You can create a project class library project which holds such classes. Provide the reference of this project in all layers.
Sorry, the arrow shows the flow of the data objects not the reference.
Reference would be as follows
Data Access Layer - Ref of common
Business Layer - Ref of Data Access Layer and Ref of Common
UI - Ref of Business Layer & ref of Common

This sounds like a serious case of entanglement. Why should Point know about MyDatabase and why should MyDatabase know about Point? What you might want to look at instead, is using interfaces to control the way things interact, and then code against the interface.

Using VB.net...
I've got an owner drawn toolstrip combobox that displays my system fonts. Each item in the drop down list is in its respective font. Works okay, but the top of the combo where the selection is displayed also uses whatever font is selected. How do I get the combobox to use its default font at the top and still have the drop down list display multiple fonts?
Also, the "Cambria Math" font in Vista displays as being about three lines tall, with tiny text in the middle of the line. That's in my text editor, OO.org and MS Works. A friend tried it in Word and it just produced onscreen gibberish. Anyone else encounter this with Cambria Math?

I'm on a project with several components (projects) which are deployed on multiple servers. Several components have their own web.config or app.config files with logging configuration settings, all flat file loggers. Some have config files with no logging configuration. Since all the trace listeners point to the same file, everything manages to get to the destination. This will change. I need to understand how the ELLB deals with multiple configuration files.

Does it? I thought each application supplies it's own configuration?

Sorry for my lack of clarity.
There are several projects withing this solution. Many of them provide their own app.config or web.config files. At the moment, each of the categories in all of configuration files ultimately point to the same flat file, trace.log. So all the entries are written to the same file, at least the same file on a particular server. As requirements are changing, different projects need to point to files named something other than trace.log. There will be multiple log files in use. Also, there will be situations where different projects will still need to write to the same log file. Right now, that means managing multiple configuration files, which I would like to avoid if possible.
There are also projects in the solution which make calls to logger.write, but have no config file defined within that project. All the projects have a reference to what I assume are the same binaries for the Application Logging Block (we are not extending that code in any way). The logging in these projects appears to be working, so my assumption is that they are finding the categories defined in some other project and making to the log file. This may be an incorrect assumption on my part.
I guess what I am really looking for is a way to manage the logging across multiple projects (assemblies) within the same solution using as few configuration files as possible, ideally one. This may not be possible. But I have not yet found any documentation that discusses this situation.

I’m not an expert on the logging block but it wouldn’t seem likely that any sort of organization like you describe is part of it. There would be far too many variables to account for in a generalized library. If you want some sort of central management of logging configuration across your suite of applications you will probably have to develop that yourself.
I don’t have your complete requirements (and I don’t want them), however one thing you might consider is that a build system could potentially allow you to develop a centralized configuration that will automate the distribution of information into the project files. I’m pretty sure you could use ANT to accomplish that so I imagine MS Build might work as well.

How do I go about using filtering on the built in trace listeners, such as System.Diagnostics.DefaultTraceListener and System.Diagnostics.TextWriterTraceListener?
I don't want to have to override write methods and explicitly check the filtering, but I can find no way to attach a level to trace information?

I'm trying to save a unicode utf8 string --> "سلام" in a feature of a featureclass, but it is saved like "????".as ArcMap support different encodin and also Farsi that I'm working with, It should be possible through my program.but I didn't find any way yet.anybody knows about this?
<br />
<br />
feature = fc.CreateFeature();<br />
feature.Shape = point;<br />
feature.set_Value(feature.Fields.FindField("Name"), o.Name);<br />
feature.Store();<br />
fc is an IFeatureClass, feature is an IFeature and o.Name is a unicode.utf8 string.in watch window:
feature.get_value(feature.Fields.FindField("Name"))--> is OK
but
fc.GetFeature(1).Get_Value(feature.Fields.FindField("Name")) --> is "????"
and this is what is saved. What should I do?

This code will export the datalist into Excel with exact text,position and style in asp.net.
Please include System.IO at the top of the file.
string filename = "BacklogData.xls";
Response.Cache.SetExpires(DateTime.Now.AddSeconds(1));
Response.ContentType = "application/vnd.ms-excel";
Response.ContentEncoding = Encoding.Unicode;
Response.BinaryWrite(Encoding.Unicode.GetPreamble());
Response.Charset = "";
this.EnableViewState = false;
Response.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");
Response.Write("\r\n");
Response.Write("<style> .text " + "\r\n" + " {mso-style-parent:style0;mso-number-format:\""+@"\@"+"\""+";} " + "\r\n" + "</style>");
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
DataList.RenderControl(hw);

Hello there!
My code is highlighted below.I have five tabpages(two is shown here!) on a form called vwpatient that runs each time a tabpage is selected.The code below works but my problem is this: there is a textbox called sachPatient.patID from another form called sachPatient, the code pulls data from the database on clicking one or two pages, but if more than two is clicked, an exception fires saying "Make sure you have not released a resource before attempting to use it". I have tried endlessly to fix this problem to no avail. And am still trying!!.
I would appreciate if someone can help me.
Thanks in advance!!!

First of all, you can replace the loop through the TabPages at the start with a simple TabControl1.SelectedTab.Name and do a Select Case on that. Second, please post your code in <pre> tags. Lastly, which line does the error occur on?

Hi,
if
(1) you watch all the exception information using Exception.ToString()
(2) you told your IDE to always show line numbers in edit windows
then it is easy to figure out which line causes the problem.

depends on the IDE.
On some versions of Visual Studio, it is under menu Tools/Options/TextEditor/AllLanguages: display line numbers.

I'm not making such comment, I try to make you help yourself in the first place. Code quality comes with dedication and experience.

Somewhere in this mess you've released a resource (i.e. Disposed of it) - my guess would be that it's the connection that's causing you problems.
