I see.
I'm a begginer of C#. So far I don't know how to call a Windows API.
So I think I should learn more firstly.
Thanks all of you.

I see: if you want to read a single character from the user (any charachter, not an enter key press), and you don't want that character to be shown, the only way to do it on .Net 1.0 /1.1 (the 2.0 Console.ReadKey does the same thing) is to import _getch from msvcrt.dll.
You can use this code (by reinux from http://www.codeproject.com/useritems/PressAnyKeyToContinue.asp):
[DllImport("msvcrt.dll")]
private static extern int _getch();
public static int Getch()
{
try
{
return _getch();
}
catch
{
return Console.Read();
}
}
Insert this into a class and then you should be able to use Getch() to do what you need.
Bye!

I'm curious about DirectoryEntry.Properties["memberOf"] and "Domain Users". Let's assume that I know a little about AD and that I can properly get the DirectoryEntry to any domain user. Now, every group that the user belongs to is in the memberOf property except for one exception. "Domain Users", is it a special case? Is it implied that if I get a valid DirectoryEntry that, of course, the user is a member of "Domain Users" and therefore "Domain Users" isn't in the memberOf property?

Hi,
This is my first post here so please be gentle 
I know it is possible to copy config files into the GAC such that an assembly can read from it based on its own location. This avoids having to partially hard code a location for the config file. However, is this good practice? What is the best approach for doing this?
Thanks in advance

Really? I thought GAC stood for "Global *Assembly* Cache"?

<I though GAC stood for "Global *Assembly* Cache"?>
Precisely my point, hence why I asked if this was good practice and if there was a "good" way of referencing configuration information from the GAC.
If the only solution is to hard reference the config file then that is what I have to do. However, if there is another way, then I would really be interested.
Btw - thanks for the reply 
P.

Anyone know how to programitically switch language when the focus hits a textbox? I am writing a dual-language application and want to switch to Thai from English when the user tabs into a textbox, rather than have the user goto the language bar to do so....
Thanx!

I'm writing a program (Vis. C# .NET) to move files, depending from content, to a backup server. Sometimes the file cannot be deleted afdter copying because it is opened by an other process. The best would be to have a test a first that gives me a result if a specific file is opened by an other process or not.
How this can be done ? At least I need a boolean answer if the file is opened in this moment by anything other or not. The better way would be to have an answer which process has opened it.
Can anybody give me a hint for a good solution ?

I would think that you could just try to open the file for exclusive read access - that should throw an exception. As for the ultimate, you would have to use interop and Win32 functions to delve into the finer details. The OpenFile() Win32 function might do a better job than .Net for what you want. This site really helps with the interop stuff....

No, MD5 is a hashing algorhitm. Its intended to be one way.

Add a reference to the DLL, and Interop DLL's/Wrapper classes are automatically generated for you - then just make use of the objects in the namespace by the LIB name - class viewer will help you find the generated namespace and object names.

(Please note: I am NOT looking for a ready made control library to pop into an application. I would like to understand how to do this for myself.)
I've searched the .NET fora for an article on implementing dockable windows/forms but wasn't able to find the right info and was wondering if you could help me.
This is what I want to do:
Similar to the VS.NET GUI, I would like to define behaviors for child MDI forms such that if they are moved over certain regions, they should dock in those regions.
The behavior that I desire is identical to that of "Soultion Explorer", "Toolbox" etc in VS.NET.
I have learnt how to spawn child MDI forms. I'm using Visual Studio .NET 2003.
Your pointers, code and any help are much appreciated!

What exactly do you want to know? To accomplish docking is not a trivial task. Although you mentioned you don't want a complete control library I suggest looking at this[^] article. You can look into the code and learn everything you need.

In VB6 i could instantiate a class in a module as public and this would become global to the entire application. This was useful for a settings class where the settings were loaded from a file when the app started, then classes would share these settings and modify them, then the settings file would updated when the app closed.
Is there a way to do similar in C#? Where do i need to put the settings class so that it is global to all other classes in a namespace?

I use a class to hold all my "global" settings which i load on application startup. These values are accessable from anywhere in the app. Heres how you do it:
1) Create a class which is public
2) Add public static variables where you will store your settings.
public class Globals<br />
{<br />
public static bool bBoolvalue;<br />
public static string sStringValue;<br />
<br />
public Globals()<br />
{<br />
}<br />
}
3) Then when you app starts up - just assign values to these variables
eg: Globals.sStringValue = "This is a string";
4) This variable will now contain the assigned value and because it is public static you will be able to reference it from anywhere in your app eg: string sTest = Globals.sStringValue;
Hope this helps,
Cheers

Craig,
Thanks for the advice. Coming from VB6, i did not use static all that much. I took your static idea one step further and used it with properties and methods so i could duplicate what i did in VB6. It works!

This is my situation.
I am creating an instant messenger
I have a main method which calls application.run(new form1())
This launches my main form.
I start another thread in my form1 constructor that sits in the background and soley listens for incoming connections
code:
public form1()
{
InitializeComponent()
Thread t = new Thread(new ThreadStart(ListenNewConnections));
t.Start();
}
When thread t finally gets a new connection that thread itself shoots off another thread "A"
to handle that particular connection thru out its life span. Once that connection is done so is the thread.
Now when thread "A" is handling a specific connection I want it to create a form - this is where the problem starts.
1st thing i did
newform.Show() - creates a blank form and when mouse over u get hour glass
I think the reason for this is because it is not starting on the main thread for message pumping.
Ok so second thing i do is use a delegate
this.BeginInvoke(new createFormdelegate(createForm)); //create form method simply initializes a new form and calls newform.Show().
but when i debug it stops at the this.BeginInvoke line an gives me this error
"Invoke or BeginInvoke cannot be called on a control until the window handle has been created."
I know i am doing something wrong. Maybe my c# logical thinking is off i dont know.
Please help
Thanks in advance

This being your worker thread:
private static void ShowMyForm()
{
frmMyForm frmg = new frmMyForm();
Application.Run(frm);
}
If you want to make any calls that are thread dependant (on the window handle), like calling from one thread to another to set the focus of a control, that is when you use BeginInvoke. As the error points out, you can only call BeginInvoke when all handles are created.

I dont understand?
1> what is the window handle? how do i know it is created? how do i create a handle?
jonny5 wrote: private static void ShowMyForm()

Are you telling me to call Application.Run(newForm) everytime i create a new form.
Keep in mine everytime a new connection comes in a new thread and form is created to handle
that connection and communication between the two endpoints.
I thought Application.Run() was to be only called once???

I thought that is what i was doing in the code i showed...maybe not could you explain because
i was trying to create and set focus the new form with the BeginInvoke.
please help still confused.
Thanks alot!
