    Question give focus to another window

    Hi,

    Somebody please let me know how and which api should i use

    When your application gains or loses focus Windows sends the WM_ACTIVATEAPP message, the wParam will then contain the activation flag, TRUE if your application gains focus in which case lParam will contain the thread identifier of the thread that owns the window that is losing focus.

    No, cause I'm not using VB.Net. In classic VB you would subclass your form and check for the WM_ACTIVATEAPP message.
