如何获得双显示器是可用或获得全宽度，包括双显示器在VB6

Question

我面临双监视器在VB6问题，请帮我找出以下任何一个。

1. 要么连接双显示器或不连接？
2. 获取屏幕的全宽（主屏+扩展显示器屏幕）

目前我使用在VB6中现有的属性。

Screen.Width & Screen.Height它给我只有主监视器的宽度和高度。

你将不得不使用Windows API来确定一个多显示器设置的虚拟屏幕尺寸：

Private Const SM_CXVIRTUALSCREEN = 78 
Private Const SM_CYVIRTUALSCREEN = 79 
Private Const SM_CMONITORS = 80 
Private Const SM_SAMEDISPLAYFORMAT = 81 

Private Declare Function GetSystemMetrics Lib "user32" (_ 
    ByVal nIndex As Long) As Long 

Public Property Get VirtualScreenWidth() As Long 
    VirtualScreenWidth = GetSystemMetrics(SM_CXVIRTUALSCREEN) 
End Property 
Public Property Get VirtualScreenHeight() As Long 
    VirtualScreenHeight = GetSystemMetrics(SM_CYVIRTUALSCREEN) 
End Property 
Public Property Get DisplayMonitorCount() As Long 
    DisplayMonitorCount = GetSystemMetrics(SM_CMONITORS) 
End Property 
Public Property Get AllMonitorsSame() As Long 
    AllMonitorsSame = GetSystemMetrics(SM_SAMEDISPLAYFORMAT) 
End Property
