在我的数据库中,我可以使用以下命令按钮导入文件: DoCmd.TransferText acImportDelim,“Import_ Import Specification中的原始数据”,“导入的原始数据”,D:\ Users \ Denise_Griffith \ Documents \ Griffith \ PRIME RECON FILES \ jdaqawmslesfilesemailDLX_SHPREC_2017-04-26_03-33-47.csv,True, “”
但是我想让用户选择要导入的文件,因为文件名每天都会根据创建的日期和时间而不同。我找到了这个站点(http://access.mvps.org/access/api/api0001.htm),并且能够弹出对话框以允许用户导航并选择文件,但我不知道如何合并它,因此所选文件是使用我创建的规范,并进入相应的表。
请帮忙!

您需要设置对 Microsoft Office对象库的引用。
Public Sub ImportDocument()
On Error GoTo ErrProc
Dim fd As FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
With fd
.InitialFileName = "Some folder"
.Title = "Some Title"
With .Filters
.Clear
.Add "CSV documents", "*.csv", 1
End With
.ButtonName = " Import Selected "
.AllowMultiSelect = False
If .Show = 0 Then GoTo Leave
End With
Dim selectedItem As Variant
For Each selectedItem In fd.SelectedItems
DoCmd.TransferText acImportDelim, "Raw Data from Import_ Import Specification", "Raw Data from Import", selectedItem, True, ""
Next
Leave:
Set fd = Nothing
On Error GoTo 0
Exit Sub
ErrProc:
MsgBox Err.Description, vbCritical
Resume Leave
End Sub
在用户评论后更新:
您必须将 Sub 更改为功能并检查返回值。
最简单的方法是返回Boolean
,其中FALSE
表示已中止,TRUE
表示成功。但是,通过这样做,您可以排除错误方案,因为Aborted和Error都将返回FALSE
。
因此,您可以返回Long
值,例如0,1,2分别表示中止,成功和错误。为了避免"魔术数字"但是,我会创建并返回 Enum 类型,如下所示:
Public Enum TaskImportEnum
Aborted = 0 'default
Success
Failure
End Enum
Public Function ImportDocument() As TaskImportEnum
On Error GoTo ErrProc
Dim fd As FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
With fd
.InitialFileName = "Some folder"
.Title = "Dialog Title"
With .Filters
.Clear
.Add "CSV documents", "*.csv", 1
End With
.ButtonName = " Import Selected "
.AllowMultiSelect = False 'Change this to TRUE to enable multi-select
'If aborted, the Function will return the default value of Aborted
If .Show = 0 Then GoTo Leave
End With
Dim selectedItem As Variant
For Each selectedItem In fd.SelectedItems
DoCmd.TransferText acImportDelim, "Raw Data from Import_ Import Specification", "Raw Data from Import", selectedItem, True, ""
Next selectedItem
'Return Success
ImportDocument = TaskImportEnum.Success
Leave:
Set fd = Nothing
On Error GoTo 0
Exit Function
ErrProc:
MsgBox Err.Description, vbCritical
ImportDocument = TaskImportEnum.Failure 'Return Failure if error
Resume Leave
End Function
最后,您可以像这样调用函数:
Sub Import()
Dim status_ As TaskImportEnum
status_ = ImportDocument
Select Case status_
Case TaskImportEnum.Success:
MsgBox "Success!"
Case TaskImportEnum.Failure:
MsgBox "Failure..."
Case Else:
MsgBox "Aborted..."
End Select
End Sub
