How can I return the method that is called when an event is raised ?
System.Reflection.EventInfo.GetRaiseMethod does not work.

Are you looking for the method name? Or, a reference to the method?

I nead the method as System.Reflection.MethodInfo

Right off hand, I don't know. I would say that you can create a custom exception that passes the value, but I'm sure there's a better solution than that.

i have a asp.net c# project i connect to on a remote server from home. it opens fine but when i compile i get can't save to webserver .pdb(my local vs cache). first thing i do when project opened is sync all folders. any ideas.
ps only iexplore supports reg exp validator control, meaning that in netscape you must use the this.validate(), then this.isValid calls to make it work. I think this is a valid lawsuit for microshit.

Hi there,
On the login page of our .aspx intranet application, we use the system.directory namespace to query active directory using the username and password entered on the page. Something like the following.
oRoot = New DirectoryServices.DirectoryEntry("GC://dc=acme,dc=com, <username>,<password>)
oSearch = New DirectoryServices.DirectorySearcher
oSearch.SearchRoot = oRoot
oSearch.Filter = "(&(objectclass=user)(sAMaccountName=jbloggs))"
oResults = oSearch.FindAll()
We use GC:// instead of LDAP:// because we want to do a forest wide search as we have multiple domains. We have 3 Global catalogs within our network infrastructure. Most of the time this piece of code works find. But sometimes with no consistency, the application throws an error on the last line of the above code (oSearch.FindAll()). The error reported is 'The server is not operational'. Does anyone have any ideas, how does FindAll() work?
Thanks
Cammie

Greetings,
I am writing a program that installs an assembly into a remote machine GAC.
I am using the OpenRemoteBaseKey method to get the drive letter and path to where the .NET framework is installed. Now it works fine as an administrator going from one machine to another. But when I am a user it does not work. Okay I am fine with that.
How can set the security prinicple with this method to impersonate a adminstrator, whilst execute as a user?
I have the creditials that I need to pass in the process from an encrypted app settings file.
Thanks in Advance.
Cheers,
Campbell

You should really not be allowing applications to install anything in the GAC as a user level account. In fact you should not be allowing user level accounts to install applications at all 
But if you must .....
To impersonate a user you need to use P/Invoke to call the LogonUser API from advapi32.dll to get a user token. Then you need to create a new WindowsImpersonationContext from this user token and call the Impersonate() method. After you've done the dirty work you should call Undo() to revert back to user level. And now an example: Windows Impersonation MSDN Example[^]

Okay. I had a look at the code and it makes sense. But where is the password passed, I saw the domain and username. Is that part of the LogonUser unmanaged method, using the interactive logon flag constant?

YOu can use the interactive logon flag to make windows bring up the password entry box, but if you have your own means of obtaining the password you can pass the password into the password parameter of LogonUser function and not specify any flags.

Can one unload an assembly?

No one cannot unload an assembly, but one can unload an AppDomain into which an assembly was loaded

Does any one know how to prevent a Windows Form from showing at startup. I've tried making the form hide inside my Load event, and tried to make it invisible inside my constructor and many things. I can make Main inside another class, but that makes a console appear instead.
I just want nothing to appear, except my notification icon. How would I go about this?
Thanks,
Shane S. Anderson.

I thought there was a way of doing this -- at least a better one than I've come up with...
Here's what I did (which is trick the form into submission):
In the form properties browser, I set opacity to 0%, then in the declarations sections of the class:
private bool loadedActivated = false;
and in the body of the Load and Activated methods:
private void Form1_Load(object sender, System.EventArgs e)
{
this.Visible = false;
}
private void Form1_Activated(object sender, System.EventArgs e)
{
if (!loadedActivated)
{
this.Visible = false;
loadedActivated = true;
}
}
and lastly in the the NotifyIcon Click (or double-click, if you prefer):
private void notifyIcon1_Click(object sender, System.EventArgs e)
{
this.Opacity = 1.00;
this.Visible = true;
}
... so I'm looking forward to someone who has a better, more elegant solution.

.Net is not supported on NT4, ME ore win98, so the answer is no.

That's simply not true!
Microsoft .NET Framework can be installed on the following OS (hence applications will run on these operating systems):
Microsoft Windows® 98
Microsoft Windows NT® 4.0 (SP 6a required)
Microsoft Windows Millennium Edition (Windows Me)
Microsoft Windows 2000 (SP2 Recommended)
Microsoft Windows XP Professional
Microsoft Windows XP Home Edition
HOWEVER! ASP.NET is NOT supported on anything below Windows 2000 ..... and the Visual Studio .NET 2003 will NOT install on anything below Windows 2000. But ALL compiled applications will run happily on anything above and including Windows 98

I can vouch for that; I've run a .NET program fine on a Win98SE computer.

Check out the other answers in this thread -- but also read MSDN on the limitations of .NET on particular platforms.

I'm programming VB.NET and my application has an open ODBC connection to a remote database (MySQL) server. I'm using the .NET framework with data adapters, data sets etc.
Now, my application needs to some how be notified when the database has been changed (for example by another client running on another computer). Some kind of notification from the server to the client upon database change. There must be some way to do that, right?
I hope there is someone who can help me with this. Thanks!

I've never used MySQL so I don't know if it will work. Does MySQL support the concept of Triggers? If so, it may be possible to write one that will notify the client somehow.
