I need to make a process notify another process of some event.

For simple example,

Application A have a textbox and [Send] button.

Application B have a Label.

Enter some text in the textbox and enter [Send] button from Application A, then that input text should be displayed from the Application B.

How could I do this?

Use one of the IPC methods (Interprocess Communications),

like WM_COPYDATA
