Do not generate file in disk, instead send mail with data in memory - asp-classic

Question

I have a piece of code that works and do:
Reads a Database , reads a template (template.htm), put data in a new file based in the template (evento.htm), read that file and send an email with the content of the file generated. Code below (I cut the database part):
<%
NomeDoTemplate= "template.htm"
CaminhoDoTemplate= Server.MapPath(NomeDoTemplate)
CaminhoDoTemplateAjustado= Mid(CaminhoDoTemplate,1,InStrRev(CaminhoDoTemplate,"\"))
NomeDoArquivo= "evento.htm"
CaminhoDoArquivo= Server.MapPath(NomeDoArquivo)
Set ManipulacaoDeArquivo= Server.CreateObject("Scripting.FileSystemObject")
Set ObjetoArquivo= ManipulacaoDeArquivo.OpenTextFile(CaminhoDoTemplate, 1)
DadosDoObjetoArquivo= ObjetoArquivo.ReadAll
ObjetoArquivo.Close
DadosDoObjetoArquivo= Replace(DadosDoObjetoArquivo, "[Cliente]", Um)
Set ObjetoArquivo= ManipulacaoDeArquivo.CreateTextFile(CaminhoDoTemplateAjustado & NomeDoArquivo)
ObjetoArquivo.Write(DadosDoObjetoArquivo)
Set ObjetoArquivo= ManipulacaoDeArquivo.OpenTextFile(CaminhoDoTemplateAjustado & NomeDoArquivo, 1)
DadosDoObjetoArquivo= ObjetoArquivo.ReadAll
Dim objCDOSYSMail
Dim objCDOSYSCon
Set objCDOSYSMail = Server.CreateObject("CDO.Message")
Set objCDOSYSCon = Server.CreateObject ("CDO.Configuration")
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.server.com"
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendusername") = "user_id"
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 30
objCDOSYSCon.Fields.update
Set objCDOSYSMail.Configuration = objCDOSYSCon
objCDOSYSMail.From = "ABC <abc#server.com>"
objCDOSYSMail.To = "sender#gmail.com"
objCDOSYSMail.Subject = "Contato"
objCDOSYSMail.HTMLBody= DadosDoObjetoArquivo
objCDOSYSMail.Send
Set objCDOSYSMail = Nothing
Set objCDOSYSCon = Nothing
%>
I would like to make this simple, skiping the step of generating the file in the disk. I would like to:
Read a Database, reads a template, put data in memory, send the mail with that data in memory.
Thanks

If I see it correctly, all you have to do is skip the part where you save the file and re-read it... I have refactored your code, gave the variables some english names so I could see what's going on, and commented out the lines you don't need:
<%
Dim TemplateName : TemplateName = "template.htm"
Dim TemplateFullPath : TemplateFullPath = Server.MapPath(TemplateName)
Dim TemplatePath : TemplatePath = Mid(TemplateFullPath,1,InStrRev(TemplateFullPath,"\"))
Dim ArchiveName : ArchiveName = "evento.htm"
Dim ArchiveFullPath : ArchiveFullPath = Server.MapPath(ArchiveName)
Dim FSO, TemplateFile, TemplateText
Set FSO = Server.CreateObject("Scripting.FileSystemObject")
Set TemplateFile = FSO.OpenTextFile(TemplateFullPath, 1)
TemplateText = TemplateFile.ReadAll()
TemplateText = Replace(TemplateText, "[Cliente]", Um)
TemplateFile.Close()
' Really simple - to do this in-memory, simply don't save and re-read the file....
' Set TemplateFile = FSO.CreateTextFile(TemplatePath & ArchiveName)
' TemplateFile.Write(TemplateText)
' Set TemplateFile = FSO.OpenTextFile(TemplatePath & ArchiveName, 1)
' TemplateText = TemplateFile.ReadAll
Set TemplateFile = Nothing
Set FSO = Nothing
Dim objCDOSYSMail, objCDOSYSCon
Set objCDOSYSMail = Server.CreateObject("CDO.Message")
Set objCDOSYSCon = Server.CreateObject ("CDO.Configuration")
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.server.com"
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendusername") = "user_id"
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 30
objCDOSYSCon.Fields.update
Set objCDOSYSMail.Configuration = objCDOSYSCon
objCDOSYSMail.From = "ABC <abc#server.com>"
objCDOSYSMail.To = "sender#gmail.com"
objCDOSYSMail.Subject = "Contato"
objCDOSYSMail.HTMLBody= TemplateText
objCDOSYSMail.Send
Set objCDOSYSMail.Configuration = Nothing
Set objCDOSYSMail = Nothing
Set objCDOSYSCon = Nothing
%>
Hope this helps,

Answer 2

you could use several techniques:
write your own stringbuilder class
use the .net system.io.stringwriter class (yes you can use this from classic asp)
use the adodb.stream object
example stringwriter:
set sw = server.createObject("system.io.stringwriter")
sw.write_12( DadosDoObjetoArquivo )
objCDOSYSMail.HTMLBody = sw.getStringBuilder().toString()
example (adodb.stream):
set stream = server.createobject("ADODB.Stream")
with stream
.Open
.WriteText DadosDoObjetoArquivo
end with
objCDOSYSMail.HTMLBody = stream.ReadText
stream.Close
