B4J Code Snippet Send Mails with attachements over local Outlook installation via VBS script

I use this script to send over 1500 Mails with invoices. Outlook starts in the background or foreground if it is started. You need an installed Outlook application.


B4X:
Const olByValue = 1
Const olMailItem = 0
    
Dim oOApp
Dim oOMail

Set oOApp = CreateObject("Outlook.Application")
Set oOMail = oOApp.CreateItem(olMailItem)

With oOMail
    .To = "customer@someserver.com"
    .SentOnBehalfOfName = "myemailaddress@mycompany.com"
    .Subject = "Subject"
    .Body = "The mailbody"
    '.Attachments.Add "C:\somefile.txt", olByValue, 1
    '.Send -> send direct, .Save = Draft
    .DeferredDeliveryTime = Date & " 22:00:00" 'delay if needed
    .send
End With

With the help of the TextWriter object (to create Windows files with the correct codepage) I create the script at runtime. The scriptfile contains a "header" with the definitions to get access to Outlook, and the send parameters for each mail with the file path to the attachment. At the end I start it via jShell.

Please use Google to check more options (search for vbs & Outlook & send mails). Quite easy.

B4X:
Dim Writer As TextWriter
            Writer.Initialize2(File.OpenOutput(File.DirApp & "/SENDMAILVBS","sendmails.vbs", False),"cp1252")
            Dim vbsscript As String
            
            
            vbsscript=$"outFile="${File.DirApp}/SENDMAILVBS/${BatchName}.log""$ & CRLF
            Writer.WriteLine(vbsscript)
            vbsscript=$"Set FSO = CreateObject("Scripting.FileSystemObject")"$
            Writer.WriteLine(vbsscript)
            vbsscript="Set objFile = FSO.CreateTextFile(outFile,True)" & CRLF &CRLF
            Writer.WriteLine(vbsscript)
            
            vbsscript ="Const olByValue = 1" & CRLF & "Const olMailItem = 0" & CRLF & "Dim oOApp" & CRLF & "Dim oOMail" & CRLF & $"Set oOApp = CreateObject("Outlook.Application")"$ & CRLF
            Writer.WriteLine(vbsscript)

for each mail
