How about starting to do some research on your own before you post these very broad open-ended questions ?
Like: searching CodeProject, and reading relevant articles here ?

If you just want to disable/enable all USB ports you can use this code. Note, you must have administrator privileges to change the registry.
Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 4, Microsoft.Win32.RegistryValueKind.DWord);
Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 3, Microsoft.Win32.RegistryValueKind.DWord);

Here is my code. I Get the printticket from print job. I Need Printjob informations like copycount, media size, media type, duplex printing and other details. But I can default values from the printticket like copycount is always 1 and sometime no. of pages in job also comes 0. Now struggle with this problem. I Need Help to solve this problem.
PrintServer myPrintServer = new PrintServer(@"\\MyMachine");
PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();
foreach (PrintQueue pq in myPrintQueues)
{
if (pq.QueueStatus != PrintQueueStatus.Error)
{
foreach (PrintSystemJobInfo job in pq.GetPrintJobInfoCollection())
{
if (bNewJob == true)
{
PrintTicket pt = job.HostingPrintQueue.CurrentJobSettings.CurrentPrintTicket;
UpdateText("Current Copies : " + pt.CopyCount.Value.ToString());
UpdateText("Default Copies : " + dpt.CopyCount.Value.ToString());
UpdateText("User Copies : " + upt.CopyCount.Value.ToString());
UpdateText("Full Name :" + job.HostingPrintQueue.FullName.ToString());
UpdateText("Job ID : " + job.JobIdentifier.ToString());
UpdateText("Job Name : " + job.JobName.ToString());
DateTime dt = job.TimeJobSubmitted;
UpdateText("Submitter :" + job.Submitter.ToString());
UpdateText("Date:"+dt.Day.ToString()+"/"+dt.Month.ToString()+"/"+ dt.Year.ToString());
UpdateText("Hosted Server :" + job.HostingPrintServer.Name.ToString());
UpdateText("No of Pages :" + job.NumberOfPages.ToString());
}
}
}
}
Have A Nice Day!

While this project I'm on is MVC, this question isn't specific to MVC, so I felt like this was the right place. Anyhow, we are using the Repository pattern for data access. One particular entity type, e.g. SharedObj, has several other entity types that the SharedObj entity can be tied to. Each is an IEnumerable, like this:
public class SharedObj
{
IEnumerable<Obj1> Obj1s;
IEnumerable<Obj2> Obj2s;
IEnumerable<Obj3> Obj3s;
}
So when we add a child object to one of those collections of SharedObj, we have a method like this:
public void AddObj(ObjType objType, int objId)
{
switch (objType)
{
case ObjType.Obj1:
entity.Obj1s.Add(GetRepository<Obj1>().GetByID(objId);
break;
case ObjType.Obj2:
entity.Obj2s.Add(GetRepository<Obj2>().GetByID(objId);
break;
case ObjType.Obj3:
entity.Obj3s.Add(GetRepository<Obj3>().GetByID(objId);
break;
}
}
"ObjType" is an enumeration of object types. The "GetRepository" method calls "DependencyResolver.Current.GetService<irepository<t>>();" and we use Unity for dependency injection.
Is there a way to make a more generic "Add" call based on the supplied "ObjType"? Or is this the only concept that can be applied in order to achieve what we're doing?

Map an Action to the enum in a dictionary and execute the appropriate entry when you need to use it.
|
|
|
|

Similar to what Pete said; I'd prefer to use a Dictionary<type,List<whatever>>
And I think that having AddObj perform GetRepository and GetByID violates the Single Responsibility Principle.
By passing in the object, you could probably also leverage generics and simplify things even more.

You mean like PayPal or something? Where are you stuck? You'll have to contact whatever vendor you want to work with and get their SDK documentation.
There are only 10 types of people in the world, those who understand binary and those who don't.

I don't know of any products that will integrate with multiple payment processors, although there probably are some.
If you want to use PayPal then refer to https://developer.paypal.com/docs/api/[^]

Hi every one.
I want to create all rhythmic figures in music. I have an array for durations:
public static double[] duration_fltarray = new double[7];
duration_fltarray[0] = 1;
duration_fltarray[1] = 0.5;
duration_fltarray[2] = 0.25;
duration_fltarray[3] = 0.125;
duration_fltarray[4] = 0.625;
duration_fltarray[5] = 0.3125;
duration_fltarray[6] = 0.15625;
This array shows music times: 1 - 1/2 - 1/4 - 1/8 and so on.
I think it should be written by recursive function, because I couldn't do it by while and for loop.
Now, I need all sorted figures that sum of them are equal 1. For example:
1
1/2 - 1/2
1/2 - 1/4 - 1/4
1/4 - 1/2 - 1/4
1/4 - 1/4 - 1/2
1/4 - 1/4 - 1/4 - 1/4
1/8 - 1/2 - 1/4 - 1/8
1/8 - 1/2 - 1/8 - 1/4
1/8 - 1/2 - 1/8 - 1/8 - 1/8
...
Of course, number of figures will be too many more if we add 1/16 and 1/32 and ... .
I can print them in a web page(response.write) or in a c console; it's not important. But the algorithm should be as simple as possible.
Thank you all.
