.net - Generate A PDF File As System.net.mail.attachment Using Memory Stream?
Nov 25, 2011
I have a function that accepts a string and generates an email attachment based on that string. It works fine for html pages, text documents, and so forth but I can not get it to generate a PDF file.
Code:
Public Sub SendMail _
( _
ByVal strFrom As String _
[code]......
If I save the file attachment as Whatever.PDF i get the error that it was not encoded properly.I am using datadynamics active reports PDF exporter to generate the PDF
dim pdf as new datadynamics.activereports.export.pdf.pdfexport
sendmail("from@", "to@", "test", "test", pdf.tostring, "pdf.pdf")
I think the problem is I am converting the PDF to a string, and then trying to convert it back to a PDF and attach it to the email but I am not 100% sure.

I am writting a program to sendout email by reading from SQL database and get the data out for the email information: To, From, subject, body and attachment. I am importing system.net.mail.

I am trying to pass to a "SendEmail" class that I created an attachment from a stream.Here is my stream from the form:
Private Sub button_Email_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button_Email.Click
Dim myimagestream As MemoryStream = New MemoryStream()
myimage.Save(myimagestream, Drawing.Imaging.ImageFormat.Jpeg)
Dim se As New SendEmail
[Code] .....
All seems to go fine until I get the email and try to open the attachment. The file is not readable but it's not a zero byte file.

I am teaching myself vb.net and wanted to change this code to have an embedded mail.boby from a text file instead of the file attachment. Code spippet below and where I need help is mail.Body = ("tracertALL.txt")
that just puts the name of the file NOT the contents of the file. This code is a CMDWrapper that runs a batch file and I want the contents of a trace route that is pipe to a file >> tracertALL.txt .

I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.

How to convert memorystream byte array to csv file. I have GetExport method that converts rpt file to excelformatted memorystream and then returns that as a byte array. Is there a way to convert this byte array to a csv file? Due to some reasons I can only pass this byte array back to calling function.
Public Function GetExport(ByVal reportID As ReportID) As Byte()
Dim byteArray As Byte() = Nothing
Using expRptDoc As ReportDocument = New ReportDocument()
Dim rptFileName As String = Server.MapPath(ReportCommand.GetXMLReportPath(reportID))
expRptDoc.Load(rptFileName)

I am working on vb.net win form. My task is display the file names from a folder onto gridview control. when user clicks process button in my UI, all the file names present in gridview, the corresponding file has to be loaded onto memory stream buffer one after another and append the titles to the content of the file and save it in hard drive with _ed as a suffix to the file name.I am very basic programmer. I have done the following attempt and succeeded in displaying filenames onto gridview. But no idea of later part.
'Displaying files from a folder onto a gridview
Dim inqueuePath As String = "C:UsersDesktopINQUEUE"
Dim fileInfo() As String

I have a user interface app that allows you to drag/drop in files - and it turns them into HttpListener request POST's to another EXECUTABLE that I have running - let's call it BACKEND1. BACKEND1 will be running on a SERVER when this gets ready for production use. Lots and lots of users running the UI - all dragging in files - all getting POST'ed to BACKEND1 - with the file included as a memory stream in the POST. BACKEND1 responds to the UI with a "sequential" file number assigned to the file centrally on the server.
On the SERVER is also running another EXECUTABLE - let's call it BACKEND2. It's job is to work with the DRAG'd in files. Both BACKEND1 and BACKEND2 sit on the same SERVER. At the moment I am writing the memory stream to DISK in BACKEND1 - and POSTing the FILENAME to BACKEND2 for it to work on. Would it be better to not write the file in BACKEND1 but instead include it in the POST to BACKEND2 - where it can be written to DISK? Is having LARGE HTTP REQUEST's a burden when sent between two EXECUTABLES on the same machine?
My primary goal is to have a really available BACKEND1 talking the the UI instances running out in the world. I'm concerned that doing the file i/o in BACKEND1 is "expensive" - and I don't care about the performance of BACKEND2 as much. just looking for opinions. I guess ultimately I'll have to bench mark this myself in a production environment to get a real answer.

I am using iTextSharp with VB.Net to stamp images onto PDF documents. (Since this is not language specific I tagged for C#, too.)I have two applications using the process.The first uses the bytes from the memorystream to display the PDF documents online. This piece is working. The second uses the same function but instead saves the PDF to a file. This piece generates an invalid PDF.
I have seen some similar questions, but they are all creating a document initially and have a document object in the code. Their memory streams are corrupt from the outset. My code does not have a document object and my original memory stream opens fine.
Here is the place where I get the error: (I have to put the buffer from m into a new memory stream because the stamper in the fillPDF function defaults to closing the stream unless marked otherwise.)
Dim m As MemoryStream = PDFHelper.fillPDF(filename, Nothing, markers, "")
Dim m2 As New MemoryStream(m.GetBuffer, 0, m.GetBuffer.Length)
Dim f As FileStream = New FileStream("C: emp.pdf", FileMode.Create)

What I would like to do is allow the user to click a button which will open their default email program (e.g. outlook, windows live mail, etc) and create a new email with an attachment (from io.stream) ready for them.

Once again I've ran into a (at least for me) weird problem, which I can't figure out.I have a form which allows users to send an email with an attachment and also stores the email in an accessdatabase. When sending an email without an attachment, there is no problem and all is saved to the database.
But when sending an email with an attachment, it produces an error that the database is not found, and therefore nothing is saved to the database.

this is the problem.Write a program to generate a business travel expense attachment for an income-tax return. The program should request as input the name of the organization visited, the date and location of the visit, and the expenses for meals and entertainment, airplane fare, lodging, and taxi fares. (Only 50% of the expenses for meals and entertainment are deductible.) The output is displayed in a list box that becomes visible when the button is clicked. Sub procedures should be used for the input and output.sample input and output can be shown here: Book reviews: An Introduction to Programming Using Visual Basic 2005. Chapter 4 Programming Projects
my error is "too many argument in Public Sub InputValues(.......)"
my code is this: i used indexof because for example the user inputted a date with a year then the output will ignore the year. only the month and specific date will appear.

I've implemented with Visual Basic 10 an application for Net Framework 4 with functionality to send files via e-mail using System.Net.Mail. It works well except when it comes to sending an XML file whose name contains accents. In the latter case the UTF-8 name is not correct, so Widows Mail Life presents him with name consisting of a set of meaningless characters. Furthermore, the content has lost the format of lines and spaces, presented part of MIME type information in the header, so that it is unreadable XML readers. However, with a name without accents is sent successfully.[code]....

I'm using the ShockwaveFlash ActiveX control in a VB.NET Windows Forms application and i'm wondering.Is it possible to load an SWF file into the ShockwaveFlash ActiveX object from a memory stream rather then from a file name?
I've noticed that the ActiveX object has such properties as "InlineData" and "MovieData", possibly these could be used.
I've also noticed someone has used Windows Messaging to send a pointer to a stream to the ActiveX control, has anyone seen this done?
