Hello. I had the same issue & used your suggestion to make it Full Trust. After doing that, I started getting different errors. Note, this is me implementing an msdn example.

Any help is GREATLY appreciated.

This is my new post with full details: http://www.infopathdev.com/forums/p/19815/68720.aspx#68720

Hi Patrick,

Thanks for your great response.

I've been playing with Wong-A-Ton's code "How to loop through items in a repeating table...".

I tried it on a box with .net framework 3.5 and infopath; got the "Request failed" security error.

I stuck the code into a visual studio project. At first got another error ("Microsoft Office InfoPath does not recognize some or all of the

command line options."). Unbelievable!

I had to remove sp1 for Office 2007 from the box and finally got the code working.

Hoops galore!

(sorry about the rant)

Open the form in the Infopath Designer and choose Tools->Form Options and click Security. Change from default setting (Domain Trust) to Full Trust.You'll have to provide a digital certificate (or create an MSI). The implication is that deployment costs will be greater since you'll have to tell people to accept your digital certificate (or install the MSI) and the security will be less - the form can do anything (which isn't a big deal if you're the sole author of the form). In general, Full Trust is a bad idea. 99% of all forms do not need to be full trust. Too bad about the Microsoft .NET bug. We'll send them an e-mail complaining again.

Hi,

Please excuse my stupid question.

How would I "make the form full trust"?

What are the implications of this?

Thanks in advance.

As the posts above yours indicate, this is an issue when using InfoPath with .NET 3.5 and the only known workarounds at the moment are to downgrade to .NET 2.0 or make the form full trust.

Could you tell us what version of the .NET framework you have installed?

hi,

I am having the same problem, while running the code given below

            string xpath = "/my:myFields/my:group8/my:Name";
            XPathNavigator field = MainDataSource.CreateNavigator().SelectSingleNode(xpath, NamespaceManager);
            field.SetValue("Ram");

I get the following error

Request failed.
at Microsoft.Office.InfoPath.MsxmlNavigator.IsValidNode(MsxmlNode test)

i have checked the name in the xml file also. everything is correct.

Can any one help to solve this issue

Thanks,

System restore should have done it for you (provided you have a restore point before .NET 3.5 was installed). You cannot just accept the default restore point (which was the last one created). You must choose a different one--go through the list of available ones and locate one that was BEFORE .NET 3.5 was installed.

Assuming you already did this, and didn't just accept the default (previous) restore point, then I don't personally know of another option--though you should definitely ask around before attempting to rebuild your computers. You might also want to contact Microsoft Support directly to see if this is a known limitation or whether there's just some setting you can change or something.

I have not seen such an issue personally. There could be some other conflict involved.

To revert back without needed to reformat, use System Restore (a feature of Windows Vista and XP).

Ok it is a definitely a .net 3.5 issue because i just use a laptop computer which has no .net 3.5 but has 3.0 and all my forms work fine. Uninstalling .net 3.5 does not solve that problem. Anu suggestions or seen anything like that before?

Ok, in order to see what is going on i just create a new form with only one text box named tbox and one button.

The code for the button is below;

XPathNavigator eray = MainDataSource.CreateNavigator();

string asd;

asd = eray.SelectSingleNode("my:myFields/my:tbox", NamespaceManager).Value.ToString();

MessageBox.Show(asd);

Ok, it should simply show the letters or numbers which i entered the text box. However i get exactly same problem. I remember now this happened before to me after i installed visual studio 2008 express on my computer and i was suspecting to .NET 3.5. Even if i uninstall .net 3.5 , it did not solve the problem and i reformat the machine and it went back to normal. I just figure out that last week all the computers installed .net 3.5 from mic update. I already tried to uninstall .net 3.5 from one computer but i have same problem. So i do not know it is a bug or something. Any ideas?

The failure is coming from: root.SelectSingleNode("my:myFields/my:eName", NamespaceManager).Value.ToString()

The failure is that the node is invalid. Are you sure that it is "eName" and not just "Name"?

Otherwise, I suggest looking at an XML dump of the form causing the issue to see if the field is actually there.

If the field is there, then make sure NamespaceManager handles the "my" namespace for "root" (which ti should if "root" is the main data source).
