Xpath can be tricky :p Try some variations eg
/VoteData/Question[@id='0']/
/VoteData/Question[@id='0']/*
VoteData/Question[@id='0']
I cant recall the exact syntax, but something normally is just in the wrong place :p
Also, why not call SelectNodes from the VoteData xml doc itself? that mite be causing the Xpath not to match the VoteData bit.

Its tricky for me as I rarely use it, and tend to forget the exactly syntax. XPath is simply Regular Expressions for XML. The is a complete standard for it. .NET supports version 1.1 I think.
The easiest way to test things is just to start with "*" and continue up to "*/*/*" and see what is really being matched, from there is should be easy, except if you are using XmlNamespaces (which u are not). Your problem looks like a context problem, iow you are starting at the wrong node, like I mentioned in my previous post.

Why do you have the in you xml file? Check if xElement is empty
I use something like this and see if sId has some value
XmlNode node;
node = xml.FirstChild;
while (node.Name != "Ticket" & !(node == null))
{
node = node.NextSibling;
}
string sId;
sId = node.Attributes("id").Value;
|
|
|
|
|
while (node.Name != "Question" & !(node == null))
{
node = node.NextSibling;
}
|
|

the file may be large and that way may take a long time to select the node i need, do u think that XPath using this way to select nodes ? i dunno
|

|

yea thats right, but am implementing a stand alone component that don't relies on database, it has its own data file, thanks

The XPath is fine, that is not where your problem lies. I just made your XML valid and tested it.
If I have trouble with an XPath, I use XSLerator or something similar to test it, and build it one step at a time.

i think i caught where the problem lies, the problem is me, damn, sorry guys, i didn't paste the exactly code as in my project , its my first time using xml so don't blame me, i think i'm using a namespace, and heres my exactly xml file
<?xml version="1.0" encoding="utf-8"?>
<VoteData xmlns="http://tempuri.org/VoteData.xsd">
<Question id="0" name="do you believe in think tanks?">
<Choice choiceid="1" votes="7" name="Yes">
<Vote ip="192.168.1.1" />
<Vote IP="50.50.20.10" xmlns="" />
<Vote IP="50.50.20.10" xmlns="" />
</Choice>
<Choice choiceid="2" votes="1" name="No">
<Vote IP="50.50.20.10" xmlns="" />
</Choice>
</Question>
<Question id="2" name="bet7eb Sawsan?">
<Choice choiceid="0" votes="0" name="aiwa" />
<Choice choiceid="1" votes="0" name="la2" />
<Choice choiceid="2" votes="0" name="moot" />
<Choice choiceid="3" votes="0" name="ya3ney" />
</Question>
</VoteData>
i didn't think that will be a diffrent while using namespace, so now, what should i change in my C# code to let XPath work ?
sorry guys again and thanx

Hi all,
I am trying to two things but am unable to do them.
1. I am trying to dynamically add some element in the HTML page with the help of createElement function. I am able to that correctly in IE but not in Netscape 4.7 I refered the javascript reference which says that createElement is not compatible with Netscape. So what is the other way round to do it.
2. Also I am trying to make a div element fixed in the page. That is even if I scroll down the page the div element which is a type of layer does not scroll down. It is possible in IE as:
document.getElementById("divname").style.pixelTop = document.body.scrollTop;
but it is not possible in Netscape4.7 as netscape does not support scrollTop. What is the other way round to do it.
Please help.

Why in gods name are you still trying to support Nutscrape 4.x? That browser is older than the theory of evolution!
|
|
|
|
|
Due to some urgent requirenments I would make my programme compatible with Netscape 4.7 and also Firefox.
|

firefox i can understand, its recent and its reasonably well used - NN4.xx on the other hand is neither.
You will have to see if you can dig up any old NN Javascript docs, as that will guide you on how do deal with the DOM in NN. Most things are possible from a DHTML standpoint, but some just simply are not with that browser.
From memory, you can create a div layer and then write HTML into it using innerHtml property - but you can't createElement like in newer DOM's.

Your question has absolutely nothing to do with C# or even the .NET Framework and should be asked in the Web Development[^] forum. Even if this is produced from an ASP.NET application written in C#, your question is regarding client-side HTML which ASP.NET has little to do with (and nothing in this case). ASP.NET produces HTML and other content that is downloaded to the client. What happens on the client is totally up to the client, which is why your question belongs in the Web Development forum.

I am a VC 6.0 developer right now i am facing a problem of transfering my image from a dll developed in vc 6.0 to c#
at first i tried to make image from stream in c# and because a can get byte* and size of image from the vc6.0 i got my image this way but now the image was colored (although the original is in black and white) so it actually made the mess with colors of image.
right now i can access Byte* , BITMAPINFOHEADER (also all the variables in bitmapinfoheader) and i want to make system.drawing.bitmap or system.drawing.image from this byte* and assign it to picturebox in c#
please help me out as it is urgent
thanking you in advance and hope for the best results

A bitmapinfoheader contains a lot of header info ( funny enough), and also a pointer to the bytes that represent the actual image. One way to do it would be to read the header to find out the size and depth of the image, create a bitmap and copy the bits into it.

Hi all,
I intend to use the Firebird database engine as the embedded
database engine of our desktop window application written in C#.
Have anyone used it before and is it good enough ? How is it compared
to the Microsoft MSDE data engine in performance, in ease of installation, maintainability....etc.. ?
Thanks

Of any URL? And what URLs would those be? Internet Explorer isn't the only application that makes use of monikers like URLs. And are you talking about URLs of a running instance of Internet Explorer? If so, you can create an interop assembly (RCW) from shdocvw.dll and use the InternetExplorerClass to either create or access a running instance, from which you can then get the URL in a number of ways like the InternetExplorerClass.LocationURL property.

Consider the following C# code -
class TestClass
{
public string str;
}
class TestApplication
{
static void Upper1 ( string strParam )
{
strParam = strParam.ToUpper ();
}
static void Upper2( TestClass tc )
{
tc.str = (tc.str) .ToUpper ();
}
static void Main ( string[] args )
{
string s = "lower 1";
Upper1 ( s );
Console.WriteLine ( s );
TestClass tc = new TestClass();
tc.str = "lower 2";
Upper2 ( tc );
Console.WriteLine ( tc.str );
}
}
The output of this code on execution is as follows -
lower 1
LOWER 2
Press any key to continue
I am new to C# and totally confused over the outcome. As far as I know both "string" and "class type" are reference types in C#. When I am calling "Upper1" with a string as parameter it is behaving as if the parameter was passed "by value" and the changes are not visible in the calling function.
But if I wrap the string within a class and pass an instance of the class as argument to "Upper2", it is behaving as expected.
Can anyone help me in solving this mystery?
Thanks a lot in advance.
