hi everyone, i'm getting this error: "There was an error generating the XML document" when i try to serialize a class. it works for other classes except for classes like these : public class studentList() { public student[] students //has only one member and it is an array of another class } i didn't get much info from stackTrace which says: at System.Xml.Serialization.XmlSerializationWriter.WriteTypedPrimitive(String name, String ns, Object o, Boolean xsiType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write3_Object(String n, String ns, Object o, Boolean isNullable, Boolean needType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write228_studentRegistration(String n, String ns, studentRegistration o, Boolean isNullable, Boolean needType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write5_studentBody(String n, String ns, studentBody o, Boolean isNullable, Boolean needType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write1_studentMessage(String n, String ns, studentMessage o, Boolean isNullable, Boolean needType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write242_studentMessage(Object o) my question is, is it the class? this is a project at work. i was given these schema files and just generated classes from those schemas to use for the project. i already did searching online and i found one that it says it is a problem on the class. let me know please. i will really appreciate your reply. thanks

hi, thanks for your reply. i didn't post the code since it's very long. basically i only used BeginSend()(tcp socket) method to send the message and i get to this part of the other application : //------WebService file-------- public string EndSendMessage(System.IAsyncResult asyncResult) { object[] results = this.EndInvoke(asyncResult); return ((string)(results[0])); } //---Form.cs file--------- MyWebService ws = new MyWebService(); //other code here... string str = ws.EndSendMessage(); //<---- string is null I've been looking around for a code that works like this but i can't find one. Is it really possible to send a message from a TCP socket to a Webservice? :confused: Thanks.

hi everyone, i'm developing 2 applications that can communicate to each other. application1 is using a tcp socket to send a message to application2. application2 should receive the message through its webservice. now, my problem is i'm not getting the message in application2. i tried running ethereal to check the packets and i can see that the message is going to the computer where application2 is running but i'm getting a Null reference exception on application2. i tried using stacktrace but it's only giving me the line where the null reference occured no further information. so, i need advise what's going on. why am i not getting the message from the application? i have been working on this problem for a week now. so, please advice. thanks.

hi everyone, i'm developing an application that will work like a web service. my problem is I don't know how to generate an http chunked response correctly. on the http chunked response, i'm getting a wrong size for my data size or chunk size. so i'm not sending the whole message. please advice :*(

I believe I followed the instructions. I did the steps in: To install the sample databases and samples after Setup. But then when I tried to register the AdventureWorks Database, in the New Server Registration Dialog Box, I clicked on the AdventureWorks (in the Connect to Database listbox), then I clicked TEST button, I'm getting an error says: "Cannot open database requested in login...." So I thought it was installed but not attached, so what I did I used the ATTACH context menu in the Database, i looked for the .mdf file, but I'm still getting an error. But I was wondering why when I installed AdventureWorks it didn't go to this path: n:\Program Files\Microsoft SQL Server\MSSQL.n\MSSQL\Data. It when here: n:\Program Files\Microsoft SQL Server\90\Tools\Samples \AdventureWorks OLTP. And I'm getting an error when i'm trying to attach it:confused: hope this makes my problem clear and hope you can help me. Thanks!

hi everyone, i'm trying to install the sample database AdventureWorks I followed the step-by-step in the tutorial book (installing after the setup). but i don't know why i cannot make a connection on it. Anyone here knows how to workaround this problem. I will appreciate any help!:doh:

hi everyone, i'm new with this software. i have installed it and i think i was able to install it successfully. but i'm wondering it seems to me this 2005 version was not installed since i don't see any difference between this and the 2000 version. when i opened the "Books online" it says there Ms Sql Server 2000. that does mean the 2005 developer edition wasn't installed? I will really appreciate any help!
