2011-11-22T03:37:00.001-08:00

I was heavily using google reader notes for the past 2-3 years , as they stopped note in reader service I moved to delicious, I am happy with it, but i have tons of bookmark in google reader notes, I want them exported to delicious, luckily google reader settings page has an option to export notes to JSON format,

I created a tool to export this JSON to delicious.

A generic excel file Importer / Reader - Converting Excel rows into Strongly typed entity

2010-05-04T10:21:00.000-07:00

Its my blog post after a long time ,
Its simply a class it can be used to map Excel columns to an entity fields by adding an attribute to the property

Eg: An excel file with two columns Name and Phone Number
Our Entity is


public class ExcelItem
{
[ExcelColumnIndex(Index=0)]
public string Name {get;set;}
[ExcelColumnIndex(Index=1)]
public string Phone {get;set;}
}

To get List <ExcelItem> containg the excel rows, simply

Importer<ExcelItem> _Importer = new Importer<ExcelItem>();
List<ExcelItem> data=_Importer.ParseExcel("FILE PATH", "sheet1");

ExcelImporter.cs


using System;
using System.Collections.Generic;
using System.Linq;
using System.Data.OleDb;
namespace ExcelImporter
{
    //3-may-2010 Priyan R
    public class Importer where T : new()

                con.Open();
                command = new OleDbCommand(query, con);
                reader = command.ExecuteReader();
                while (reader.Read())
                {
                    var entry = new T();
                    foreach (var property in entry.GetType().GetProperties())
                    {
                        var attributes = property.GetCustomAttributes(false);
                        var attribute = property.GetCustomAttributes(false)
                                .Where(p => p.GetType() == typeof(ExcelColumnIndex)).FirstOrDefault(); ;
                        if (attribute != null)
                        {
                            property.SetValue(entry, reader[((ExcelColumnIndex)attribute).Index].ToString(), null);
                        }
                    }
                    ret.Add(entry);
                }


            }
            catch
            {

                }
            }
            return ret;
        }
    }
    public class ExcelColumnIndex : Attribute
    {
        public int Index { get; set; }

ASP.NET Validation Controls - Conditionally validating

2009-11-27T01:46:00.000-08:00

Using the server side Page.Validate() and Client Side Page_ClientValidate() , we can validate a group of controls conditionally. For eg. i just need to validate some fields only when a checkbox is checked. Both Page.Validate() and Page_ClientValidate() allows to pass a validation group , So we group a set of controls with a validation group and calls this validation functions in both client & server side only on the required validation condition

Server Side



protected void btnSubmit_Click(object sender, EventArgs e)
 {
     if(cbValidate.Checked)
     {
         //validate
         Validate("vgSubmit");
     }
     if (!IsValid) return;
     lblMsg.Text = "Passed validation";
 }

ClientSide


        function CheckValidation() {
            var cbValidate = document.getElementById('<%=cbValidate.ClientID %>');
            var flag = true;
            if (cbValidate.checked) {
                if (!Page_ClientValidate("vgSubmit"))
                    flag = false;
            }
            else {
                Page_ClientValidate("vgDummy")
            }                 
            return flag;

URL Rewriting with ASP.NET 3.5 using System.Web.Routing.UrlRoutingModule

2009-09-23T23:56:00.001-07:00

In asp.net 2.0 we used Context.RewritePath() or other URL rewrite modules. With asp.net 3.5 its easy to do. I did it for my blog for better SEO.

Add reference to system.Web.Routing
Add System.Web.Routing.UrlRoutingModule http module to web.config
Implement an IRouteHandler
Registering routes in global.asax

I am going to rewrite blogs/Posts/{BlogPostID}/{*BlogPostTitle}

I implemented a generic IRouteHandler , it will copy url parameters( eg: BlogPostID,BlogPostTitle ) to http context item collection, so i can URL rewrite any page , without modifying IRouteHandler implementation.


using System;
using System.Web;
using System.Web.Routing;
using System.Web.Compilation;
using System.Web.UI;
public class SiteRouteHandler : IRouteHandler
{
  //30 june 2009 Priyan R

  public IHttpHandler GetHttpHandler(RequestContext requestContext)
  {
      Page page;
      page = BuildManager.CreateInstanceFromVirtualPath(PageVirtualPath, typeof(Page)) as Page;
      foreach (var item in requestContext.RouteData.Values)
      {
          HttpContext.Current.Items["qparam." + item.Key] = item.Value;
      }
     return page;
  }
  public string PageVirtualPath { get; set; }
}

In global.asax added

       
       
      routes.Add(
         "BlogPost",
            new Route("Blogs/Posts/{BlogPostID}/{*BlogPostTitle}",
                  new SiteRouteHandler() { PageVirtualPath = "~/Blogs/Details.aspx" })
         );

So in Details.aspx I can read the parameters


Context.Items["qparam.BlogPostID"].ToString()
Context.Items["qparam.BlogPostTitle"].ToString()

Check the code.

My Love Never Dies.......

2009-08-26T05:57:00.000-07:00

Almost all people might have loved someone in their life..To say something about my love..
I have experienced it three times..but still I dont know exactly what this love thig is
..it made me laugh and cry at the same time...still i am in search of love..
its such a feeling inside us for someone..makes us feel alive..and we get crazy about it..
how that happens is beyond my thinking..it just happens..
I had felled into love with three..but that was incomplete..does that make any sense??he he
of course yes..its always valuable and such an ever memorable feeling to me..
My love is true..always..

I still remember those school days..I didnt get to know that I was in love with someone..
those four years she was with me..After I left my school I got to know how much I miss
her in my life..I believe she would have felt the same what I did..But dont know what to say..
sense of responsibility to my family or something else pushed me back to concentrate
in my studies more..and that relationship stopped when I left my 10th std and joined
plus2..slowly I started trying to forget her..after few days I met another girl..
This time I couldnt stop myself from not loving that girl..I started thinking a lot
about her..what a crap!!I started dreaming too..but , she was not thinking like I did..
hell it took me into a helpless situation..but I recovered from it very soon..
she was not meant to be mine..

And the third one..this time ,I was more carefull and had a clear idea about my wish..
she was so close..and I was very comfortable with her..she enjoyed my friendship..
but she was not in love with me..I dont know what went wrong this time..
she was mistaken or me??I didnt force her or anyone..
coz I believe ,every one has the right to choose someone whom they want to love..
we should not compromise in case of love..it has to happen inside us..otherwise no use..
now I am not feeling to love anyone..just because it cant be made..
hopefully everything will come out to be fine..
and one day i will get my real love ..yes ..I am waiting for that..:)

( For this post i am really grateful to my friend Praseetha, She edited my story in a poet style :) )

Finding Total Records / Total Count returned By Object Datasource SelectCountMethod

2009-06-12T00:05:00.000-07:00

Often SelectCountMethod may be int or long so check the type in object datasource Selected event and store the value in ViewState or a variable so it can be used in the page


protected void odSource_Selected(object sender, ObjectDataSourceStatusEventArgs e)
 {
     if (e.ReturnValue.GetType() == typeof(Int32))
     {
         ViewState["TotalCount"] = e.ReturnValue;

I Moved To New VPS Hosting

2009-05-10T02:20:00.000-07:00

I moved my websites to a new VPS hosting.For the last 6 months I was managing my own server. here in my place its not trusty ISP problems/Power/Cable , so I am leaving it.
For the last two weeks I was experimenting running windows in virtual machine inside mosso-rackspace cloud using QEMU, Mosso is great but currently they provide only linux , surely they will come with windows,

Now I am using VPS by http://www.infinitelyvirtual.com/.They are not well known, but I trust them. Their plans are cheap and good, 19.99$ 512mb 10gb space 500 GB monthly data transfer. They are using vmware based virtualization.

Story : Installing WIndows On Mosso RackSpace Cloud With QEMU

2009-05-09T23:12:00.000-07:00

Rack space cloud is a very good service with low price. Good customer support, i always got chat session with customer support very soon. They currently provide Linux cloud server only. I am waiting for windows cloud server.

I installed windows 2003 in QEMU , i was not able to Get the KQEMU accelaration layer working. So performance was really poor,

Installation story (Installing 32 bit windows 2003)....

First i created an ubuntu 8.04.2 LTS (hardy) cloud server.

1. Update package list

apt-get update
apt-get upgrade

2. Install QEMU

apt-get install qemu

2. Install X Server

aptitude install xorg

3. Redirect X Display to our system

This was the one main problem i faced. I 'X' forwarded the display to windows pc running XMing. It was really slow.. It took abt 50-100MB data transfer to show the initial windows loading screen.. Took long time to display the screen.. So it is impossible to install windows in this way.

I found a solution X11 VNC

4. Install X11 VNC

apt-get install x11vnc

apt-get install xvfb

Create password file

x11vnc -storepasswd

5. Start X11 VNC create option (will automatically create a display)

x11vnc -usepw -create

6. Connect to X11 VNC From windows using TightVNC

7. Download windows 2003 ISO ( i used windows 2003 trial)

8. Create QEMU hdd image file

qemu-img create win2003.img 20G

9.Install windows

Run qemu with win 2003 iso as cdrom

qemu -m 256 -boot d -cdrom win2003.iso -hda win2003.img -localtime

Problems faced

32 bit windows 2003 installation stuck at installing devices screen , but on restarting once it worked fine.

NetWorking

I was not able setup TAP network working. I used user mode networking with port forwarding option

I run this to forward 3389 port for remote desktop , and 80 for IIS

qemu -hda win2003.img -m 256 -localtime -net nic,model=rtl8139 -net user -redir tcp:3389::3389 -redir tcp:80::80

Installing 64 bit Windows 2003

The qemu version we get with apt-get will not work with win 2003 64
I got stuck "Starting windows" while installing
http://qemu-forum.ipi.fi/viewtopic.php?f=9&t=4906

I installed QEMU 0.90 from source , we need gcc 3.x for doing that,ubuntu comes with gcc 4.x so install gcc 3.4

sudo apt-get install gcc-3.4 g++-3.4

export CC=gcc-3.4

Download qemu 0.9.0 source , then compile & install

wget http://tx-us.lunar-linux.org/lunar/cache/qemu-0.9.0.tar.gz

tar xzf qemu-0.9.0.tar.gz

cd qemu-0.9.0

./configure
make
make install

I got an error while comiling qemu

Looking for gcc 3.x ./configure: 372: Syntax error: Bad fd number

To fix this edit the ./configure file and change the first line from "#!/bin/sh" to "#!/bin/bash".

Now i was able to install windows 2003 64

qemu-system-x86_64 -m 256 -boot d -cdrom win2003.iso -hda win2003.img -localtime

Installing KQEMU Acceleration Layer

I tried but was not able to get it work

I tried both apt-get kqemu and compiled qemu 0.9.0 and kqemu-1.3 from source,

1st i tried to install with kqemu it got stuck while "starting windows"

Next i tried with -no-kqemu option now 2003 64 installed successfully
After installation i tried with acceleration, initial loading screen came after it screen gone blank.

I installed using

wget http://www.nongnu.org/qemu/kqemu-1.3.0pre11.tar.gz

tar xzf kqemu-1.3.0pre11.tar.gz
cd kqemu-1.3

./configure
make
make install

modprobe kqemu

Installation Experience

Windows 2003 32 bit got stuck while "installing devices" , after restarting it worked fine.

Windows 2003 64 bit installed with not problem

It took 4-5 hours to complete the installation !!!!

Really need great patient to do.. Some steps will take long time with not progress moving.. But may not be stuck.. need waiting...

Windows Experience

Its usable but really slow.. I ran some asp.net sites on that including my home page, its a little bit slow.. but not so bad.
To install .net framework 3.5 it took 1hr!!

Programmers And Mathematics

2009-02-04T02:04:00.000-08:00

I have been coding in various languages for more than 6 years. Till now i havent used much mathematics for programming. From my experience i feel that one can be a very good programmer without a deep knowledge in maths. But i think proficieny in mathematics will be an added advantage for Programmer. With maths we can write many interesting & funny programs easily without any difficulty.

There is good blog post about it by Steve Yegge.

Start With PIC Micro Controller

2008-12-23T12:12:00.000-08:00

This is my little post to start with pic microcontroller,
here we will look into creating a PIC programmer,Creating a test project

Download following tools

ICProg - For loading program into PICMicro
Also download IC-Prog NT/2000 driver from there

http://www.ic-prog.com/

PIC Simulator IDE - We are going to use its basic compiler for the test program

http://www.oshonsoft.com/

Now build the Programmer

In my programmer i changed a little

Pic needs 13.2V in mclr . In circuit you can see a varible resitor in 7812 , I usded two 1N4148 instead of varible resistor to get 13.2V.

I used 2 gates of 74ls05 instead of uln2803, Also i was able to program PIC16F628A in 12V input instead of 15-18V . Its also working in the given 15-18V

Now build the test project to blink an led

I am using PIC16F628A , an led is connected to RB5(pin 11)

Now write the test code

open pic simulator IDE

goto options->Select MicroController->PIC16F628A
goto Tools->Basic Compiler

Write following code

'Set PORTB all output
TRISB = 0x00
loop:
PORTB.5 = 1
WaitMs 1000
PORTB.5 = 0
WaitMs 1000
Goto loop

Now save & compile a hex file will be generated

Load Program Into PIC

Now connect the programmer to the PC
open ic prog ,if u are using 2000/xp or higher goto options->misc->enable 2000/xp driver else error messages will come

Select device as PIC16F628A

Now load the hex file

Set options in right side

Oscilator - intRC I/O
Fuses - tick PWRT,BODEN

See screen shoot

Now in ic-prog command menu->Program all

If you successfully loaded the program to the PIC, Place the loaded PIC in the test circuit

Check! the led will blink every second!

Happy PICing!

My PIC Micro Experiences

2008-12-23T10:40:00.000-08:00

It has been about 2 years that I did anything with Pic micro as I didn't have much time for that. But I did some in 2004-2006. During that time I was searching the net for studying PIC microcontrollers. I collected a lot of information.

So, here I am writing my old experience with Pic micro.

For me coding for Pic micro was not a problem. It took me only a short time to study Pic micro programming in high level languages, I have coded in Oshon Basic, PicBasic,MiKroBasic,MikroC,CCS.

My first problem to start PICing was to get a Pic Programmer . Pic Micro was not available in my area, it was only available in Ernakulum about 100+ km from my home. A ready made PIC Micro Programmer was available at Cochin but it was priced 2500Rs. At that time I couldn’t spent that much money. So I decided started to make one my own. During that time (2004) I was away from home for studying, I used to Come home only once a month. So, it took me about 4 months to build a working PIC Programmer.
In internet I found Mike Prekedo’s Elchepo. I built it but I was not able to make it working. I think I burned a 5-10 PICs. After that I found Oshon soft of Mr Vladmir Soso, There i found

A parellel port based PIC Programmer circuit & software

PIC Simulator IDE - A great PIC simulator with a basic compiler

I could successfully built this programmer and programmed a PIC16F628A,The first one I made was to blink an LED every second.After that I made another simple programmer (a JDM based one) it was a very good one, simple, serial port basedAfter making that programmer PICing became easy for me, but the components available were limited, (i didn't even get 3.2768 MHz crystal!) I made a clock, a water level controller, remote control for Pc. Some other simple ones like Pic with serial port, LCD etc. I am planning to make an embedded web server, but yet not started.

I ended my PICing a long time ago; i wish to start it all over again!

Read my next post on Starting PICing

Happy PICing

T4 (Text Template Transformation Toolkit)

2008-12-18T02:20:00.000-08:00

I read about it month or two ago in Scott Hansel man's Blog. But I didn't try it at that time. Now when I tried it, I found that it is very useful & you can save a lot of time by using it. You can generate code/SQL, anything you want. I have created a Data Access + Stored Procedure generator using it. May be you already know about "code smith". It is a great template generating tool but it's not free. T4 is free, it's already included with VS 2008. we can use it for VS 2005 too by installing an addin. Oleg Sych has an excellent tutorial about T4.

Symantec Backup Exec System Recovery Server Edition

2008-12-03T18:20:00.000-08:00

From my view its a very good backup/disaster recovery tool. We can take full back of system drive(C Drive or system os drive) also can set to take data backups of selected folders.
Can schedule backups for particular time in a week day , can also set to take backup more than once per day .The best thing about it is its ability to restore to dissimilar hardware. So we can recover from a dissaster very quickly. The recovery disk is a very usefull one ,its really a vista bootable cd (like VISTAPE). In the recovery cd there is lot of tools., we can provide drivers, can connect to network(so its possible to restore from network), browse/manage file system, windows command prompt, can do everything as with vistape or bartpe . I have taken system drive backup of an old AMD athlon 3000+ with VIA chipset system and successfully
restored to another hardware (a new laptop with AMD athlon dual core with NVIDIA chipset) . On restore process its asked for lan driver for the new system (can skip this) , i provided the driver path containing the inf and driver files, after restoration i found the network card working fine. The restoration process was very smooth, My sytem drive backup was about 3 gb , it took about 10 minutes to restore. It was a windows 2003 server backup. On booting up restored system as its hardware are different windows 2003 showed detecting and installing hardware process , after that its showed network hardware detecting. Its took about 20 minutes
after that my systm was working fine ... same as like when i took the backup . Total time taken to restore to dissimilar hardware is about 30-40 minutes, look it will save lot of hours when a disaster occur. I also tried successfully to restore to the same hardware , it only took 10 minutes.....

Note: On restoring to dissimilar hardware you may require to activate the windows again.

I Have a personal web site since I was 16. I used http://priyan.tk domain for a long time. I thank u for Tokelau Islands for providing this great .tk domains for free. I didn't updated my site regularly since i first created it. Now i entirely updated my web site. http://www.priyanonnet.com , what i am happy about it is, its served from my room in cochin... see my poor but smart server ....
