Submitting a Form Programmatically
In InfoPath, you can set up a form template so that the users are able to submit the
data in their form directly to an HTTP location, a database, or a Web service. If this
feature is enabled, the Submit command is available on the File menu in the Fill Out
Form mode. To programmatically specify the URL for submitting the InfoPath form
to the SharePoint form library, add a script to the form’s OnSubmitRequest event
handler, as described in the following procedure.
1. In InfoPath design mode, open the form template.
2. On the Tools menu, select Submitting Forms.
3. Select Enable submit, select Submit using a custom script from the Submit
drop-down list box, and then click OK to open the Microsoft Script Editor.
4. Add a script similar to the following to the OnSubmitRequest event handler
for the form:
function XDocument::OnSubmitRequest(eventObj)
{
// If the submit operation is successful, set
// eventObj.ReturnStatus = true
var blnSubmitSuccess = false;
var fFileExists = false;
// Specify the URL of the file you want to submit here.
var strUrl = “http://MyServer/MyFormLibrary/MyForm.xml";
try
{
// Create an XMLHTTP object to transport the file.
var objXmlHttp = new ActiveXObject(“MSXML2.XMLHTTP.5.0”);
// Attempt to open to a form using the specified URL to
// check if a form with the same name already exists
// in the form library.
try{
objXmlHttp.Open(“HEAD", strUrl, false);
objXmlHttp.Send();
fFileExists = true;
}catch(e)
{
XDocument.UI.Alert(“Submit failed due to the following error
.\n\n” + ex.number + “ - “ + ex.description + “\n\nThe file already exist”);
fFileExists = false;
}
// If no form at the same URL has been found, proceed
// to submit. If you need logic to replace the previous
// file, you can call
// objXmlHttp.Open(“DELETE", strUrl, false) to delete
// the form from the form library before proceeding.
if (objXmlHttp.Status == 404 || !fFileExists)
{
// Submit the form to the form library.
objXmlHttp.Open(“PUT", strUrl, false);
objXmlHttp.Send(XDocument.DOM.xml);
