Okey in the Program.cs file show your form like this.
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
LoginForm frmLogin = new LoginForm();
frmLogin.ShowDialog();
Application.Run(new MdiForm());
}
And while opening the child form set the mdiparent.

Hello harini,
You can try like, when user successfully logged in, start separate application of Mainmenu form, by using Process.start( mainmenuform.exe /*Application name*/). - Marked As Answer byKira QianMSFT, ModeratorThursday, July 16, 2009 6:49 AM

Hi all!
Thanks a lot it worked :)..I have another query..like i am not using default menu strip for navigating to the child forms,instead i am using some controls like buttons and links for navigating to the child forms and i have placed those controls in the MDI Container . so i want those controls to disappear on link/button click(ie when the child form opens)andreappear when i exit the child form .All this should happen within the MDI or the parent form and no new window should be opened in the taskbar .. |

hey i have a doubt regarding this code
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
LoginForm frmLogin = new LoginForm();
frmLogin.ShowDialog();
Application.Run(new MdiForm());
}
by executing this code the MdiForm is openingjust by clicking the close button of the login form.it is notmaking it compulsory to enter theuserid and password .How do i solve this problem.Should i have to give somethin like environment.exit() in the login form closing event in order to exit the application when the close button (login form ) is clicked.. |

When the user click on the close button of the login form just exit the application. Application.Exit();
private void btnClose_Click(object sender, EventArgs e){ Application.Exit();}

i am not using a close button but using a default close which comes along with Fixed Dialog(Form border style) and apart from that in the submit button of the login form after successful login i have written a code namely (this.close) for the login form to close.which in this case ll close the whole application after successful login. |

On login form set The DialogResult Property of Ok and Close button (like Ok and Cancel) , and change the code as given below.
[STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false);
LoginForm frmLogin = new LoginForm();
DialogResult drResult = frmLogin.ShowDialog();
if (drResult== DialogResult.OK) // If Click on login and validated then open the application.
Application.Run(new MdiForm());
else //If user click on close button on login windows just close the application
Application.Exit();
}
Further don't use Application.Exit() , on close button click event handler , it will be solve ur problem.

Select the button on login Dialog form right click and choose proerty ,in the property window there is a propery name DialogResult contains multiple options set the option -- for cancel button 'Cancel' and OK button 'OK'
After that write click on dialog form and set the properties AcceptButton and CancelButton .

Hi,
When first time application is loaded it is creating an object of MDIParent form, so when you try to open a child window through its menu you use this keyword to assign the child to MDIParent like this
MainForm childForm = new MainForm();
childForm.MdiParent = this;
childForm.Text = "Window " + childFormNumber++;
childForm.Show();
When you try to open a mdichild form from another child form , you should have a MDIParent form object so for this purpose you must define the static varible in MdiParent form.
public static MDIParent ParentMdiForm;
On initialize of MDIParent form assign the object , to the static variable.
public MDIParent()
{
InitializeComponent();
ParentMdiForm = this;
}
Now you are saved MDIParent form object to the static variable, you can open the Mdichild from child from by using the follwing code.
MDIChildFrom childForm = new MDIChildFrom();
childForm.MdiParent = MDIParent.ParentMdiForm;
childForm.Text = "Window child form ";
childForm.Show();
Good Luck. |
