I need implement a singleton in C#. I have tried making a static class but I seem to be getting members that go out of scope. What is the best was to do this? Thanks.

Here is a really good article on the Singleton Design Pattern.
Is show it in C++ and then the code convert as is to C# and then a better way of doing it in C# that takes advantage of the language. The C# way is easier. Take a look at the URL

When you run your application on XP it display in XP style,even it is C#,VC or VB programs.Maybe you change your Appearence to classic style in control panel

To clarify. XP style in terms of displaying the controls in the updated XP style as defined by XP's Common Control library and XP's current theme setting.
I'm new to C# and does not appear to be obvious how to achieve this. Or have i missed something?

In order to enable the XP Style controls you need to include a manifest either as a resource or as a separate file.
The manifest is nothing more than an xml document 
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly
xmlns="urn:schemas-microsoft-com:asm.v1"
manifestVersion="1.0">
<assemblyIdentity
processorArchitecture="x86"
version="5.1.0.0"
type="win32"
name="myapp.exe"/>
<description>your application description</description>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
publicKeyToken="6595b64144ccf1df"
language="*"
processorArchitecture="x86"/>
</dependentAssembly>
</dependency>
</assembly>
(manifest taken from Colin's VMTU since I can't find mine here)
If the manifest is included as a separate file (the easiest way to do it), it should be named myapp.exe.manifest
I can't remember the steps off hand for putting the manifest in the resource, i think resgenx was the command that was used to generate the resource, then you include the resource with the compiler.

And as Mazdak said, set the Appearance property to standard

Thanks for that info James and Mazdak!!! pointed me in the right direction.
Anyway for anyone who is still having problems displaying XP style controls. i found the following site on msdn useful.

hi,
I'm new to C#,I have this problem and would apriciate if someone would give me an idea .
I have a object initilazed in a Windows form and i wold like to use the same oject in some components and the way I was thinking was to get the address of this object. But since it's a managed object the compiler doesn't alow me to take it's address. 
Please give me any ideas to overcome this,
thanks a lot for your time

Like this:
SomeObject obj = new SomeObject();
Component1.Prop1 = obj;
Component2.Prop2 = obj;
All objects are refered to through "object references". You can freely pass this object reference to any part of your system.

Ok, quick question here -- I have VS.NET Beta 2 .. I've decided to start to get into C# and don't know much about it yet. Should I be using VS.NET Beta 2 or should I uninstall Beta 2 and install the latest release of the .NET Framwork SDK with the V1 of C# (since the C# language namespaces and the like have been re-arranged, I'm thinking that I should avoid learning the already outdated version).
On another note -- does anybody have the V1 C# compiling in their Visual Studio 6 IDE? If so are there some step-by-step instructions for implementing this?
Thanks in advance to all who reply,

I've started c# recently,and I use latest version of it,but the book I use for it is for Beta2 time.Up to now there were no problem and there is no difference.
I know that lots of namespace and ... changed from Beta1,not from Beta2

Ok, thanks .. I wasn't sure how much change there was between the Beta2 and V1 conversion, but apparently not as much as I thought.

Hi all,
I've a problem with Interoperability with Win32 unmanaged code; my C# program call an unmanaged function in a Win32 DLL and pass a pointer to delegate. This DLL every 20 milliseconds call my C# delegate but the win32 thread finish immediatally after createted. In the win32 function there is one FOR cycle that print a string in output debugger window.
Can you have some suggestion for solve my problem ?

Look at the Anchor property on the two textboxes. When a form is resized it will resize so that those edges (specified by the Anchor property) are always the same distance from the edge of the container.

I examine different Anchors for these "Multiline TextBoxes" but each time they move or resize wrong and hide other controls in the form.

To keep a control from moving, the Anchor property should be set to (AnchorStyles.Top | AnchorStyles.Left)
This will ensure that the control remains the same distance from the left and from the top.

One thing that always have confused me is why is the syntax "public class MyCLass" in C#?
What does it mean that "public" in the beginning of a class?

"public" is contrasted with "internal".
public classes can be accessed outside of the assembly that contains them. internal classes can only be accessed by other classes in the same assembly.
