many posts about the security risks of app.config file...ncrypted or not... for storing the connection strings of a remote database.OK! I agree with this... but... how can i make a VB.NET Application to connect to my database thru WebService or WCF as long my server is Centos with MySQL ? How can i make the connection strings of MySQL Connector to work with WebServices or WCF ? I did not find any solution for this problem.

I use VB in Visual Studio 2008 Pro. I've created a few solutions using the Crystal Reports tools. I found them easy to work with & easy to do things, (export to different formats, refresh reports, write an automated service that ran & saved reports, etc...)Is CR in VB 2010? If so - which version of VS 2010 do you need to buy to get it?OR - is the reporting services in VS a suitable replacement? Is there a viewer / preview like the CR tools? Can you create a standalone app to refresh reports & export them to different formats? Which version of VS 2010 would I need to purchase to get these?At home - I use Win 7 media centre (a fantastic piece of software). Are there any development 'goodies' in Visual Basic 2010 for Win 7 Media Centre?
View 2 RepliesI'm working on a application which suppose to work as a interface between multiple applications. as a example, one PBX system sends me data via TCPIP or COM ports and I manipulate it and send to PMS application. likewise PMS also send me data which I need to send back to PBX system.By query is, I don't have a fix number of communication interfaces and it can go up to 8 - 10 or may be more and they should work independently (should be able to switch off communication at any time in any interface).
In this situation, I cannot handle everything in one service or two since I don't know how many interfaces going to be. So I'm thinking a way to create services dynamically such as when user create a new interface in application it automatically creates the windows service on server or pc.I don't really need to create services remotely since my application will install only in one pc or a server and system administrator will access the server for the configurations.
I've set up an application that runs as a service, auth'd as LocalSystem. One of it's functions is to establish the logged in windows user's username.All I'm getting with the following is either the SID or username of the user (localsystem) running the service.
my.user.name
WindowsIdentity.GetCurrent().Name
WindowsIdentity.GetCurrent().User

What is ado.net synchronization services and how to use these services
View 1 RepliesAt the moment we're are considering writing a number of .Net web services to export/import data between sites. There are various different types of data involved, relating to multiple database tables. I could write various web services to receive the data being sent, for example
ImportSomeRecord(field1, field2, field3)
ImportSomeRecord2(field1, field2)
ImportSomeRecord3(field1, field2, field3, field4, field5)
and so on...
There could be about 40 of these services, and it's also possible that the fields may change i.e. new fields may be added. The client would be a VB6 application that would call the remote web service, and let that web service update the remote database. The web services will be written in VB.Net 2008.
Would it be advisable to replace all these web services with a single generic service e.g. ImportRecords(recordtype, blobofdata). I think this can be done in theory by just passing an XML string as the blob of data and letting the web service unravel this depending on the record type, but is there actually any advantage to this, and is it good practice to do so? I've read somewhere that passing XML chunks in this way, as a single parameter, isn't recommended, and I can see this also seems to be somewhat contrary to standard web service usage in that in effect I'm bypassing the web service definition.
I created an application using the Exchange Web Services, everything works fine, but after running 3 or 4 times, I suddenly get the error:

View 3 RepliesI'm mainly a VB6 developer, but am currently trying to write a web service using VB.Net to allow for communication between our product and a third-party. The third-party software will invoke our web service to update various data.I've read up various things on how to do this, and have successfully generated a prototype web service. What I'm now concerned about is how to do this properly. Our clients want us to provide the WSDL and XSD for our web service, so they can implement it on their end, so I want to make sure I get it right. Therefore, I have the following assumptions/questions:The web service will receive various fields that should be updated. To keep this flexible, I thought that this could be a single XML parameter. I'm guessing this is why our clients want the XSD. Is this assumption correct? Is it good practice to pass an XML input parameter?I created a simple class with a sample of the fields that should be updated (Title, Address1, Address2 and so on) then generated an XSD from that using XSD.Exe. This made me think - should my input parameter be an instance of this class, rather than an XML document based on the XSD?
For example, the fields to be updated relate to client data. There are many possible fields that can be updated, but only a few will probably be updated at a time. Clearly, I don't want a method with 40 parameters for each possible field, and I was also asked to only provide a single method. My idea was therefore to have a parameter naming the fields to be updated, and their values. It seemed sensible to use XML for this parameter. My assumption regarding the request from our clients for the XSD came about so that we can make sure that the XML parameter will only include valid fields. But at the same time, I generated an XSD using Visual Studio based on a sample class I created. But now I'm not sure which is best to use i.e. either:
a) XML: cliData As Xml.XmlDocument: Appears in WSDL, but how would I generate an XSD to make sure the XML is valid? Manually?
b) Class: cliData As ClientData: Serialised in WSDL so each field appears as a separate element. Presumably no need for an XSD, but I don't think this gives me the option to only includes a few fields, and isn't this equivalent to having loads of parameters?
c) String: cliData As String: Pass in some sort of string, unravel it manually, but then no validation.
I initially planned to return the status of the web service (e.g. "OK" or some failure message), though I've seen reference elsewhere to SOAP Faults. There were some links to an MSDN article discussing this, but the links seemed to be broken.
I've converted a 2005 project to 2010. As I was debugging some issues I noticed that my compiles didn't seem to change anything so I deleted the bin directory and recompiled. Now all of my Web Services "ServiceName.asmx.vb" are no longer in the assembly and when I try to run them in the debugger, I get the following error:
Could not create type 'MyWebService.MyNamespace.MyService'.
I have verified that the Class and Codebehind are correct in the 'MyService.asmx' file.
I have verified that the MyService.asmx.vb file is marked to Compile and that the asmx file is Content.
How to retrieve data from database using Web services on VB?
View 5 RepliesI am writing web services with VB.NET (2.0). The client side will use different technologies such as Java and Siebel. So, if I write asynchronous web services, is it possible for different platforms to consume them? I know it is quite easy with a consumer having .NET platform, but not sure for different platforms. Is it enough for them to have asynchronous ability, or should it be a similar platform?

I am getting the following error when I add a service references that points to a web service.
'System.ServiceModel.XmlSerializerFormatAttribute' is not accessible in this context because it is 'Friend' in the Reference.vb file.
I have not gotten it in other projects that I have done that point to the same web service. I have recently add some code that I downloaded and cleaned up the errors in to my project and this seems to be what broke it. This code uses several new features that I am not familiar with, mainly the "Friend" declaration and also uses name spaces in the code it self. Also I converted the code from C# using an utility that I downloaded, that untility was not 100% in it's conversion, hence the clean up that was needed.

I am working on a system that calls several different web service to integrate in to a 3rd party system. each one of these web service contains a object called RetailerContext which is a type of security object that is required to get and set data.
My problem is the example code I was give in a document says you should crate a function called GetRetailerContext that set up the object for you, but because the object is defined in each of the web services that I have referenced the compiler tells the that RetailerContext is ambiguous. is there a way round this or do I have to write a GetRetailerContext for each of the web services?
Private Function GetRetailerType(securityInfo) as RetailerContext
Set up object

I have a working WCF, it is written in VB. I need to host it in Windows Services on a remote server. I cannot use IIS (they uninstalled after I had it installed). Specs are to host in Windows Services, the only way I can get around that is to quit.
[Code]...
I've created a WCF service and, with help of others from this site and the department I work in, the WCF service is running as a service on my development machine. Tested it with a console app and it works.But, it's not supposed to be on my development machine. It needs to be on a different server.This is difficult because the server it is supposed to reside on DOES NOT have Visual Studio installed on it.So I cannot run the VS 2008 Command Prompt with installutil to run the WCF service as a service on that server.

The ticket object is located in the My.Objects namespace. For each subsequent call in My.Service1 and My.Service2 you have to pass in the security ticket to authenticate the call. The issue I am having is that instead of the client (a .net one for now but Java and others in the future) seeing one My.Objects.Ticket the references are resolving as My.LoginService.Ticket, My.Service1.Ticket, and My.Service2.Ticket. When the client tries to pass the object retrieved during login to any other function it is receiving an object mismatch error.How can I make each service resolve objects to the My.Objects namespace?
