InfoPath Dev

Hi All,

I am using infopath 2007. 

In my sharepoint form library, I have an infopath form which has an attachment field.

This is my requirement --> On button click, I need to programmatically attach a zip file to that attachment field.

I know attachments in infopath are stored in base64 encoded string.

Till now I am successfully able to load the zip file into byte[] array and convert it into base64 string. This is the code snippet:

                string strFilePath = "C:\\Test.zip";
                FileStream fs = new FileStream(strFilePath, FileMode.Open, FileAccess.Read);
                BinaryReader br = new BinaryReader(fs);

                byte[] data = new byte[fs.Length];
                fs.Read(data, 0, data.Length);
                fs.Close();

                string strBase64 = Convert.ToBase64String(data);

 After this how do I set the value of infopath attachment field as strBase64??

 Is this is the right approach or am I going wrong??

Need help.

 Thanks,

Jaimin

Hi there:

First off, please check out this KB article for information on encoding and decoding. It will help you with things like setting the file name. To select a node and set the value, you can use the following, changing the xpath to point to your node:

string xpath = "/my:myFields/my:field1";
XPathNavigator node = MainDataSource.CreateNavigator().SelectSingleNode(xpath, this.NamespaceManager);
node.SetValue("value");

 thanks for the help. I'll try this and let you know if it works or not.

Thanks,

Jaimin

 Thanks Hilary.

 file attachment is working now.
