I have run into the issue on DataSet.WriteXml method. Apparently, if any row in a column in the DataSet has a null value, the entire column/rows will not write out in the xml file using the method DataSet.WriteXml. So, as terrible as that bug is, I need to send the data another way. Does anyone have any thoughts?
I would like to pass xml document to a method in WCF service by client that server will get xmldocument,parse it and send back the xml response.What are best practice for thi?The xml document is conform to XSD so i would like to create managed type that represent the schema and then expose thatIf anybody has done it before or know any example please point it out so i can see it.

In Visual Studio 2005 I am following the steps to add a Web Reference to a web service.hings appear to go smoothly except for an error messae I am getting. Here are thesteps I follow along with the result.1. Right click on Web References folder and select "Add Web Reference..."2. When the dialog box appears I add the web service URL into the URL dialog box.The web service methods are then displayed in the dialog box with the links to each web service and a prompt to "Start Browsing for Web Service"However in the box to the right which is labeled "Web services found at this URL", there is an error messagewhich reads:There was an error downloading 'https://stage-serv/weatherQuote/WebService/weatherQuote.asmx
The underlying connection was closed: An unexpected error occurred on asend.Authentication failed because the remote party has closed the transport stream.I don't know what is causing this problem. I can reference this same web service on a productionserver just fine, but if I attempt to access it on the stagig server I get the message Ijust talked about.I am thinking that something is not configured on the staging server correctly.
I am a REST web service newbie, does visual studio, .NET, or some other nifty microsoft tool provide any easy way to auto generate classes to consume a REST web service? With REST services is there even a service definition like there is with SOAP (WSDL) beyond the printed documentation? There is a new service that I'd like to consume but they only wrote wrappers for PHP, Pearl, Ruby, and Java and have more or less said you are on your own with .NET. I could write it myself but I'd like to cut corners and save time wherever possible.
View 1 RepliesIs there a way to read and write files on a client's computer using a web based application? Basically I need to create a internal app that will take two input CSV files and convert it into an output CSV file that is written to the same location as the input files on the client's computers.
Since this is an internal app, I don't have to worry about security. I can easily write a C# app for this but I want to create a ASP.NET app (or any other format). I even looked into creating a HTA application.
I've been wondering how i go about writing a MembershipProvider that authenticates using a WCF Provider. At the moment i have a wcf service that will authenticate a username and password.
I can write my own Membership provider that will authenticate using WCF calls, thats no problem. What i want is to have the WCF as the actually provider.
Meaning in the web.config file i just put the WCF service as the MembershipProvider. Or is this not possible or not the way this is to be done.
A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
Is there a way (except for using JS on the html view) to tell asp.net to run a certain code on client side (instead of server side)?

View 1 RepliesWe are developing SOA based application using .NET 3.5 and WCF & WPF.
One common issue we are facing is mapping between WCF enum and WPF enums. We had to do mapping between WCF enums to WPF enums. Following is sample code
Switch(WCFServiceObject.Status)
{
Case WCFServiceStatus.Married[code]....
You can see that we have to do mapping WPF and WCF enums. Is there any easiest way to achieve this mapping without writing tedious switch statements? One way of doing this is using Dictionary, but apart from this, is there any good way? We have lots of enums for which have to do mappings.

I have recently converted all my applications to framework 4.0 and am very happy as a whole.
I have, however, run into a bit of a bind: i have exposed quite a few web services that have methods returning datasets.
Clients immediately started complaining that the order of the tables within the returned datasets were different. I investigated and can confirm that the webmethods are indeed shuffling the tables within the datasets. The order of tables in the method result are markedly different from the table order in the code before being returned.
My question is: is it possible to hard code the order of tables within the dataset being returned by a webmethod? I know that clients should, ideally, be referencing the tables via the table names, but that is - unfortunately - not the case in the really real world.
I am searching for a solution to pass a large dataset from visual foxpro(vfp) to a .net web service. The data is personal information such as names, address, phone numbers, etc. with 7 more columns containing id's and other parameters.
We tried cursor to xml dataset but the file size is very large. So my idea is to pass json formatted string. We need to accommodate up to 1 million rows of data
I found this solution on the web for json webservice. [URL] Can this work for such large datasets? Is there anything better suited for my situation
I found this class for VFP [URL] which promises to do what is needed as far as converting to json format. Should this work? Is there anything else I am missing here?
