I'm working on a bug reporting tool for my application, and I'd like to attach hardware information to bug reports to make pinpointing certain problems easier. Does anyone know of any Win32 API functions to query the OS for information on the graphics and sound cards?
Thanks,
Rob
If your willing to dig into WMI the following should get you started.
using System;
using System.Management;
namespace WMIData
{
class Program
{
static void Main(string[] args)
{
SelectQuery querySound = new SelectQuery("Win32_SoundDevice");
ManagementObjectSearcher searcherSound = new ManagementObjectSearcher(querySound);
foreach (ManagementObject sound in searcherSound.Get())
{
Console.WriteLine("Sound device: {0}", sound["Name"]);
}
SelectQuery queryVideo = new SelectQuery("Win32_VideoController");
ManagementObjectSearcher searchVideo = new ManagementObjectSearcher(queryVideo);
foreach (ManagementObject video in searchVideo.Get())
{
Console.WriteLine("Video device: {0}", video["Name"]);
}
Console.ReadLine();
}
}
}
WMI .NET Overview
After posting noticed it wasn't marked .NET, however this could be of interest as well. Creating a WMI Application Using C++
I think your best bet is the DirectSound API, documented here:
http://msdn.microsoft.com/en-us/library/bb219833%28VS.85%29.aspx
Specifically, the DirectSoundEnumerate call.

I'm trying to make an application which can communicate with android studio, but IntelliJ plugin SDK is not giving me enough option to build the features that I want, so I'm thinking about trying a different approach to create a separate windows application for functionality but as application needs to know the project folder that is currently opened with android studio, I'm trying to search the same from 4-5 days but haven't found anything helpful if this is possible to read folder location of open project in android studio with a different application please help me, if there is some way that building plugin that can send location to external application please tell me.
Thank you
Just manage to achieve the same with WPF, still don't know if electron can do it or not
if someone is finding the answer for this here's my approach, not the best and final but just figured out how I can do it make sure you will optimize code before implementation
private void Button_Click(object sender, RoutedEventArgs e)
{
var allProcesses = Process.GetProcesses();
String data = "";
for(int a =0; a < allProcesses.Length; a++)
{
Console.WriteLine(data);
if (allProcesses[a].MainWindowTitle.Contains("Android"))
{
Console.WriteLine(data);
data = allProcesses[a].MainWindowTitle;
if(data.Contains("["))
{
data = data.Substring(data.IndexOf("["));
data= data.Substring(0, data.IndexOf("]") + 1);
data = data.Replace("[", "");
data = data.Replace("]", "");
Console.WriteLine(data);
MessageBox.Show(data);
return;
}
else
{
MessageBox.Show("Project is not open in Android Studio");
return;
}
}
}
MessageBox.Show("Android Studio Not Running");
return;
}
I'm going to write a Windows application and it would be useful if the app could tell what graphics card is being used. At the least, it would be helpful to see the manufacturer of the GPU. I'm not set on a programming language as of yet.
What windows library exposes this information?
See here for a C# way of doing it, using WMI. You could access WMI through pretty much any language:
C# detect which graphics card drives video
ManagementObjectSearcher searcher
= new ManagementObjectSearcher("SELECT * FROM Win32_DisplayConfiguration");
string graphicsCard = string.Empty;
foreach (ManagementObject mo in searcher.Get())
{
foreach (PropertyData property in mo.Properties)
{
if (property.Name == "Description")
{
graphicsCard = property.Value.ToString();
}
}
}
I have a windows service that can create an executable in the users windows session, via calling the "CreateProcessAsUser" function. This works fine as long as there is a windows session already there. In the case that there isn't one already I'd like to be able to create one programmatically. Is this is possible? Can't seem to find a function to do it.
This isn't quite the solution for the question I asked, but it was the solution that helped achieve what I was trying to achieve by asking this question, if you see what I mean.
Rather than have having a windows services that creates a server session you can configure windows to automatically logon at boot time. This still means someone could accenditally log off, but cures the main reason for sessions disappearing: the server being rebooted. Use the following steps to activate auto-logon:
Press the Windows key + R on your keyboard to launch the “Run” dialog box.
Type regedit and hit enter to open the Registry Editor
Then browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\
Set AutoAdminLogon = 1 (create it if doesn't exist its a string variable)
Set DefaultUserName = your username (create it if doesn't exist its a string variable)
Set DefaultPassword = your password (create it if doesn't exist its a string variable)
Instructions were taken from this post:
http://channel9.msdn.com/Blogs/coolstuff/Tip-Auto-Login-Your-Windows-7-User-Account
You cannot create a new session from a service. Sessions are managed by the OS. New ones get created when users logon interactively.
#Robert, I know this is an old question and that you've already found something that works for you but in my case I was looking for something similar to your original question and I did finally figure it out so I thought I'd share. My solution uses only .NET and a COM reference not the Win32 API mentioned in your title, but I'm guessing that wasn't really a requirement for you.
I've written a simple utility to using the Remote Desktop ActiveX control (COM Reference). If you paste this code into a Class Library you can then call it by simply passing in the server, username, domain, and password and everything is done for you without any other interaction required. Once the method is complete you can then call your "CreateProcessAsUser" Code. I've written this utility in a way so that you could call it every time but initiating an RDP session takes several seconds so for performance sake I'd suggest you write another method to enumerate the sessions and see if your user is logged in and only call this utility when you determine that your user isn't logged in (That's what I did in my actual project). If you feel you need help with that post in the comments and I'll share how I did that but It's not really part of this question so for now I'm leaving it out.
Here's a link back to my question that has a few more requirements/details than this question.
Create Windows Session programmatically from Console or Windows Service
And here's my RDP utility. After you put this code in a class library you can then call it from a console app, winForms app, or from a windows service running on the same machine or from a remote machine.
using System;
using System.Diagnostics;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;
using AxMSTSCLib;
namespace Utility.RemoteDesktop
{
public class Client
{
private int LogonErrorCode { get; set; }
public void CreateRdpConnection(string server, string user, string domain, string password)
{
void ProcessTaskThread()
{
var form = new Form();
form.Load += (sender, args) =>
{
var rdpConnection = new AxMSTSCLib.AxMsRdpClient9NotSafeForScripting();
form.Controls.Add(rdpConnection);
rdpConnection.Server = server;
rdpConnection.Domain = domain;
rdpConnection.UserName = user;
rdpConnection.AdvancedSettings9.ClearTextPassword = password;
rdpConnection.AdvancedSettings9.EnableCredSspSupport = true;
if (true)
{
rdpConnection.OnDisconnected += RdpConnectionOnOnDisconnected;
rdpConnection.OnLoginComplete += RdpConnectionOnOnLoginComplete;
rdpConnection.OnLogonError += RdpConnectionOnOnLogonError;
}
rdpConnection.Connect();
rdpConnection.Enabled = false;
rdpConnection.Dock = DockStyle.Fill;
Application.Run(form);
};
form.Show();
}
var rdpClientThread = new Thread(ProcessTaskThread) { IsBackground = true };
rdpClientThread.SetApartmentState(ApartmentState.STA);
rdpClientThread.Start();
while (rdpClientThread.IsAlive)
{
Task.Delay(500).GetAwaiter().GetResult();
}
}
private void RdpConnectionOnOnLogonError(object sender, IMsTscAxEvents_OnLogonErrorEvent e)
{
LogonErrorCode = e.lError;
}
private void RdpConnectionOnOnLoginComplete(object sender, EventArgs e)
{
if (LogonErrorCode == -2)
{
Debug.WriteLine($" ## New Session Detected ##");
Task.Delay(10000).GetAwaiter().GetResult();
}
var rdpSession = (AxMsRdpClient9NotSafeForScripting)sender;
rdpSession.Disconnect();
}
private void RdpConnectionOnOnDisconnected(object sender, IMsTscAxEvents_OnDisconnectedEvent e)
{
Environment.Exit(0);
}
}
}
What about the LogonUser function?
http://winapi.freetechsecrets.com/win32/WIN32LogonUser.htm
For connecting to webservices i wrote the following code.
WebClient wc = new WebClient();
wc.DownloadStringAsync(new Uri("http://www.Webservices.asmx"));
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted);
void wc_DownloadStringCompleted(object sender,DownloadStringCompletedEventArgs e)
{
Debug.WriteLine("Web service says: " + e.Result);
using (var reader = new StringReader(e.Result))
{
String str = reader.ReadToEnd();
}
}
by using above code Get the string result.But i want get the result in HTMLVisulaizer then i know the what are the methods having that webservice.then i can easily access the particular method.
Please tell me how to call a web service method in Windows phone 7?in webservice i am having 5 webmethods.how to get that and how to call the Particular webmenthod.
Please tell me thanks in advance.
#venkateswara Are you talking about obtaining a list of known WebReference methods so you know which one to call in you code? Do you not see the this of known method calls when you add the WebReference to your WP7 project? Since you will be developing the WP7 app in VS I can't see the reason you would want to do this. Even if you don't own the webservice yourself, you will need to connect to it from VS in order to add the reference to your project.
Below is the screen in VS2010 where a WebReference is added. The Operations are listed on the right.
Once added you can use the ObjectBrowser to understand how the methods should be called.
Please let me know if I have missed something from your question.
#Jason James
The first step:
You must add referent Services ,like Jason James has very detailed instructions .
step 2 :
You can open App.xaml.cs , in Functions Apps
public Apps()
{
// Global handler for uncaught exceptions.
UnhandledException += Application_UnhandledException;
// Show graphics profiling information while debugging.
if (System.Diagnostics.Debugger.IsAttached)
{
// Display the current frame rate counters.
Application.Current.Host.Settings.EnableFrameRateCounter = true;
// Show the areas of the app that are being redrawn in each frame.
//Application.Current.Host.Settings.EnableRedrawRegions = true;
// Enable non-production analysis visualization mode,
// which shows areas of a page that are being GPU accelerated with a colored overlay.
//Application.Current.Host.Settings.EnableCacheVisualization = true;
}
// You can declare objects here that you will use
//Examlpe: NameservicesReferent.(Function that returns services) = new NameservicesReferent.(Function that returns services)();
Ws_Function = new Nameservices.ServiceSoapClient();
}
step 3:
in Mainpage.xaml.cs
GlobalVariables.Ws_advertise.getLinkAdvertiseIndexCompleted += new EventHandler<advertise.getLinkAdvertiseIndexCompletedEventArgs>(Ws_advertise_getLinkAdvertiseIndexCompleted);
GlobalVariables.***NameWedservise***.getLinkAdvertiseIndexAsync("**parameters to be passed**");
step 4:
void Ws_advertise_getLinkAdvertiseIndexCompleted(object sender, advertise.getLinkAdvertiseIndexCompletedEventArgs e)
{
//function returns the results to you, the example here is an array
string[] array = null;
try
{
array = e.result;
if(array != null)
}
cath(exception ex)
{
}
finally
{
array = null;
GlobalVariables.Ws_advertise.getLinkAdvertiseIndexCompleted -= new EventHandler<advertise.getLinkAdvertiseIndexCompletedEventArgs>(Ws_advertise_getLinkAdvertiseIndexCompleted);
}
}
I'm working with the Beta 2 version of Visual Studio 2010 to get some advanced learning using WF4. I've been working with the SqlTracking Sample in the WF_WCF_Samples SDK, and have gotten a pretty good understanding of how to emit and store tracking data in a SQL Database, but haven't seen anything on how to query the data when needed. Does anyone know if there are any .Net classes that are to be used for querying the tracking data, and if so are there any known samples, tutorials, or articles that describe how to query the tracking data?
According to Matt Winkler, from the Microsoft WF4 Team, there isn't any built in API for querying the tracking data, the developer must write his/her own.
These can help:
WorkflowInstanceQuery Class
Workflow Tracking and Tracing
Tracking Participants in .NET 4 Beta 1
Old question, I know, but there is actually a more or less official API in AppFabric: Windows Server AppFabric Class Library
You'll have to find the actual DLL's in %SystemRoot%\AppFabric (after installing AppFabric, of course). Pretty weird place to put it.
The key classes to look are at are SqlInstanceQueryProvider, InstanceQueryExecuteArgs. The query API is asynchronous and can be used something like this (C#):
public InstanceInfo GetWorkflowInstanceInformation(Guid workflowInstanceId, string connectionString)
{
var instanceQueryProvider = new SqlInstanceQueryProvider();
// Connection string to the instance store needs to be set like this:
var parameters = new NameValueCollection()
{
{"connectionString", connectionString}
};
instanceQueryProvider.Initialize("Provider", parameters);
var queryArgs = new InstanceQueryExecuteArgs()
{
InstanceId = new List<Guid>() { workflowInstanceId }
};
// Total ruin the asynchronous advantages and use a Mutex to lock on.
var waitEvent = new ManualResetEvent(false);
IEnumerable<InstanceInfo> retrievedInstanceInfos = null;
var query = instanceQueryProvider.CreateInstanceQuery();
query.BeginExecuteQuery(
queryArgs,
TimeSpan.FromSeconds(10),
ar =>
{
lock (synchronizer)
{
retrievedInstanceInfos = query.EndExecuteQuery(ar).ToList();
}
waitEvent.Set();
},
null);
var waitResult = waitEvent.WaitOne(5000);
if (waitResult)
{
List<InstanceInfo> instances = null;
lock (synchronizer)
{
if (retrievedInstanceInfos != null)
{
instances = retrievedInstanceInfos.ToList();
}
}
if (instances != null)
{
if (instances.Count() == 1)
{
return instances.Single();
}
if (!instances.Any())
{
Log.Warning("Request for non-existing WorkflowInstanceInfo: {0}.", workflowInstanceId);
return null;
}
Log.Error("More than one(!) WorkflowInstanceInfo for id: {0}.", workflowInstanceId);
}
}
Log.Error("Time out retrieving information for id: {0}.", workflowInstanceId);
return null;
}
And just to clarify - this does NOT give you access to the tracking data, which are stored in the Monitoring Database. This API is only for the Persistence Database.
