1. What is the problem ? Just create in array in "User" class and give get/set property to it. Then you can use it also from Main.
2. Get a random number, add it in an array. Next time if you get random number, compare it to that array, if number exists, then get new one.

Ok..after that how will make the random class generate numbers maximum of 6 numbers?
ex. 10, 36, 12, 1, 38, 21

I just give you a hint :
I will not do the homework for you.

See No. 2 how to avoid creating double random number.

To create 6 random number, just use :

Random random = new Random();
int myNumber = random.Next();

Just call random.Next() 6 times.

How to add a toolbar using windows forms programming of c#

http://msdn.microsoft.com/en-us/library/system.windows.forms.toolstrip.aspx[^]

I just created a brand new site, it's called Google. It's neat, give it a try! Smile | :)

Google: C# toolbar[^]

If i want to run code at runtime from string (Something simple)
How can i do it?

for example , i want something that does "operateThisString" function :

public int X
      {
          //Some Expression
          get { return this.Y * this.Z; }
      }

      public int Y
      {
          //Some Expression
          get { return (int)((Math.Sin(new Random() * 10))*52); }
      }

      private void button1_Click(object sender, EventArgs e)
      {

          string codeExpressionThatReturnInt = "return (this.X*this.Y%2);";
          int numbber = operateThisString(codeExpressionThatReturnInt);
          if (number == 0)
              MessageBox.Show("This number is Even.");
          else if(number==1)
              MessageBox.Show("This number is Odd.");
      }

the string codeExpression can come from the user in some way.
What is the simplest way to do it?

Using Reflection.Emit to Precompile Expressions to MSIL[^]

The MSScriptControl - that would allow you to run JavaScript/VBScript dynamically. The good news is that there are lots of articles on this subject.

The bad news is that it's "old", and you'd prolly want to offer the user VB.NET or C# to extend the application. That means offering an editor, embedding the compiler, and loading the generated assembly during runtime.

This[^] article would get you started on the first technique, this[^] article if you go for the second option.

Can you please give me an exmaple how to do it?

The two links that I posted point to examples, with explanation;

MSScriptControl example is here[^], the other example is here[^].

Ha! The article I submitted yesterday might help with that. Big Grin | :-D

Or try this[^] --

int X = 2 ;
int Y = 3 ;
 
PIEBALD.Types.Rational r = PIEBALD.Types.Rational.ParseInfix ( string.Format
(
    "{0}*{1}%2"
,
    X
,
    Y
) ) ;

Then test for zero.

Hi,

my datatable contains the following columns...
resultsView.Columns.Add("Fam.", typeof(string));
resultsView.Columns.Add("Component", typeof(int));
resultsView.Columns.Add("Description", typeof(string));
resultsView.Columns.Add("Quantity", typeof(double));
resultsView.Columns.Add("Unit", typeof(string));
resultsView.Columns.Add("Unit Price", typeof(double));
resultsView.Columns.Add("Total", typeof(double));

i have a datatable,
I use IEqualityComparer to get distinct rows.
Im able to get the distinct rows...
What my problem is If i find same rows, i need to increase a columnValue in this datatable.

I mean i have column named "component" in my datatable, so if two rows are same, then i need to get one row with component value increased by 1 using IEqualitycomparer. What i get now is only one row with component column value not increased...

cud anyone plz help me to solve this problem??

I have a main form 'customerForm' with a button which creates a child window 'customerPrintForm' containing a listView. So:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace DebtManagement
{
    public partial class DiaryPrintForm : Form
    {
        private ListViewSortManager m_sortMgr;

                               typeof(ListViewTextSort)
                           },
                4, System.Windows.Forms.SortOrder.Descending);
                    
                }
                if (diaryListView.SelectedItems.Count == 0 && diaryListView.Items.Count > 0)
                {
                    diaryListView.Items[0].Selected = true;
                }
            }
        }
    }
}

However, the listView is not populating as expected (the rows are empty), although if I run my mouse over the expected date column a tooltip appears with the correct data.

Can anyone here see why this sould be please?
