I've been trying to read that code, but I'm not getting anywhere with it. I've been debugging it hoping to see something that would do the trick for me, but it doesn't work per design when you debug it. Only when you actually run the code without interruptions it does the trick.
Maybe I'm doing something wrong...

Are you writing both apps ? If not, you have to find the window and get it's text.

Hello Christian!
I'm writing the "application B", "application A" is being developed by somebody else.
If I am not mistaken, I can use some Windows API to find the window id of the object I'm interested in. I can definitely get the window ID of the parent window (using Process class) and then drill my way down.
Thanks.

Yes, you can get the top window and search from there. It's messy, but it can be done.

There's also an API called something like 'windowfrompoint' if you can ask your user to click on the window you want to find.

Christian,
OK, thanks! I'll look into that call too.
So, is there a way to get and "grip" on the object (so that I could use Reflection on it) based on a window handle?
Thanks.

I came across this error in my code that I cannot fix:
A field initializer cannot reference the non-static field, method, or property 'ConsoleApplication.Polygon.colorValues'
So extracted what I thought was the relevant part of the code to post and ask for help. The problem is that now this simplified code works . But I cannot find the problem in the original, full-length code.
Since the original code is too long to post here, I was hoping I could post the "working" code here with the error. Maybe someone could tell me at least what to look for.
This is my working code.
The code creates a class with two fields. Both fields are enumerations...
using System;
namespace ConsoleApplication
{
class Program
{
enum ColorType {Red, Green, Blue, Yellow};
enum ShapeType {Square, Circle, Triangle};
class Polygon
{
public ColorType Color { get; set; }
public ShapeType Shape { get; set; }
private Polygon() { }
public Polygon(ColorType color, ShapeType shape)
{
Color = color;
Shape = shape;
}
}
The code then tries to create an array of these classes. The elements of the array contain each possible combination of the enumerations. To do that, I use Enum.GetValues() to get an array of possible enum values and use the Array.Length property to figure out the size of the array I will need to hold all the combinations.
static void Main(string[] args)
{
Array colorValues = Enum.GetValues(typeof(ColorType));
Array shapeValues = Enum.GetValues(typeof(ShapeType));
Polygon[] allPolygons = new Polygon[<code>colorValues</code>.Length * <code>shapeValues</code>.Length];
int index = 0;
foreach (ColorType color in colorValues)
{
foreach (ShapeType shape in shapeValues)
{
allPolygons[index] = new Polygon(color, shape);
Console.WriteLine(allPolygons[index]);
index++;
}
}
}
}
}
I underlined the portion (above) that is generating the error:
A field initializer cannot reference the non-static field, method, or property 'ConsoleApplication.Polygon.colorValues'.
Unfortunately, this code works but the real code doesn't. Can someone help me interpret what the compiler might be having a problem with so I know what to look for?
Thanks.

Your code works probably because you moved initialization of colorValues inside Main. Your original code probaly initialized them as part of the field declaration, like
class Program
{
Array colorValues = Enum.GetValues(typeof(ColorType));
Polygon[] allPolygons = new Polygon[colorValues.Length * shapeValues.Length];
}
That doesn't work - instance field initializers cannot refer to other instance field initializers. That means that you cannot refer to colorValues from any other instance field initializer.
The typical solution is to move the initialization code to the constructor of the class.

Cool. Moving the initialization of colorValues, shapeValues, and allPolygons to the constructor worked. Thanks.
I think the full code design is "cleaner" when I declare the colorValues/shapeValues arrays as static (as mentioned below).
Thank you everyone.

Okay, I think it is the "cannot reference the non-static" part of the error which is relevant.
If I move the Main() code into a class:
class MyClass
{
Array colorValues = Enum.GetValues(typeof(ColorType));
Array shapeValues = Enum.GetValues(typeof(ShapeType));
Polygon[] allPolygons = new Polygon[colorValues.Length * shapeValues.Length];
public MyClass()
{
int index = 0;
foreach (ColorType color in colorValues)
{
foreach (ShapeType shape in shapeValues)
{
allPolygons[index] = new Polygon(color, shape);
Console.WriteLine(allPolygons[index]);
index++;
}
}
}
}
...and call it from Main()
static void Main(string[] args)
{
MyClass myClass = new MyClass();
}
I get the error. But how do I work around that? How would I create the private allPolygons array? What am I actually doing wrong?

Seems to me like these should be static anyhow, they don't change between instances, right ?

Just move the code to the constructor and you'll be fine
class MyClass
{
Array colorValues = Enum.GetValues(typeof(ColorType));
Array shapeValues = Enum.GetValues(typeof(ShapeType));
Polygon[] allPolygons;
public MyClass()
{
allPolygons = = new Polygon[colorValues.Length * shapeValues.Length];
...
}
}

If a method is static, it can't access a non static property as it has no instance to refer to.

Hi
Thanks for existing, as I would be totaly lost without you and others willing to share.
I am a beginner and need help.
I get this error when running the following to get members fo the Administrators group.
"Compiler Error Message: CS1519: Invalid token 'foreach' in class, struct, or interface member declaration"
I want to learn to access AD via C# and am having fits.
Thanks for being there.

DirectoryEntry localMachine = new DirectoryEntry
("WinNT://" + Environment.MachineName + ".");
DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName);
DirectoryEntry admGroup = localMachine.Children.Find("administrators", "group");
object members = admGroup.Invoke("members", null);
foreach (object groupMember in (IEnumerable)members)
{
DirectoryEntry member = new DirectoryEntry(groupMember);
Console.WriteLine(member.Name);
}}
End if

IT needs to be in method or some other class member. EG:
class Foo
{
void Bar()
{
foreach (var a in b) ...
}
}

Hi
Thanks for your reply.
I tried:
<%@ Page Language="C#" %>
<% using System.DirectoryServices %>
<% using System.DirectoryServices.ActiveDirectory %>
<script runat="server">
DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName + ".");
DirectoryEntry admGroup = localMachine.Children.Find("administrators", "group");
object members = admGroup.Invoke("members", null);
void Bar()
{
foreach (object groupMember in (IEnumerable)members);
DirectoryEntry member = new DirectoryEntry(groupMember);
Console.WriteLine(member.Name);
}
And got this:
Line 8: DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName + ".");

My guess would be a missing bracket somewhere in the file, probably before the foreach statement.

If you are in VS, just press F1 to take you to the error documentation, it normally contains samples of what went wrong.

I added a variable of type string to a class. I added getter and setters. Should new be called (for instance in constructor) before assigning it a value?

You mean like?
string foo = new string();
foo = "bar";
While I have seen this a lot, it is in fact completely absurd!
