Hi friends!! I m new to C# programming. I wanted to know how to open another from from one form while closing that form and not the application.

i.e. I have a login form, when login is successful then it should show MDI form and close the login form.

I m using this code but its not working

 private void but_loginok_Click(object sender, EventArgs e)
        {
            this.Close();
            MDIopeningpage mdi = new MDIopeningpage();
            mdi.Show();

Shouldn't you close the form after opening the second form? Alternatively hide the first form and then open the second one.

Actually the problem is that i have a login form, and when the user clicks the submit button and if the username and password are same then the login form should close and the MDI for should open. I m not able to do this.

Can u help?

Thank You.

Well if you close a form then it can't run code. So hide the form, open the new form and pass any details if needed and then close the opener.

What Joe is trying to say is do this:

private void but_loginok_Click(object sender, EventArgs e)
{
     MDIopeningpage mdi = new MDIopeningpage();
     mdi.Show();

this.Close(); // move this to the end

}
