Did you ever get this to work?

I was able to get it to work with the following code:

public void CTRL35_5_Clicked(object sender, ClickedEventArgs e)

{

// Write your code here.

XPathNavigator mainDS = MainDataSource.CreateNavigator();

string base64EncodedString = mainDS.SelectSingleNode(

"my:myFields/my:Attachment", NamespaceManager).Value;

if (!String.IsNullOrEmpty(base64EncodedString))

{

DecoderInfoPathA.

InfoPathAttachmentDecoder decoder =

new DecoderInfoPathA.InfoPathAttachmentDecoder(base64EncodedString);

System.IO.

File.WriteAllBytes(

@\\Your\Path\Here + decoder.Filename, decoder.DecodedAttachment);

}

The only problem is that it will only work when the InfoPath form is in full trust...

I was hoping you may know a way to code in C# to have it have full trust when using InfoPath in client version only.

Hi there,

I've been trying to achieve a similiar thing myself, and as far as I understand qDabra is the only way to do it (as you can't upload files directly through infopath or sharepoint as it is). I believe there is a way to do this using K2's SmartObjects, but i haven't tried this myself.

Maybe a sneaky way could be to establish a web service you can call, submitting the base64 data and the web service itself saves it as a file?

Let me know if you find a solution, i'd be very interested to see one :)

How to submit an attachment

I've read through all of the articles on this forum about how to save a file attachment from an infopath form, but i havent yet been able to really get it to work. My form already has a whole bunch of C# code in it, so the qDabra rules won't work. I've tried to use the bizsupportonline.net examples:

http://www.bizsupportonline.net/blog/2009/01/submit-infopath-form-sharepoint-list-attachment/
http://www.bizsupportonline.net/blog/2009/02/submit-file-attached-infopath-form-as-attachment-sharepoint-list-item/

but can't get either one to work as i dont have access to the sharepoint server to get the microsoft.sharepoint.dll file to complile the code.

I found this article, which i can get to work, but it saves the attachment to a folder on the local machine. I'd love to tweak this one a little to have it save to a document library rather than the local disk. The form submit the info to a sharepoint list, if i could get the attachment to attach to that list item that would be best, but if not, at least submit the attachment to a document library and have a way to link the two so that price quotes will be attached to the request form.

Here is the code i'm using that is working thus far:

XPathNavigator docXN = this.CreateNavigator();

XPathNavigator opnXN = docXN.SelectSingleNode

("/my:myFields/my:attachment", this.NamespaceManager);byte[] attachmentNodeBytes = Convert.FromBase64String

(opnXN.ToString());

// Position 20 contains a DWORD indicating the length of the

// filename buffer. The filename is stored as Unicode so the

// length is multiplied by 2.

int fnLength = attachmentNodeBytes[20] * 2;

byte[] fnBytes = new byte[fnLength];

// The actual filename starts at position 24 . . .

for (int i = 0; i != fnLength; i++)

{

fnBytes[i] = attachmentNodeBytes[24 + i];

}

// Convert the filename bytes to a string. The string

// terminates with \0 so the actual filename is the

// original filename minus the last character !

char[] charFileName = UnicodeEncoding.Unicode.GetChars(fnBytes);string fileName = new string(charFileName);

fileName = fileName.Substring(0, fileName.Length - 1);

// The file is located after the header, which is 24 bytes long

// plus the length of the filename.

byte[] fileContents = new byte[attachmentNodeBytes.Length - (24 + fnLength)];for (int i = 0; i < fileContents.Length; ++i)

{

fileContents[i] = attachmentNodeBytes[24 + fnLength + i];

}

// We now have an array of bytes (fileContents) which we can

// do what we like with. I'll write them to a temporary file

FileStream fs = new FileStream(@"C:\Temp\" + fileName, FileMode.Create);

fs.Write(fileContents, 0, fileContents.Length); fs.Close();
