PDF export will not work on browser enabled forms.

The code works perfectly, but is it possible to eport the PDF using the higher quality mode via code?

Does anyone know how to fix the issue of the export only showing up in portrait vs landscape?

 

It is not as simple as changing the print view, I have tried that. I have set page widths as well. Nothign works. Have heard it was an issue wehn SP2 came in... but that was a long time ago.

Hilary,

I can't thank you enough.  Your C# code for converting an Infopath form to PDF works perfectly.  The only problem I have now is that the PDF and XPS conversion loses most of my data and half of the form is cut off.

The only solution I can find is to have the form converted to MHT format.  I can do this both manually and by modifying your code to save it to my local drive and it comes out perfectly.  But that's not good enough for me.  I need to save the converted form to a MOSS SharePoint folder.  I can do this fine when I export as a PDF or XPS using your code so I know its not an issue with Full Permission and Signatures as I have those all enabled as necessary.

Here is what I have for exporting as a PDF.  This works fine with no errors.  I just lose half the information from the form.

//Declare our variables

string fileName;

XPathNavigator nameNode;

XPathNavigator nameNode2;

 

//Set the values. Replace "/my:myFields/my:textField" with the xpath to the field that has the value you want as the file name

nameNode = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field1", NamespaceManager);

nameNode2 = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field4", NamespaceManager);

fileName = nameNode.Value + "_" + nameNode2.Value +".pdf";

//Do the work -- notice we use the variable fileName as part of the path for the file.

this.CurrentView.Export(@"http://moss.mysharepoint.com/.../mycompletedforms/" + fileName, ExportFormat.Pdf);

 

Then I try to change a couple of points to convert the form to MHT like this:

 

//Declare our variables

string fileName;

XPathNavigator nameNode;

XPathNavigator nameNode2;

 

//Set the values. Replace "/my:myFields/my:textField" with the xpath to the field that has the value you want as the file name

nameNode = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field1", NamespaceManager);

nameNode2 = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field4", NamespaceManager);

fileName = nameNode.Value + "_" + nameNode2.Value +".mht";

//Do the work -- notice we use the variable fileName as part of the path for the file.

this.CurrentView.Export(@"http://moss.mysharepoint.com/.../mycompletedforms/" + fileName, ExportFormat.Mht);

 

Here are the errors I get.

 

System.Runtime.InteropServices.COMException
InfoPath cannot export the form.
   at Microsoft.Office.Interop.InfoPath.SemiTrust.View.Export(String bstrURL, String bstrFormat)
   at Microsoft.Office.Interop.InfoPath.SemiTrust.ViewObjectWrapper.Export(String bstrURL, String bstrFormat)
   at Microsoft.Office.InfoPath.Internal.ViewHost.Export(String fileLocation, ExportFormat format)

   at Microsoft.Office.InfoPath.Internal.ButtonEventHost.OnButtonClick(DocActionEvent pEvent)
   at Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent pEvent)

 

Like I said, I can change the export path to my local hard drive and it works perfectly for the MHT export.  I can also manually export the form using 'File - Export to.. - Web' and direct it to the SharePoint site and it works perfectly fine that way too.  I just need it to work when the button is clicked inside the form.

I certainly appreciate any help that you or anyone can give on this issue.

You could try creating a print view for your form that won't cut off bits on export.

Here's an MSDN page on the error you are getting. I'd try a try / catch around the line that does the export, and set a breakpoint on the catch so that you can get more detail on the error.

 

hi,

 I am facing a same issue, I am able to export and save PDF file into SharePoint Document library directly,

But, I am not able to export and save MHT file directly into SharePoint Document library when click on button.

Error :

at Microsoft.Office.Interop.InfoPath.SemiTrust.View.Export(String bstrURL, String bstrFormat)\r\n   at Microsoft.Office.Interop.InfoPath.SemiTrust.ViewObjectWrapper.Export(String bstrURL, String bstrFormat)\r\n   at Microsoft.Office.InfoPath.Internal.ViewHost.Export(String fileLocation, ExportFormat format)\r\n   at Formtemplate6.FormCode.SRApproval_Print_Clicked(Object sender, ClickedEventArgs e) in line 49\r\n   at Microsoft.Office.InfoPath.Internal.ButtonEventHost.OnButtonClick(DocActionEvent pEvent)\r\n   at Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent pEvent)"

Note : I am able to export and save MHT file in Local drive

 

Hi Hilary,

I am completly new to Infopath. I have added a submit button and made the changes as you have said in your post. But when I fill the form in the preview mode. I get the following error

 System.NotSupportedException
The given path's format is not supported.
   at System.Security.Util.StringExpressionSet.CanonicalizePath(String path, Boolean needFullPath)
   at System.Security.Util.StringExpressionSet.CreateListFromExpressions(String[] str, Boolean needFullPath)

Please help me.

Well, the error indicates that the path you are trying to export to is invalid. It would be impossible for me to know why without seeing the code. Have you tried running in debug?

Hi Hilary,

I changed the path in the code to make it simple and tried submitting the form again in preview mode again, I got the following error.

System.NullReferenceException
Object reference not set to an instance of an object.
   at LCV_REQ.FormCode.Print_Clicked(Object sender, ClickedEventArgs e)
   at Microsoft.Office.InfoPath.Internal.ButtonEventHost.OnButtonClick(DocActionEvent pEvent)
   at Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent pEvent)

I am not able to understand what the error is. If you want to see the what should I do to send you the code..as I said I am completely new to infopath.

The following is all I have in the section which I believe is the code section of InfoPath.

Imports Microsoft.Office.InfoPath

Imports System

Imports System.Windows.Forms

Imports System.Xml

Imports System.Xml.XPath

Imports mshtml

 

Namespace LCV_REQ

Public Class FormCode

' Member variables are not supported in browser-enabled forms.

' Instead, write and read these values from the FormState

' dictionary using code such as the following:

'

' Private Property _memberVariable() As Object

' Get

' _memberVariable = FormState("_memberVariable")

' End Get

' Set

' FormState("_memberVariable") = value

' End Set

' End Property

' NOTE: The following procedure is required by Microsoft Office InfoPath.

' It can be modified using Microsoft Office InfoPath.

Private Sub InternalStartup(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Startup

AddHandler DirectCast(EventManager.ControlEvents("Print"), ButtonEvent).Clicked, AddressOf Print_Clicked

End Sub

Public Sub Print_Clicked(ByVal sender As Object, ByVal e As ClickedEventArgs) 'Declare our variable

Dim fileName As String

Dim nameNode As XPathNavigator

'Set the values. Replace "/my:myFields/my:textField" with the xpath to the field that has the value you want as the file name

nameNode = MainDataSource.CreateNavigator().SelectSingleNode("test", NamespaceManager)

fileName = nameNode.Value + ".pdf"

'Do the work -- notice we use the variable fileName as part of the path for the file

Me.CurrentView.Export("C:\" + fileName, ExportFormat.Pdf)

End Sub

 

End Class

End Namespace

Sorry to bother you so much, your help on this is much appreciated.

Nitin. 

 

In the code sample, we were using the value of a node for the file name. In your code, you have:

nameNode = MainDataSource.CreateNavigator().SelectSingleNode("test", NamespaceManager)

Which will most likely result in "nameNode" being null - do you have a form field you'd like to use for the name?

For testing purposes, you could just change this line:

fileName = nameNode.Value + ".pdf"

To a value for the file name:

fileName = "test.pdf"

for example.

using Microsoft.Office.InfoPath;
using System;
using System.Windows.Forms;
using System.Xml;
using System.Xml.XPath;
using mshtml;
using System.IO;
using System.Windows;

use the above name spaces and add the following dlls to your solution

System.Windows.Forms.dll

microsoft.mshtml.dll ---- Download from the microsoft site

then it will work

 I've had the exact same problem.  I don't see anywhere in the API to set the resolution to the "Standard"? 

 

              finaldoc.Save(p + '\\' + splitatlevel.Last() + "_Final.xml");
 
              formControl1.Open(p + '\\' + splitatlevel.Last() + "_Final.xml");
              formControl1.XmlForm.CurrentView.ForceUpdate();
 
              Application.DoEvents();
 
              MessageBox.Show(splitatlevel.Last());
 
              formControl1.XmlForm.CurrentView.Export(p + '\\' + splitatlevel.Last() + "_Final.pdf", Microsoft.Office.InfoPath.ExportFormat.Pdf);
              formControl1.Close();

Anyone else have any API or COM insight on programmatically setting the pdf quality?
