[Solved] How to open one window and close another on button click [closed]

by


Let’s say you have a main form. Call it frmMain.
In frmMain before IntializeComponent

frmLogin loginForm = new frmLogin();
//Set the dialog result on login form depending on ok and cancel button

//close the application if user wants to cancel
if(loginForm.DialogResult == DialogResult.Cancel)
   this.Close();

//else you can continue to call your frmMain initializeComponent method
