Re: Accessing nodes of secondary datasource

Hi swathip. Thanks for your help. I solved the problem.

I had used selectSingleNode("/dfs:myFields/dfs:dataFields/d:UserAccess/@useracc").value in the beginning and many other combinations. But my namespace definition was going all wrong. I changed the namespace definition.

FROM
XDocument.GetDOM("UserAccess").setProperty "SelectionNamespaces", "xmlns:ns1=""http://schemas.microsoft.com/office/infopath/2003/ado/dataFields"""

TO
XDocument.GetDOM("UserAccess").setProperty "SelectionNamespaces", "xmlns:d=""http://schemas.microsoft.com/office/infopath/2003/ado/dataFields"" xmlns:dfs=""http://schemas.microsoft.com/office/infopath/2003/dataFormSolution"""

And then I could use the following to access useracc field from the secondary datasource.

user_acc = XDocument.getDOM("UserAccess").selectSingleNode("/dfs:myFields/dfs:dataFields/d:UserAccess/@useracc").value

Thanks again.

Hi,

Try the following code line.

user_acc = XDocument.getDOM("UserAccess").selectSingleNode("write the total xpath of the user acc").value

the total xpath may be like ‘myFields/ dataFields/ns1:UserAccess'

Also once verify any prefix need to add before the myfields and dataFields.

Or use the following one.

user_acc = XDocument.getDOM("UserAccess").selectSingleNode("//ns1:UserAccess").value

Accessing nodes of secondary datasource

Hi. I went through some very informative links on namespece definitions and secondary datasources.

I am using Infopath 2003 SP2, Access 2003 and prg language is VBScript. I have a form where I need to access a secondary datasource named UserAccess to find the access of the user who logs in.
The secondary datasource looks like below:

myFields
dataFields
d:UserAccess

I have added the following namespacesDefinition in the form which I got in the properties of UserAccess.
XDocument.GetDOM("UserAccess").setProperty "SelectionNamespaces", "xmlns:ns1=""http://schemas.microsoft.com/office/infopath/2003/ado/dataFields"""

The code looks like below:

Sub btn_Test_OnClick(eventObj)
       dim orig_sql, criteria, new_sql, user_acc
       orig_sql = XDocument.DataAdapters("UserAccess").Command
        msgbox(orig_sql)
        criteria = "SNS002"                              ' hardcoding only for testing
       new_sql = orig_sql + " where userid = '" + criteria + "'"
       msgbox(new_sql)
        XDocument.DataAdapters("UserAccess").Command = new_sql
       XDocument.DataAdapters("UserAccess").Query()
       user_acc = XDocument.getDOM("UserAccess").selectSingleNode("ns1:useracc").value
       msgbox(user_acc)
End Sub

The line of code where I try to access the value from useracc column throws an error 'Object required'. I have tried using:
XDocument.getDOM("UserAccess").selectSingleNode("/ns1:useracc").value
XDocument.getDOM("UserAccess").selectSingleNode("/ns1:@useracc").value and many other combinations but nothing helped.

What am I doing wrong? Is the namespacesDefinition wrong? I intend to use the same logic to check whether a user is entering duplicate data in a column which has unique key constraint.

Please help!!
