So why would a Web Service be starting an interactive process on the server?
Since services run under they're own desktop, the window is getting created, just on a desktop that is hidden from view.

Because the web service is only a wrapper to business logic process and I want to see some trace messages from the BL-process. Store this messages in event log or a log file is not a solution for me.
Please don't ask why I do it so, because there is no other way. Please give me hints, tricks or ideas to solve my problem. It's not possible to change the infrastructure.

Keep that up and you'll be completely on your own in no time.
Since your ASP.NET WEb Service cannot show a user interface on the server hosting it, you'll have to supply a UI some other way, like a normal Windows Forms app running a custom TraceListener exposed as a singleton class inside a WCF Service.
Well, a rather convoluted solution would be to create your own implementation of a TraceListener, setup as a singleton, in a host application that shows all incomming trace messages. This trace listener would be exposed through the host as a remotable object, or do the same thing as a WCF service hosted in a Windows Form or Console application.
In your Web Service Global.asax page, in possibly the Application_Start, Session_Start, or Application_BeginRequest handlers, you'd get the reference to the custom trace listener, add it to the Trace.Listeners collection in your Web Service, handle the call and output your trace messages.
The custom TraceListenerwould output any messages to a TextBox, Console window, log to a file, ..., whatever you want.
The downside is that this is a convoluted solution. The up side is that is lets you deploy your web service to multiple servers and still log all trace messages to a single window on a single monitoring workstation.

I'm using visual studio 2005. I designed a user-defined DataSet using the DataSet designer. I inserted a table and wanted one of its columns to be hidden (not emitted when the DataSet is serialized to XML). The designer by default sets the column mapping to <i>Element</i>. I found no method in the designer (or the property sheet) to set the column mapping. I tried to override this setting by hand editing the .cs (, I'm using c#,) file generated by the designer and changed the mapping type (, the fourth parameter,) in the DataColumn constructor to <i>Hidden</i>. However each time I make any slight change in the DataSet designer, it regenerates the .cs file reverting my change back to the <i>Element</i> setting.
Any idea about how to overcome this problem?

How often do you change the schema? If your in development and that's why the schema is changing frequently why worry about hiding the column? Just wait until you are finished and then change the class.

I'm looking for a free obfuscator tool.
I tried Aspose and Skater Lite, but each one of them throws an exception while processing my assembly.
My assembly doesn't contain reflection.
Do you know any other free (or light versions) of obfuscators (especialy for .NET Compact Framework 1.0) ?
My english is not so good. Please, correct my errors.
Best regards, Alexey.

Can you point me to any tool that could generate a database model (DDL would be great) from a reverse engineered model from C# classes (which are the DTOs) ? Or maybe a combination of tools?

I have a VB.net 2005 solution called MySolution.sln, with a windows project, a windows service, a class libriary, a merge module project and a windows setup project. wen i run the building command in command prompt,
devenv.exe /build release MySolution.sln
nothing is happening and no messages are returned or anything, the prompt simply goes to the next line and prompts for a new command. Has anyone ever encountered this problem, how is it solved?
thanks for looking at least.

hi there,
i encountered a strange behaviour of my wpf runtime.
every wpf program is displayed wrong, nothis is displayed correctly.
wheter it is kaxaml, vs2008 or any other wpf program i´ve written before.
i tried to reinstall .net 3.5 but the problem just remains.
i don't wanna install everything from scratch.
any ideas?
system: win xp sp2 german with vs2005pro(german), vs2008pro(english)
.net 2.0,3.0,3.5
i´ve no idea what´s going on.
any ideas? 
best regards
jk

We now have a forum on CP for WPF. This is probably a better place to ask this. Also, please try to give a more meaningful problem description that nothing is displayed correctly. You need to identify what exactly is displayed incorrectly.

well,i thought as wpf is part of the .netframework and i don't think it hasn't anything to do with wpf coding itself, the .net framework forum would be a beter place.
well, e.g. the wpf propertygrid in vs2008 is completely disrupted (as kaxaml and wpfpad also).
vs2008 is not able to display lineargradients anymore (only the last gradientstop color gets displayed), and much more.
it seems like the wpf runtime got set back to a pre-pre-pre-alpha version. (though i know the latest 3.5 framework is installed.)

Hi everybody
I'm making a web custom control which is just for getting feedbacks from visitors so I have created a database and a dataset via SQRExpress and then in my send buttom click event I have this code:
void _send_Click(object sender, EventArgs e)
{
FeedBackDBDataSetTableAdapters.FDTableTableAdapter ta=new FDTableTableAdapter();
tableAdapter.InsertQuery(Category, textBox1.text); tableAdapter.Dispose();
}
The problem is here that after I run a project which contains this control and press the send buttom, this Error Appears:  
A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)
Does any one know why?
thanks.

I think that I found the answer to this problem,(of course if any one knows a better way it's very kind of him/her to post it to me). so my answer to me is this: 
probably when you want a SQLEXPRESS database to be included in a web custom control, and then drag the control to a web page the page can not log to database for any insertion or update. I made a SQl database some were out side the control and passed the connection string to a dataset in the control and I was very pleased to see it worked!!.

i'm new in vb.net, i'm using Microsoft Visual Studio .Net 2003
i try to create a system to record customer problem regarding our system, when they call us. each time i submit the record, it will save the data that i've key-in and must generate a unique document number for our reference. i try to create the docNo but it didnt work. how to add data from 3 textbox in one field into my table? HELP..

The description "didn't work" is a rather useless. What did you do to try to create the docNo, and what happened specifically when you tried this?
Are you using a database? In that case the easiest way to create a unique id is to set up an automaitcally incremented field in the table. How that is done depends on what brand of database you are using.
Experience is the sum of all the mistakes you have done.

You could start by asking in the right forum?! I'm not aware of an easy solution - you'd probably have to set up a trigger against your database table and have that call a piece of CLR code that reset the cache in the application...
A better way would be to reconsider how you're using your cache - if the data is invalidated before the cache expires then your policy is almost certainly wrong.
It definitely isn't definatley

And what is wrong with this forum for the question? The question seemed to be a general .net related inquiry.
Have a look at SqlDependency
