Nick,
Thanks for the response, but I have used Reflector for a long time but that is not what I need. I am exposing an object configuration editor for our proprietary web engine. I am trying to create an editor that is launched from the propertyGrid in my application so that when a developer wants to define a new object to our engine, they do not have to type all of the XML by hand and run the risk of errors.
Thus, I need them to point me at the DLL. Then I can expose the classes. And when they choose the class I can issue a System.Type.GetMethods() to let them choose which method to execute. Then, when all of the information is selected via dropdown boxes, I can format the proprietary XML file to define this object to our web engine.

I was only suggesting that you take a look at the decompiled source for reflector within reflector to see how to do what you need as it does what you are asking.

Good idea!
Thanks.

See the Assembly class for a list of methods. Nick's right, though - why do something that several other people already have? And .NET Reflector has been in development for a couple years, IIRC.
You could also just use ildasm.exe, the IL disassembler that comes with the .NET Framework SDK. No decompilation, but any developer worth his/her salt should be able to read and understand IL, IMO.

The reason I am doing it myself is because those tools do not take the selected results, put it into the XML file format that our proprietary web engines uses, and properly integrates it into the AppVarConfig and GlobalObjectConfig files of our application.
I have been reading through the Assembly class for a list of methods and quite alot of it is very genereric:
Assembly.SomeMethod returns the attributes of the instance.
Okay....are we talking the instance of the Assembly or the instance
of the object I am working with?
Are they talking about characteristics (like methods) or are they
talking about true attributes ([Description("")]) which I do not need?

Assembly represents your assembly. What don't you get about that? It contains modules, assembly attributes, and embedded resources all listed by a manifest. The Assembly class gives you programmatic access to all that.
If you wanted to get all public and protected Types in your assembly, use Assembly.GetExportedTypes. If you want the assembly attributes, use Assembly.GetCustomAttributes. If you want all types defined in the assembly use Assembly.GetTypes. Trying to get a reference to the Assembly instance? There's static methods to do that as well. You can also use obj.GetType().Assembly or typeof(MyClass).Assembly.

Make sure you use Assembly.GetExportedTypes to get the types...

Seems I found the issue that was confusing me.
Once I pointed Reflector at the DLL I was testing against it, too, reported problems with the GetExportedTypes(). However, Reflector was able to trap all of this one at a time and report back where it was having problems. In this case, a number of DLL's marked Do Not Copy.
So once I pointed at a known DLL that had everything there, both Reflector and my code worked.
Thanks Nick and Jonathan for your help.
ANSWER:
I created a FileDialog object (named getModule) with my form. A button next to a textbox allowed the developer to point at a particular DLL.
The classes are displayed in a combobox. Here is the code:
this.getModule.ShowDialog(this);
this.moduleID.Text = getModule.FileName.Substring(getModule.FileName.LastIndexOf(@"\")+1,
getModule.FileName.LastIndexOf(".") - getModule.FileName.LastIndexOf(@"\") - 1);
Assembly developerClass = Assembly.LoadFrom(getModule.FileName);
Type[] data = developerClass.GetExportedTypes();
classID.BeginUpdate();
classID.Items.Clear();
int len = 0;
foreach (Type objType in data)
{
classID.Items.Add(objType.Name);
if (objType.FullName.Length > len)
len = objType.FullName.Length;
}
classID.EndUpdate();

 How can I view all the connections to a .NET Remoting server? I've browsed through the .NET Remoting namespace to no avail. I know I could call a method on an exposed object to do reference counting, but I wonder if there's a better way to find the sockets that are currently connected and get their IP addresses, etc.

I am not quite sure how you may do this...an awful lot is externalized away from the remote object. Good for quick deployment....bad for what you are trying to do.
I can, however, point you in a good direction. I suggest you run out to the Ingo Rammer website and pose your question directly to him.
His website is : http://www.ingorammer.com/RemotingFAQ/[^]

It does. Search in C# section shell programming and you wuill find sme articles there.

Getting the open windows has nothing to do with the shell - that's a function of the window manager. You can use System.Diagnostics.Process.GetProcesses to get a Process[] array. To determine which running processes are window applications, enumerate the array and check Process.MainWindowHandle to determine if it is IntPtr.Zero (not a window application) or not (a window application).

but this code is good to get the process not the applications so
if the opened windows ("c:","MyComputer")only one process will appear under the name of Explorer
so wt can we do ??

If you have the option set in Windows Explorer for each window to be opened in a separate process, this will work. If not, you'll have to P/Invoke EnumWindows and create an EnumWindowsProc delegate (not necessarily by name but by signature).
There's already been several articles outlining this here on CodeProject, so instead of explaining it just see the highlighted portions of Window Hiding with C#[^].

Hi again,
A few days ago I had a "rectangle drawing problem". I transformed my whole project and made my own custom control so I could draw my carpets and rectangle in the order I wanted. This works now. I also noticed that I use far less resources for the VisualShed to be drawn...
So now that I can draw my rectangle on the Graphics object of the shed, I'm trying to make a scale function that zooms in on the selected rectangle. I _googled_ and _code projected_ to find a solution. On codeProject I found an application that solves my problem. Not completely though.
http://www.codeproject.com/cs/media/limf.asp?target=displayport[^]
The problem here is that you can make a "rectangle zoom" on an Image. But not on the Graphics object itself. I also think that this application is far to complex for what I'm trying to do.
Can someone give me a hint on how to do it?
Thx in advance!
Kind regards,
TweeZz.

You can use graphics.ScaleTransform() to do the zoom and graphics.TranslateTransform() to reposition on specific part of your drawing surface. You have to make those call to graphics before any drawing occurs. To make the zoom 200% you do graphics.ScaleTransform(2.0, 2.0)
You can lookup more documentation on this at graphics class.

Does the VC#.net package on market contains the compact framework
so I don't need to buy the whole VS studio .net for programming CE

Hi!
I am developing a web application in asp.net using C#. my problem is that i take user input and store it into database. Now when i take the input for "salary". from a text box i am unable to convert it into "Money data type".
my code is
string sql="insert into User1 values ("+txtUser_ID.value+", .... ... ','Cast('txtSalart.value' as Money)','.....
I hav tried several other combinations as well but each time i get the errors like
1. Invalid character near txtSalary,
2. Can not convert to Money from varchar Use CONVERT function
anf bla bla....
Similarly what should i do to store date without a time value. ie i just want to store date n not time. and also i want to retrieve only date value and not time....
Can any one help me out ???

To convert to money data type you can use:
decimal amount = Convert.ToDecimal(txtSalary.value)
then you can use amount.
Best way to do that would be to use parameterized query instead of creating sql as string.
cmd.Text = "insert into user1 values (@col1, @col2)";
cmd.Parameters.Add("@col1", txtUserID.value); // if it's a string
cmd.Parameters.Add("@col2", amount);

To get the date only part of datetime you use Date property.
DateTime someDate = ...;
DateTime dateOnly = someDate.Date;
