<br />
string s= @"<here is='a little' bit='of'>xml</here>";<br />
Regex rx=new Regex(<br />
	@"(?<tag><)((?<prequote>.*?)')+(?<tag>[^']*?>)",<br />
	RegexOptions.Compiled|RegexOptions.ExplicitCapture|RegexOptions.Singleline);<br />
string results=rx.Replace(s,new MatchEvaluator(this.tagEvaluator));<br />
Console.WriteLine(results);<br />
<br />
<br />
	string tagEvaluator(Match m) {<br />
		string r=m.Groups["tag"].Captures[0].Value;<br />
		for (int i=0; i< m.Groups["prequote"].Captures.Count;i++) {<br />
			r+= m.Groups["prequote"].Captures[i].Value + "\"";<br />
		}<br />
		return r + m.Groups["tag"].Captures[1].Value;<br />
	}<br />

So here it is with codeproject.com formatting:

string s= @"<here is="a little" bit="of">xml";
Regex rx=new Regex(
@"(?<tag><)((?<prequote>.*?)')+(?<tag>[^']*?>)",
RegexOptions.Compiled|RegexOptions.ExplicitCapture|RegexOptions.Singleline);
string results=rx.Replace(s,new MatchEvaluator(this.tagEvaluator));
Console.WriteLine(results);

string tagEvaluator(Match m) {
string r=m.Groups["tag"].Captures[0].Value;
for (int i=0; i< m.Groups["prequote"].Captures.Count;i++) {
r+= m.Groups["prequote"].Captures[i].Value + "\"";
}
return r + m.Groups["tag"].Captures[1].Value;
}

Could someone tell me how to fire off a menu item click event from a UserControl. The menu is contained in the UserControls parent form.

Thanks,
Paul

if you have for instance a menuFileOpen_Click method for you file open on your menu and you wanted to use it for an open button you would just assign it to the buttons cick handler.
btnOpen_Click()
{
menuFileOpen_Click();
}

I hope that is what you ment.

Quoted from MSDN:

The Path property uniquely identifies this entry in a networked environment. This entry can always be retrieved using this Path.

Setting the Path retrieves a new entry from the directory store; it does not change the path of the currently bound entry.

The classes associated with the DirectoryEntry component can be used with any of the Active Directory service providers. Some of the current providers are Internet Information Services (IIS), Lightweight Directory Access Protocol (LDAP), Novell NetWare Directory Service (NDS), and WinNT.

Note The portion of the Path that identifies the provider (precedes "://") is case sensitive. For example, "LDAP://" or "WinNT://".
The syntax for the Path property varies according to the provider. Some common scenarios are:

WinNT

Connect to a group on a computer. For example, "WinNT:// domain/ computer/ group ". If you are connecting to a local computer, "WinNT:// computer/ group ".
Connect to a user on a computer. For example, "WinNT:// domain/ computer/ user ". If you are connecting to a local computer, "WinNT:// computer/ user ".
Connect to services on a computer. For example, "WinNT:// domain/ computer/ service ". If you are connecting to a local computer, "WinNT:// computer/ service ".
Discover all domains on the network. For example, "WinNT:". The domains can be found by enumerating the children of this entry.

LDAP

Connect to a group in a domain. For example, "LDAP://CN= group-name, CN=Users, DC= domain-controller1, DC= domain-controller2,... ".
Connect to a user in a domain. For example, "LDAP://CN= full-user-name, CN=Users, DC= domain-controller1, DC= domain-controller2,...".
Connect to computers in a domain. For example, "LDAP://CN= computer-name, CN=Computers, DC= domain-controller1, DC= domain-controller2,...".

IIS

Connect to a Web directory. For example, "IIS://LocalHost/W3SVC/1/ROOT/ web-directory-name ".

When I do this to one of my projects

using System.Messaging;

I get the following error :

The type or namespace name 'Messaging' does not exist in the class or namespace 'System' (are you missing an assembly reference?)

What the heck is wrong with this picture ?
I am actually missing the namespace ?????
It's all over in the help system. It can't be missing!

Can someone please help me out ?

tia,

Pilgrim

You need to reference the assembly containing the System.Messaging namespace, in this case "System.Messaging.dll".

In VS.NET, right click on the "References" entry for that project and choose Add Reference. On the command line add "/r:System.Messageing.dll"

Views in C#

Hi all,

Is there a way to keep the same form (title bar, menus, etc.) but dynamically change the client area and event handlers? You know, like the MFC CView class.

I would like to have a SDI application that changes the view based on a menu selection. Do I have to create a different forms for the different views, but add the same title & menu? Confused | :confused:

SimonS16-Nov-02 19:32

What about using Forms inheritance?
Then just expose additional methods/properties to handle the delegates.

Cheers,
Simon

SimonS suggestion would work, but might be too much work in the end, rather than using Inherited Forms I'd go with a UserControl that implements the base functionality you need for the client area and event handlers (with the event handlers being marked virtual).

Then for each 'view' create a new UserControl which derives from the base control created above. And replace the previous one that was there (unhooking/hooking up the event handlers as you go).

i face some problem when 2 thread trying to access a file at the same
time.
for thread X, it trying to access the file with:
-------------------------------------
b.Save("ref.jpg);//b is Bitmap object
-------------------------------------

while at the same time, the thread Y will trying to access the file
with:
------------------------------------------------------------------------
FileStream fs = new FileStream("ref.jpg", FileMode.Open,
FileAccess.Read, FileShare.Read);
------------------------------------------------------------------------

thread Y sometimes will halt at FileStream fs... line without execute
the next statement. i strongly suspect that it is because that i
trying to access the same file at the same time.

any suggestion in solving this problem?

thank you.

regards
