Hi All,
When a windows service is installed, the app.config file is not copied to the installed location, but I have some data in that.
Can any one tell me how to get the app.config file in the installed location of windows service.
Thanks a lot in advance.
Best Regards,
M. J. Jaya Chitra

How are you installing your Windows service?
Using the Visual Studio Setup project, the app.config is considered part of the "Primary Output" of the WinForm/Console application project.

I have 10 different classes in an application. I need to access a constant (int value = 125;) in all ten classes.
Which is better way of following two options?
1. Declaring int value = 125; in all classes
or
2. creating static class
public static class Constants
{
public static int value = 125;
}
using it as Constants.value in all classes.
Any other best option?
Thank you in advance..

If you put it in a static class, this is accessible to all other classes, not just your ten classes. Putting it in each class is a maintenance nightmare - if you add an 11th class, you have to remember to add the int. If the int changes, you have to change it in all places.
Do the classes all derive from a base class? If so, put it there and make it protected.

A static variable in a class is the best option (or similar solutions).
Declaring the same value in several places largely defeats the purpose of declaring it at all.
If you use a constant, the value will be inlined when compiling, so if you change the value you have to recompile all code to get the value to change everywhere. If you have a static variable, all classes will always read from the same physical variable.

Hi all,
I want to find that a user is login to a specific system(simply a computer) or it is in standby mode, using C#. Can you friends give me a clue.
Thanks, 
I appreciate your help all the time...

If it is in standby mode, isn't the screen usually blank, and if a user is logged in, won't they be sitting near the keyboard?
Are you doing this remotely? Or is your C# app running on the computer in question?

What I'm worried is that, in standby mode, is that user is login or not. Because in standby mode all users are displayed on the screen.
I appreciate your help all the time...

You could use WindowsIdentity.IsAuthenticated to determine is the current user is logged in.

Yes, I have done it in this way.
WindowsIdentity.GetCurrent().IsAuthenticated
Thing is that I want to check it is ok, in standby mode.
I appreciate your help all the time...

In my datagridviewCtrl, comtains one checkboxcolumn if i check it and close the window
and if checking status of the same checkboxcolumn inside closingform event it's formated value is false which should be true .
same.
This is happening with only close event same with closinfForm event.
Is there any function available in C# like "UpdataData(false)" which is available in VC++.
I tried with Refreash() and Invalidate() it not working.

Your question is horribly unclear and this is the wrong forum for VC++ questions. If this is truly realted to C# then please try to rephrase your question and give more details.
Take care,
Tom

I'm still not 100% sure what you are asking. But I think you are looking for the EndEdit[^] method. If the cell you are currently editing is not committed to the underlying data source, then you can use EndEdit to commit the change.

I reckon it's time to put some effort into this and be a little bit more specific with your problem.

I would like to draw a line from one point on a circle to another point on the circle. I tried getting the points as follows, but the PathData gets only 13 points-not enough.
If possible, the circle should be divided into 360 degrees and I would like to draw a line from any degree to any degree. Thanks for any help or tips!!!
private void Form1_Paint(object sender, PaintEventArgs e)<br />
{<br />
Graphics g = this.CreateGraphics();<br />
GraphicsPath path = new GraphicsPath();<br />
path.AddEllipse(200, 200, 500, 100);<br />
g.DrawPath(new Pen(Brushes.AliceBlue), path);<br />
PathData pd = path.PathData;<br />
<br />
}

Just calculate the coordinates, then you have a resolution that is ever far better than one degree.

You would not have an C# example? The wiki example is in JavaScript and I don't know what "points.push(new OpenLayers.Geometry.Point(X, Y));" does. Thanks for your help!

It adds an item to the array. As you only need one point on the circle you don't need to loop through the angles, thus you need no array.

Hi,
After reading Chris Maunder’s message, I am a little bit afraid of writing my message….
Anyway, I will make an effort to ask my message courteously.
I used ‘FileSystemWatcher’ to read files from a directory path, what I had to do was to ReadAllBytes of the file had been created, to display the result in some way, and delete the file.
I had a problem that had been discussed in many forums – how to know if the file’s create is completed,
All brought to Microsoft forum: http://www.thescripts.com/forum/post1712613-10.html, I used the advice written there:
while(true)
{
Try to open the file for reading
Break if succeeded
Catch an exception and sleep(1000) – if the file is in use by another process.
}
That worked as well.
Now, my problem is when I send to the directory load of files at a short time – the FileStreamWatcher recognizes the first files – but stops there and doesn’t continue to read the all the others.
I have no way to debug it line by line, because when I put a breakpoint there, passes enough time to read the next file… and the point is that the time between the create and delete is too short.
Please pass the answer also to my direct email: sara.sekler@verint.com
I hope my question is clear and brief enough ….
Many thanks,
Sarah
