In addition, if you want to set up arbitrary location you can use this

FormLoading frm = new FormLoading();
Point location = new Point(300, 400);
frm.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
frm.Location = location;
frm.ShowDialog();

Answer 2

NewForm.Show();

NewForm.Top = (this.Top + (this.Height / 2)) - NewForm.Height / 2;
NewForm.Left = (this.Left + (this.Width / 2)) - NewForm.Width / 2;

Answer 3

You might want to check the Form.StartPosition property.

http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition.aspx

something along the lines of:

private void OpenForm(Form parent)
{
    FormLoading frm = new FormLoading();
    frm.Parent = parent;
    frm.StartPosition = FormStartPosition.CenterParent;
    frm.ShowDialog();
}

This of course requires setting the form's parent.

Answer 4

form1.StartPosition = FormStartPosition.CenterScreen;

See http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition(v=vs.110).aspx

if you are making a custom MessageBox,you can simply put this:

CenterToParent();

in your custom MessageBox formload() method.
