I'm not very good with web services and I'm dealing with one developed internally in Java. This web service requires a Header element named Token with a value (an encrypted string). I've been able to add this "Token" but the service doesn't accept it. This is the request xml my proxy calls generates (proxy class built with WSDL.EXE and modified to accept a SoapHeader external class I wrote to add Header to request):
And this is what the web services wants (this is a xml request made by a java tyest client): <soapenv:Envelope> <soapenv:Header> .....
This is the code I wrote: Imports System.Web.Services Imports System.Web.Services.Protocols <System.Xml.Serialization.XmlRoot(Namespace:=[WSDL NAMESPACE])> _ Public Class TokenHeader Inherits SoapHeader [Code] .....

I am trying to make an application that will take the information entered into the program and generate a quote sheet using Microsoft word. Right now I am having trouble creating tables in the word document. The user can choose to quote between 1 to 4 different products. If 1 product is quoted, then it will create a 6x3 table. If 2 products are quoted, then it will create a 6x5 table with the 3rd column separating the 2 products. If 3 or 4 products are quoted then it will create another table under the first table and follow the same rules as the first table. The program works perfectly if I quote 3 or 4 products but when I try to quote 1 or 2 products then it results in an error.
Dim QuoteNumber As String Dim RowsNeeded As Integer QuoteNumber = NumberOfProducts.Text

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Public Structure myStruct Public element1 as string Public element2 as integer Public element3 as boolean

i am using VB. net 2008. I am having a hard time using this code: ("L:SWPPPSWPPPBookMerge.doc") what is the shortest method that the system will search for the document without placing the document address.

Is there a way to prevent this truncation under Windows Server 2008?Mary Leathem
