Typing "Classname." invokes intellisense which lists the properties and methods of that class or object so as to ease the work of a prorgammer so he/she does not have to remember all the properties and methods of the Dot Net Framework. There are many classes built into the Dot Net Framework, many of which wrap commonly used functionality that already exists in Windows. In summary, these classes and intellisense are there to make a programmer more productive and are part of the Dot Net Framework installed on your computer.
As for the difference between the methods displayed by Classes and Objects; Yes you are right that for Classes, only static methods are displayed unlike Objects.

Hi. I have a rss, and I want to remove the items that its pubDate are lower than a DateTime. The problem is that I can't use the function to compare date in XPath because the pubDate use the RFC-822 format and the function in XML/XSD/XSLT, use ISO-8601 format. So I have to use an external function to remove the nodes like this:
public static XmlDocument XMLFilter(XmlDocument doc, DateTime aDate)
XPathNavigator nav = doc.CreateNavigator();
DateTime nodeDate;
foreach (XPathNavigator node in nav.Select("rss/channel/item/pubDate")) {
nodeDate = DateTime.Parse(node.Value).ToLocalTime();
if (nodeDate.CompareTo(aDate.ToLocalTime()) < 0) {
node.DeleteSelf();
}
}
return doc;
}
But If I return the doc, the element are not removed. I want to remove that node (where I compare the condition node.DeleteSelf())
Thanks a lot !!!!!

Heyyy, I found the way !!! . Thanks anyway people !! May be this solution could help somebody, like me !! 
public static XmlDocument XMLFilter(XmlDocument doc, DateTime aDate)
{
DateTime nodeDate;
XmlNode nodeChannel = doc.SelectSingleNode("rss/channel");
XmlNodeList pudDateNodeList = doc.SelectNodes("rss/channel/item/pubDate");
foreach (XmlNode node in pudDateNodeList){
nodeDate = DateTime.Parse(node.InnerText).ToLocalTime();
if (nodeDate.CompareTo(aDate.ToLocalTime()) < 0) {
nodoChannel.RemoveChild(node.ParentNode);
}
}
return documento;
}

Hi.
When take right click on solution name in solution explorer, a choice is 'build solution', and another is 'Rebuild solution'.
What is the difference between them ?
Best wishes
|

Build just works on modified files, Rebuild deletes all object files etc, and does everything. I think.
Regards,
Rob Philpott.

Exactly. Build only builds the projects that has files that has changed since last build. Rebuild makes a complete build of the entire solution.

And one has to be careful with this. For example Visual Studio won't notice any changes made to resx files and won't build it until explicitely rebuild has been clicked.

If you want the user to be able to draw on a webpage and you save it, the only technologies I can think of which may let you do this are:
Applets (using Java)
and
Flash

Hi,
I am working on a VoIP application. I retrieve voice streams from a MIC. Now I would like to apply an audio codec (G711 or G729) on these streams.
I don't know where to start ...
Has someone an idea ?
Thanks in advance

I haven't worked on a project like this myself, so this might be a complete red herring - but I think the Windows Media Encoder SDK:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmencode/htm/aboutthewindowsmediaencodersdk.asp
should be helpful.

HI,
Thanks for that. I will have a look at it.

The link you sent is very good if you want to apply a codec that you "create" on your own. Thanks.
Although I would like to use an standard codec such as g711. So I have to look at something else.
I found that SUN release the code public :
Cpp : http://www.koders.com/cpp/fid45CC4E8F93239756E0CD455477269712A825C1E9.aspx
C: http://www.koders.com/c/fidCB98985908407980C619193ED46BC31B0535D651.aspx?s=g711.c
So I should be able to do something.
Regards

Hi All,
I'm currently messing with strings, and need your advice on how to do this more efficiently.
Some of the data I deal with comes as a huge line of text (2000 characters per record, approx 1000+ records per file... it's a bad system, but hey it's *worked* since 1986, apparently).
Now I need to be able to update certain segments of each record with new data, so I thought there must be some kind of .Net String replace method allowing you to specify a start and length of the characters you want to replace...
... only I haven'y found it yet! Instead, I'm having to cast each record out as a char[] and update each array element individually.
This works - but I suspect I must be missing a trick here, so does anyone know the proper way to do it?
Cheers,
Martin.

string test = "Paul Brower" ;
test.Replace("Paul","David") ;
//test now = "David Brower"
... go from there

Paul Brower wrote: test.Replace("Paul","David") ;
Just an oversight, I'm sure, but you need to assign the return value of all string methods to actually get the new value...
test = test.Replace("Paul", "David");
Normally I wouldn't point out such things, but since this is a "how do I use strings in .NET" question, I felt obliged to clarify.

No, there is no method for replacing a segment of a string, but it's easy to make one:
public string ReplaceSection(string data, int pos, string replacement) {
return data.SubString(0, pos) + replacement + data.SubString(pos + replacement.Length);
}
You might want to add some error checking to it, also.

StringBuilder Class
Namespace: System.Text
It has a Replace method with 4 overloads, and it is made for large strings - like you are working with.

There go my people. I must find out where they are going so I can lead them.

Try the following:
string s = "oldstring";
s = s.Replace("old","new");
If you look at the value of 's' it should now be "newstring".
I hope this helps.

Thanks for all the help here guys; I'm having a play with with the StringBuilder class' replace overload (StringBuilder.Replace Method (String, String, Int32, Int32)), as this seems to fit the bill - and is a lot more powerful than the generic String.Replace method.

Hi there.
I've found plenty of samples on how to implement dragging and dropping TO a winform in C#, and I've gotten that part to work. But the other way around (FROM a winform TO explorer) ... no luck 
I only found one article on TheCodeProject, but that was using C++ 
Any pointers or links would be very much appreciated.
Kind regards - Jakob
