System.Windows.Forms.Application provides static function. I need to get 'this' instance of the Application, just like AfxGetApp provided in MFC, or the Application instance in VB.
Any ideas?

Where is the Application Object?

Hey !

In VB we can easily access the Application object. This is also available in MFC as AfxGetApp().
What is the C# .NET equivalent?

Sized form for pocket pc

Hello, I want to make a dialog with a given size for pocket pc.
For doing that I have derived my class from System.Windows.Forms.Form and I have set the property Size for my form with my prefered size. But the result is not what I have expected.
Do you know what can be the solution for my problem?

public class SelectionTool : System.Windows.Forms.Form
{

public SelectionTool(String title, String lblText){
InitializeComponent();

}

private void InitializeComponent()
{
//that line of code doesn't set the size for my form
this.Size = new Size(20,40);

.....

this.ShowDialog();
}

}

Your best bet is probably to write a DLL in C that performs any low-level input, then use the Platform Invoke feature to access that.

You can also P/Invoke _getch directly.

[DllImport("msvcr71.dll", CallingConvention = CallingConvention.Cdecl)]
static extern int _getwch();

[STAThread]
static void Main(string[] args)
{
   Console.WriteLine( "Press any key to continue" );
   Console.Out.Flush();
 
   char ch = (char) _getwch();
 
   Console.WriteLine( "You pressed {0}", ch );
}

You must call Flush, because the Console class performs buffering on the stream. Failing to do so can cause the prompt to be displayed after _getwch executes, not before.

Note that I used the wide-character version, _getwch, because the CLR uses wide characters internally.

What about Console.Read() ? Doesn't that work?

Actually I don't think you did... I'm sure he just wants to read some character from the console...

Playing a simple sound with C#

Hi,

I would enjoy playing a short custom sound with C# (like a beep) when the mouse moves over a button for example, like Ineternet Explorer does.
Would anybody help me ? Thanks.

Use managed DirectX or use P/Invoke to call the play sound method in the Win32 API.

How to configure an Ethernet connection?

Hi all.

I'm trying to set the IP of my NIC's. I have found nice examples showing how to get the IP through the WMI, but how can I set it?

All hints are appreciated.

As far as I know, you can't without going through the natice API, and configuring it with no DHCP, and then setting a static ip address.

Thanks for the answer, Giles.

That was a little discouraging, but I'll see what I can do about it.

If anyone out there has a piece of code for this - please post if for me.

I'm pretty sure I had a friend do it in C++ once using WMI (NetworkConfiguration class). If you can do it in C++, I would assume you could wrap it in C#.

Yes and no.

If your application contains no GUI then you can most likely compile the appliaction for Mac OS-X. However you'll need a different version of the .NET Framework to compile your code. Check out www.go-mono.com[^]

If your application contains any GUI code then it will be much less likely to work with Mono

Probably 2 choices , Mono by Ximian, or Rotor, which is a shared source implementation by Microsoft that compiles on Windows XP and Free/Open/Net BSD Unix's.

Mono on Linux makes use of Wine to do the GUI bit, though I have no idea about Rotor.

System.Windows.Forms is not included in Rotor. You can get Rotor from http://www.microsoft.com/net/sscli/[^].

The application created with Portable .NET runs under OSX, but the compiler runs only under Linux. Is it true?
