you could also use

buyerName.Contains(TextBox3.Text)
buyerName.BeginsWith(TextBox3.Text)
buyerName.EndsWith(TextBox3.Text)

are you asking as the interviewer or interviewee?

you can't decrypt this. This is a one-way hash. It is the best way to handle passwords. You don't want to be able to decrypt them.

sounds like homework. Show us what you have tried and then we can help

return "";

select the info that you want into a datatable,
set the datatable as the datasource for the dropdown. call the databind function. and make sure you specify in the dropdown control which columns...

do you mean how to passs it to a function or how to write a function that accepts it?

function that takes one would look like this

private void test(char[,] b)
{
//do whatever here
}

that login code will leave you open to an sql injection attack. Never take input directly from an input and put it directly into an sql query

int intTemp = Convert.ToInt32(Console.Readline())

select * from tablename where Cast(columnName as VarBinary) = Cast(@input as VarBinary)

well thanks for posting that so I didn't waste my time

other than the missing semicolon at the end of

e = true


this compiles and runs fine for me

kinda hard to tell, but what happens with your first example if there is an exception during someAction()

1) what are you trying to do? Add an option for every column in every table in your database?

2) again, what exactly are you trying to do, what have you tried? Are you trying to add all the...

what you probably want to use is a gridview (or datagrid, if your are not on 2.0) and bind it to the database

where are you getting the items that you put in the listbox? a config file? dataset?

what system? and search for what?

use +=

str1="1";
str2="0";
str1+=str2; //str1 is now "10"
str1+=str2; //str1 is now "100"
str1+=str2; //str1 is now "1000"

I don't really get what you are trying to do.
the way you have it, textbox 1 should have "10" in it and
textbox two should have "10^1" in it.

What are you wanting to have in the two boxes?

are all your licenses going to start with "LIC-" if so why not just put that part in a label outside the text box and only put the variable part of the license in the text box. Like when you see a...

you load the whole file and parse through it every time someone submits a word?
wouldn't it be better to load the list once when the program starts up?

yeah, sorry you need using System.Text also

actually you don't want to be able to decrypt it.

what you do is encrypt the password and save that in the database

when the user logs in, encrypt the password the input on the login screen...

you're missing the point, which is that you're sql query isn't going to work.
It is always going to return either null or "admin"

here, let me clean up your code so that it more cleanly does what you have it doing now

publicstring FuncAuthentication(string txtusername)
{
return "admin";
}

LabelName.Text = StringName;

sorry, bub, but that makes no sense because:
1) how is Page.IsValid supposed to know if the user is in your database
2) if you do already know that the user is valid, what is the point of this...

Here's a hint, what happens if your query returns 0 rows?

well sure, if you want to do it the easy way ;)

create a class called appointment with the appropriate fields.
create an array of appointments using your existing pc.xml
read in the new one and compare each new one to the ones in your array.
...

actually, I'm not 100% sure what was wrong with it the 1st time. it shouldn't even compile the way you had it listed.

try this:

if (textBox.Text == "")
labelResult = "Please enter a temperature to convert.";
else{
if (!radiobutton1.Checked && !radiobutton.Checked)
labelResult = "Please select a...

whoops, yeah i was thinking you wanted a string. If you want a datetime, go with first reply.

if you are sure those are the only 3 formats the date will be in, you can do this:

string strDate;

//pseudocode
// strDate = date from database

if(strDate.Length>8)
strDate=...

don't know if it will help or not, by I wrote a Sudoku Solver program in C# if you are interested

looks right to me. It also looks like you caught that you were counting 2 twice. Very good.

Also, minor detail but
if(IsPrime == true)
is kind of redundant
you can just use
if(IsPrime)

it won't work, because it is going to say the number is prime the first time it finds a number that it is not divisible by.

set the bool IsPrime to true, then go through the inner loop, if you...

Hi,
We don't mind helping with homework, we just hate when someone does absolutely nothing and just wants someone to do their homework for them.
What you posted is fine.

A couple of hints to...

no problem

here, same result in 4 lines

private void SongTitle()
{
char[] strArray = SelectedFile.ToCharArray();
string result; = new string(strArray);
