Attachments Using REST WebService
May 26, 2011
I am currently developing an application using VB.NET in which I am using the REST WebServices. I have been able to do the basics with REST, however, I have not been able to add an attachment (more specifically upload a file, using REST which gets attached). I have done extensive research online, but so far I have not been able to find any working examples in VB.NET. To actually upload the data I use System.Net.WebClient. The following VB.NET code does the important work:[code]As you can see, the postString is converted to bytes and then uploaded to the server. However, I do not know where or how I should be posting the raw attachment itself. The documentation for the service we are specifically using states to use a variable "attachment_ 1," which I added to the postString variable, but I am not sure what the next step should be. Should the file be converted into bytes and appended to the postBytes variable?

I need to use a web service that was provided to me and that uses SOAP with attachments as a means of communication. It also uses WS-Security 1.0 as a form of authencation (user and pass in plain text).I will be working on VB.NET and my experience with web services is very slim, and goes as far as creating a WCF web service, adding the service reference in another project thus creating a proxy class and using the methods.I have searched the internet and found that there is no native support for SwA in VB.NET, is this correct?

How do I post this HTTP REST request using HttpWebRequest and System.Xml.XmlDocument in vb.net
<tns:request command="hello" xmlns:tns="http://www.xxyyzz.com/xx/yy/zz" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
The server responds with
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><response xmlns="http://www.xxyyzz.com/xx/yy/zz"><operation location="/mm/10d9c79e-5876-4fd0-9093-ff7bdee5ebd4/uploadInfo" command="uploadInfo"/></response>

I'd like a free library for .NET to get attachments from an account (such as gMail, or others) via imap4 (not necessarely), and save them in a folder. Ideally it would allow me to get a list of them, and download only some given ones (filtering by extension, name, and/or size) and be free. I've already done this with a trial version of EAGetMail, but for the purpose of what i'm trying to attempt buying the unlimited version of this library isn't quite suitable (i didn't know that this functionality itself was one among the ones with limited time).
I'm using the following code:
Dim cl As New Pop3Client()
cl.UserName = "marcelo.f.ramires@gmail.com"
cl.Password = "mypassword"
cl.ServerName = "pop.gmail.com"
cl.AuthenticateMode = Pop3AuthenticateMode.Pop
cl.Ssl = False
cl.Authenticate() //takes a while, but passes even if there's a wrong password
Dim mg As Pop3Message = cl.GetMessage(1) //gives me an exception: Message = "Pop3 connection is closed"
Setting the port to 995 gives me a "Response TimeOut" exception

I have a supplier that sends me certifications for material that I purchase. We have come up with a new system where the certs will be sent to me via e-mail as attachments to a specific account I would like to automate the process so that everyday a program runs that looks for new e-mails and when it finds one, it opens it and saves the attachments to a file share. found a nice piece of code that should do what I am looking to do but it isn't working. It executes but where it should be going through the e-mails it isn't finding any. I put in a bunch of debug code and found that my program is getting a "440 Login Timeout" reply from the server when it requests a list of the e-mails in the account.

First off, I would like to say that I'm sorry for having to ask a programming site where to find a download for the outlook reference (msoutl9.olb) that is supposed to be in my C: drive. but I just joined and this community is pretty helpful so I thought I would ask.
My problem come about when I try and use Dim olApp As New Outlook.Application Dim olMail As Outlook.MailItem
It tells me that I need to add references and I went to Tools and the References option was greyed out so I could not click it. I have no idea why this would happen so I googled many topics relating to references in access and vba. After about 2 hours of researching I had gotten nowhere. But I did learn that I am missing this file that is supposed to come with Microsoft Access (msoutl9.olb).
I have searched around and found nothing relating to downloading this file. Do I have to redownload Access or can anyone give me a link to download this file? Also, if there is another way to get around using the Outlook.Application portion of my code I would love to learn how.

When I start typing a variable (or whatever), VB pops up a little box with all possible variables starting with the letters I already typed. It's really smart!
However this option has somehow been disabled. How do I enable it again?

I have located some sample source code in visual basic to call a REST API. However, I need to modify the code by adding two request headers.
' Create the web request
request = DirectCast(WebRequest.Create(sURI), HttpWebRequest)
'Update request headers with request pairs Header1/"header1 value" and header2/"header2 value"
??? HttpWebRequest.headers.Add ????

For this program im using http method post to recieve messages from the server, when its waiting for a new message to be sent it locks the program up. No biggie, ill just thread the sub... Bad idea... I also have functions "send", "Connect", "disconnect". All on threads... i looked at task manager it started getting up to 100+ threads. I dont know much about threads but that just seems way to much. they will die off and the count will return to 20 but id like to find a different way of keeping the program from locking up but not having 100+ threads.. Little off topic: i used a user control. The only problem now is on the tab, its not anchored with the rest of the form... how do i accomplish this?

My Outlook addin checks (when user click "send") if a large attachment is attached. If so it should remove it and cancel the sending and give focus back to the user.Here's a sample of my Outlook addin code...
Private Sub ThisApplication_ItemSend(ByVal Item As Object, ByRef Cancel As Boolean) Handles Application.ItemSend
Dim mail As Outlook.MailItem = CType(Me.Application.ActiveInspector.CurrentItem, Outlook.MailItem)
For i As Integer = mail.Attachments.Count To 1 Step -1
[code]....
The active mail item still shows all the attachements.How do I get Outlook to remove all the attachments (before user sends the mail) and cancel the sending?

I'm writing a program to work with access and one of the columns is an attachment data type. I was trying to use a INSERT INTO statement however it errors and tells me that INSERT can't be used for a multivalue field. Makes sense since an attachment type will allow for multiple files however I'm stumped how to make this work. Anyone run into this and if so what's the resolve? Is there a way to make .net make this happen programmatically? The only other thing I can think to do is save the file path or copy the file to another specified location and then save that file's path. To me that's not a good workaround and I'd like to use Access for what it can do.

I am trying to extract a saved image from a database and then attach it as a image to an email. I can get the image saved into a Bitmap object but attaching it is not going so well. Here is what I got:
Dim rawData() As ByteDim byteArray() As ByteDim ad As New System.IO.MemoryStreamDim bm As Bitmap
byteArray = imageData.Item("img") ' imageData is my dataread for the tablerawData = New Byte(byteArray.Length) {}
[Code].....
I have tried several variations so the code might be convoluted, but basically I am putting the image into a byteArray and Bitmap (which was something added later on) but also trying use the Mail library to attach the image but also have the image referenced within the html body of the email in which it will be embedded. The attachment part seems to work - some what - but the image itself is not getting attached.

In order for my program to share information between users, the best method I could come up with is using e-mails.I have a way of sending e-mails with the appropriate attachments, but would love a way to automatically retrieve these e-mail attachments directly from the program, without the user having to go to their e-mail account, find the correct project e-mail, download the attachment and then put it in the correct folder.I had hoped that VB.Net would have a built in procedure for doing this, but it seems there's not really anything there.

I am trying to retrieve an attachment from a lotus notes email using the EmbeddedObjects array off of a NotesDocument object. In my test, I've set up an email with an attachment and am trying to process it. The HasEmbedded property of the NotesDocument object is returning true however the EmbeddedObjects array of the NotesDocument object is always nothing (null). Why is the EmbeddedObjects array always nothing?
