There is an excellent WebBrowser wrapper control done in C# that gives you much greater control over the web browser--one such feature is the ability to generate a thumbnail for the current page:

hi everyone.
when you select the day, month or year in the DateTimepicker control (i.e. 08/26/2008 ) suppose here i have selected the year,
when i click the Up Arrow key it will increment the year automatically but how to do that by pressing any other key.

So what?
This is annoying and rude. You have the same post on this page.

Have you ever hear of events...Fire a event when some key is pressed. On that event do whatever you want to do.

 Is it possible to detect the insertion and removal of Plug and play devices (for example : keyboard , mouse etc) while the computer is still ON. We wanted to do the above in C#. We tried a couple of WMI classes like win32_Keyboard class, but after manually removing the Keyboard, there was no change in the Property "status" of win32_Keyboard. it showed that the status was OK.
We also tried a piece of code which uses win32_DeviceChangeEvent but that also doesnot seem to work for plug and play devices.
Plaese can u suggest some Solution to this problem.,
thanks in advance

Hello
VS 2008
I have a resource file called Form1.fr-FR.resx which has been added to my project when I set the local and language of the form.
In my Form1.fr-FR.resx I have button1.Text, button2.Text. I have set the culture to fr-FR so when the form starts its displays the french language in the buttons.
However, I would like to include some string of my own in this file. I have added strName, strAddress as I want to display these in a message box. However, when I add more control to the form the string I have added get deleted. When I open the Form1.fr-FR.resx using edit plus the string are there. However, when I try and display them, I just get a blank.
Is there some reason that the strings don't persist in the resource file?
Some code that I am using:
Dim rm As New ResourceManager("LanCulture.Form1", Me.[GetType]().Assembly) <br />
Console.WriteLine(rm.GetString("strName", Thread.CurrentThread.CurrentUICulture))
Many thanks for any advice on this,

Hi
I've made a graphic simulation with a timer. But now I want to stop the simulation (but not disappear) only freeze the simulation.
I've already tried to use a do-while-loop but then the application crashes.
I've also tried to use a if-loop and in the loop set the length (that the application have to drawn) to zero but it doesn't freeze.
I've also tried to use in a if-loop, to call another function which doesn't do anything but this doesn't freeze the application.
Also I did this in a do-while-loop but then it crashes.
Does someone knows an answer and perhaps knows an example that I can understand what you're trying to say.
PS: The simulation is shown in a pictureBox

Graphic simulations often depend on calculations done in an Update loop based on the time that elapsed since the last frame. If you set the elapsed time in your update loop to zero (i.e.: "no time elapsed since the last frame"), you can bring your simulation to a halt.
Another possibility would be to set a flag bool paused = true and stop any updates whenever this flag is true.

Thank you for your reply. Is there also an oposit of Update()? Something like .Pause()? I've tried somethings out but they aren't right.

Those methods handle completely different functions then what you may thinking. Update() or Invalidate() are used to refresh the entire form based on the information contained in the OnPaint event. Their is no way to pause the OnPaint event unless you write your own graphic logic. One of my articles Basics of Falling Blocks in VB2005[^] has been able help some people understand how the painting system works in WinForms as well as how it should be thought of.

1. With a System.Timers.Timer just use the Stop() method to stop the timer.
2. With a System.Threading.Timer, just don't use this timer (why? read documentation). Replace with a System.Timers.Timer
3. For good performance forget timers. Force rendering into app's main loop (as Greeeg mentioned)

As the others suggested, the answer is to stop the actual simulation from taking place by means of something like an internal variable or a timer setting. Simply freezing the application will cause Windows to think it has hung, and which will display the unresponsive program dialog (which I am guessing is what you are calling "crashing"). It will also not allow you to unfreeze it again later.
You might also look into performing the simulation on a separate thread (though remember you will still have to update the picturebox on the main thread), because then you will just be able to pause and resume the simulation thread at will, and without chewing up CPU cycles in an infinite loop.

But how can I do this in this code?
[code]
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
// opvragen van de burst die momenteel gedaan is
// dit kan via een methode in de Controller te steken
// die controlleerd welke knop (FCFS-SJF) ingedrukt werd
// in deze klasse wordt er dan gekeken naar de eindeburst
// Dat moet dan doorgestuurd worden naar hier.
Graphics g = e.Graphics;
String algoritme = cmbSchedule.SelectedItem.ToString();
int burstlengte = 0;
switch (algoritme)
{
case "FCFS": //burstlengte = Controller.GetInstance(ProcessList).Simulatie(ProcessList[0].lijstvanBursts[0]);
burstlengte = Controller.GetInstance(ProcessList).Hoeveelburst(ProcessList[0].lijstvanBursts[0].Lengte);
foreach (Proces p in ProcessList)
{
foreach (Burst b in p.lijstvanBursts)
{
if (Controller.GetInstance(ProcessList).Teller > p.PAankomst + b.Lengte)
{
// No simulation anymore
//burstlengte = 0;
//pictureBox1.Update();
}
//do
//{
// eind();
//} while (Controller.GetInstance(ProcessList).Teller > (p.PAankomst + b.Lengte) || Controller.GetInstance(ProcessList).Teller == (p.PAankomst + b.Lengte));
}
}
break;
case "SJF": //burstlengte = SJF.getInstance().GeordendeLijst[0].lijstvanBursts[0].Lengte;
//burstlengte = Controller.GetInstance(ProcessList).Hoeveelburst(SJF.getInstance().GeordendeLijst[0].lijstvanBursts[0].Lengte);
break;
}
// Laat de simulatie niet verder gaan als de burst gedaan is
//if (Controller.GetInstance(ProcessList).Teller > burstlengte + ProcessList[0].PAankomst)
//{
// burstlengte = 0;
//}
//int burstlengte = Controller.GetInstance(ProcessList).Simulatie(ProcessList[0].lijstvanBursts[0]);
g.SmoothingMode = SmoothingMode.AntiAlias;
Rectangle rect = new Rectangle(20, 20, burstlengte , 100);
Pen redPen = new Pen(Color.Red, 3);
g.FillRectangle(Brushes.Red, 25, 20, burstlengte , 100);
//Graphics g = e.Graphics;
//foreach (Proces p1 in lbProcessName.Items)
//{
// foreach (Burst b in p1.lijstvanBursts)
// {
// int burstlengte = Controller.GetInstance(ProcesList).Simulatie(b);
// g.SmoothingMode = SmoothingMode.AntiAlias;
// Rectangle rect = new Rectangle(20, 20, burstlengte * 2, 100);
// Pen redPen = new Pen(Color.Red, 3);
// g.FillRectangle(Brushes.Red, 25, 20, burstlengte * 2, 100);
// }
//}
}
private void eind()
{ }

First of all, move all of that outside of PictureBox.Paint and into a separate thread that modifies a shared (synchronized) bitmap image. Then run the above and either send events to the main thread to update the picture box with the current state of the bitmap at various intervals, or do this on a timer. Just be sure to use lock() before accessing the shared bitmap on either thread.
In PictureBox.Paint just draw the shared bitmap to the PictureBox.
Now when you pause the simulation, the picturebox should no longer receive signals to update, or if you put it on a separate timer, you should also pause that timer when you pause the simulation.
