I've run into numerous articles stating that the following code will work in VB.NET. Well it does NOT work for me.
'-- DOES NOT WORK IN VB.NET
Dim xmlDocReq As New MSXML2.DOMDocument40()
xmlDocReq.async = False
xmlDocReq.resolveExternals = False
xmlDocReq.setProperty("ServerHTTPRequest", True)
xmlDocReq.load(Request) **** error: parameter is incorrect *****
The code below is tested and does work in VB.NET. The objective is to load and pass an XML document object from a sending page to a receiving page, and back (basically an echo). Let me know if you have any questions.
--------------------------------------------------
SENDER (Called in Sub Page_Load...)
--------------------------------------------------
'Set Receiving page
Dim strURL As String = "http://localhost/DevCitrus/ImportXML/ImportXMLRecieve.aspx"
'Set path of xml file to pass via HTTP
Dim xmlPath As String = "C:\TestXML\Manifest.xml"
'Send XML document to receving page and print result
Try
Dim xmlDoc As New MSXML2.DOMDocument40()
Dim xmlHTTP As New MSXML2.ServerXMLHTTP40()
'Load xml doc
If xmlDoc.load(xmlPath) Then
'Set method, url, async
xmlHTTP.open("POST", strURL, False)
'Send XML document
xmlHTTP.send(xmlDoc.xml)
'Set content type
Response.ContentType = "text/xml"
'Output xml result
Response.Write(xmlHTTP.responseText)
Else
Response.Write(xmlDoc.parseError.reason)
End If
Catch ex As Exception
Response.Write("<MANIFEST><catchError>" + ex.Message + "</catchError></MANIFEST>")
End Try
--------------------------------------------------
RECEIVER (Called in Sub Page_Load...)
--------------------------------------------------
'Set Content tpe
Response.ContentType = "text/xml"
'Create xmlDoc
Dim xmlDocReq As New MSXML2.DOMDocument40()
xmlDocReq.async = False
xmlDocReq.resolveExternals = False
xmlDocReq.setProperty("ServerHTTPRequest", True)
Try
If xmlDocReq.load(Request.BinaryRead(Request.TotalBytes)) Then
'Return echo of loaded XML doc
Response.Write(xmlDocReq.xml)
Else
Response.Write("<MANIFEST><parserError>" + xmlDocReq.parseError.reason + "</parserError></MANIFEST>")
End If
Catch ex As Exception
Response.Write("<MANIFEST><catchError>" + ex.Message + "</catchError></MANIFEST>")
End Try
