I have set up a simple application to connect to the internet and download the contents of a file from time to time, for example a file containing quotes that are to change on daily basis.
This has been set up correctly - the connection is made (using HttpWebRequest and HttpWebResponse...) and the contents are downloaded  . However, running the application more than once will than display the same contents that were first downloaded. This can go on from a few hours to a few days!  I don't know what is going on, but I believe that the program is accessing some cache from somewhere instead of downloading the stream once again.
I need the program to download the stream from the internet every time it is running - and ignores any cache or whatever it is that is storing the stream data. What am I to do?

Change the CachePolicy[^] of the HttpWebRequest.

I looking for some way to show ip address in my UI ( Win Form ).
I don't find it in the standard controller of VS 2008.
I need something simple - like UI ip controller that was in MFC.
Someone can help ?
How can i find it in VS2008 ( C# )

I don't believe there's a built-in WinForms or WPF IP address control. But a quick google search reveals several articles on this site that show how to create one.

If you download Expresso ( www.expresso.com ) it will help you learn how to use regex. It probably has a sample regex in it for URLs, too.

Hi maby someone can help me with this... I wrote a silverlight chart that gets it's data from a wcf service using linq to sql the following code fails and I have no idea why.
DataClasses1DataContext db = new DataClasses1DataContext();
var speeds = db.sao_GetMonthlyInterfaceData(Convert.ToInt64(code), routerSpeed, dateFrom, dateTo);List<String> values = new List<string>();
List<sao_GetMonthlyInterfaceDataResult> sp = speeds.ToList<sao_GetMonthlyInterfaceDataResult>();
IEnumerator<sao_GetMonthlyInterfaceDataResult> enumerator = sp.GetEnumerator();while (enumerator.MoveNext())
{
sao_GetMonthlyInterfaceDataResult val = ((sao_GetMonthlyInterfaceDataResult)enumerator.Current);
String ret = "";
ret += Convert.ToString(val.BpsIN );
ret += " ";
ret += Convert.ToString(val.BpsOUT);
ret += " ";ret += Convert.ToString(val.UpdateTime);
values.Add(ret);
}
return values;
</pre>
Maby someone out there can help with this.
Thanks

It's hard to diagnose a problem with no description of what line in particular is failing as well as what message you're receiving.

When running the app I get the following. In the previous code if I remove the LINQ call the error seems to disapear... Sorry for not including the error, after looking at this code for the time I have one tends to forget that everyone doesn't have the same problem.
Thanks

Hi All,
I'm trying to create an event that the standard ListView doesn't have: fired after a vertical scroll has occured (By pressing arrow key down, arrow key up, mouse click on the vertical scroll bar or by the mouse wheel scroll).
Even when ignoring the mouse events, catching the KeyUp or KeyDown events is not good enough since it's raised before the TopItem change takes place, and not after.
An altenative can be an "TopItemChanged" event, which is raised whenever the TopItem is cahnged. I don't know how to implement this one either.
Thanks a lot!
Eyal.

Good Day,
If I want to check if a path is a File or Directory, I always use the Path.HasExtension function. If it have an extension, it is a file. Otherwise, it is a directory.
Just recently, I found out that this is not really effective for Files that doesn't have an extension and for directories that have an extension.
So How can I really really tell if a path is a File or a Directory?
PS: I can't use File.Exist or Directory.Exist.
Thanks!

Well you could use...

Damn, why not?
How about
DirectoryInfo DI = new DirectoryInfo("C:\\thing");
if(DI.Exists)
else
It's exactly the same, but different 
I can't think of any other way of the top of my head.

Well, the path that I am testing does not really exist. It's hard to explain.
Just think of it as a "programming exercise" given in school and you have to type a random path and tell if it is a file and a folder.

Your teacher is a retard. If the file doesn't really exist, and you can't use the presence of extensions to tell, then there is no real solution.

No, its not a school activity. I just made that up to simplify the matter.
Well, this is the real scenario...
I have a function that "ROLLBACKS" files and folders. I have a special routine for files and special routine for folders. Those files and folders does not exist yet, that's why I can't use the .Exists() method.
I just want a function that accepts a PATH and returns if it is a folder or file.
Sorry for the confusion.

Not possible, for the reasons stated. Your best bet is to assume an extension means it's a file.

As has been pointed out, there is no way to tell if a path is for a directory or file UNLESS there is a directory delimiter (slash) at the end. This isn't guaranteed by almost any function, though.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hello,
I have a main form that contains many form. When i am trying to close the main form by the X control box button, the onformclosing event of the child forms are launched before the main form event (onclosing) are launched.
How can i capte the X button closing in the mainform first?
best regards,
dghdfghdfghdfghdgh

The main form is closing it's children first. This is logical. I am not sure if you can do anything about it.

You can check the FormClosingEventArgs in FormClosing. Allows you to cancel closing the form. I don't really know if the child forms will stay open, but it sounds logical that they will.

You can turn on double buffering,
this.SetStyle(
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.DoubleBuffer,true);
