Question

我希望从该项目的其他DLL和EXE中看到位于某个DLL中的全局变量。

我在VB文件中包含了“Option Explicit On”作为第一行。

但仍然没有人能看到我在该文件中定义的变量。我认为该项目的所有DLL都依赖于那个带有定义的DLL，但没有任何帮助。

我正在使用模块，所有变量都是公开的。

Option Explicit On

Module LPSoft_Core

#Region "Public"
Public FormHdrText As String = "PC"
Public PCBLWebHomeAddr As String = "http://"
Public PCBMSupportAddr As String = "https://emea"
Public PgmDir As String
Public GridSp As Double = 5 'mm'
Public str_GAAlpha(20) As String

Public pLoc As Point
Public Convu2mm As Single = 0.001 'convert microns to mm'
Public Convmm2u As Integer = 1000 '1 / ConvFactor_u2mm 'convert mm to microns''
Public Convmm2Inch As Double = 1 / 25.4
Public Convmm2Mil As Double = 1 / 0.0254

Public LogFile As Integer
Public strLog As String 'holds log info when logfile can't be written
#End Region

#Region "Enums"
Public Enum eCompOrient
    IPC = 0
    IEC = 1
    VPL = 2
End Enum
Public Enum eHdrGrp
    None = 0
    Alpha = 1
    OneRowOneCol = 2
    OneRowMultiCol = 3
    OneColMultiRow = 4
    TwoRowTwoCol = 5
    TwoRowMultiCol = 6
    TwoColMultiRow = 7
    MultiRowMultiCol = 8
End Enum
Public Enum PinNumber
    RowAlpha
    ColAlpha
    Numeric = 0
    Alpha = 1
End Enum

有什么想法吗？

根据this MSDN page，默认情况下，模块为Friend。为了能够从不同的项目访问它，您需要将其声明为Public，如下所示：

Public Module LPSoft_Core
    ...
End Module
