C# WUApiLib: Failing to Install Updates with 0x80240024 Even Though Updates are Found

I have followed instructions found on this site, which was found when I researched Stack Overflow and found this question. However, I can't seem to figure out why my code is hitting the catch block. I have a break at the IInstallationResult line, which the code hits but then goes to the catch, stating 0x80240024 (There are no updates), even though there are certainly updates available and I list them in the text box.
What am I missing here?
using System;
using System.Windows.Forms;
using WUApiLib;
namespace TEST.DetectWindowsUpdate
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void GetUpdates(bool downloadUpdates, bool installUpdates)
{
UpdateSession uSession = new UpdateSession();
IUpdateSearcher uSearcher = uSession.CreateUpdateSearcher();
UpdateCollection updatesToInstall = new UpdateCollection();
UpdateDownloader downloader = uSession.CreateUpdateDownloader();
IUpdateInstaller installer = uSession.CreateUpdateInstaller();
uSearcher.Online = true;
try
{
ISearchResult sResult = uSearcher.Search("IsInstalled=0 And Type='Software'");
lblUpdateCount.Text = sResult.Updates.Count.ToString();
foreach (IUpdate update in sResult.Updates)
{
txtUpdatesList.AppendText("Title: " + update.Title + Environment.NewLine);
txtUpdatesList.AppendText("IsInstalled: " + update.IsInstalled.ToString() + Environment.NewLine);
txtUpdatesList.AppendText("Downloaded: " + update.IsDownloaded.ToString() + Environment.NewLine);
txtUpdatesList.AppendText("IsMandatory: " + update.IsMandatory.ToString() + Environment.NewLine);
txtUpdatesList.AppendText(Environment.NewLine);
if (downloadUpdates)
{
if (update.IsDownloaded == false)
{
do
{
downloader.Updates.Add(update);
downloader.Download();
}
while (update.IsDownloaded == false);
if (update.IsDownloaded == true)
{
updatesToInstall.Add(update);
}
}
else
{
updatesToInstall.Add(update);
}
}
if (installUpdates)
{
installer.Updates = updatesToInstall;
IInstallationResult installationRes = installer.Install();
for (int i = 0; i < updatesToInstall.Count; i++)
{
txtUpdatesList.AppendText("Installing " + updatesToInstall[i].Title + "...");
if (installationRes.GetUpdateResult(i).HResult == 0)
{
txtUpdatesList.AppendText("INSTALL SUCCESS FOR " + updatesToInstall[i].Title);
}
else
{
txtUpdatesList.AppendText("INSTALL FAIL FOR " + updatesToInstall[i].Title);
}
}
}
}
}
catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message + ": " + ex.HelpLink);
}
}
private void btnGetUpdates_Click(object sender, EventArgs e)
{
base.OnLoad(e);
txtUpdatesList.Clear();
GetUpdates(false, false);
}
private void btnInstallUpdates_Click(object sender, EventArgs e)
{
base.OnLoad(e);
txtUpdatesList.Clear();
GetUpdates(true, true );
}
}
}

Turns out it was an issue with privileges. I ran as administrator and it functioned appropriately.

Form without movement when filling in DataGridView

I use a DataGridView as a console for an application, I need to fill it out every second, I use the following code for this:
public class dgView
{
public static DataGridView DataConsole;
public static void addLinha(int tipo_acao, string acao, string extra, int tipo_extra)
{
// INSERE LINHA NO CONSOLE
try
{
if (DataConsole == null) return;
var idLinha = DataConsole.Rows.Add();
using (var linha = DataConsole.Rows[idLinha])
{
//await Task.Delay(300);
if (tipo_acao == 0)
{
linha.DefaultCellStyle.ForeColor = Color.Teal;
linha.Cells[3].Style.ForeColor = Color.Gray;
}
else if (tipo_acao == 1)
{
linha.DefaultCellStyle.ForeColor = Color.Yellow;
linha.Cells[3].Style.ForeColor = Color.Orange;
}
else
{
linha.DefaultCellStyle.ForeColor = Color.Red;
linha.Cells[3].Style.ForeColor = Color.Magenta;
}
linha.Cells["dg_data"].Value = DateTime.Now;
linha.Cells["dg_mapa"].Value = "" + Config.Mapa + "";
linha.Cells["dg_acao"].Value = "" + Config.rm.GetString("" + acao + "") + "";
if (tipo_extra == 0)
{
linha.Cells["dg_extra"].Value = "" + extra + "";
}
else
{
linha.Cells["dg_extra"].Value = "" + Config.rm.GetString(extra) + "";
}
DataConsole.CurrentCell = DataConsole.Rows[idLinha].Cells[0];
//DataConsole.Refresh();
}
}
catch (Exception ex)
{
throw;
}
}
}
However, the form freezes and I can't move it to any part of the screen, would there be any way to solve this? Remembering that the DataGridView is not, and cannot be populated through the DataSource property, but by a constant verification in the system.
Example:
public static void Abrir(string metodoChamador)
{
try
{
Abrir:
dgView.addLinha(2, "config_Abrir", "config_Validando", 1);
Thread.Sleep(5000);
Atalho:
string AtalhoExiste = "" + Directory.GetCurrentDirectory() + "\\" + Config.Atalho + ".lnk";
if (!File.Exists(AtalhoExiste))
{
dgView.addLinha(2, "config_FaltaIcone", "", 0);
Thread.Sleep(5000);
goto Atalho;
}
else
{
ProcessStartInfo info = new ProcessStartInfo(#"" + Directory.GetCurrentDirectory() + "\\" + Config.Atalho + ".lnk");
Process whatever = Process.Start(info);
whatever.Dispose();
Thread.Sleep(5000);
IntPtr WinHandle = Win32.FindWindow(null, Config.Atalho);
if (WinHandle == (IntPtr)0)
{
goto Abrir;
}
}
}
catch (Exception ex)
{
throw;
}
}

It's hard to tell if you have other potential problems in the code. Basically anywhere you have Thread.Sleep(), your GUI is going to freeze.
Here's a possible refactoring of your Abrir() method, using async\await and Task.Delay() as suggested by JQSOFT:
public async static void Abrir(string metodoChamador)
{
try
{
IntPtr WinHandle = IntPtr.Zero;
do
{
dgView.addLinha(2, "config_Abrir", "config_Validando", 1);
await Task.Delay(5000);
string AtalhoExiste = "" + Directory.GetCurrentDirectory() + "\\" + Config.Atalho + ".lnk";
while (!File.Exists(AtalhoExiste))
{
dgView.addLinha(2, "config_FaltaIcone", "", 0);
await Task.Delay(5000);
}
ProcessStartInfo info = new ProcessStartInfo(#"" + Directory.GetCurrentDirectory() + "\\" + Config.Atalho + ".lnk");
Process whatever = Process.Start(info);
whatever.Dispose();
await Task.Delay(5000);
WinHandle = Win32.FindWindow(null, Config.Atalho);
}
while (WinHandle.Equals(IntPtr.Zero));
}
catch (Exception ex)
{
throw;
}
}
If you have Thread.Sleep() in other locations, they would need to be refactored.
If you have any other infinite loops using goto, those may need to be refactored as well.

Running the windows service for every 5 Min

I had created a windows service & Done with successful installation.
I had observed that even though the installation was done, but the service is not showing in the list of services.msc also How could I make the service the to run for every 5 min of interval.
Worked upto the part of installation of the service.

How to fix issue of zkemkeeper.dll realtime events inside windows service?

i'm setting up windows service and want it to sync the device attendance to SQL Server database using zkemkeeper real time event. i have successfully created service as well as tested the service on my local system which run windows 10 and another one window 8 service work fine and sync the attendance record to DB server at real time. Now after successful testing on local system i deployed service over production server where service successfully established the connection with device but it didn't respond to Real time event for testing purpose i have created winform app and run it over the server and find out it is working and listening to real time event but i need service to work properly not win form application any help will be appreciated thanks below is my code !

How to use named Mutex

I'm trying to use Mutex to handle different process/application to write on same file.
This is my code
ILogTest logTest = new LogTest(new FileLog());
logTest.PerformanceTest();
public class ILogTest
{
public void PerformanceTest()
{
for (int i = 0; i < this.numberOfIterations; i++)
{
try
{
Thread threadC = Thread.CurrentThread;
threadC = new Thread(ThreadProc);
threadC.Name = i.ToString();
threadC.Start();
threadC.Suspend();
threadC.IsBackground = true;
}
catch (Exception)
{
throw new Exception("errore");
}
}
}
private void ThreadProc()
{
try
{
log.Write("Thread : " + Thread.CurrentThread.Name.ToString());
this.log.Write("Thread : " + Thread.CurrentThread.Name.ToString());
this.log.Write("Thread : " + Thread.CurrentThread.Name.ToString());
this.log.Write("Thread : " + Thread.CurrentThread.Name.ToString());
}
catch (Exception)
{
throw new Exception("errore");
}
}
}
FileLog is an implementation of ILogTest.

Trying simulate it, it doesn't write anything to file, only create it..
I don't know why.
Could anyone help me? thanks

The FileLog constructor calls rwl.WaitOne() which acquires the mutex (I'm assuming rwl is a Mutex object), but never calls rwl.ReleaseMutex().
Thus, every thread that calls Write() blocks on its call to rwl.WaitOne() because the mutex is still owned by another thread.
You will need to release the Mutex in the FileLog constructor so that other threads can acquire it.
Also, you have a call to threadC.Suspend(); in PerformanceTest; unless there is code that resumes the threads, they will never finish running.
