Hi,

I bet the XPath is not right. Try this first:
Start a new blank InfoPath / VB.Net project
Add 1 field (string), called: GrpName.
Drop a button on your form and add that line of code:
<InfoPathEventHandler(MatchPath:="CTRL1_5", EventType:=InfoPathEventType.OnClick)> _
Public Sub CTRL1_5_OnClick(ByVal e As DocActionEvent)
thisXDocument.DOM.selectSingleNode("/my:myFields/my:GrpName").text = "test"
End Sub

Once you you get that working, go back to your form and right click on your GrpName field in your schema:
Go the Validation and Event Handlers Tab
Select the OnBeforeChange Event
Click Edit.
The MatchPath will give you your exact XPath.
Use that, it should help.

Regards,

Franck Dauché

Exactly. Tried and got similar error

System.NullReferenceException
Object reference not set to an instance of an object.
at InfoPathProject1.InfoPathProject1.New_OnClick(DocActionEvent e) in C:\Documents and Settings\kkaylor\My Documents\Visual Studio Projects\InfoPathProject1\FormCode.vb:line 61
at Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent pEvent)

Public Sub New_OnClick(ByVal e As DocActionEvent)
Dim myField As String

myField = "Hello World"
thisXDocument.DOM.selectSingleNode("/my:myFields/my:GrpName").text = myField

End Sub

Hi,

Assuming that GrpName is a string in your schema, try:
thisXDocument.DOM.selectSingleNode("/my:myFields/my:GrpName").text = myField

Trying to pass a string to a field on my infopath form triggered by a command button , click.

Keep getting an error saying "Reference to undeclared namespace prefix: 'myFields'."

Here's the code :

<InfoPathEventHandler(MatchPath:="New", EventType:=InfoPathEventType.OnClick)> _
Public Sub New_OnClick(ByVal e As DocActionEvent)

Dim myField As String
myField = "Hello World"
e.XDocument.DOM.selectSingleNode("//myFields:GrpName").text()=myField

End Sub
