The hardwareID contains a vendorID and a productID, these obviously come from data inside the device.
The location is where the device currently sits, so obviously it does not come from inside the device.
FYI: this information can also be obtained manually following this path on Win10:
My PC/Properties/Device Manager/Ports...

Ok, that sounds great, then I will stop comparing the description string and compare the HID string instead. Thank you for your help!

hi
I have project of type Console .net framework 4.6.1. A simple hello world. No dependencies. No references.
When I right click and try publishing this project, it goes into manifest mode of publishing. Where do I change settings to make it a traditional simpler Publish, so I get a .exe file without manifest files. So that, the Publish folder can be copy pasted to any computer and it runs without issues.
Some research suggested to uncheck LINKER, but this is not available in Projects --> Properties --> Configuration
thank you

All you do is look in your project bin\Release folder. It's right there every time you compile the project, so long as you change the configuration from Debug to Release.
All you for such a simple app is the .exe.
Now, if the machine you're running the project on doesn't already have the .NET Framework 4.6.1, or higher, installed already, you're going to have to install that before your app will run.

This query is bit long, and it returns the correct data, but it takes about 4 minutes to run. I'd like to speed it up. The first part with the query runs pretty quick. The FOREACH loop part is the bottleneck.
Inside the FOREACH are 4 queries. They are all the same, except they pull from 4 different tables (JobHardwareVendors, JobLumberVendors, EquipmentHardwareVendors, TrussHardwareVendors). Those tables each have the same structure.
Those inner queries look like this:
/*********************************************************

*********************************************************/
var vendors = (from v in db.JobHardwareVendors
join c in db.Companies on v.VendorId equals c.Id
where v.JobId == result.Id &&

select new CompanyHeaderEntity
{
Id = c.Id,
CompanyName = c.CompanyName,
StatusId = c.StatusId
}).Distinct().ToList();
result.HardwareCompanies.AddRange(vendors.Where(x => x.StatusId == companyStatuseActive.Id));
foreach (var vendor in vendors)
{
result.VendorInitials += GetInitials(vendor.CompanyName) + ",";
}
Here's the entire method

If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

No.
That is a poor attempt at a password cracker, which is a product designed to circumvent legitimate security measures.

Hi this is just for education purpose. I don't think there is any legitimate system that can be cracked that way.
Obviously most if not all systems will lock an account after a few attempts

Your homework is to write malicious code?
Yeah, right ... We don't do your homework either, malicious or not.

Oh really? How naive of you to try to write something that's already been done innumerable times then.
Why would anyone want to write something like this? BECAUSE THEY ACTUALLY WORKED ON REAL SYSTEMS!
You don't need to check the hashed password against the real system. All you need is a copy of the account database. You can then run as many checks as you want against the database with nothing "locking you out after a few attempts".

Hi!
I am trying to find the best way to transform a list of objects and sort based on custom order:
I have a list of profile duplicates, and need to find "top" profile based on a priority order. The top profile need to be transformed into a new object with 3 properties. These 3 properties also dictate the sort order.
The 3 new enum-based properties are:
ProfileType with types (SuperUser > NormalUser > Beginner),
ProfileSubType with types (Internal > External),
ProfileValidity with types (Valid > ValidInFuture > Expire)
The properties are based on enums from an external source and are out of order, so I need to have my own custom sort for each of them.
So e.g. a prioritized list would look like:
{Superuser, Internal, Valid},
{Superuser, Internal, Expired},
{Superuser, External, Valid},
{Normaluser, Internal, Valid},
{Beginner, Internal, Expire}
Right now my solution is this:
TransformedProfile = profileList.Select(x => new TransformedProfile
{
ProfileType = GetProfileType(x.PropertyA),
ProfileSubType = GetProfileSubType(x.PropertyB),
ProfileValidity = GetValidity(x.StartDate, x.ExpiryDate)
})
.OrderBy(y => typePriorityDict[y.ProfileType])
.ThenBy(y => subTypePriorityDict[y.ProfileSubType])
.ThenBy(y => validityPriorityDict[y.ProfileValidity])
.FirstOrDefault();
The typePriorityDict, subTypePriorityDict, validityPriorityDict are dictionaries with my custom sort order.
This solution works ok and gives me the desired result. But I was wondering if there are more efficient ways of doing this?

You could implement IComparable and IComparer[^] in your class, and as a bonus you gain equality, greater than, and less than operators for the class directly.
Your sorting then becomes a whole load more readable.

Only if you implement them yourself, although the implementation is fairly trivial.
public static bool operator <(Foo left, Foo right) => left is null || left.CompareTo(right) < 0;
public static bool operator <=(Foo left, Foo right) => left is null || left.CompareTo(right) <= 0;
public static bool operator >=(Foo left, Foo right) => left != null && left.CompareTo(right) >= 0;
public static bool operator >(Foo left, Foo right) => left != null && left.CompareTo(right) > 0;

It looks like you are only looking for the highest single item, not getting a complete sorted list, which is what your question seems to imply that you are looking for. But on the assumption that the .FirstOrDefault does give you what you want ...
I am not sure whether any efficiency savings would be sufficiently significant, but I would consider combining the priorities into a single value using const / enums rather than using dictionary lookups and only sorting the list once against a single key. e.g. (my C# is a little rusty, so forgive syntax errors)
[Flags]
enum YourRevisedPriority
{
SuperUser = &x0000,
NormalUser = &x0100,
Beginner = &x0200,
Internal = &x0000,
External = &x0010,
Valid = &x0000,
ValidInFuture = &x0001,
Expire = &x0002
}
TransformedProfile = profileList.Select(x => new TransformedProfile
{
ProfileType = GetProfileType(x.PropertyA),
ProfileValidity = GetValidity(x.StartDate, x.ExpiryDate),
NewPriority =
(ProfileType == SourceEnum.SuperUser ? YourRevisedPriority.SuperUser : (ProfileType == SourceEnum.NormalUser ? YourRevisedPriority.NormalUser : YourRevisedPriority.Beginner)) +
(GetProfileSubType(x.PropertyB) == SourceEnum.Internal ? YourRevisedPriority.Internal : YourRevisedPriority.External) +
(ProfileValidity == SourceEnum.Valid ? YourRevisedPriority.Valid : (ProfileValidity == SourceEnum.ValidInFuture ? YourRevisedPriority.ValidInFuture : YourRevisedPriority.Expire))
})
.OrderBy(y => y.NewPriority)
.FirstOrDefault();

Thanks for the suggestions!  I ended up following @OriginalGriff suggestion and implemented IComparer for the TransformedProfile and IComparer for a custom sort-list, to allow for some short-circuit comparison (and also allowed me to put not-found values last in the sort).
Thanks!

Hello all,
So basically, in my programming the user can press the default key that i have set, which is F1, to enable a feature. However, i want the user to be able to change this key. so for example, a dialog pops up and asks them to enter the key they want to set for that feature then it changes the F1 (default key) to the new key that the user chose. How do i do this?
|
|
|
|
|
Firstly, don't use F1 for that: the Windows standard use for F1 is "Help", and it's a bad idea to "play" with standard keys - the user can if he wishes, but you shouldn't as it gets confusing.
The simplest way is to have a Dictionary of keys, and Func values:
private Dictionary<Keys, Func<int>> keyFunctions = new Dictionary<Keys, Func<int>>();
private int A()
{
Console.WriteLine("A");
return 1;
}
private int B()
{
Console.WriteLine("B");
return 2;
}
private int C()
{
Console.WriteLine("C");
return 3;
}
...
keyFunctions.Add(Keys.A, A);
keyFunctions.Add(Keys.B, B);
keyFunctions.Add(Keys.C, C);
...
You can then call the method by accessing the Dictionary with the Key value:
Console.WriteLine(keyFunctions[Keys.C]());
Console.WriteLine(keyFunctions[Keys.B]());
Console.WriteLine(keyFunctions[Keys.A]());
You can use Action instead of Func if your methods do not return a value, but that makes the Add operation more complex:
keyFunctions.Add(Keys.A, () => A());
keyFunctions.Add(Keys.B, () => B());
keyFunctions.Add(Keys.C, () => C());
You can then change the Keys value as you need, and process the Dictionary in your Forms ProcessCmdKey override provided you have set the Form.KeyPreview to true.

I am working to build up a GPIB : VISA driver for the IVI and NI models. There is very spare code examples and documentation without some guidance is difficult. Can anyone point me in the right direction. Note the older NationalInstrument.VISANS driver will no longer compile or work under VS2019.
If you have any example code that would be cool.
|
|
|
|
|
|
|
This is why I don't use the NI NET assemblies: the good old Visa32.dll (C/C++ style, not NET) didn't change since probably 20 years and does not depend on the VS version because it binds at runtime only (NB. see answer to your question about my article/software). It is less user friendly than IVI though, I admit.

For the next C# version I would like the ability to have multiple classes with the same name.
But, this is for POCO's
What do I mean?
I have an poco with the name CandidateFunction
public class CandidateFunction
{
public int CandidateFunctionId { get; set; }
public int CandidateId { get; set; }
public int FunctionId { get; set; }
public string Skills { get; set; }
public DateTime Date { get; set; }
}
As you can see, the property with the name Skills is a string.
It can be a long string and it stores one or more Skills.
But customers want to see Skills as a list so I have another POCO
public class CandidateFunctionWithSkillsList
{
public int CandidateFunctionId { get; set; }
public int CandidateId { get; set; }
public int FunctionId { get; set; }
public List<Skill> Skills { get; set; }
public DateTime Date { get; set; }
}
It has another name.
Now, I want both POCO's with the same name. I know there alternatives for what I want but I don't like them.
So, when I instantiate a new CandidateFunction, I want a popup asking me which one I want to use.
Will this ever happen and if not, why not?
