Ha! Such a simple solution. Thanks, that's exactly what I wanted and I feel rather silly not to have known it.

The Nullable stuff applies to value types; reference types are always nullable, as a reference can be null, you don't need anything new for this.
Your compiler error message told you "use of unassigned local variable", which is correct as "myInstance" in your second snippet did not have a value assigned, not even null. (in C# class members have a default value, local members don't).
myClass myInstance=null;
...
if (myInstance == null) ...

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that. [The QA section does it automatically now, I hope we soon get it on regular forums as well]

Hi, I need to strip out text from a big file and my condition is:
I need to strip out text from below
<pre>
<div class="a">apple</div>
<p>&nbsp;&nbsp;</p>
<p>red delicious</p>
<div class="b">banana</div>
<p>&nbsp;&nbsp;</p>
<p>riped banana</p>

<p>&nbsp;&nbsp;</p>
<p>fresh green chives</p>
</pre>
to below
'apple', 'red delicious'
'banana', 'riped banana'
'chives', 'fresh green chives'

you can edit (i.e. modify) an earlier message if you decide you need to fix an error, improve formatting, or add information.
Now please go and delete your other messages before someone attempts to read and answer them.

At the very least, you could use Linq-to-XML to do this. Don't use Regex to parse HTML.
The class you're going to want to look at is XElement.

It doesn't have to be a xml/html file. It just needs to be a properly formatted XML string. Trust me - regex is not the answer.

| formatting takes ages. my element doesnt have a id. why would you come to the conclusion regex is not an answer? when i know all the text is going to be in same format?

I've been playing with this library (.NET 3.5 SP1 version) and trying a few snippets from various blog posts. I've also asked in the MSDN Rx forum.
This works fine
var observable = Observable.Empty<int>()
.StartWith(1)
.StartWith(2)
.StartWith(3);
observable.Subscribe(Console.WriteLine);
These produce no output
var enumerable = Enumerable.Range(1, 10);
var observable = enumerable.ToObservable();
observable.Subscribe(Console.WriteLine);
var observable = Observable.Generate(
1,
value => value <= 10,
value => value,
value => value + 1);
observable.Subscribe(Console.WriteLine);
What am I missing?

Hi,
I need my installation project to work in a specific way. there are some folders containing files. I don't always want to install all the folders. Also I don't want to build the setup everytime, so is there a way i can use ini file or xml file to customize my setup installation. I should be able to configure the folder names and only those specific configured folders should be installed.
Thanks.

Any time you want to exceed the capabilities of the built-in setup builder, you should consider using an external utility, such as Inno Setup.

hi all.
i want to add items and sub items to menu strip dynamically
how can i do that??
thanks all;

if you can do it with Visual Designer, you can do it with code as well. Have a look at what designer puts into its Xyz.Designer.cs file; and/or read the MSDN documentation.

Hello Guys,
At work I am developing a new reporting system where this small application will generate the report from an XML file and then gather the data from a database and the process the report in WORD Format. Now after i developed this application and tested it on my development machine it worked compleetly fine. But when i put it into production it was always giving me the same error "Object not set to an instance of an object". After investigating more i found out that it was crashing when it was trying to query how many boookmars there are in the word document, I found out that the Document was not being opend.
This is my code below:
Microsoft.Office.Interop.Word.ApplicationClass WordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
object filename = System.Configuration.ConfigurationSettings.AppSettings["ReportPath"].ToString() + @"\template\" + TemplateNode.Attributes["path"].Value;
object _readonly = false;
object isVisable = true;
object missing = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Word.Document WordDocument = WordApp.Documents.Add(ref filename, ref missing, ref missing, ref missing);
This code is resulting in the Object "WordDocument" being null. Now the funny thing is that this works fine in my developemtn machinie but id dosent work correctly on the server.
My Development Machine = Windows XP
Server = Windows server 2003
Anonye has any ideas as i am lost?
Regards,
Christian Pace

wrong file path?
access restrictions?
wrong Office version?
a code bug?
you need to open your eyes and debug the situation.

I did the file path is correct, there are no restrictions and the office version is correct i am using the same installation on both the development machine and the server so the word version is the same. and how can it be a code bug when i went trough it on the development machine and it worked fine.
