Good Day Sir/Maam,

I know my subject is so confusing, sorry. I'll explain a bit more clear.

If you have winzip or winrar installed on your computer, there will be a menu named "Add to filename.zip" or "Add to filename.rar" when you right click a file.

I want to implement this feature in my project (I am asked by my professor to create a file encrypter application). So I want to have a "Encrypt this File" menu in the "right click" menu.

For starter, if I click the "Encrypt this File", I want the file path of the file to pop up on the message box of my program. How can I go about with this?

Sorry if I my english is really bad.

Thank you in advance.

Good Day Abhijit,

I am aware of that fact. Wink | ;)

I just read this CP article -> http://www.codeproject.com/csharp/appendmenu.asp

However, there is no instruction on how to add an icon for the context menu.

Do you have any idea on how to put an icon on the left of the context menu?

Thanks for the reply.

I have been reading http://www.codeproject.com/csharp/SimpleContextMenu.asp but can't find a way to apply the command to all files (*.*), the instruction there was file type specific.

In my case, I want to allow the user to right click any file type and be able to "encrypt" it.

Thank you!

Hi Veeru,
I guess you want to lock the table for that particular user, not for others, Correct...........

Here is your Answer:

When user enter password, take a count of his attempts. This you will have to do on the Ok button. Whenever he clicks on OK button after supplying the password, the value of Count will increase by 1. Every time you check the value of count.If it is 3 then fire a Update SQL Query to change Unlock value from 1 to 0.

Lets Try this......... Laugh | :laugh:

Hi,

As suggested by other other fellows, have a counter in authentication procedure/routine, count for invalid tries, and if the count reaches 3, change the ULock to 0. You can even add a column for the total number of times the account ws locked in the same column. Just an idea! Smile | :)

I wil just tell u the Procedure to be done.

1.Initailly the default value of ULock will be 1.

2. Declare a variable WrongPwdCount=0;

3.Check the status of the ULock

if ULock==0
Display the Message as " Your account is locked"

else
WrongPwdCount++;

4. if WrongPwdCount==3
Change the ULock=0
else
Do a successful login

Let me know if this works....

Otherwise Let me send a code for the same

Regards

Try This.

SqlConnection con = new SqlConnection("Data Source=;Database=;User Id=;Password=");
SqlCommand cmd;

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
hfCounter.Value = "1";
}
}
protected void btLogin_Click(object sender, EventArgs e)
{
try
{
con.Open();
string xSql="select * from <trackuser> where userid='" + txtUser.Text + "' and pswd='" + txtPswd.Text + "'";
cmd = new SqlCommand(xSql,con);
SqlDataReader rd = cmd.ExecuteReader();
int x = Convert.ToInt32(hfCounter.Value);
if (x == 3)
{
lblMsg.Text = "User Locked....!";
// write your process here. to change the Lock Status from 0 to 1 OR 1 to 0 etc...
}
else
{
if (rd.HasRows != true)
{
x++;
hfCounter.Value = x.ToString();
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}

I would like to know how we can determine whether a function call is resolved at runtime or compile time.

Thanks in Advance

How about using Reflection?

Thanks.

But I would like to find when is the reference resolved really at runtime or compile time. We say a simple function call is resolved at compile time and something complex with inheritance is resolved at run time. How can I really see it or make sure that how its done. Is there any way to find it with reflection libraries. If yes give me some examples.

Thanks a lot

I have a class, ImageLoad which receives a stringPath where I have stored the encrypted images. I would like to know if it is possible to know if the file has been modified before decrypting it? I'm trying to void getting the exception bad data just because someone added a .crip file [file extension I'm using], to the working folder or modified any file extension to .crip and if it happens I get the exception how can I close the application without getting another exception?

Thanks beforehand !

The way I detach databases is by going to sql server, selecting the database I want to detach, left click on it and select task and then detach. If VS2005, the one I use, is open and it is connected to the database I want to detach I close VS2005 and the detach the database.

Hope it help!

Hello,

Good to see you! Smile | :)

Here is the process of doing that in a simple and easy to understand way, originally it is at:

http://www.experts-exchange.com/Microsoft/Development/MS-SQL-Server/Q_22761995.html[^]

i just tried to make it bit easy to understand. Hope this helps!

Use this to check if the database is in use by any process:
SELECT * FROM sysprocesses WHERE dbid = db_id('" + Put_Database_Name_Here + "');

If it returned zero rows, you are set to detach it, if not then use:
string spid;
foreach (DataRow xyz in datatable.Rows)
{
spid = dr["spid"].ToString();
execute: "KILL " + spid;
}

after that, execute
EXEC sp_detach_db @dbname='" + Put_Database_Name_Here + "';

Use (preferably)
ExecuteNonQuery();

Then close the connection.

Regards,

Adeel
