I have seen that code but I thought it was to use on your own DirectX application to save a screenshot of your own DirectX application.

Can you tell me how to use that code?

Thanks.

Timer interval not change while running the windows service in C#

Hi
I made a window service application and I used system.timers.timer class . I set timer interval from config file. I would like to fire timer as specified interval in config file. It works fine but while running the windows service I want to change timer interval in config file and timer should be fired at latest interval . When I stop the service and restart the service then timer fire as specified value in config file.

Pseudo code

private System.Timers.Timer timer2 = new System.Timers.Timer();
protected override void OnStart(string[] args)
{
// dblValue = 30000
double dblValue = Convert.ToDouble(ConfigurationManager.AppSettings.Get("Interval"));

timer2.interval = dblValue
timer2.Elapsed += new System.Timers.ElapsedEventHandler(timer2_Elapsed);
timer2.Enabled = true;

}
void timer2_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
timer2.Enabled = false;
// doing some operation

// Now I want to change the value in config file like dblValue = 60000

double dblValue = Convert.ToDouble(ConfigurationManager.AppSettings.Get("Interval"));
timer2.interval = dblValue

timer2.Enabled = true;
}

but timer always fired after 30000 milliseconds. But I want , timer should be fired after 60000 milliseconds , means latest value define in config file. Please tell me how to do this ?

Rajesh

Its because config files are only read once and then cached.

Write your own config system and read it on each cycle.

Personally, I use a database for that.

I just found this one :

http://www.bobpowell.net/embedfonts.htm[^]

But it is easier to copy the font to c:\windows\fonts. Then use it using class Font.

Hello "stancrm" Thanks for the answer but I'm steel have a problem which is when I try to play the application on an other PC I'll be obliged to do the same thing (copying the font into C:\Windows\fonts) which isn't really a good solution , is there any better idea? Sigh | :sigh:

thanks a gain Wink | ;)

If you see the "big" application, like coreldraw or adobe photoshop, they copy also custom fonts to c:\windows\fonts.
I think, it is the best solution, instead of drawing your own fonts and write lot of own codes.

Go to the location where you saved the font to and copy it into the Windows Fonts directory after scanning it for viruses etc.

Now that that's done. Inside the properties pane for the TextBox control, you should be able to open the list and see your new font.

Access Methods of a Class Directly

Matt Clarkson29-Jul-09 1:00

You can access the Exists method of System.IO.File class directly like so:

bool fooExists = System.IO.File.Exists("C:\foo.txt");

I have created a class that has a method in it that logs an exception to an XML file, such as:

namespace Matt.Clarkson
{
	using System;
	using System.IO;
	using System.Xml;
	using System.Security;
	using System.Windows;

	public class ExceptionLogging
	{
		public bool LogException(Exception ex)
		{
		[code for logging file]
		}
	{
}

I can access this fine with the following code:

Matt.Clarkson.ExceptionLogging foo = new Matt.Clarkson.ExceptionLogging();
try
{
	System.IO.Path.GetDirectoryName(">?|>FDA{}{}!@'#~¬");
}
catch (Exception ex)
{
	foo.LogException("Epic Fail", ex);
}

But I cannot do:

Matt.Clarkson.ExceptionLogging.LogException("Epic Fail", ex);

I understand why I cannot do the above line of code but how can i structure my classes/namespace so that i can use methods like in the .NET framework File.Exists example above. I have no need to create a new ExceptionLogging class as I just want the method inside.

I know that the above method could just be the constructor of the class but I am looking to understand the way to do this structure.

I would love to read a tutorial on this subject but I'm not even sure what this falls under? Sigh | :sigh:

Thanks for any help,

Regards,

Matt Clarkson

To extend the previous answer, you do not need to decvlare the class as static, only the method.

The usage rules are very simple, an object can call any static, or class, methods but class methods can only call instance methods of passed references.
An object can reference class variables; there is a single instance of a class variable shared by all of the instances.
