How you obtain the CheckBox's hWnd is up to you...

Code:

---

Private Const BM_SETCHECK As Long = &HF1

Private Declare Function SetCheckValue Lib "user32.dll" Alias "SendMessageW" (ByVal hWnd As Long, Optional ByVal uMsg As Long = BM_SETCHECK, Optional ByVal Value As CheckBoxConstants = vbUnchecked, Optional ByVal lParam As Long) As Long

'Sample usage

SetCheckValue Check1.hWnd, , vbUnchecked    'Skip 2nd parameter
SetCheckValue Check1.hWnd, , vbChecked      'Ignore last parameter
SetCheckValue Check1.hWnd, , vbGrayed      'Choose only from the values presented
