In a childform I have a step which need to send and recieve some data to/from a external application, and after update some textbox's fields. During this time the childform need to be static waiting from that data, in this time I need to show a progress bar or something similar, such as, a form saying "Loading data...", and after when textboxes are updated this disapear.

The event to send data is a button, in this event I send and recieve data and also need to display some Loading form.

Kind regards!
