i selected tiles and also tried with large icons in the same menu.but images are not visible..

Ican't attach a screen shot here.there is no location to attach..please i f anyone got my question answer me..

In System.Version I couldnt find features to validate version number with the above one.
Think in to a list Im adding 2.1 but that cannot be entered without 2 already in the list..
How can I do this validation?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{

string v1 = "1.0.1.1";
//string v2 = "1.24.55.487";
string v2 = "1.1.55.487";

var version1 = new Version(v1);
var version2 = new Version(v2);

var result = version1.CompareTo(version2);
if (result <= 0)
Console.WriteLine("version1 is smaller");
else

Console.ReadLine();

}
}
}

//this is wt i tried...

lt is WPF

it is C# 4.0 FRAMEWORK

yes.it is a list box.i have to check the order of list box values according to versioning rules..

This also not working.I dnt knw what to do..my main requirement is getting student ranks accroding to thier marks and view them using crystal report.above query which i used is showing ranks correctly.but i have no idea how can i view them through crystal reports.because it can't insert to db.without above formula,if there is another method which i can calculate ranks through crysatal report please show me the way.

Yes.Iam sorry that i have put wrong tag.iam using mysql.

above is the method which iam using..by giving those 4 parameters i want to add data.how can i do that to same excel without opening again and again?

public void WriteToExcel(string myPath,string row,string col,string val)
{

FileInfo fi = new FileInfo(myPath);
if (!fi.Exists)
{
MessageBox.Show("file doesn't exists!");
}
else
{
var excelApp = new Microsoft.Office.Interop.Excel.Application();
var workbook = excelApp.Workbooks.Open(myPath);


Excel.Worksheet worksheet;

worksheet = (Excel.Worksheet)workbook.Sheets.get_Item(1);

((Excel.Range)worksheet.Cells[row, col]).Value2 = val;

excelApp.Visible = true;





//workbook.Save();
workbook.Close();


}
}

now it works..but there is another problem when i use this method to write several data to same excel.i want to add several data to a same excel which is exsiting.but when i tried it it always open excel sheet foe each time when i call this method..is there any method to close the excel like excel.close or something?

I tried this code..but it gives following error for " Microsoft.Office.Interop.Excel.Range range = worksheet.Cells[1,1] as Range;"
this line..
nullreferenceunhandled..
