You could use the Application.StartupPath.
OleDbConnection Connection1 = new OleDbConnection ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ Application.StartupPath +"\\SC226_db.mdb");

Try string strCurrentDirectory=Directory.GetCurrentDirectory();
This will return current directory of ur application ie. bin directory.Put ur database(.MDB) file in this directory.

Not necessarily, that current directory can be changed.

Hello,
It's System.Enviroment.CurrentDirectory
All the best,

Good practice is to ALWAYS use fully qualified path names when accessing files, even in connection strings. You cannot guarantee that the "current directory" will stay that way, so...
string databasePath = Path.Combine(Application.StartupPath, @"SC226_db.mdb");
string connString = String.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0}", databasePath);

Whats the best most efficient way of checking whether a resource (image, page, document etc.) exists at a particular URL web address location. Eg. I have a url http://www.example.com/myImage.jpg and I want to check whether myImage.jpg actually exists.
At the moment I'm using the WebClient class like so...
WebClient client = new WebClient();<br />
<br />
try<br />
{<br />
if(client.Download("http://www.example.com/myImage.jpg").Length > 0)<br />
{<br />
}<br />
else<br />
{<br />
}<br />
}<br />
catch<br />
{<br />
}
...problem with this method though is that it downloads the entire file to check it's existence. I'm not interested in the file, just whether the server will return a 404 or not.
Cheers!

Include System.IO and System.Text namespace to your project
Then you would be able to access File class which has a method defined for checking the existence of files as shown below
if (File.Exists(@"//localhost/command.gif") == false)
{
Response.Redirect("FileNotFound.htm");
}
else
{
Response.Write("File Exists");
}
I tested this code on my localhost, it works fine. I think this code would access the client machines path for the file and not the server's, just verify and let me know.

Just tested it with IronPython:
>>> ex = File.Exists("http://www.codeproject.com/script/images/news_answer.gif")
>>> ex
False

Your question is very vague..why do you need to write the code to check for file existence on some other web server ? Its a built in thing, if u request for a non-existent page, the logic on that server will automatically handle the request and show you an error page. However, if u wanna do this for your own server you can, using the below given code.
if (File.Exists(Server.MapPath("web.gif")))
{
Response.Write("File Exists");
}
else
{
Response.Redirect("FileNotFound.htm");
}
This code will map the virtual path of your server so if some client browser requests for a file that does not exist on your web server, he will get an error page other wise the page will load, now it depends on you how you customize the application for your clients.

Long story but we have a list of external URLs which point to images on another web server, which we need to display on our site via an img tag or asp:Image control. Thing is some of these URLS are incorrect and point to images that don't exist, and rather than display an empty image box with a red X, they want a replacement image instead. Basically, they want us to guard against their own bad data. I know it's additional overhead but it's what they want, I think I can optimise it by caching the state of the external image for a time. But File.Exists("http://www.example.com/image123.jpg"); should do the trick.
If you know of a more efficient way let me know. Cheers!

This Regex will work fine, if your strings won't contain any < and >-signs:
<([^<>]+)>

Thanks for reply Greeeg !
But the regular expression is not completely correct!
I just want the info within <> and nothing else but the
regular expression u had given is showing the rest info also.
Do u have any idea to extract all values within <>
?????

That's what the paratheses are for. It's called a "group". You can usually access the first group with matches.Group[1].Value

When i just change the location of a form with an overridden show-methode and theange of the size form is hidden while i change the location, the size will be changed too 
like
public void Show( IWin32Window owner, int positionX, int positionY ) {
if( this.Visible == false ) {
this.SetDesktopLocation( positionX, positionY );
this.Size = this.RestoreBounds.Size;
this.BringToFront();
this.Show( owner );
}
else {
this.Activate();
}
}

Windows XP Pro and Windows Server 2003 both have the option to install an FTP server when installing IIS.
Start Menu >> Control Panel >> Add or Remove Programs >> Add/Remove Windows Components

There are a lot of free hosters on the net, and also there are many FTP Servers freeware that you can install on your workstation.
An example, a excellent freeware FTP Server is CesarFTP.
Besides, try to search "free hosting services" on the net, almost all of those provide FTP access.

i want to make T9 dictionary in c#.how to start?????????
|
|

|

I would guess that you would need to have a dictionary made up of words and their associated numeric values. Then, you would scan the numeric values to see what words matched. Beyond this, you could use it to predict words by pulling all the words that start with the predictive value based on the key sequence so far.
Beyond this, of course, you will need a dictionary of words. I've given you an indication of what you would need to do code wise - it's up to you to get the dictionary.
