InfoPath Dev

I'm a newbie in Infopath.

I've created a small webservice with Visual Basic.Net for comunicate with an Access DB.

In the VB Code there is a Type called "Census" like this:

Public Class Census
   Public ID as Int32
   Public DateBirth as Date
   Public Name as String
End  Class

If I look to the WSDL it seems like this:

<s:complexType name="Census">
   <s:sequence>
      <s:element minOccurs="1" maxOccurs="1" name="ID" type="s:int"/>
      <s:element minOccurs="1" maxOccurs="1" name="DateBirth" type="s:dateTime"/>
      <s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string"/>
   </s:sequence>
</s:complexType>

I would like that minOccurs for ID and DateBirth is 0 not 1 so that in Infopath I'm not obliged to insert a value for it. Alternatively I need a way to obviate this problem

How can I do this??

Thanks for replying and excuse me for my bad english.

Hi fratellino, Welcome tot he Board!
Minoccurs "0" does not mean that it is a compulsory field, It means that the total number of occurences of that element can be "0" i.e, the element can be or Cannot be there in the XML.
Usually "integer" and "datetime" fields are made compulsory in the Infopath, to override this you can have "nillable" attribute set on Elements with "integer" and "DateTime" types.
So your element can look like this
<s:element minOccurs="1" maxOccurs="1" name="ID" type="s:int" nillable="true"/>

and you need to set "xsi:nil='true'" in xml
<DateBirth xsi:nil="true"></DateBirth>.

Hope this helps!

Thanks for replying.

the xml is not generate by me, but auto-generated by the .asmx file builded with Visual Basic.net
So I can't edit this values, or if I can I don't know how.

You can edit Schema file and have a "nillable" attribute on it. You can also add "xsi:nil" attribute to a node. Here is a way how to do it,

private void setNil(IXMLDOMNode oNode) //oNode is your Node for which you dont want to enter a value
{
IXMLDOMElement oElement = (IXMLDOMElement)oNode;
if(null != oElement.getAttribute("xsi:nil"))
{
// Create xsi:nil attribute with the proper namespace.
IXMLDOMAttribute oNil = (IXMLDOMAttribute)oNode.ownerDocument.createNode((int)DOMNodeType.NODE_ATTRIBUTE, "xsi:nil", "http://www.w3.org/2001/XMLSchema-instance");
oNil.text = "true";
//Set the "xsi:nil" attribute to the node
oElement.setAttributeNode(oNil);
}
}

Hope this helps!
