Question

我正在尝试编写一个应用程序，用于从PC向手机发送和接收服务电话。

我正在使用一个名为mobile data studio的程序来完成大部分工作。

基本上，程序会为客户生成一个网页作为其报告，并通过我工作的系统邮寄给客户

问题是系统在尝试将其作为附件发送之前不会等到文件生成，我收到错误：

CDO.Message1

系统找不到指定的文件。

位置：58.0

这是代码：

objmessage.Addattachment sFile

如果我在错误上单击“确定”，则会创建该文件，如果我再次运行该脚本，则会处理邮件和附件，并在传真设置为“是”的情况下打开文件。

这是所有代码：

' Process incoming sessions from Pocket PCs

Function OnIncomingSession (theSession)             
' Check if the user indicated a confirmation was desired
If theSession("SendEmail") = "Yes" Then    
 sendobjMessage theSession     
    ElseIf theSession("SendFax") = "Yes" Then      
 sendobjfax theSession               
 End If

   ' Set the return value to true to indicate that normal
' processing should continue
OnIncomingSession = True 

End Function

Sub sendobjMessage (theSession)
' Get the email address from the session
 sEmail = theSession ( "EmailAddress" )

 'Get the file name from the session
 sFile = "C:\htm\"& theSession("ORN")&"."&"htm"   

Const cdoSendUsingPickup = 1 'Send message using the local SMTP service pickup directory. 
Const cdoSendUsingPort = 2 'Send the message using the network (SMTP over the network). 

Const cdoAnonymous = 0 'Do not authenticate
Const cdoBasic = 1 'basic (clear-text) authentication
Const cdoNTLM = 2 'NTLM

Set objMessage = CreateObject("CDO.Message") 
objMessage.Subject = "Our Company  - Service Report" & " " & theSession("rdate")  
objMessage.From = """Service Department"" <user@mydomain>" 
objMessage.To = sEmail
objMessage.TextBody = "Hi " & theSession("sname") & ","
objmessage.Addattachment sFile

Set objfax = CreateObject("WScript.Shell")
objfax.Run sFile

Option Explicit
Dim retval, fso, file
Set fso = CreateObject ("scripting.filesystemobject")

file = "c:\temp\myfile.txt"
retval = waitTilExists (file, true)
MsgBox "return value: " & retval


Function waitTilExists (ByVal file, withRepeat)
    ' Sleeps until the file exists
    ' The polling interval will increase gradually, but never rises above MAX_WAITTIME
    ' Times out after TIMEOUT msec. Will return false if caused by timeout.
    Dim waittime, totalwaittime, rep, doAgain
    Const INIT_WAITTIME = 20
    Const MAX_WAITTIME = 1000
    Const TIMEOUT = 5000
    Const SLOPE = 1.1
    doAgain  = true
    Do While doAgain
        waittime = INIT_WAITTIME
        totalwaittime = 0
        Do While totalwaittime < TIMEOUT
            waittime = Int (waittime * SLOPE)
            If waittime>MAX_WAITTIME Then waittime=MAX_WAITTIME
            totalwaittime = totalwaittime + waittime
            WScript.sleep waittime

我可能会有一些有用的工具我得到你需要的印象：

在一段时间内造成延迟或暂停的例程
检查文件是否存在的例程。

以下是创建延迟或暂停的例程：

Sub subSleep(strSeconds) ' subSleep(2)
    Dim objShell
    Dim strCmd
    set objShell = CreateObject("wscript.Shell")
    'objShell.Run cmdline,1,False

    strCmd = "%COMSPEC% /c ping -n " & strSeconds & " 127.0.0.1>nul"     
    objShell.Run strCmd,0,1 
End Sub

这是检查文件存在的例程：

Function fnFileExists_Bln(strFULLNamee)
    Dim strFULLName
    strFULLName = strFULLNamee

    Dim objFSO
    Set objFSO = CreateObject("scripting.filesystemobject")

    fnFileExists_Bln = objFSO.FileExists(strFULLName)
End Function ' Function fnFileExists_Bln(strFULLNamee)

我希望这会有所帮助。

让vbscript等到文件存在
