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.
Take care,

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

According to MSDN: The Windows operating system notifies your component of file changes in a buffer created by the FileSystemWatcher. If there are many changes in a short time, the buffer can overflow. This causes the component to lose track of changes in the directory, and it will only provide blanket notification. Increasing the size of the buffer with the InternalBufferSize property is expensive, as it comes from non-paged memory that cannot be swapped out to disk, so keep the buffer as small yet large enough to not miss any file change events. To avoid a buffer overflow, use the NotifyFilter and IncludeSubdirectories properties so you can filter out unwanted change notifications.
To keep from missing events, follow these guidelines:
Increasing the buffer size with the InternalBufferSize property can prevent missing file system change events.
Avoid watching files with long file names. Consider renaming using shorter names.
Keep your event handling code as short as possible.

with hope I've got what you meant - this is my problem:
each file name is at least 25 characters, and the business I have to do inside is actually a bit of work... and it takes time..
Do you have any other idea?
Thanks!!
Sarah

If you have to do a lot of processing I suggest you use threads for that so that the event handler exits as soon as possible.

Perhaps it doesn't mean long file name, or hard business, but it worked!!!!!!
Which internal side are you recommend to init the buffer (I multiplied it - the value before was like 8912...)?
Thanks!!!!!!!

Hi all,
I’m a C++ developer and a very beginner in both C# (.Net) and Word Programming. What my company wants next is something like this: from different texts to build a Word 2007 document and then open this in the real Word 2007 application to give the user the possibility to change the document as usual with all possibilities (Menüs, Panels, etc.). Well my problem is that the Word 2007 must be embedded in our C# - Application (WinForms).
Knows somebody a solution to do this: embed the Word 2007 application in WinForms or if better maybe in WPF? For any idea thank you in advance.
Best Regards,
Emil

I don't think you can embedd it. I do believe you can run/control it, using the Office Toolkit, or whatever they call it.

The interop stuff is pretty straightforward. Look up Microsoft.Interop.Office.Word in google. Anything you can do in MS Word, you can do in C# using the interop libraries. One tip - if you're going down this route - do what you want first in MS Word, recording it as a macro. Then 'edit' the macro. You can almost cut'n'paste the macro code into your C# app.

Like I told you yesterday, C# does not know the file format used for database backups, therefore it cannot restore them unless you know the format well enough to write a decompression algorithm.
If you do, please write an article about it.
