I am trying to search for all available sound input and outut devices and adding their names into a ComboBox.
I am using this code (found here at stackoverflow in a similiar question):
ManagementObjectSearcher mo = new ManagementObjectSearcher("select * from Win32_SoundDevice");
foreach (ManagementObject soundDevice in mo.Get())
{
string deviceId = soundDevice.GetPropertyValue("DeviceId").ToString();
string name = soundDevice.GetPropertyValue("Name").ToString();
comboBox1.Items.Add(name);
}
But this seems to select all available devices, I need to separate input devices and output devices. Is there a simple way of editing this code, or is there a more sophisticated method needed?

I need to programatically find out what graphic card a screen is connected to using C#.
This information is visible in DxDiag, speccy and even in windows advanced display settings view:
But how can I do this in C# myself?
The following is code by #NielW in C# detect which graphics card drives video
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_VideoController");
foreach (ManagementObject mo in searcher.Get())
{
PropertyData currentBitsPerPixel = mo.Properties["CurrentBitsPerPixel"];
PropertyData description = mo.Properties["Description"];
if (currentBitsPerPixel != null && description != null)
{
if (currentBitsPerPixel.Value != null)
System.Console.WriteLine(description.Value);
}
}
}
There is a long talk in the link because they have issues getting multiples graphic cards' names. But this code should work and it shows all names of available graphic cards.
I am currently developing a program that will allow me to detect the serial number of all hard drives in a computer and display them as a barcode.
I have it working on my current machine (Windows 10) and it gets the correct serial numbers (same as what's on the hard drive label) but when I try and use it on a different machine (Windows 7) it just outputs a long string of numbers.
The program is able to detect and output the serial number on my usb fine.
var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach (ManagementObject wmi_HD in searcher.Get())
{
HardDrive hd = new HardDrive();
hd.Model = wmi_HD["Model"].ToString();
hd.SerialNum = Convert.ToString(wmi_HD.GetPropertyValue("SerialNumber"));
hdCollection.Add(hd);
}
This is the current code I am using but the serial number it outputs is: 5635454d4338414e202020202020202020202020
I have tried Win32_LogicalDrive and Win32_Volume but they output the same string.
I have also tried this code snippet:
ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection drives = driveClass.GetInstances();
foreach (ManagementObject drive in drives)
{
HardDrive hd = new HardDrive();
hd.Model = drive["Name"].ToString();
//hd.SerialNum = drive.GetPropertyValue("SerialNumber").ToString();
hd.SerialNum = drive["SerialNumber"].ToString();
}
But this also does not work on the Windows 7 machine.
How could I fix my problem?
First of all, apologies if this doesn't make sense, and/or it has already been asked (although searching didn't find anything).
I have an application which sets default printers for our end users but I would like to expand it by also making it able to install printers from a remote machine as well.
What I need to do is on Form_Load populate a Combo Box with all network shares from the print server.
I am shooting in the dark and am wondering if anyone can shed some light.
I believe this works.
This isnt my code originally but I cant remember where it came from.
using System.Management;
private void btnGetPrinters_Click(object sender, EventArgs e) {
// Use the ObjectQuery to get the list of configured printers.
ObjectQuery oquery = new ObjectQuery("SELECT * FROM Win32_Printer");
ManagementObjectSearcher mosearcher = new ManagementObjectSearcher(oquery);
ManagementObjectCollection moc = mosearcher.Get();
foreach (ManagementObject mo in moc)
{
PropertyDataCollection pdc = mo.Properties;
foreach (System.Management.PropertyData pd in pdc)
{
if ((bool)mo["Network"])
{
cmbPrinters.Items.Add(mo[pd.Name]);
}
}
}
}
I am searching for my USB to Serial converter. I have two objectives:
To get the USB Port Number
To get the Provider
Here under is the screenshot from my Device Manager
Now my motto is to recognize this USB to Serial Bridge which is provided by ATEN, However I am not specifically looking for the ATEN thing, just I need to know how to query ManagementObject
Because if I look for Caption for some systems it is ATEN USB to Serial Bridge and for some systems it is USB-to-Serial Comm. Port, and maybe for some other it will become something else. What never changes is the Provider - "ATEN"
Following is my code:
Now I have did something here under to get/extract data from **CAPTION**
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_PnPEntity WHERE Caption like '%ATEN USB to Serial Bridge%'"))
{
foreach (ManagementObject queryObj in searcher.Get())
{
foreach (PropertyData prop in queryObj.Properties)
{
listBox1.Items.Add(String.Format("{0}: {1}", prop.Name, prop.Value));
}
string s = queryObj["Caption"].ToString();
// Here under i play with the string `s` to get the `CCOM21`
int start = s.IndexOf("(");
int end = s.IndexOf(")");
result = s.Substring(start, end - start);
result = result.Replace("(", "");
list.Items.Add(result);
}
}
I know its not the right way to do but how I can get the COM21 port and Provider - ATEN by query ManagementObject. Or is there any other direct way to do this.
I am able to know the sound devices and USB Devices attached to my PC but not getting any way to find Cameras attached to my machine.
Used below code to get Sound Devices
Console.WriteLine("Win32 SoundDevices\r\n===============================");
ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * from Win32_SoundDevice");
foreach (ManagementObject soundDevice in searcher.Get())
{
//Console.WriteLine("Device found: {0}\n", soundDevice.ToString());
Console.WriteLine("Device found: {0}\n", soundDevice.GetPropertyValue("ProductName"));
}
Console.WriteLine("Search complete.");
I wrote a solution that worked well for me. This method found two USB cameras and an integrated camera on my laptop.
private static async Task ListAllCamerasAsync()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM win32_PNPEntity WHERE PnPClass='Camera'");
var collection = await Task.Run(() => { return searcher.Get(); });
var cameraIndex = 0;
foreach (ManagementObject cameraDevice in collection)
{
Console.WriteLine($"Camera {cameraIndex}: {cameraDevice["Name"]}");
cameraIndex++;
}
}

I'm fairly certain there's no equivalent string you can send to ManagementObjectSearcher() for webcams specifically. There is the "Win32_USBControllerDevice" which you can then determine if it is a webcam or not.
A better solution altogether is to take advantage of DirectShow.NET
