Both will throw an exception when you do an Add() with the same key. You can change the value paired with a key with the indexer though.

You have to write your own in order to have duplicates and there are a lot of valid reasons to have duplicates. A possible solution is to associate the key with a list or hash and inside the list have the objects with duplicate keys.

MSDE is the "lite" version of SQL 2000 and SQL Express is the "lite" version for SQL 2005. Either is good, but I would personally go with SQL 2005 Express, it is newer and there is a message a few days back stating that Microsoft does not support MSDE with Windows Vista. Microsoft does not support MSDE with Windows Vista[^]

I have an existing C# application, I have to globalize it, and make localization available for german /french and UK english.
I have not done this before, and I would appreciate, if some one can guide me to any tutorials, links, books, which can help me do this.
Thanks,

I have not had to do this yet either, but I have found Matthew MacDonald's book, "User Interfaces in C#" from Apress books extremely helpful, and it appears he has a "cookbook" approach to this in one of his chapters.
I am going to have to do this as well in a little while. I'd like to hear from you on how your experience goes.

In case you're using Visual Studio it's pretty simple. Design your form as usual with the wanted default language. If your finished, select your form and go to the properties editor. Apply true to the Localizable property and for every additional language apply the according region code to the Language property and translate all UI controls. You find more detailed information on MSDN. Just search for Globalization or Localization.
At the end some advertisment: If you're interested in allowing the user to change the language at runtime take a look at my article covering this topic here on CP: UICultureChanger component[^]

Easiest way is to put it as the first column, the subitems can't be edited I seem to remember.
Mehmet Fatih Akbulut wrote: but in price field, they should only type characters from 0 to 9
There should be an AfterLabelEdit event, you can use this to check the characters entered.

I think you can set HeaderStyle to NonClickable to accomplish this.

Hi guys,
I am getting this message when I try to run my custom tool to generate code for my crystal report. I just migrated from VS2003 to 2005. Please help, I am clueless on this.
Thanks

Is that possible in C#, to search for objects of a certain type that are currently alive (in memory).

If you mean .NET objects then...
You can use the System.Diagnostics namespace to get process information. From there you can get the paths of any executables or dlls etc, you can load these using the System.Reflection namespace and then scan through the assemblies using Reflection for the objects you want. You probably can't get a copy of the objects currently in memory as Windows and the framework will disallow this (although there might be a way).

Hi;
Thanks for your answer.
I did study this possibility but I could'nt find a way to get references to .NET Objects.
By Reflection all I can have is the structure of the loded modules but I can't actually see which calsses have been instanciated , how many times and what are the references to these instances.
I know it is possible though because CLR Profiler can generate a snapshot graph of managed memory with the reference and memory adresses of each .NET object.

kASTRATOR wrote: CLR Profiler
Yes but is that using Managed or Unmanaged code. If it's C++ with some C++/CLI involved then it might be able to since it can inject itself into processes.
I havn't tried any of this, just giving you my thoughts. I havn't even used the CLR Profiler.
If the profiler is managed (which I doubt) then you can take a look through it's code with Reflector.
Did you know that you can get the source code to the profiler. Just google for CRL Profiler and the first result will be for .NET 1.1. A few results later (~5) there is a blog which contains a link to one for .NET 2.0.
Maybe this will help you if you look through the source code.

As you advised; I just took a look to see how CLR Profiler manage scanning memory.
It seems he's using a C++ unmanaged library that goes with pointers arithmetics.
I would like to avoid going through pointers; I'd rather find a solution to do it in C#.

To be honest I don't think that you'll be able to avoid using pointers, the only way would be to use a wrapper around some stuff that did use pointers

I'll try to implement an algo similar to GarbageCollector one. With root references and scanning through the tree structure of each root. It won't be as generic as I wanted to. But going through pointers woul be very expensive in time for me.

Hello,
I am developing a web app and trying to use Enterprise Library 2.0. I am using it for logging for now. I achived the logging on a flat file but when I tried to start doing the logging by using a DataBase Listener. I failed.
Here's how I am using it after including all possible references to my web app.
I configured a datasource with following attributes setup:
-Server (my server name)
-Database (my database in my server)
-Integrated Security (I used API.. something, false, true and I even tested after removing this tag aswell).
-user (my user name)
-pwd (my password)
Then I configured a Database Listner and gave the reference of my datasource.
Then I configured a Logging block by adding different categories and then I added reference to my Database listner in categories.
I also tested by adding and removing following in web.config within CodeDom tag:
type="Microsoft.CSharp.CSharpCodeProvider,
System, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089"
compilerOptions="/d:TRACE" />
----------------
After doing this all when I try to log an entry after specifing the category to the entry and other required attributes. NOTHING HAPPENS in tables I generated after running the script file provided by Best Patterns and Practices team. I couldnt log any data.
Is there anybody who can help me or tell me what I am doing wrong?

There are articles all over the web on how to do this. Just fire up Google or Search through the articles on this site.

It depends on your requirements, some times they can be interchanged, some times they cant.
