access vba DoCmd.OpenForm“操作已取消”

Question

Private Sub OccurrenceName_AfterUpdate()
If OccurrenceName.Value = "Other" Then
    Dim strTechID As String
    Dim strOccurrenceCt As String
    Dim strOccurrenceDate As String

    strTechID = Me.Parent.tbxTechID.Value
    strOccurrenceCt = Forms![frmEmployeeOccurrenceInput]![tbxOccurrence].Value
    strOccurrenceDate = Me.OccurrenceDate.Value

    Dim strOpenArgs As String
    strOpenArgs = strTechID & "|" & strOccurrenceCt & "|" & strOccurrenceDate

    DoCmd.OpenForm "frmOtherOccurrence", , , , , , strOpenArgs
Else
    Me.OccurrenceAmt = Me.OccurrenceName.Column(1)
    Me.Type = Me.OccurrenceName.Column(2)
End If
End Sub

每次运行时，我都会得到一个错误代码为2501的“打开表单操作被取消”。它捕捉到的线路是DoCmd.OpenForm调用。调试不会提供额外的信息。

下面是将OpenArgs传递到的位置：

Private Sub Form_Load()

Dim aryOA As Variant

aryOA = Split(Me.OpenArgs, "|")

Me.lblTechID.Caption = aryOA(0)
Me.lblOccurrenceCt.Caption = aryOA(1)
Me.lblOccurrenceDate.Caption = aryOA(2)

End Sub

Answer 1

我不知道这是不是你的问题，但是你不能将OpenArgs传递给一个打开的表单，我的意思是它甚至不能处于编辑模式，应该完全关闭。

否则，表单将打开(将其状态从编辑模式更改为normal)，但不会传递任何OpenArgs，因此OpenArgs将为null并抛出异常。
