Value to pass to WIN32 API Function MonitorFromWindow as DWORD

Sarah Thomas |

The function calling the API in vba:

Private Declare PtrSafe Function MonitorFromWindow Lib "user32" (ByVal HWND As Long, ByVal DWORD As Long) As HMONITOR

I have tried to pass 0 as dword, 

Debug.Print MonitorFromWindow(Application.HWND, 0)

hoping to get MONITOR_DEFAULTTONEAREST but the function returns nothing. What are the values of the below constants?

For instance other API's list the value underneath the constant:

These constants are defined in the SDK include file "WinUser.h" as

#define MONITOR_DEFAULTTONULL 0x00000000 #define MONITOR_DEFAULTTOPRIMARY 0x00000001 #define MONITOR_DEFAULTTONEAREST 0x00000002
