I might, I might not. The name doesn't ring a bell, but I'm no good at pattern names. Show the world.
BTW: I did come up with some new patterns, the most famous one I called "upside-down programming"
which is a kind of extreme instruction scheduling at the level of very simple statements (say elementary C). Excellent for video processing and other very repetitive stuff that tends to be memory/cache latency bound.

(answering just to test my knowledge) I believe (and hope) that Mike means changing this;
for (int x = 0; x <= 50; x++)
{
DoMethod1();
DoMethod2();
}
To something like this;
for (int x = 0; x <= 50; x++)
{
DoMethod1();
}
for (int y = 0; y <= 50; y++)
{
DoMethod2();
}
..which is counter-intuitive (for me at least), as I'm doing the loop twice in the latter example using more resources. The latter example would be easier to maintain, as it's more readable.

OK thanks, I see. Yes I have been using it.
As far as performance goes, two comments:
1. "split loop pattern" makes sense if the data sets used by both halves are distinct and "locality of reference" is relevant, then the split reduces the load on the cache+memory system
2. the opposite ("merged loop pattern"?) makes much sense when both halves work on the same large data set (exceeding cache size), so merging makes the code walk the data just once. I happen to have the draft of an article (on finding primes) clearly demonstrating this. Due next month.

Does anyone have any idea about it.? Please Help ...

It looks like you're trying to use a Windows Forms control in a Web Forms app. Is this correct?? This question actually belongs in the ASP.NET forum.
Well, since the code is running in the browser (not on the server side), the browser will run the code in a heavily restricted sandbox. There are many, many things that the code will not be able to do unless the browser security is turned way down, and the .NET Framework on the machine is told to trust that assembly.
And since I've never done this, my experience is quite limited.

This is my given code below ,it has two buttons ADD and REMOVE and TABCONTROL .ADD button adds the tabpages.
REMOVE button removes the tabpages in the order the latest clicked tabpages .That is the order of
opening(clicking) the tabpages is preserved so that while removing the latest tabpage opened will be
removed first.Now, if u execute the program below, u will understand the functionality.
public partial class Form1 : Form
{
private static int pageNumber = 4;
List<tabpage> _cache = new List<tabpage>();
public Form1()
{
InitializeComponent();
this.tabControl1.Selected += new TabControlEventHandler(tabControl1_Selected);
}
void tabControl1_Selected(object sender, TabControlEventArgs e)
{
if (e.TabPage != null)
{
if (_cache.Contains(e.TabPage))
{
_cache.Remove(e.TabPage);
}
_cache.Add(e.TabPage);
}
}
private void button1_Click(object sender, EventArgs e)
{
TabPage page = new TabPage("TabPage" + pageNumber.ToString());
tabControl1.TabPages.Add(page);
this.tabControl1.SelectedTab = page;
pageNumber++;
}
private void button2_Click(object sender, EventArgs e)
{
if (_cache.Count > 0)
{
this.tabControl1.Selected -= new TabControlEventHandler(tabControl1_Selected);
this.tabControl1.TabPages.Remove(_cache[_cache.Count - 1]);
this.tabControl1.Selected += new TabControlEventHandler(tabControl1_Selected);
_cache.RemoveAt(_cache.Count - 1);
}
if (_cache.Count > 0)
{
this.tabControl1.SelectedTab = _cache[_cache.Count - 1];
}
}
Now, my given requirement is i need to set some color to each and every tabpage
added, i need to implment the color property in ADD button.I googled a lot but i couldnt implement it according to my program.So can u pls
send me any sample according to my program so that i could implement it.
Thanks in advance

I won't do that, but I will suggest that you research OwnerDraw property value.

Hi,
I would like to find a report designer tool which permits the end user to create a report based on some predefined elements created by the application I want to build. So, the basic idea would be to extend an already existing tool to achieve this kind of functionality.
So, if any of you have some thoughts or recommendation to what kind of software could I use, please give me some hints. Thanks in advance.

to add the tabpages and REMOVE button to remove the tabpages in the order the latestly opened tabpage.That
is,the order of opening(clicking) the tabpages is preserved so,that while removing the tabpage last opened gets
removed first.If u exceute my program below will understand the functionality.
public partial class Form1 : Form
{
private static int pageNumber = 4;
List<tabpage> _cache = new List<tabpage>();
public Form1()
{
InitializeComponent();
this.tabControl1.Selected += new TabControlEventHandler(tabControl1_Selected);
}
void tabControl1_Selected(object sender, TabControlEventArgs e)
{
if (e.TabPage != null)
{
if (_cache.Contains(e.TabPage))
{
_cache.Remove(e.TabPage);
}
_cache.Add(e.TabPage);
}
}
private void button1_Click_1(object sender, EventArgs e)
{
TabPage page = new TabPage("TabPage" + pageNumber.ToString());
tabControl1.TabPages.Add(page);
this.tabControl1.SelectedTab = page;
pageNumber++;
}
private void button2_Click_1(object sender, EventArgs e)
{
if (_cache.Count > 0)
{
this.tabControl1.Selected -= new TabControlEventHandler(tabControl1_Selected);
this.tabControl1.TabPages.Remove(_cache[_cache.Count - 1]);
this.tabControl1.Selected += new TabControlEventHandler(tabControl1_Selected);
_cache.RemoveAt(_cache.Count - 1);
}
if (_cache.Count > 0)
{
this.tabControl1.SelectedTab = _cache[_cache.Count - 1];
}
}
Now,my problem is while removing the tabpages that is,when i click on the REMOVE button after TWO
seconds the tabpages should get removed,that is with the delay of two seconds the tabpage should get removed.That is i need to set the time in the REMOVE Button .Can,u pls help me out unable to fix it can u send me sample according to my program.
Thanks in advance.

As my subject says, I am trying to create a border function like excel in datagridview. I have been googling for few days, and it looks like there is no easy answer to set border color for selected cells. If anybody has any clue on how to do this, it will be much appreciated. Thank you very much!
Note: I have successfully created bold function and (modified with the color picker found from this site) color picker for backcolor and forecolor with saving the setting in an xml file. If anyone needs it, please let me know.

I think that if you research the CellPainting event, you might get some ideas on how to do this.
