Ummm...you might want to ask a question instead of just ordering people around.

I have a need to retrieve a list of attached USB HID devices and query their details to populate a list. .Net makes it easy to get a list of devices:
ManagementObjectCollection collection;
using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_PnPEntity Where PNPDeviceID like 'HID%'"))
{
collection = searcher.Get();
}
I can then iterate over the items in the collection and query the properties. Unfortunately the properties do not include the device friendly name e.g. "Big Image Inc Reader".
Is there a native .Net way to get properties such as the friendly name?
I have code that can do this in C++ using DeviceIOControl etc, and it might be that the best approach is to write a non managed C++ wrapper class and invoke it from C#. But native code woud be 'cleaner'.

since WMI doesnt provide what you wish, I think you're stuck with the 'wrapper class' or P/Invoke methodology - two things that may provide inspiration are :-
Simple HID Library - Home[^]
and
HIDSharp[^]
|
|
|
|

Thanks Garth, and sorry to reply so late. The HIDSharp may well be the answer although I have written most of a COM wrapper anyway.

This is how I get the friendly name of my USB serial devices.
The friendly name is in the caption of the management objects. I get them like this:
List<string> usbSerial = new List<string>();
List<ManagementObject> listObj = new List<ManagementObject>();
try
{
string query = "SELECT * FROM Win32_PnPEntity WHERE ConfigManagerErrorCode = 0";
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
listObj = searcher.Get().Cast<ManagementObject>().ToList();
searcher.Dispose();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
usbSerial = new List<string>();
}
foreach (ManagementObject obj in listObj)
{
object captionObj = obj["Caption"];
if (captionObj != null)
{
string caption = captionObj.ToString();
if (caption.Contains("(COM"))
{
usbSerial.Add(caption);
}
}
}
usbDevices = usbSerial.Distinct().OrderBy(s => s).ToArray();
Hope this can help,

I have a shared dll (model.dll) and two executables using it. In teh model library i have a property. In the one executable i would like to set [ReadOnlyAttribute(false)] for the property and in the other executable i would like to set [ReadOnlyAttribute(true)]. Using the conditional compilation settings in the respertive project properties does not do the trick. Does anybody have a suggestion for me?
|
|

|

Conditional compilation is just that: a compile time operation.
If you have two exes using the same DLL, then they will have the same attributes, because the compilation is only done once and the same assembly is being referenced. You can't use it to switch attribute settings at run time!
If you want two different attribute settings, then you need to build two separate DLL files - which kinda defeats the point of having it as a DLL in the first place!

that's clear! Thanks for the reply.
Is there realy no smart alternative you can think of?
(I use the propertyGrid control)

A decorator, or a TypeConverter that returns a specific set of properties depending on the EntryAssembly.

As you stated in your last reply to OriginalGriff that you want to use this for a PropertyGrid: Take a look at this article: PropertyGrid utilities[^] - I saw a similar question on another website where one of the answerers said he solved it with the code from that article.

Agreed with OriginalGriff and Sascha, but the big question I would ask is: why do you want this?

the one executable is meant for configution, the other for execution. When executing the operator must not be able to change the properties, but he can observe them.

Out of the top of my head, I think you should
- create some sort of ConfigurationAPI class that resides in your dll
- you can even apply some credentials at construction (just throw if credentials aren't right)
- then the properties you want to configure can all be "internal set" - this way, in your ConfigurationAPI class you can configure away

{
MemoryStream memt4 = new MemoryStream();
Document doc4 = new Document(iTextSharp.text.PageSize.A4, 80, 80, 42, 35);
doc4.SetPageSize(iTextSharp.text.PageSize.A4.Rotate());
PdfWriter wrik4 = PdfWriter.GetInstance(doc4, memt4);
var ft4 = FontFactory.GetFont("Times New Roman", 9, BaseColor.RED);
var gt4 = FontFactory.GetFont("Times New Roman", 12, BaseColor.BLACK);
var NaFirt4 = FontFactory.GetFont("Calibri", 12, BaseColor.DARK_GRAY);
var NaFirBot4 = FontFactory.GetFont("Calibri", 12, BaseColor.DARK_GRAY);
doc4.Open();
PdfContentByte cbt4 = wrik4.DirectContent;
PdfPTable tabled4 = new PdfPTable(1) { WidthPercentage = 100, RunDirection = PdfWriter.RUN_DIRECTION_LTR, ExtendLastRow = false };
tabled4.TotalWidth = 600f;
tabled4.DefaultCell.UseAscender = true;
tabled4.DefaultCell.UseDescender = true;
PdfContentByte ct4 = wrik4.DirectContent;
tabled4.HeaderRows = 1;
PdfPCell ceko = new PdfPCell(new Phrase("Naglówek"));
ceko.VerticalAlignment = Element.ALIGN_CENTER;
ceko.HorizontalAlignment = Element.ALIGN_CENTER;
ceko.BorderWidth = 2;
ceko.BorderColor = new BaseColor(Color.Red);
tabled4.AddCell(ceko);
tabled4.SplitLate = false;
tabled4.SplitRows = true;
for (int j = 0; j < 300; j++)
{
PdfPCell cek4 = new PdfPCell(new Phrase(String.Format("{0}", j)));
tabled4.AddCell(cek4);
}
int pageRows4 = 0;
while (pageRows4 < tabled4.Rows.Count + 20)
{
tabled4.HeaderRows = 1;
tabled4.HorizontalAlignment = Element.ALIGN_TOP;
tabled4.WriteSelectedRows(pageRows4, pageRows4 + 21, 200, 500, ct4);
pageRows4 = pageRows4 + 21;
doc4.NewPage();
}
doc4.Close();
wrik4.Close();
PdfReader readt4 = new PdfReader(memt4.ToArray());
PdfStamper stampt4 = new PdfStamper(readt4, new FileStream(Konfi.Rpath + "Test_4 " + Konfi.RfileName + ".pdf", FileMode.Create, FileAccess.Write, FileShare.None));
stampt4.FormFlattening = true;
stampt4.Close();
}

Hi
A few starter questions regarding the Facebook IOS/Web
1) for IOS is there a development tool that I can get in the App Store or can I use Visual Studio that I use in Windows
2) is C# the only language to for the Facebook SDK
3) for Facebook web development can I use visual studio
Thanks
|
|
|
|

In every case I think you need to go to the Facebook developer site and study their documentation.
|
|
|
|
|
I think I'll stick to Windows MFC
Thanks
|
|
|

I think that is a sensible decision for now  . However, I would say that given your experience of C++/MFC you may find C# and .NET not too difficult to learn. I started with C# by working through .NET Book Zero by Charles Petzold[^], which lays everything out in clear and concise terms.
