    VC++ SendMessage API to VB6 Application

    Hi folks,

    I write a small tool to SendMessage with LB_ADDSTRING to a listbox in VB6 application. New item has successfully inserted into target listbox. But characters become ????. What's wrong with this?

    The string must exist in the context of VB6 app process. But when you send the message, the string exists in "a small tool" process but not in VB6 app.
    Best regards,
