the buttons, only the LED #4 blinks, the others turn off.When we push no buttons, the LED #1 and #2 blinks complementarily and the LED#4 turnsoff.

My biggest problem with this exercise was to find what led was connected to what port. However in the end I figured it all out.

Below you will find the program :

#include <msp430xG46x.h>

void initPortPins(void);

void main(void)
{
	 WDTCTL=WDTPW + WDTHOLD;
	 initPortPins();
	 while(1) {
	 	if (P1IN == (0x00))
	 	{
			P2OUT |= 0x06;
			P5OUT |= 0x02;
		}
		else if (P1IN == 0x03)
		{
			P2OUT &= 0x00;
			P5OUT &= 0x00;
			P2OUT |= 0x02;
			__delay_cycles (40000);
			P2OUT &= 0x00;
			P2OUT |= 0x04;
			__delay_cycles (40000);
		}
		else
		{
			P2OUT &= 0x00;
			P5OUT &= 0x00;
			__delay_cycles (40000);
			P5OUT |= 0x02;
			__delay_cycles (40000);
		}
	 }
};

void initPortPins(void)
{
  P1DIR = 0x00;	// Set P2.2,1 as outputs
  P5DIR = 0x02; // Set P5.1 as output
  P2DIR = 0x06; // Set P2.1 to 1
};

Now think of connecting your home appliances, your car and your PC to this magnificent gadget. The possibilities do seem limitless. Emotiv seems to have the best learning algorithms available in the consumer electronics world which makes it possible for prospective developers to develop 3rd party applications and interfaces. Just watch the video below! And yes the developer tools can work with Microsoft Visual Studio
