Before I even start, I apologize for asking a NON-C# question in here. I've posted questions in nearly every forum in this site, and the responses in this one are by far the best. On that note, here is my question:
We have a situation at work where we've encountered a problem with accessing files which are located on another machine as the IIS server. We're using the File System Object to access these remote files. The problem is that the FileExists function always returns false for a file on another machine. This is a permissions issue, and I have some workarounds for it. Setting up a user account on the remote machine for the IUSR_COMPNAME account isn't really feasible, since this needs to be in commercial software, and the password for this account is generated dynamically. Yes, we could hack the registry and get this, but it's something we're trying to avoid. We could also have the ASP page start an external application to access the file, but again, we have the overhead of starting and ending a separate application, as well as the fact that we have to set up some way of giving this application the names of the actual files to access. I guess my question is, is there a method of doing this which actually works? If I search the web, I see that this issue has come up a lot...and the only real work-around I've seen is putting the IUSR account on the remote machine. Is there another way, and if so, what are the steps, or where can I find a quality article on this topic?
Again, while this isn't a pure C# question, it's still an issue that somebody using C# might face, so it's worth sharing. Thanks everybody.

I think if you are trying to do this with the ASP code you need to explicitely map the logical path to a physical one before trying the FileExists() function. Search on these lines.

No, it doesn't work by mapping to a virtual directory either. I wouldn't have posted this question if it were that easy...thank you though for the suggestion.

Hello,
Is there any property for numeric updown control in C# to make the text part of it to be invisible like we had in VB6.
Thanks,

string tempstr = "";
XmlDocument xml = new XmlDocument();

//m_value is object for serialize
Type objecttype = m_value.GetType();
PropertyInfo[] objectproperty = objecttype.GetProperties();
XmlNode node = xml.CreateNodeXmlNodeType.Element, "DataObject", "");
xml.AppendChild(node);
xml["DataObject"].SetAttribute("type", "object");
for(int i = 0; i < objectproperty.Length; i++)
{
object tempobj = new object();
PropertyInfo pi = objectproperty[i];
if(pi.Name != "Item")
{
tempobj = pi.GetValue(m_value,null);
}
//S is static method from DS class for serialize object that switch type of DataObject and then call S method recursively.
tempstr = DS.S(tempobj);
tempstr = "<" + objectproperty[i].Name + ">" + tempstr + "";
tempxml.LoadXml(tempstr);
xml["DataObject"].AppendChild(xml.ImportNode(tempxml.FirstChild, true));
}
return xml.InnerXml;

Hello,
I've tried filling a tree view with a large database on a worker thread (so my main window keeps responding.)
I get an InvalidOperationException saying that I'm doing it from the wrong thread. If I do it from the main thread, it is very slow, and can take up to 30 seconds.
Any ideas? Thanks,
-- LuisR

DISCLAIMER: I've never tried this so I don't know if it will work.
Would you be able to generate the tree structure first and then when your data loading thread is finished it fires an event to tell the main thread it is finished. The event handler then takes the nodes and attaches them to the tree control.
This would mean that for 30 seconds you have an empty tree control - but at least the application is responsive.

Mmm interesting idea... I'll give it a try! thanks!
During thos 30 seconds, I could fill the tree with a "Populating tree control, please wait..." node.

If you want to modify a control from a thread other than the thread that created it, you should use the Invoke method of the Control (in that case the TreeView) to invoke the function that adds the node to the tree. A simple example for adding a node which takes a string parameter for the node could be:
private void AddNode(string nodeText)<br />
{<br />
myTreeView.Nodes.Add(nodeText);<br />
}
then you can declare a delegate to call this function:
private delegate void AddNodeDelegate(string nodeText);
and then from any thread, you can safely do this:
string nodeText = "This is my safe node text";<br />
AddNodeDelegate myAdd = new AddNodeDelegate(AddNode);<br />
myTreeView.Invoke(myAdd, new object[] { nodeText } );

Hey all,
Work is really boring so I'm going to write a screen scraper. But the best say to do this is using Regex's, something I need to work on because it's a particular area of weakness. If a page has the following structure:
<html>
<head>
<title>foo</title>
</head>
<body>
<table><tr><td>foo</td></tr></table>
<table><tr><td>foo</td></tr></table>
</body>
</html>
Is there a regex I could use to pick up what's between the tags? Like a regex to grab the title, another for the first table, and the second?
Thanks much

Sure, here is a quick example so I am sure you can expand on it:
private void ShowContent(string s)
{
Regex r = new Regex("<td>*[a-z]*</td>", RegexOptions.IgnoreCase);
Match m = r.Match(s);
while(m.Success)
{
string val = m.Value.Delete(0, 4).Delete(m.Value.Length - 4, 4);
if(val != null)
Console.WriteLine(v);
m = m.NextMatch();
}
}

* is not a wildcard, though - you should actually just use "<td>[A-Za-z0-9]*</td>", which means that 0 or more alphanumeric characters (there are excape sequences you can use, too) are allowed between TD elements. What you have now will match 0 or more openning TD elements as well.

Regex can be horribly unreliable and a complete pain when unforeseen formats creep up. I recommend using SgmlReader[^] written by a fellow Microsoftie. HTML is, if you don't know, an SGML grammar, as is XML and XHTML (which is actually an XML grammar that only looks like HTML because it uses the XHTML namespace as the default namespace so that namespace prefices aren't required).

Hello,
I want to know, how can i enable/disable internet access to certain systems on the network ?

Don't cross post acrossed Forums. It's considered very rude...
There is no class to do this. The best way to do it is a Proxy server...

Hello,
how could one get tree folder browser in C#, like the one that Windows Explorer uses? I looked at all examples given, and have made my own version, but I can't get it to display Network Places. I can get the names of the all volumes connected (HDD, CDs, USB disks...), but don't know how to get Network Places.
So if anyone can point me the right way....
thnx,
ajvn
