Translation...
an example will need to capture the number of pages that are sent to print and use it in c # ... if someone could help me would appreciate it very much
I would be almost certain that google would be able to find examples of printing. And I suspect the same is true about your other questions. Translated that answer is...
Sería casi seguro que Google sería capaz de encontrar ejemplos de impresión. Y sospecho que lo mismo es cierto acerca de sus otras preguntas.

Your form (or better: an element, e.g. a listview on it) has to subscribe for two events: DragEnter and DragDrop.
In DragEnter do something like:
if (e.Data.GetDataPresent(DataFormats.FileDrop))
e.Effect = DragDropEffects.Copy;
else
e.Effect = DragDropEffects.None;
Now you'll get a "Plus" cursor when you drag the files into the element.
In DragDrop do something like:
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
string[] files = (string[])e.Data.GetData(DataFormats.FileDrop, true);
foreach (string f in files)
{
}
}
Note that you get the filenames.

How do I know whether or not to call ReleaseComObject()?
For example in the following code I call ReleaseComObject() on the Worksheet, it works fine, but I dont rearly know if this is correct or not. How would I know? Is there a rule that I need to follow?
try
{
Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
string strWorkBook = @"C:\zz\Book1.xlsx";
Workbook workBook = excelApp.Workbooks.Open(strWorkBook,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing);
int nSheets = workBook.Sheets.Count;
Worksheet sheet = (Worksheet)workBook.Sheets[1];
Marshal.ReleaseComObject(sheet);
workBook.Close(false, strWorkBook, null);
Marshal.ReleaseComObject(workBook);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

As a rule, its advisable to release com objects from managed code.

MP3 Rearrange is a good example of Object Oriented programming. It uses inheritance 5 levels deep. Overriding methods of base classes is used as well.
Take a look.

Short answer: Classes are nouns and their methods are verbs.
Each class maintains its data, and its methods represent actions on that data.
Ideally, once you write a class (and methods) you use it in the rest of your program like that type was built into the language. The only way the rest of the program interacts with it is through its public methods.

It is possible that you just need to start writing some code. Reading about programming can only get you so far - at some point you must actually do it.

Hi,
How can i retrieve the information about the hardware and services, for a particular client by specifying the computer name or ip address, which is connected in a LAN Network.

In the System.Management namespace you'll find ManagementObject and related classes that access the "Windows Management Instrumentation" subsystem. I suggest you read up on them and look at some of the examples.

Hi,
I have this simple Excel add-in project based on the standard VS template, however, I cannot call the below test() function from Excel VBA.
[Guid("9E88FA9A-4E7D-4bba-8D94-439BFA2B0AEC")]
[ClassInterface(ClassInterfaceType.AutoDual)]
[ComVisible(true)]
public class MyFunctions
{
public void test()
{
Microsoft.Office.Interop.Excel.Application xlsApp = new ApplicationClass();
Worksheet ws = (Worksheet)xlsApp.ActiveSheet;
ws.Cells[1, 1] = "Edited by C#";
}
Please help,
Thanks.

Please state why you can't call the function. Any error message?

Hello to everyone!
I have an ip Camera and I've created an application to display the image there. But I want to be able to control the camera motion from my application. For example, I want to move the camera up, down, right, left, using buttons. How can this be done?
I have read the manual of camera and i have understand that to move the camera should I use the command:
192.168.1.xxxx:xx/decoder_control.cgi?command=[command] (command = 0,1,2,3,4,5)
Can I control the camera using the C#?
Thanks!

Sure if that is the command you need to use. How are we supposed to know?

Yes, this command is correct! for example if I put the command in the address bar of my browser, the camera starts to moving up.
The problem is that I do not know how to do this with C# for my application?

Again, how are we supposed to know? All you have said is that you have a camera and want to control it. We have absolutely no idea what camera you have, how you are connecting to it, what code you are using or anything else. No one reading your post could possbily give you any sort of guidance.
