i am creating this 2 forms

form A - login

form B - personal info list

firstly user gotta key in its username and password for verification.

i used switch-case to do the comparing of the password and to verify different password range stands for different user.after verification is successful,form B will appear to request user to key in information.

the tricky part is different user will be able to access certain parts of the form B.

how am i suppose to let form B know that form A current user log in is 1 or 2 or 3

so that it is possible to enable different controls?

Form A

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace PasswordTest

public partial class Form1 : Form

public Form1()

private int logonAttemptCount = 0;

int intAccessCode;

Main frm = new Main();

private void okButton_Click(object sender, EventArgs e)

intAccessCode = Int32.Parse(passwordTextBox.Text);

if (usernameTextBox.Text == "level1")

switch (intAccessCode)

case 0:

case 1:

case 2:

case 3:

case 4:

case 5:

case 6:

case 7:

case 8:

case 9:

statusLabel.Text = "Restricted Access";

MessageBox.Show("Sorry,Please Try Again.Invalid");

if (logonAttemptCount == 3)

MessageBox.Show("Too many logon attempts. Exiting Application.");

this.Close();

break;

case 0101:

case 1111:

statusLabel.Text = "Scientists";

break;

case 2222:

case 3333:

statusLabel.Text = "Custodians";

break;

default:

statusLabel.Text = "Access Denied";

MessageBox.Show("Sorry,Please Try Again.Invalid");

usernameTextBox.Text = "";

passwordTextBox.Text = "";

if (logonAttemptCount == 3)

MessageBox.Show("Too many logon attempts. Exiting Application.");

if (usernameTextBox.Text == "level2")

switch (intAccessCode)

case 6666:

MessageBox.Show("Welcome.Accountant");

usernameTextBox.Text = "";

passwordTextBox.Text = "";

break;

case 8888:

case 9999:

statusLabel.Text = "Managers";

MessageBox.Show("Welcome.Manager");

usernameTextBox.Text = "";

passwordTextBox.Text = "";

break;

else

usernameTextBox.Text = "";

passwordTextBox.Text = "";

statusLabel.Text = "Access Invaild";

MessageBox.Show("Sorry,Please Try Again.Invalid");

if (logonAttemptCount == 3)

this.Close();

private void cancelButton_Click(object sender, EventArgs e)

this.Close();

You can create a property in the Form B, something like this

public partial class Main : Form
{
public Main()
{
InitializeComponent();
}

private void Main_Load(object sender, EventArgs e)
{
switch (this.username)
{
case ...
......
}
}

private string username;

public string UserName
{
get { return this.username; }
set { this.username = value; }
}
}

before showing the form Main form, set UserName for it..

In Form A:

Main frm = new Main();
.....
frm.UserName = this.textBox1.Text;
frm.Show();

You can create a property in the Form B, something like this

public partial class Main : Form
{
public Main()
{
InitializeComponent();
}

private void Main_Load(object sender, EventArgs e)
{
switch (this.username)
{
case ...
......
}
}

private string username;

public string UserName
{
get { return this.username; }
set { this.username = value; }
}
}

before showing the form Main form, set UserName for it..

In Form A:

Main frm = new Main();
.....
frm.UserName = this.textBox1.Text;
frm.Show();

hi sorry but to check i tried applying the code stated but while building it right the terms i declare under the switch case is not available

is there any error in my switch case?

private void Main_Load(object sender, EventArgs e)

switch (this.username)

case Scientists:

radioButton1.Enabled = false;

radioButton1.Checked = true;

radioButton2.Enabled = false;

radioButton3.Enabled = false;

radioButton6.Enabled = false;

break;

case Custodians:

radioButton1.Enabled = false;

radioButton1.Checked = false;

radioButton2.Enabled = true;

radioButton3.Enabled = false;

radioButton6.Enabled = false;

break;

case Accountant:

radioButton1.Enabled = true;

radioButton1.Checked = false;

radioButton2.Enabled = false;

radioButton3.Enabled = false;

radioButton6.Enabled = false;

break;

case Managers:

radioButton1.Enabled = false;

radioButton2.Enabled = false;

radioButton3.Enabled = false;

radioButton6.Enabled = false;

break;

Set a breakpoint at switch (this.username) to see what the username is, does it matches any of your usernames?

the program cant run as they state that "Scientist" doesnt exist in the context for the for B and this eror applies to the rest like managers and all.

its either they are able to locate or did i lack out of any declaring?

thanks

obviously you do not define the Scientists,Custodians....

meaning define it in form B?

#define scientist?

or string scientist

Hi

Your using Scientist as if it were a declared object e.g string Scientist = "Scientist" or Scientist MyScientist = new Scientist()

But seen as though your comparing a string, you just need to wrap it in quotes at the case statement.

e.g case "Scientists":

Cheers

Si

thanks(: solved cheers
