英文:
MS Access button to open a PDF on a server
问题
我们正在尝试创建一个交付证明数据库,并希望在表单上添加一个按钮,该按钮可以打开服务器上扫描的PDF文件。
在表格中,我们已经创建了一个计算字段的表达式 [Location] & [Invoice No] & [PDF],它显示文件的位置(Z:\Carriers\POD\123.pdf)。
是否有一种方法可以在表单中创建一个按钮,以查看 [文件位置] 字段并打开PDF文件?
英文:
We are trying to create a proof of delivery database and would like a button on a form that would open a scanned pdf on our server.
In the table we have created a expression in a calculated field [Location] & [Invoice No] & [PDF] which displays the location of the file (Z:\Carriers\POD\123.pdf)
Is there a way to create a button in a form that will look at [File Location] field and open the pdf

感谢您的建议,无法使它们起作用。
找到了关于FollowHyperlink的信息并使用了这个代码:
Application.FollowHyperlink "Z:\Carriers\POD" & Me.[Invoice] & ".pdf"
正好满足了我们的需求。
再次感谢大家的时间。
英文:
Thanks for your suggestions, could not get them to work.
Found info about FollowHyperlink and used this
Application.FollowHyperlink "Z:\Carriers\POD" & Me.[Invoice] & ".pdf"
Does exactly what we need
Thanks everyone again for your time

你可以使用这个函数,它将打开任何 Windows 可以显示的文件:
Option Compare Database
Option Explicit
' 用于 OpenDocumentFile 的 API 声明。
' 文档:

Private Declare PtrSafe Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _
ByVal hWnd As Long, _
ByVal lpOperation As String, _
ByVal lpFile As String, _
ByVal lpParameters As String, _
ByVal lpDirectory As String, _
ByVal nShowCmd As Long) _
As Long
Private Declare PtrSafe Function GetDesktopWindow Lib "USER32" () _

' ShowWindow 常量的枚举(选择)。

swShowMinimized = 2
swShowMaximized = 3
End Enum
' 使用默认的查看器应用程序打开文档文件。

' 如果成功返回 True,否则返回 False。

Public Function OpenDocumentFile( _
ByVal File As String, _
Optional ByVal ShowCommand As SwShowCommand = swShowNormal) _
As Boolean
Const OperationOpen As String = "open"
Const MinimumSuccess As Long = 32
' 打开文档不应该有一个值。
Const Parameters As String = ""
Dim Handle As Long
Dim Directory As String
Dim Instance As Long
Dim Success As Boolean
Handle = GetDesktopWindow
Directory = Environ("Temp")
Instance = ShellExecute(Handle, OperationOpen, File, Parameters, Directory, ShowCommand)
' 如果函数成功,它将返回大于 MinimumSuccess 的值。
Success = (Instance > MinimumSuccess)
OpenDocumentFile = Success
End Function
注意:这是 Visual Basic for Applications (VBA) 代码,用于在 Windows 上打开文件的功能。
英文:
You can use this function which will open any file, that Windows can display:
Option Compare Database
