/platform:<string>
Limit which platforms this code can run on: x86, Itanium, x64, or anycpu. The default is anycpu.
</string>
It has nothing to do with optimization.
As usual, MSDN is wrong.

nice one:[^]
- the title is "How to: Optimize an Application for a Specific CPU Type"
- for C# the page says "Choose a CPU type from the Platform target list. The options are ..."
- and Guffa rightfully says "The IL code in your assembly isn't specific to any processor at all"
So the page not only fails to tell you how to decide on the right platform, it also leads you to believe that by choosing you would be optimizing the application. The whole page is crap

Yes, very confusing. It even got me and I should have known better.

Wrong. Selecting x64 does NOT give the best performance. This only forces the code to work on a 64-bit processor using the 64-bit .NET Framework. This also give you coding options that are specific to 64-bit. Performance really has nothing to do with it.

Thank you, everyone, for your insight on this issue.
Can I ask you, now, how I should go about optimizing my code for x64 processors? Any links you would recommend would be much appreciated.
Many thanks,
Morten

Hello guys,
As I said in the subject line, the goal is to deploy a console application to another machine without Visual studio 2008 installed on that machine. It does have 2005 installed on it though.
Questions:
1- Do I need to install the Framework 3.5 on this machine for the console app to work?
2- I'm not sure what steps should be taken to accomplish this deployment (provided that I install the framework). In other words the Bin directory of this folder contains consoleApp.vsHost.exe.manifest (type: manifest file), consoleApp.vsHost (type: Application), ConsoleApp (type: Application).
3- Should I just copy over these files and a few other DLLs that are being referenced from this console application over to the other machine and be able to run the executible from there?
4- when I right click, and look at the properties of the console application project, i see quite a few options (in VS 2008) Is the publish option relavent to this deployment? Especially the publish location and install Mode and settings options?
Thank you all so much in advance for your help 
Tina

1 - Yes, if it uses 3.5
2 - See 3
3 - You can, and I do it that way, but it depends on other factors
4 - That's another way to do it, which maybe I should do, but don't

Just Take all files of Bin folder to destination machine

You do not require source files on client computer

in my app i've apicture box and when clicked on that i want to show that this picturebox is clicked by changing the color of the border, how can i do it?
|
|

Sadly enough, this control does not expose a border color, even for classes inheriting from it. Your only choice is to draw it yourself, you can for example create a class that inherits from the PictureBox and override the OnClick (or just handle it) to paint the border, it can be something like that:
public class PictureBoxEx
: PictureBox
{
protected override void OnClick(EventArgs e)
{
base.OnClick(e);
Pen pen = new Pen(Color.Red);
this.CreateGraphics().DrawRectangle(pen, base.ClientRectangle);
}
}
This code is not entirely correct, the base.ClientRectangle rectangle is inside the real border but I'll leave it to you to compute the correct coordinates.
The disadvantage of this approach is that it is not done in the "Paint event" of the control, so any redraw (caused if you ALT-TAB or just move something over it, like another window) will cause the control to redraw itself and your border will disappear. I don't know what you really want, if the idea is that it should STAY colored after the click, then override the OnClick and trigger the OnPaint after having set a boolean or so to indicate the clicked state; in the OnPaint, check this boolean and draw the border if the "clicked" state check is positive.
Another disadvantage, but this was really quick code to show the idea, is that I am using a Graphics object that I create myself. In the OnPaint handler, you should use the provided Graphics object from the eventArgs, otherwise you loose Double-Buffering.

So you're not really. You actually want someone else to do it for you.

I think the easiest way to do this is go to the keyboard. Press the Button with the "Window" on it + "L". That should lock your Hard Drive/PC.
Good luck.

As i hav seen all previous reply's to "kabhi bhi is tarah se kahabhi kaise bhi sawal mat poocho " but i m interested to give the answer here is solution.
Actually locking is not done by the code. What u hav to do is, first understand the Windows Registry basics. Once u hav understood the basic about windows registry u can lock any drive on hard disk.
There is key in windows registry(refer it from documentations ). I m not sure but it contais 32 bits.
the bit is either 1 or 0
Suppose u want ot lock c: then simply change 1 to 0 at appropriate position.
11111111111111111111111111111111 change it to
11011111111111111111111111111111
I hav written same program that changes this registry key.

to lock C: drive the DWORD value would be 10bin(2dec) not 11011111111111111111111111111111bin.
Following values lock the drive typed at right side. (1a : 1 locks A: drive, and 12cd: 12dec(1100bin) locks C: and D: drives.
1a
2b
3ab
4c
