I'd rather use the MouseDown event and check e.Clicks = 2. It allows you do find out which button (DoubleClick is fired indistintly for left or right buttons.)

But the rest, stays the same.

Nunit for TDD or testing

Hi, I have a question, should we use Nunit for testing and at the same time avoid the TDD part, since TDD can be time consuming for short term projects.

Please your comments will be appreciated.

Hey I have this regex expression

"([\w\s]+)* ([\w\s]+)* West" <== 2 white spaces after *'s

that for some reason, when matched against the string

"Day Amount Direction3 100 West5 43 North5 44 North West7 54 South2 5995 East2 5995 North,Northwest 54 35345 543 North6 West"

Makes 3 regex engines i've tried (java and expresso, .net) crash or something. They just sit there and consume 100% processor time...

Does anybody know what's going on and how I can match this expression?

/\ |_ E X E GG

What part of the string do you want to match?

"Expresso" crashes as well.

Any character any number of repetitions a space any character any number of repetitions a space and "West"

That's what I want to match. It should get 2-4 matches depending on variables...

Is this ok? It would match:

Hi everybody i got a problem in DLL and COM interoperability so could some one help me please !!!
I want to create a COM object in C# called conversion.dll
So I begin by creating Class Library project called “conversion.dll”
1-I add reference to a COM Object called “devise.dll”
2-When i compile the project a wrapper is created by VS.NET called “Interop.devise.dll”
3-i compile in VS.NET no problem and that’s great!!!
3-but to create the COM object conversion as I know i must add a key file called “conversion.snk”
So to create the file I go to prompt
Sn –k conversion.dll
5-i edit the file AssemblyInfo.cs in my project by adding
[assembly: AssemblyKeyFile("conversion.snk")]
6-I compile boooooom !! an error was generated
Message the assembly Interop.devise referenced is not a strong name !!!!!!
So how can I process to create the COM object conversion.dll knowing that the COM object devise.dll is alredy existing in the client Side..
Thank you in advance!!!!

You no need to add key file unless it is to be put in Global Assembly Cache. In the command prompt you just move to your project folder and then to bin\debug. Type the following in the command prompt

>regasm <yourcom>.dll /tlb:<tlbfilename.tlb> /codebase

Here the /codebase switch is important. It will set the code base in the registry.

Now, you will be able to access the component in com client.

You have escaped your "end of string" marker. Take out the "\" before the $ and it should match.

one another thing this pattern will match somthing like
80:90:95 because you din't specify the range
for valid hour,minuts,seconds

Here you go

^(?<Hour>[0-1]\d|[2][0-3])(?: Smile | :)

(?<Minutes>[0-5]\d)(?: Smile | :)

(?<Seconds>[0-5]\d)

Puts it into nice groups of Hour Minutes and Seconds. If it doesn't match it is not valid. It is based on a 24 hour clock.

23:59:59 valid but
24:00:00 is not

Thank you

The DataGridColumnStyle has an "Alignment" property that you can set to HorizontalAlignment.Center.

I can't find it. I have:

this.styleStages.GridColumnStyles["ColumnName"]

ColumnName has allignment property, but that will allign the data inside the cells, and not the header. Am I looking in the wrong place?

Thank you

Humm, that's interesting. I guess setting the alignment after adding a TableStyle then only sets alignment of the data.
Anyway, when I tested on my datagrid I did the testing during the creation of the TableStyle.
Example:

<br />
private void CreateGrid()<br />
{<br />
DataGridTableStyle ts = new DataGridTableStyle();<br />
ts.MappingName = "TableName";<br />
<br />
DataGridTextBoxColumn textCol = new DataGridTextBoxColumn();<br />
textCol.MappingName = "ColumnName";<br />
textCol.HeaderText = "Test Column";<br />
textCol.Alignment = HorizontalAlignment.Center;  <<-- Set alignment here<br />
ts.GridColumnStyles.Add(textCol);<br />
<br />
myGrid.TableStyles.Add(ts);<br />
}<br />

XML Question

I've got a set of xml files which all look similar to this one:
<?xml version="1.0" encoding="utf-8" ?>
<designs>
<item>
<title>Standard</title>
<description>Das Standard Layout.</description>
<stylesheetname>default.css</stylesheetname>
<imageurl>standard.jpg</imageurl>
</item>
<item>
<title>Text Version</title>
<description>Das Leichtgewicht.</description>
<stylesheetname>textonly.css</stylesheetname>
<imageurl>textonly.jpg</imageurl>
</item>
</designs>

The number of item elements varies. What is the easiest way to loop through the xml and extract the individual data items? I had a look at the XmlTextReader but the methods provided in this class seem a bit cumbersum. There must be an easier way...

Any help is greatly appreciated.
