Upon first pass it appears as thought the dotnet framework is no longer embedded and automatically deployed with VS.NET microsoft installer deployment projects as it was in Release Candidate 1. I was hoping not to have the user have to run the dotnetfx.exe redistributable separately before they could install the .NET application I have written.
When I compile a deployment project I get the warning: "This setup does not contain the .NET Framework which must be installed on the target machine by running dotnetfx.exe before this setup will install. You can find dotnetfx.exe on the Visual Studio .NET 'Windows Components Update' media. Dotnetfx can be redistributed with your setup."
Does any know a way to have the dotnetfx.exe automatically run when a new .NET application is being installed? Any ideas on other options?

Thomas Scheidegger had this to say about it on the DOTNET mailing list.
MS did a last-minute change in deployment strategy!<br />

That was very helpful. Thank you. Kyle

object obj = Activator.CreateInstance(type);
arraylist.Add(obj);
generates the following compile error:
Value null was found where an instance of an object was required.
Yet this code works fine so its obvious that obj is not null...isnt it ?
object obj = Activator.CreateInstance(type);
IInterface i = (IInterface)obj;
i.InvokeAMethod();

have you done
arraylist = new System.Collections.ArrayList;?
wouldn't be the first time I've forgotten to do that

Anyone know of any good articles on printing, wrapping text and pagination, etc.?

Try www.gotdotnet.com.
They have some useful articles on GDI+. From my experience I would recommend using GraphicsUnit.Document (1/300 inch) as a scale mode. I tried using pure inches and encountered terrible roundoff errors in the GDI matrix transformations.
One issue I was not able to overcome with managed code was the printer's page offset. (0,0) is at the upper left corner in the print preview, but offset by some arbitrary amount when printing (presumably different for each printer.) This information can be found out with Win32, but seemingly not with Managed Code.

Because I also had trouble with inches and printers have default page units of GraphicsUnit.Display that is what I am using. Your recommendation seems to make more sense as it offers finer control so I think I will give it a try. I'll also check out the gotdotnet articles. Thanks.
Would you like the unmanaged code in C# to obtain the unprintable margins? I can copy and post it for you if you need it.
Thanks again, Kyle

I'm not currently working on printing, but I will probably do some in the future. So sure, if you have the Unmanaged Code handy, I can store it for future reference... 
Thank you

Here's the code:
// Reference InteropServices;
using System.Runtime.InteropServices;
// define constants for the physical offset values
private const int PHYSICALOFFSETX = 112;
private const int PHYSICALOFFSETY = 113;
// Define DLL and prototype the Win32 API method
[DllImport("gdi32")]
public static extern int GetDeviceCaps(IntPtr hdc, int cap);
// get the device context handle from the graphic object that is being printed
// call GetDeviceCaps to return the offsets
// release the handle to the device context
int unprintableleft, unprintabletop;
IntPtr hdc;
hdc = e.Graphics.GetHdc();
unprintableleft = GetDeviceCaps(hdc,PHYSICALOFFSETX);
unprintabletop = GetDeviceCaps(hdc,PHYSICALOFFSETY);
e.Graphics.ReleaseHdc(hdc);
MessageBox.Show("Unprintable: " + unprintableleft + " " + unprintabletop);

Does anyone know what all the lag is about when I run my C# console apps? It just seems to take ages before it actually start the programs. Is there anything I can do to minimise it?
Thanks in advance

What you're experiencing is the JIT taking place. To get rid of it you can run ngen.exe on your executable to pre-JIT it. I think to run ngen you might have to sign your exe. sn -k keyfile.snk creates your keyfile, the docs tell how to get it signed (I'm not at my PC right now otherwise i could give you the code for it )

Thanks matey, ngen ran without signing the exe. And now my app runs immediately. I think all this stuff should go into an FAQ somewhere. I wonder how many other people are puzzled by the same stuff.
Thanks again, you're a great help

Hi,
When I call the Directory.GetFiles() funcion, it returns an unsorted string array.
I would write a sorting algo, but if theres a class that can sort a string array can someone let me know.
cheers

You can use the static method System.Array.Sort(). This method has overloads for sorting an array in place, for customizing the sort order (non-case sensitive, etc.), or for just sorting sections of an array. The sorting algorithm employed is QuickSort.

Is it possible to create a toolband with C# similar to http://www.codeproject.com/useritems/toolband.asp
|
|
|
|

argh, can you define template classes in c#???? Or is there an alternative that Microsoft would prefer you to use?

No , you can't
With luck , next c# version will support generic programming, until then ...
Cheers,

Templates don't exist in C#, this is coming in Version 2.
There is a "trick" that'll help you get by until then.
using System;
using T = System.Int32;
namespace Test
{
class Testing
{
public Testing()
{
Console.Writeline(typeof(T).ToString());
}
}

Thanks for the response, I wanted to port a generic tree class over to C# but looks like I can't for the minute, or maybe I can. What if the class took a type of Object?
class Testing
{
public Testing(Object arg)
{
m_Object = arg;
}
Object m_Object;
}
I'm very new to C#, but would this work? Also when is version 2 out???
Thanks again

That would work, but you would have lots of casting to do (Object could be called the equivalent of void* in C). This is generally the reason that the technique I mentioned came up; while you'll have a specific class for each type of tree; you'll eliminate all casting.

Not for a while, version 1.0 came out a week ago today My guess would be at least a year before version 2.0 comes out.

No, you can't.
The next version of the CLR will support template classes, and so will be available to all languages that want to support it, not just c#
