Ensure that a TextBox caret is visible

Setting a multiline TextBox's SelStart property doesn't ensure that the insertion point (the caret) is visible. You can achieve this by sending the control an appropriate message:


Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal _
    hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _
    lParam As Any) As Long
Const EM_SCROLLCARET = &HB7

' Ensures that the caret is visible.

Sub ScrollCaret(tb As TextBox)
    SendMessage tb.hwnd, EM_SCROLLCARET, 0, ByVal 0&
End Sub
