You can simply have the Load event of the main form instantiate and show a secondary form:

// in load event of main form
SecondForm f = new SecondForm();
f.Show();

Open in new window

If you want to make sure your new form to stay on top of the other form, you might want to use .ShowDialog()

The code is almost the same as mentioned above:

FormReminders frmReminders = new FormReminders();
frmReminders.ShowDialog();

My bad, I intended to use preview...

An example of a basic class:

public partial class frmMainForm : Form {
  public frmIudexnet() {
    InitializeComponent();

    //You call your second form here (asuming you already created you form with the IDE)
    FormName frm = new FormName();
    frm.ShowDialog();
  }

Open in new window

Hi,

Sorry I should have been a bit more specfic, I want the second form (reminders) to load and be displayed top left for example but first form to be displayed in the middle on the screen and focus on the first form

Thanks for the help so far

Thanks,

In that case you should use this for your second form (after InitializeComponent()):

frmSecondForm.Show();

Open in new window

You can set the position using your Form-properties in your IDE: StartPosition: manual. After that you can set your location property to 0; 0

after calling the new form you can use:

this.TopMost = true;

Open in new window

that should keep your first form on top
