Hi
I am using C# 2008 with Access 2007. I am using MDI on MDI a added a menu now that Menu have a Login MenuItem which is enable and other menu items are disabled at form load. Now I am try to implement this if login is successful then other menu items will be enabled automatically. I tried lots of technique but I can't able to access Menu Items from Login Form. What I tried here is the code - I just want to activate the deactivated menus after valid login and deactivate the login menu.

namespace EzBuddy

{

    public partial class UserLoginForm : Form

    {

        //public NewUser nuser1;

        private OleDbDataReader aReader;

        private OleDbCommand aCommand;

        private OleDbConnection aConnection;

        public int login_flag = 0;

        public UserLoginForm()

        {

            InitializeComponent();

        }

        public void menuEnable()

        {

           

        }

        public void login_code()

        {

            int x = LoginBox.TextLength;

            if (x < 5 || LoginBox.Text.Equals(""))

            {

                MessageBox.Show("ID is of minimum 5 digits as your Permanent Emplolee code or 9 digits as your Temporary Employee code", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

                LoginBox.Text = "";

                PasswordBox.Text = "";

                LoginBox.Focus();

            }

            try

            {

                database_Connection();

                aReader = aCommand.ExecuteReader();

               

                while (aReader.Read())

                {

                    if (aReader.GetString(0).Equals(LoginBox.Text) && aReader.GetString(1).Equals(PasswordBox.Text))

                    {

                         login_flag = 1;

                        break;

                    }

                    else

                    {

                        login_flag = 0;

                    }

                }

                if (login_flag == 1)

                {

                     

                    [B]MDIParentForm.loginToolStripMenuItem1.Enabled = false;

                    MDIParentForm.newToolStripMenuItem3.Enabled = true;

Ok well I assume you declare the MDIParentForm form somewhere right? Like:

Form1 MDIParentForm = new Form1(); 

If you do then goto the menuStrip(no such thing as menuBar ;) ) and in every menuItem of the menuStrip you need access to, change the property of modifier from "private" to "Public", that should do it for you. Also i think the link in my signature may help you.

EDIT: Heres the Link: C#, Working With Information Across Forms.

Good luck ~ Committed.

Tnax for your consideration. I already changed the modifier property to public still I am getting error -
"Error 1 'EzBuddy.MDIParentForm' does not contain a definition for 'loginToolStripMenuItem1' C:\Documents and Settings\Vishal\My Documents\Visual Studio 2008\Projects\EzBuddy\EzBuddy\UserLoginForm.cs 60 35 EzBuddy"Above error is for MDIParentForm.loginToolStripMenuItem1.Enabled = false; shown in the code in previous post

Hmm, try double clicking on the 'loginToolStripMenuItem1', and let it create an event for it. Hopefully the compiler will recognize it then.

Look at your UserLoginFor designer.cs file and make sure that "loginToolStripMenuItem1" is declared. If it's not in there, that would be the reason for your issue. (I think) ;)

Yeah im pretty sure thats the problem also, thats why I said create an event for it so it should declare it.
