Hi Rajveer,
Please make dictionary as static at the top ,remove it from button click code.This will caluse increment of value.
Dictionary dictionary = new Dictionary();

Regarding validuser -Check user id -is it hardcoded or reading from somewhere.

Hi Rajveer,

Please find the below code snippet.
//create a static variable on top
public static int value=0;

.//button click code
string user=txtUser.Text;

Dictionary dictionary = new Dictionary();
if(value !=3)
{
if (validUser)
{
MDIParent1 m = new MDIParent1();
m.Show();
this.Close();
}
else
{
if (dictionary.ContainsKey(user))
{
value = dictionary[user];
value=value+1;
dictionary[user]=value;
}
else
{value=value+1;
dictionary.Add(user, value);
}
MessageBox.Show("Invalid user name or password. Please try with another user name or password", "DRRS", MessageBoxButtons.OK, MessageBoxIcon.Warning);
txtUsername.Focus();}
}
}
else
{
MessageBox.Show("Sorry you have tried to access application either with wrong user name or wrong password! Sorry for the trouble!", "DRRS", MessageBoxButtons.OK, MessageBoxIcon.Warning);
txtUsername.Focus();
//add blocking code here
}
This is just a sample code snippet.
If the above solution is helpful then,accept the answer.

Just declare a single variable and initialize it with 0. lets say
int count=0 ;

when users enters the wrong id, increments it
if(id is wrong){
count++;
}

if count is greater than or equals 3, disable the application and reset the counter.
if(count>=0){
count=0;
DisableApplcation();
}
