I'm not getting why you think you can't use the class that was created for the purpose.
You can just use a basic textstream if you want, too. Or a string builder.

If I have the URL of a file e.g. http://mysite.com/file.php?f=1 where I cannot see the extension of the file is it possible to determine the mime-type of the file without downloading it first?

You can download first several bytes and use Magic Numbers to detect type

But then I would need a lookup table, don't I? Is there no way this could be done with the .net framework? There are applications which have exactly this kind of functionality for example if you click on a download link with most browsers they display the mime-type without downloading. How is it done there?

Hi,
normally a HTTP request performs a GET to receive the entire page.
however you can also do a HEAD which requests just the head information, which
often includes the mime-type, whereas the body is not transfered at all.
I once did HTTP with the Socket class; I trust you can do it with HttpRequest too.

I am looking for a regular expression. I have the following text
[MyTag]
[/MyTag]
[MyTag]
[/MyTag] I need to match the text written inside the tags. My expected match is
I have the following expression with me which matches the content between tags.
\[MyTag]([\w\W]*)\[/MyTag] This expression works, but I am getting the matched text as
[/MyTag]
[MyTag]
It's only considering the outer tags. Can anyone help to correct this expression ?
|
|
|
|
|
The asterisk is being "greedy"; try *?
From the help:
"
*? Specifies the first match that consumes as few repeats as possible (equivalent to lazy *).

Hello.
I have a text file that looks like this:
0 1 "Bull Fighter" 6 100 0 16 20 6 0 28 6 3 0 1 5 400 1600 10 2 130 10 6 0 0 0 0 0<br />
1 1 "Hound" 9 140 0 22 27 9 0 39 9 3 0 1 5 400 1600 10 2 130 10 6 0 0 0 0 0<br />
2 1 "Budge Dragon" 4 60 0 10 13 3 0 18 3 3 0 1 4 400 2000 10 2 120 10 6 0 0 0 0 0
It is called monster.txt
The first value is a id which I also use in my script.
Lets say I have the id 3, this would be "Spider" since the first number of "Spider" is 3
What is the best way to read the monster.txt file for the id and retrive the name? (Name = "Spider", id = 3) (As my example above)

Split() will work but you have space in name too, i will suggest you to convert your line like this, if possible :
0~1~"Bull Fighter"~6~100~0~16~20~6~0~28~6~3~0~1~5~400~1600~10~2~130~10~6~0~0~0~0~0
then you can use Split('~')
hope this will help

Its not a problem getting the monster name. When I just have the line, it is no problem.
The problem is reading the file and accessing the line through a id.
Because it would be pretty silly to read the whole file just for 1 line.
|

|
|
Casper Hansen,
You cannot read only 1 line of a text file. You need to get the whole file, and then search for your ID.
Regards,
Gareth.

As presented you have to read the entire file.
Or use an index in a separate file.
Or alter the format somehow. For instance each line could begin with the length of the line.
Personally, I suggest using XML, but that's just me.

|
|
|

read all lines from text then do your operation, to read all line here is the shortest ways :
string[] lines = File.ReadAllLines( <FILEPATH> );
hope this will help

That's why Split should have the ability to honor quote characters... as mine does.

Depending on how often you need to access this information you'd probably be better off storing this information in a DataTable (which you could create at runtime). You can then use the Rows property of the DataTable object to retrieve your row at the given index.
I also agree with the previous poster that you should use a different char for separating values.

I just used
private void findMonster(int monsterId)<br />
{<br />
StreamReader sr = new StreamReader(@monsterLocation);<br />
int searchId = monsterId;<br />
int actualId = 0;<br />
string name = "(Not found)";<br />
string[] details = null;<br />
string line = null;<br />
while ((line = sr.ReadLine()) != null)<br />
{<br />
line = line.Trim();<br />
if (line == "") continue;<br />
details = line.Split('\t');<br />
actualId = int.Parse(details[0]);<br />
if (actualId == searchId)<br />
{<br />
name = details[2].Replace("\"", "");<br />
break;<br />
}<br />
}<br />
sr.Close();<br />
txtMonster.Text = name;<br />
}
Dont know if its the best way, but it works..
As you guys said I should use some other database form then txt, but the game im devolping this software to is using txt files so cant rellay change it 
|

|

XML is text. CSV is text.
|
|
|
|
|
I said txt not text 
|
|
|
|
|
Yeah, so?
"txt" is not a reserved extension for some special format. Likewise the extension of your file could just as easily be "dat" or "casper".
I merely meant to suggest that you not use the format shown if at all possible.

Hello everyone,
Here is the description about when to use Pulse and when to use PulseAll to achieve best performance.
My question is, I do not quite understand this situation, "Sometimes, however, different threads are waiting on different conditions, but all waiting on the same monitor. In that case, you need to use PulseAll so that you make sure that the thread which is waiting for whatever condition has just occurred is able to notice it and make progress."? Could anyone show a scenario about what means "different threads are waiting on different conditions, but all waiting on the same monitor" please?
(the link and related whole paragraph is quoted below)
http://www.yoda.arachsys.com/csharp/threads/deadlocks.shtml
--------------------
The reason for having both Pulse and PulseAll is for different situations, where you're waiting on different conditions. If either there'll only be one thread waiting, or (as is the case above) any thread can consume any produced object, you can just use Pulse. If there are several threads waiting on the object, that ends up being more efficient than PulseAll - there's no point in waking up a bunch of threads if you know that only one of them is going to be able to make progress, and that it doesn't matter which you wake up. Sometimes, however, different threads are waiting on different conditions, but all waiting on the same monitor. In that case, you need to use PulseAll so that you make sure that the thread which is waiting for whatever condition has just occurred is able to notice it and make progress.
--------------------
thanks in advance,
George

Hi All,
I'm just looking into the options for including either SQLExpress or SQL CE for my local (one user) data store. Having read up on it some it seems that there are more security considerations if you include SQLExpress (and a larger download). Has anyone here deployed an app that used SQLExpress to very non-thechie users?
How much more complicated is it to embed SQLEXpress over SQLCE?
Cheers,
Jammer

make a installer that will install SQLExpress before installing your app
i think you cannot embed sql in your app

Hi,
I've basically opted for SQLCE. After reading up on the two on the MS site (there is loads of good comparison stuff there) it seems that SQLCE should to the trick, and its going to make my download a LOT smaller ... like 1.8mb for SQLCE vs 60mb for SQLExpress.
Your right, SQLExpress is not embeddable like SQLCE and makes the install process potentially a LOT more complex.
Cheers,
Jammer
