InfoPath Dev

I have a problem to recover the value of a field.  I have  a exeception : “ The exception Xpath is not managed by the user code.”
(The manager namespaces or XsltContext is required. This request has a prefix, a variable or user-defined function.).  I use Visual basic and InfoPath 2007.

Dim  xmlDoc  as XmlDocument

Dim Node as XmlNode  

Dim sVar as String

Node =xmlDoc.DocumentElement.SelectSingleNode("/my:mesChamps/my:CODE_RISQUE")

sVar=Node.value

Please help me

Hello,

In your code you are not initializing for ‘xmlDoc' variable. Just you declared as variable without initializing any value. As per the code ‘xmlDoc' is null then we much not able execute next step is ‘xmlDoc.DocumentElement' property.

Check once your code.

It looks like you want to be using code more like this:

 Dim Node as XPathNavigator
 Dim sVar as String
 Node = MainDataSource.CreateNavigator().SelectSingleNode("/my:mesChamps/my:CODE_RISQUE")
 sVar=Node.Value

I think the error is in the path xpath : /my:mesChamps/my:CODE_RISQUE

Please help me 

Are you using InfoPath 2007? If so, you can right click the field in the data source task pane and copy the xpath....

I solved the problem using the following code:

Dim Node as XPathNavigator
 Dim sVar as String
 Node = MainDataSource.CreateNavigator().SelectSingleNode("/my:mesChamps/my:CODE_RISQUE", Me.NamespaceManager)
 sVar=Node.Value

Thanks Jimmy !
