do you mean something similar to:
int i;
byte[] s ={ 10, 20 };
int result=0;
for (i = 0; i <= 1; i++)
result += s[i];
though inelegant, I see no error in the above.
On the other hand, your code, ss it stands, doesn't even compile.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Yes, I mean something like this
int i;
byte[] s ={ 10, 20 };
int result=0;
for (i = 0; i <= 1; i++)
result += s[i];

Well it works fine on my system and since you have provided no inputs and no output I can only guess what is happening on yours.
Should I turn ON my Code Project Mind Reader Unit?

Hy there, I have a problem. i want to see how winforms made the ResourcePickerDialog (the one that appears when you set an Image at design-time). I found out that the class is in the assembly Microsoft.VisualStudio.Windows.Forms, but i can't seem to find the assembly anywhere, except GAC.
Does anyone know how can I disassemble an assembly installed there? I have reflector and ildasm, but they can't open assemblies from GAC.
Thanks very much.

hi
i have a panel and timer in my form, in timer.tick event handler, i want to draw a circle and increase pos.X in every timer interval, but when i run app and start animation, it has a flicker and not smoothing animation, also in constructor of my form, i write this code :
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true);
and set Form.DoubleBuffered to true, but still my problem was not solve, how to remove flicker correctly ?
here is all of my code :
int lastX;<br />
int lastY;<br />
bool reverse = false;<br />
Pen pen = new Pen(Brushes.Red, 2);<br />
<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true);<br />
} <br />
<br />
private void button1_Click(object sender, EventArgs e)<br />
{ <br />
this.timer1.Start();<br />
}<br />
<br />
private void Paint(Graphics g,int x,int y)<br />
{<br />
g.Clear(Color.White);<br />
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;<br />
g.DrawEllipse(this.pen, new Rectangle(x, y, 100, 100));<br />
}<br />
<br />
private void timer1_Tick(object sender, EventArgs e)<br />
{<br />
if (!this.reverse)<br />
{<br />
if ((this.lastX + 102) <= this.panel1.Width)<br />
{<br />
this.lastX += 2;<br />
}<br />
else<br />
{<br />
this.reverse = true;<br />
}<br />
}<br />
else<br />
{<br />
if (this.lastX >= 0)<br />
{<br />
this.lastX -= 2;<br />
}<br />
else<br />
{<br />
this.reverse = false;<br />
}<br />
}<br />
this.Paint(this.panel1.CreateGraphics(), this.lastX, this.lastY);<br />
}
thanks

You should really only draw in the OnPaint event (or override), so if you want to redraw the circle then you need to have it drawn in OnPaint and call this.Invalidate(); to update the screen.

i modify my code as follow :
public partial class Form1 : Form<br />
{<br />
int lastX;<br />
int lastY;<br />
bool reverse = false;<br />
Pen pen = new Pen(Brushes.Red, 2);<br />
<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true);<br />
} <br />
<br />
private void panel1_Paint(object sender, PaintEventArgs e)<br />
{<br />
this.timer1.Start();<br />
this.panel1.Invalidate();<br />
}<br />
<br />
private void Paint(Graphics g,int x,int y)<br />
{<br />
g.Clear(Color.White);<br />
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;<br />
g.DrawEllipse(this.pen, new Rectangle(x, y, 100, 100));<br />
this.panel1.Invalidate();<br />
}<br />
<br />
private void timer1_Tick(object sender, EventArgs e)<br />
{<br />
if (!this.reverse)<br />
{<br />
if ((this.lastX + 102) <= this.panel1.Width)<br />
{<br />
this.lastX += 2;<br />
}<br />
else<br />
{<br />
this.reverse = true;<br />
}<br />
}<br />
else<br />
{<br />
if (this.lastX >= 0)<br />
{<br />
this.lastX -= 2;<br />
}<br />
else<br />
{<br />
this.reverse = false;<br />
}<br />
}<br />
this.Paint(this.panel1.CreateGraphics(), this.lastX, this.lastY);<br />
} <br />
}
but result was very bad and my problem was not solve, can u wite your suggestion code ?
thanks

You need to put this.timer1.Start() somewhere else (like, wherever you had it before) and move this.panel1.Invalidate() into your timer.
Then, call your draw method from within the onPaint event:
private void panel1_Paint(object sender, PaintEventArgs e)
{
this.Paint(e.Graphics, this.lastX, this.lastY);
}
Don't forget to remove this.Paint(...) from your timer.
int lastX;
int lastY;
bool reverse = false;
Pen pen = new Pen(Brushes.Red, 2);
public Form1()
{
InitializeComponent();
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true);
this.timer1.Start();
}
private void panel1_Paint(object sender, PaintEventArgs e)
{
this.Paint(e.Graphics, this.lastX, this.lastY);
}
private void Paint(Graphics g,int x,int y)
{
g.Clear(Color.White);
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;
g.DrawEllipse(this.pen, new Rectangle(x, y, 100, 100));
this.panel1.Invalidate();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (!this.reverse)
{
if ((this.lastX + 102) <= this.panel1.Width)
{
this.lastX += 2;
}
else
{
this.reverse = true;
}
}
else
{
if (this.lastX >= 0)
{
this.lastX -= 2;
}
else
{
this.reverse = false;
}
}
this.panel1.Invalidate();
}

Thanks again
but do u test your code ?
i run this code, but it's get very bad result :
public partial class Form1 : Form<br />
{<br />
int lastX; int lastY; <br />
bool reverse = false; <br />
Pen pen = new Pen(Brushes.Red, 2); <br />
<br />
public Form1() <br />
{ <br />
InitializeComponent(); <br />
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true); this.timer1.Start();<br />
} <br />
<br />
private void panel1_Paint(object sender, PaintEventArgs e) <br />
{ <br />
this.Paint(e.Graphics, this.lastX, this.lastY);<br />
}<br />
<br />
private void Paint(Graphics g, int x, int y) <br />
{ <br />
g.Clear(Color.White); <br />
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed; <br />
g.DrawEllipse(this.pen, new Rectangle(x, y, 100, 100)); <br />
this.panel1.Invalidate(); <br />
}<br />
<br />
private void timer1_Tick(object sender, EventArgs e) <br />
{ <br />
if (!this.reverse) <br />

if ((this.lastX + 102) <= this.panel1.Width) <br />
{ <br />
this.lastX += 2;<br />
} <br />
else <br />
{ <br />
this.reverse = true;<br />
} <br />
} <br />
else <br />
{ <br />

{ <br />
this.lastX -= 2; <br />

else <br />
{ <br />
this.reverse = false;<br />
} <br />
} this.panel1.Invalidate();<br />

Haha, ok, windows timers lose any kind of accuracy at about 1/18th of a second, so setting it to one isn't much better than setting it to 40.
Go download the demo code off of my article here[^] it has some simple code for a MultimediaTimer, which can be accurate to the millisecond (though you probably want to set it to about 16, which is about 60fps).
I recommend reading my couple of articles and stealing the code to make your shape move, and i'm not just advertising, i think you will find them usefull (the code anyway). First article here[^]

Thanks again SK Genius
but when i set Timer.Interval to 100, it's still get me wrong result.

I think we may have left this.panel1.Invalidate(); in the Paint(graphics, int, int); method, take that out and it should be much better, it still flickered though.
Oh, i got it to stop flickering by taking out g.Clear(Color.White); just set the panels backcolor to white instead.

yes SK Genius
when i remove this.panel1.Invalidate(); from Paint(graphics, int, int); it is much better, but still a little flicker, is there anyway to remove this little flicker ?

If the files are zipped through third party library then u have to use the same to unzip...
check the following link ...it shows the compression using windows shell API and C#

The command format for extracting files is:
winzip32 -e [options] filename[.zip] folder
where -e is required.
options:
-o for "Overwrite existing files without prompting"
This along with System.Diagnostic.Process class might help.
