excel - 为什么传递参数会产生错误argumenttype ByRef？

问题描述

我在 VBA 中为邮件合并编写了延迟代码。
我以前从未使用过 VBA。

邮件合并工作正常。现在我想输入一个随机数而不是Call Pause(15).

Sub Letter_EN()
' Merges one record at a time to email with a pre-defined delay between messages.
' Sourced from: https://www.msofficeforums.com/mail-merge/38282-email-merge-delay.html

If MsgBox("Wirklich an Company_EN senden?", vbYesNo, "Senden") <> vbYes Then Exit Sub
Application.ScreenUpdating = False
Dim i As Long
With ActiveDocument
  For i = 1 To .MailMerge.DataSource.RecordCount
    With .MailMerge
      .Destination = wdSendToEmail
      .MailSubject = "Company wishes you a merry Christmas!"
      .MailFormat = wdMailFormatHTML
      .MailAddressFieldName = "EMAIL"
      .SuppressBlankLines = True

      With .DataSource
        .FirstRecord = i
        .LastRecord = i
        .ActiveRecord = i
      End With
      .Execute Pause:=False
    End With
    Call Pause(15)
  Next i
End With
Application.ScreenUpdating = True
End Sub

Public Function Pause(Delay As Long)
Dim Start As Long
Start = Timer
If Start + Delay > 86399 Then
  Start = 0: Delay = (Start + Delay) Mod 86400
  Do While Timer > 1
    DoEvents ' Yield to other processes.
  Loop
End If
Do While Timer < Start + Delay
  DoEvents ' Yield to other processes.
Loop
End Function

我知道 300 - 480 秒之间的随机数的公式是：

Dim MyValue As Integer
zahl= Int((480 - 300 + 1) * Rnd + 300)

但是，如果我插入而不是 15 - MyValue 错误参数类型 ByRef 来

解决方案

假设您希望将下面的 15 替换为 300 - 480 范围内的值：

Call Pause(15)

这应该变成：

Dim PauseDelay As Integer
PauseDelay = Int((480 - 300 + 1) * Rnd + 300) ' Stores the random interval between 300-480
Call Pause(PauseDelay) ' Calls Pause with the random interval

有什么我忽略的吗？这段代码看起来很简单，你似乎已经有了答案
