Help! I using some classes that came from a program that worked...it was an example from a book. My problem is when linking my program with these classes. It dos not reconize the windows form Panel which is used for drawing. My error message is Error 1 'WingSoft.DesignWing.PlotPanel' is inaccessible due to its protection level This puzzles me becouse it is squacking about is a form component. Here is a piece of code:
public void Transform(Matrix3 m, DesignWing form1, ChartStyle cs)
{
// Normalize the point:
float x1 = (X - cs.XMin) / (cs.XMax-cs.XMin) - 0.5f;
float y1 = (Y - cs.YMin) / (cs.YMax - cs.YMin) - 0.5f;
float z1 = (Z - cs.ZMin) / (cs.ZMax - cs.ZMin) - 0.5f;
// Perform transformation on the point using matrix m:
float[] result = m.VectorMultiply(new float[4] { x1, y1, z1, W });
X = result[0];
Y = result[1];
// Coordinate transformation from World to Device system:
float xShift = 1.05f;
float xScale = 1;
float yShift = 1.05f;
float yScale = 0.9f;
if (cs.Title == "No Title")
{
yShift = 0.95f;
yScale = 1;
}
if (cs.IsColorBar)
{
xShift = 0.95f;
xScale = 0.9f;
}
X = (xShift + xScale * X) * form1.PlotPanel.Width / 2;
Y = (yShift - yScale * Y) * form1.PlotPanel.Height / 2;
} ^it does not like this:'(
}
}
I renamed the form earlier ...would i be causing my own problems since vs 2005
said it could not rename all the files?

You have another namespace which has a Panel class in it. You therefore need to specify which panel class you're using. The easy way to do this, if your code never creates the other panel class is a using statement that renames it locally, as in
using WingSoft.DesignWing.Panel as DodgyPanel;
Or something like that.
However, the fact that your error message is about a class called PlotPanel, makes me think the error has to do with how you're using an external library, and not a name clash.

Why are you accessing the control outside of the form class ?

Hello. I have a form application in C# and i wanna create an html file at run time. In Net Framework there is the HtmlTextWriter class that can do this job, but this class is for ADO applications, that is not my case. Any ideas what can i do in my case?
Thanks in advance.

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
