I've never needed to do this on Color so I gave it a try.
Console.WriteLine(sizeof(Color)); interestingly produces the following error:
'System.Drawing.Color' does not have a predefined size, therefore sizeof can only be used in an unsafe context.
Console.WriteLine(System.Runtime.InteropServices.Marshal.SizeOf(typeof(Color))); returns 24.

Are you running a 64-bit Windows version?

No, that was Vista 32bit.

So today we learned one drop of color paint is much bigger than one pixel.

Hi,
Looking at it with both the Reflector tool and some reglection code, the conclusion seems to be Color struct occupies 24 bytes, holding:
string name;
long value;
short knownColor;
short state;
[CLARIFIED]
on Win64, there are 8+8+2+2 meaningful bytes, struct alignment rounds it up to 24 and all is fine;
on Win32, if they had chosen a different order of the fields, the 4+8+2+2 bytes would have fitted into 16 bytes of memory.
[/CLARIFIED]

why string if its pointer. Pointers are suppose to be IntPtr or long.

On the functional level, it is a string. However strings are reference types, so what is actually sitting inside the struct and taking up some bytes, is just a 32 or 64-bit pointer/reference to the actual string. We ancients, with a pre-.NET background, call that a pointer.
When you need to pass a reference of something to the native world, the correct way is by using an IntPtr; a long would be wrong, and so would be an int. IntPtr adapts itself automatically to the Win32/Win64 situation at hand. Unfortunately the majority of P/Invoke examples on the web are still using int for passing pointers, and so they are plain wrong.

but struct is not holding string...its holding pointer numeric value. If I'm not wrong then string size is depend on character length ?

The data (characters) of the string are not relevant here, the struct only has something that knows where the data is, call it a reference, a pointer, an indirection, or whatever you like; it needs 4 or 8 bytes to do that depending on the kind of Windows it is built for.

I writing some application that have reference of Microsoft office outlook.
My application can work with office 2007 or office 2003.
When i work with office 2007 all work fine - and i don't have any problem to control the outlook.
But with office 2003 i cant control the outlook even if i install the interop assembly of office 2003.
I think that the problem is in the loading Interop assembly - because i compiled the setup file with office 2007.
Someone can help ?
I don't know how to solve this problem.

How to associate event handler with the Idle event in c#?
thanks

public static event EventHandler Idle
private void Application_Idle(Object sender, EventArgs e)

MessageBox.Show("You are in the Application.Idle event.");

I tried this. But with this how will it attach the Application_Idle to Applications Idle processing?
thanks

Hello,
I am using table layout panel so my C# application UI looks better even if we change screen resolution. My all controls are docked fill in different cells of tableLayoutPanel. I am 1280 by 1024 resolution to develop UI.
If i change resolution to 800 by 600 then the size(height) of button reduces extremely and text also doesn't fit in button but the other controls like text box seems to be ok.
How do i make sure that the button size reduces according to the parent control and also button text should be visible?
Thanks in Advance.

|

Find the height and width of the button at its smallest possibly size where the text is still visible. Then write a simple script saying that it can't be smaller.
hmmm pie

Hi!
Design your layout in 800 by 600 resolution. and then move to 1280 by 1024
Thanks

Thanks all.
Designing in lower resolution works for me.

I want to create a Console Application in C#.NET 2.0
I am trying to create a class in C# that Prints an Output Hello but that class don't have Main()
I think this can be created by using keyword "static"
This is the CODE
using System;
class StaticTest
{
static void A()
{
Console.WriteLine("Hello!");
}
}
THANKS

One class in your project must have a Main. Main is the entry point into your application.
Any class with a Main can be the StartUp object.
The Main can return void or int.
It can either be parameterless or take a string array.
