Well I think no matter what you are not going to be able to stop very motivated repeat voters. Even major democractic elections using physical voting machines and verified official IDs still run into voter fraud and they've been doing it for years!
However there are probably measures you can take to stem fraud to a minimum. Your first task is to make sure scripts can't vote, only people...so definitely use a CAPTCHA. Also have the user enter an email address with a unique link embedded inside, so they need to check their email and click on a link to make the vote count. This wont stop people with multiple emails voting, but you could also look into doing some simple data mining after the vote takes place to notice any glaring issues...like if there are 10 votes in 10 minutes from the same IP.
Another critical note: whatever this voting system is going to elect, it better not be important! Because if it is, someone motivated enough will probably be able to crack, or at least bias, whatever system you have in place.
Good luck!

Any particular reason you're not using a gridview?
|
|
|
|
|
You have used Controls.Add method everywhere. Use
TableRow.Cells.Add([New Control]") method appropriately.
Ex:
tr.Cells.Add(tc1);
tb1.Rows.Add(tr);
I have tried it and its working 
|

You can use GridView instead of creating your own. Compared to your own table gridview is a wise control.

Hi all,
Iam using a grid in my web application..
I want to move the row up if i Click the up button and move a row down in down button
How can i do using javascripts??i got the rowindex
var grid=igtbl_getGridById("grid");
var actrow=grid.getActiveRow();
var rowindex=actrow.getIndex();
using this rowindex how can i move the row to up or down..
can anyone suggest me?
if any other way also suggest me.

One Idea ...! Add a button in grid's footer row so that it will raise RowCommand Event.
From there try this,
if(e.CommandName.Equals("Button1"))
{
if(GridView1.SelectedIndex != -1 && GridView1.SelectedIndex < GridView1.Rows.Count )
{
GridView1.SelectedIndex = GridView1.SelectedIndex +1;
}
}
it will work

i have the following controls dropdownlist1,dropdownlist2,textbox1,button1,button2,dropdownlist3
and
textbox2
i want to show the data of above controls into textbox2
through the corresponding controls event only

Make all event handlers call the same method, generate a string in this method and pass the string to the text property of textbox2

Hi,
I am working with Visual Web Developer 2005(c#.net).
I want to pass more than 15 parameters to a function.
So,for clarity i wrote the function in multiple line using the operator "& _".
But,it doesn't work and i get an error message as 'The name '_' doesn't exist in the current context.
Can anybody help me in this?.
|
|
|
|
|
'& _' can be used only with VB.NET.
Use '+' to concatenate strings in C#
|
|
|
|
|
in vb.net there is no End of the line character ";" so if you want to break a single line into 2 you have to use "-". In C# we have ";", so we can split a line into 2.
Ex:
Response.Write
(
"Hi, Like this"
);
|
|
|
|
|
//you can use like this also
Response.Write("hi,"+path+"");

objIncidentBL.UpdateIncidentDetails(Convert.ToInt32(txtIncidentNo.ToString()),
txtApplicationName.ToString(),
txtIncidentType.ToString());
I have to pass 15 more parameters in this function.if i use '+' as below,i m getting an error message such as operator '+' cannot be applied to operand of type string.
objIncidentBL.UpdateIncidentDetails(Convert.ToInt32(txtIncidentNo.ToString()), +
txtApplicationName.ToString(), +
txtIncidentType.ToString());

LazhiniP is true.Remove "+" it will work fine.
|
|
|
|
|
No...if i remove '+' it gets compiled but i m throws a run-time error stating "input string is not in correct format".
Whether '+' operator doesn't work for parameter passing or in function definition?
Yazhini
|
|
|
|
|
if you think the problem is with "+"
Response.Write("First" + "Second"
+ "Third"
);
Try this
