[Solved] Show “Wait” message while performing an action [closed]

by


Add a new form into your project and write Wait on it, and then show that form whenever you need to show wait message to user.

For example your new form name is PopUp. Create its instance before that method, and dispose it later:

if (puntos_rectangulos_estereotaxia.Count == 4)
{
    PopUp popup = new PopUp(); //create instance
    popup.Show(); //display popup

    generar_puntos_rectangulo_por_imagen(); //This takes 5 seconds

    popup.Dispose(); //close popup
}

Additional:

You can also update the message shown. Create a method in Popup class:

public void SetMessage(string message)
{
    this.lblMessage.Text = message;
}

Invoke:

if (puntos_rectangulos_estereotaxia.Count == 4)
{
    PopUp popup = new PopUp(); //create instance
    popup.SetMessage("Wait ! It'll take few seconds to complete."); //set message
    popup.Show(); //display popup

    generar_puntos_rectangulo_por_imagen(); //This takes 5 seconds

    popup.Dispose(); //close popup
}
