Need a code sample.
How to recurse an Active Directory Security Group that contains other Security Groups as well as users. I need to create a full text listing of each user and all attributes available for that user. When I get the user collection now I get the Member groups. How might I recognize that one of the members is actually another Security Group?

If my program is running and I start a program such as Internet Explorer, how do I get the window handle of IE when my programs is activated and gets focus again?
I want to send keystrokes to differing programs. Currently, the only window I can get is the foreground window using the GetForeGroundWindow API when my program initially starts. If a new program starts while mine is running, in order to send keystrokes to it, I need to close my program and restart it, so I can get the new foreground window. Make sense?
Any ideas?

You can enumerate through the currently running processes and use the Process.MainWindowHandle[^] property to get the window handle. Something like
Process[] processes = Process.GetProcessesByName("notepad");
foreach(Process p in processes)
{
IntPtr handle = p.MainWindowHandle;
}

That doesn't help though. Within my code, I don't know which program just started or which program just had focus. It could be notepad, it could be IE, it could Vis Studio, or FireFox.
It doesn't matter what the program is, I want the window handle of the window that had focus prior to my program.

Unless your application is already running when the focus changes, there's no way to tell which application just had the focus. Your application will start way too late to get any notification of which window just lost the focus.

Yes, exactly. It will already be running.
Here's the example again. My program is running, but doesn't have focus. I start IE or MS Word and do blah blah blah in it. I click back or focus my program. What's the handle of the app that just had focus before mine?

There is no API call you can make to give you the last window that had the focus.
The only thing I can think of is to override the WndProc procedure in your main window and handle the WM_ACTIVATE[^] message. You'll have to track the window handle of the window that is being deactivated, then get the parent window of that window handle until you reach the top-level window handle of the application.

I couldn't seem to get that to work.
However, I did find another solution. I found a class that receives all mouse and keyboard events from the system.
I hooked up a couple events and now my program is told when someone clicks the mouse or presses a key. Then I just GetForeGroundWindow to get the active window and change the IntPtr my program is using to know what has focus.
Works great!

Hi,
the main question is: (see details and more detailed questions below)
"Is there any big performance difference on implementing
two services on the same service process instead of creating
two separate Windows services (each one on its own process)?"
Details:
I developed two Windows services that needed to share data.
One should be almost real-time (like a performance metrics
monitor). The other will transfer such captured data over
Web services, can be slow and should use data persistence.
Implementing separated services, I could do it with
MMF + P/Invoke, or use something elegant solution,
such as Natty Gur's (DevGlobalCache), found here at CP.
Alternatively, I could implement both services inside same
Windows service process. In such case I could leave MMF P/Invoke
(since it´s not native in C# == I´m using VS.NET 2003).
Though, I don´t know whether such alternative solution would
be feasible, due to the following doubts:
1. If a Windows service process has two or more services,
does Windows treat each one as a thread, or *only* the
entire proccess as a thread? If the second option is the
case, so both services cannot live on the same process
with no impact on performance.
2. On the other hand, if Windows doesn´t treat them as
separate threads, probably a Mutex won´t be necessary if
both as on the same process.
Any comments on this would be very appreciated.
Thanks in advance.
Eugenio

If you can run your services in the same process they will use fewer resources.
Each service is event driven. Don't count on the start and stop events to be called from the same thread. Other then those operations your service should manage it's own thread management. Either implicitly using a timer or other event object, or creating your own thread pool.

Is there a way to display a image on a Button with button.FlatStyle = FlatStyle.System. Currently I have applied XP theme to the controls.
|
|
|
|
|
Have you thought about just using a PictureBox control as your button? Or are you wanting the "effect" of a "downward click" when the mouse is clicked?
|
|
|
|
|
Yes. I need "downward click" "effect". When I do button.FlatStyle = FlatStyle.Standard, everything works fine but the look and feel of the button is like windows 2000 button.
|
|
|
|
|
Then I'm going to go with making a custom control that has the style + effect + picture.
|
|
|
|
|
Thanks for your time. Please see the next reply for an article on the same.
|
|
|
|
|
Heh, exactly what I posted except I didn't have an example...
|
|
|
|
|
Yes you did. Thats why I pointed you to the article. It might be useful for you also.
Anyway, thanks for your help.
|
|
|
|
|
Ohhh, ok.. well thanks for the info then and I'm happy to help (even a little) 
|
|

No. You have to implement this yourself. Check out this link.

I implemented something similar in a project.
I hope this helps.

Bingo.
This is exactly what I was looking for.
Thanks.

Is it possible to bind the text of a label to a variable so that if the variable changes, the displayed text on the label changes?
|
|
|
|
|
Sort of... one easy way to do this is to create a get/set for the variable and in the SET just change the text of the label as well:
<code>
private string myVariable;
public string MyVariable
{
get
{
return this.myVariable;
}
set
{
this.myVariable = value;
this.Label1.Text = value;
}
}
</code>
Now when you do something like: MyVariable = "Blah";
it will run through the "set" portion of the code and change the label as well as the internal private variable

[EDIT] Forget it, I don't think it will work the way you want.[/EDIT]
Does this work?
class MainForm : Form
{
string labelText = "Blah";
public MainForm()
{
InitializeComponent();
label1.DataBindings.Add("Text", this, "labelText");
}
