Hey guys, I'm having a problem double buffering my control.
The control requires the UserPaint flag set to false, so I manually paint the control. Now since the control is painted over and over again I experience some flickering problems. What is the best way to create a custom like double buffer which prevents my control from flickering? The OptimizedDoubleBuffer style does not work when UserPaint is set to false.
<br />
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);<br />
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);<br />
this.SetStyle(ControlStyles.Selectable, false);<br />
this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);<br />
this.SetStyle(ControlStyles.UserPaint, false);<br />

Hi,
Does anyone know whether it is possible to write managed code that utilised the L1 and L2 cache? The reason I'm asking is because it is faster to access the L1 and L2 cache.
Thanks

The most recently used data and code are stored in the cache automatically, and only swapped out to main memory when something else needs the space. You don't need to do anything special to make this work. For computationally intensive code you want to try and keep your working set of data and the hot loop of your code small enough to fit into the cache if possible, but these days that's almost never needed unless you're doing scientific computing in which case you should probably be using C++ to begin with so you can ultimately rewrite the innermost sections of the hot loop in assembler This ofc assumes you are or have the skills of a good assembler programmer available, an average coder is probably going to be out performed by the compiler now.

Hi Dan,
Thanks for replying. I'm actually involved in high performance computing. I've read an article on whether CLI-based virtual machine is suitable for high performance computing and the conclusion is it is possible. Code becomes more efficient as JIT compiler progresses from one version to a new version. I believe Java Grande has also proven that Java is suitable for high performance computing.

kk

Has anyone got crystal to work with MySQL and VS 2005?
I've tried connecting via ODBC and everytime i touch the database expert VS encounters problems and has to close. I've had a really good search on Google and can't find any pointers as to how to get these things to work.
If anyone's got a website that might help me i'd be really grateful,
Thanks in advance,
Russell

Hi,
I want to search a specific string in .txt file and copy that string in to another file. How can i do this in C#?

Try this out:
StreamReader reader = new StreamReader("c:\\test.txt");
String line = "";
while(line != null)
{
line = reader.ReadLine();
if(line.IndexOf("is line two") != -1)
{
StreamWriter writer = new StreamWriter("c:\\testOut.txt");
writer.Write("found!");
writer.Close();
break;
}
}

By encrypting (or, to be accurate, hashing) the password that the user typed in then comparing the two MD5 hash values.

I need to start a Webbrowser and control it's behaviour afterwards (Navigate, show/hide menu...). To simply call iexplore.exe with an URL or use the WebBrowser-Control is not an option
Previous to C# I used the IWebBrowser2-Interface out of SHDocVw which worked just fine, I tried to do the same C# but every time I want to .Navigate I got a ComException with HRESULT of 0x80004005 (E_FAIL).
Anybody got an idea?
Thanks in advance

I did something of this sort with the WebBrowser control in VS 2005. But this is just a control and does not open IE in a separate window. You need to develop a windows form which has this control embedded. You can control almost all the navigation and display options of IE using the methods and properties of the control.

Please tell what the problem you are facing. We are not here to write code for you. Supply code snippet or scinario which you are facing problem.
I suggest you should try google first and see how database connection works with c# application and so on.

Your question was easy enough to understand, unfortunately it is not one that can be answered in a single post.

Everyone has to start somewhere! At least you have not shosen a ridiculously difficult first project like "I want to write a face recognistion service that interops with 2 cameras to track movement  "
Start by lookin g into ADO.NET - this provides you with database access capabilities. You could also look at DataBinding if its a windows forms app, otherwise look at ASP.NET page lifecycle to discover how to link web controls to data drawn from a database.

hey Stoumann are you a new Developer.
Have you ever heard of the ADO.Net or just did you google that how to insert people to database using C#.
So first try to google it and get the Articles there are lot of articles are there.
SO try with the articles and then if you have got any problem ie., error tell here.we will help you in solve that problem.
this is not a single step answer to tell in this regards.

Hello everybody!
Can someone tell me why the following code comes to the conclusion that using an event instead of a direct method call is about 3 times faster????
Its pretty simple, just copy it at give it a go!
------------------------------------------
public class Class1
{
event TestDelegate TestEvent;
delegate void TestDelegate(String test);
public static void Main(String[] args)
{
//Number of cycles
int n = 10000000;
Class1 c = new Class1();
//register events
c.TestEvent += c.Test;
c.TestEvent += c.Test1;
c.TestEvent += c.Test2;
Console.WriteLine("Calling event {0} times....", n);
DateTime startTime = DateTime.Now;
//Call the event n times
for (int i = 0; i < n;i++ )
{
if(c.TestEvent != null)
c.TestEvent("i = " + i);
}
DateTime stopTime = DateTime.Now;
TimeSpan duration = stopTime - startTime;
Console.WriteLine("Calling normal {0} times....", n);
startTime = DateTime.Now;
//Call the event n times
for (int i = 0; i < n; i++)
{
c.Test("i = " + i);
c.Test1("i = " + i);
c.Test2("i = " + i);
}
stopTime = DateTime.Now;
TimeSpan duration2 = stopTime - startTime;
Console.WriteLine("Event based call took: {0},{1} sec", duration.Seconds, duration.Milliseconds);
Console.WriteLine("Normal call took: {0},{1} sec", duration2.Seconds, duration2.Milliseconds);
double eventTime = duration.Seconds*1000 + duration.Milliseconds;
double normalTime = duration2.Seconds*1000 + duration2.Milliseconds;
Console.WriteLine("Normal calling is about {0} times faster.", eventTime/normalTime);
Console.ReadLine();
}
private void Test(String test)
{
//do sth
int i = 0;
int x = i * 2;
}
private void Test1(String test)
{
//do sth
int i = 0;
int x = i * 2;
}
private void Test2(String test)
{
//do sth
int i = 0;
int x = i * 2;
}
}
------------------------------------------
Thanks in advance!
