问题描述
我想在不打开 Lotus Notes UI 的情况下发送带有 vbscript 的邮件。我设法编写了一个脚本，允许发送带有附件的电子邮件，并且一切正常。但是，当我运行宏时会启动应用程序，我希望它安静地工作（不启动应用程序）。
这是我的代码：
findAllSeq2n <- function(n){
f <- function(d,out,start,end){
if (abs(d) > (end - start + 1) / 2) return(NULL)
if (start > end) {
if (d == 0) {
#cat(out,"\n")
return(out)
}
}
out[start] <- 0L
out[end] <- 1L
s01 <- f(d + 1L,start + 1L,end - 1L)
out[start] <- 1L
out[end] <- 1L
s11 <- f(d,end - 1L)
out[start] <- 0L
out[end] <- 0L
s00 <- f(d,end - 1L)
out[start] <- 1L
out[end] <- 0L
s10 <- f(d - 1L,end - 1L)
do.call(cbind,list(s01,s11,s00,s10))
}
out <- integer(2*n)
f(0,1,2*n)
}
findAllSeq2n(2)
# [,1] [,2] [,3] [,4] [,5] [,6]
#[1,] 0 1 1 0 0 1
#[2,] 1 1 0 1 0 0
#[3,] 0 1 0 1 0 1
#[4,] 1 1 1 0 0 0
findAllSeq2n(3)
findAllSeq2n(4)
问题是每次运行宏时都会启动Lotus notes UI，因为这一行：
Dim noSession As Object
Dim noDatabase As Object
Dim nodocument As Object
Dim paths() As String
'Instantiate the Lotus Notes COM's Objects.
Set MailSession = CreateObject("Notes.NotesSession")
Set MailDatabase = MailSession.GetDatabase("","")
'If Lotus Notes is not open then open the mail-part of it.
If MailDatabase.IsOpen = False Then MailDatabase.OPENMAIL
'Create the list of recipients.
vaRecipients = VBA.Array(EmailTo)
vaCCRecipients = VBA.Array(EmailCC)
vaBCCRecipients = VBA.Array(EmailBCC)
Set MailDoc = MailDatabase.CreateDocument
MailDoc.Form = "Memo"
MailDoc.sendTo = vaRecipients
MailDoc.copyTo = vaCCRecipients
MailDoc.BlindcopyTo = vaBCCRecipients
MailDoc.Subject = Subject
MailDoc.Body = Body
MailDoc.SAVEMESSAGEONSEND = True
MailDoc.ReplyTo = Sender
MailDoc.SMTPOriginator = Sender
MailDoc.Sender = Sender
MailDoc.principal = Sender
MailDoc.inetprincipal = Sender
MailDoc.from = Sender
MailDoc.inetfrom = Sender
MailDoc.displayfrom = Sender
paths = Split(AttachmentPaths,";")
Dim richTextItem As Object
Dim AttachmentPath As String
For i = LBound(paths()) To UBound(paths())
AttachmentPath = paths(i)
Set richTextItem = MailDoc.CreateRichTextItem("Attachment" & i)
Call richTextItem.Embedobject(1454,"",AttachmentPath)
Next i
MailDoc.Send 0,vaRecipients
'Release objects from memory.
Set nodocument = nothing
Set noDatabase = nothing
Set noSession = nothing
MsgBox "The e-mail has successfully been created and distributed",vbinformation
解决方法
您认为 OPENMAIL 是客户端打开的原因是错误的。
真正的问题是您对基于 OLE 的对象类“Notes.NotesSession”的使用。 如果您真的想在不打开笔记的情况下离开 - 客户端，您需要使用基于 COM 的对象类“Lotus.NotesSession”或“Domino.NotesSession”。
问题是：使用 Lotus.NotesSession 时，您需要自己用密码初始化会话（密码必须在代码中），否则黑色 DOS-Prompt 将询问您的 Notes-密码。使用“Notes.NotesSession”时，客户端本身用于身份验证。这就是它在运行代码时打开的原因。如果它已经打开，则不会发生任何事情。
你可以查看this old post了解更多细节，它的原理仍然是正确的。
代码与其他类几乎相同，您还需要一个正确安装的 Notes 客户端。你只需要初始化会话而不是仅仅使用它：
Set MailSession = CreateObject("Lotus.NotesSession")
MailSession.Initialize( "yourpassword" )
如果您不输入密码，系统会提示您输入。
