Hey guys,
I have a question regarding the components which have a built in datasourse, like datagrid, combo box, ...
I dunno whether my windows application I'm working on, is gonna be run on a single computer or on a server and in a network, so how should I define the connection string, clearly I cannot go for code-less method (am I right ? ), so how should I tackle this problem ?
this is basically my general question for my whole application as well and Would be greatful if u helped me out!
regrads,
K

Never hard-code connection strings - put them in the application config file. That way the DB can move without code changes.

I'm aware of that, and thats what I'm doing but still the servername differs from one computer to another, well one solution I thought of was to install their SQL server manually set the server name to a specific name which is in my application ... but I wanted to see if there were other possible ways !
regards

Include the servername in the connection string - it is part of it. Then configure SQL server as part of the install procedure (do a test connect and if it fails get them to enter it manually) then save it in the app.config file.

I prefer to have a system-wide, non-application-specific configuration file that lists the databases available to the system.
Such a file can be stored in the Application Data directory for the user or all users -- so all users can have the same settings, or each user can have his own.
And I don't store actual connection strings; I store the information required to cobble one up for the requested database engine.
Here's an older version:
<DATABASES>
<CT TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="CoconutTelegraph" />
<DTER TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="DTER" />
<DDLTEST TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="DDLTEST" />
<FIREBIRD TYPE="FIREBIRD" SERVER="LOCALHOST" NAME="C:\Program Files\Firebird\examples\empbuild\employee.fdb" USERNAME="SYSDBA" PASSWORD="masterkey" />
<MPG TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="MPG" />
<MR TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="MusicLibrary" />
<RUBBISH TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="Rubbish" />
<SA TYPE="SQLSERVER" SERVER="LOCALHOST\SQLEXPRESS" NAME="VersionControl" />
<WORDSEARCH TYPE="ACCESS" NAME="C:\projects\wordsearch\bin\release\WordSearch.MDB" PASSWORD=":badger:" USERNAME="admin" USERPASSWORD="" />
</DATABASES>
And here's a version I'm working with this week:
<Databases>
<Junk Provider="SqlServer" Parameters=".\SQLEXPRESS,Junk" />
</Databases>
This allows the application to be more database agnostic -- it doesn't need to know which database engine is in use.

After read the Essential C#, I am still puzzled why C# has the event keyword.
The Delegate is similiar with the function pointer in C/C++ and can make the function of programming needed. So I think that the event is unwanted.
right?

Wrong. Sorry, but event is a specialist form of multicast delegate - to achieve this specialism, the event keyword was necessary.

You're wrong, and that's probably why you're not working on the C# team at Microsoft.

Yes, but... the event keyword allows special handling of the multicast delegate:
0) Only the defining class can raise/call/execute the event.
1) All other classes are required to use the += and -= operators.
You are welcome to use non-event multicast delegates in your code if you like. Come back and let us know how it goes.

Your answer is good. I know event is useful,
Thanks very much.

I am working with .net application. I have few informations in string. Now i would like to put this string into html tags. Lets say i have array of names and i would like to write them down in html paragraph. How could i do this in c# code?
|
|

|

You can use response.write() function to do that.
string htmltodisp="here is my string to display in paragraph";
Response.Write("<p>" + htmltodisp + "</p>");
Hope this will help!

It depends how you want to format the data. Suppose for instance that you want each name in a paragraph, a quick and dirty hack to do this would be to use something like:
StringBuilder sb = new StringBuilder();
foreach(string name in names)
{
sb.AppendFormat("<p>{0}</p>", name);
}Alternatively you could look at the HtmlTextWriter[^] class to do the job properly.

I think he's better off writing it the frist way. What benefit does the HtmlTextWriter have? I diodn't see any, myself.

I wasn't sure if he was working in an ASP.NET environment. If he is, and he's developing a custom control (again - unsure, so I've gone for the safe case here) then the HtmlTextWriter (and children such as the XhtmlTextWriter) are a good fit.

I would use WebUtility.HtmlEncode from System.NET library.
It provides a correct encoding of '<','>' and '&' ,...
Your html code would have bugs, if your string contains one of the chars and you don't encode them.
You can decorate the converted string with html tags.

Hey Guys
I'm using the RegEx to do some pattern matching, but I'm after finding one of 2 specific strings.
At the moment I'm using Regex reg1 = new Regex("FIRST[ ]+STRING");Regex reg2 = new Regex("SECOND[ ]+STRING");
Is there a way I could get the Regular Expression to say match exact string A OR exact string B in the same statement? (eg Regex exp = new Regex("ThisString or ThisString");
Thank you in advance 
oooo, the Jedi's will feel this one....

Regex exp = new Regex("(ThisString)|(ThatString)");
Will do it nicely.

Thats it??? 
So simple. I'm kicking myself now. Thank you.

You're welcome - technically you don't need the brackets, but I always feel they help to make it more readable (if a regex can be described as readable... )

Before I forget - have a look at Expresso[^] - it examines, creates and explains regular expressions. It works, it helps you understand how they work, and it's free.
