show running applications (alt-tab program list)

Question

Found the solution here: http://blogs.msdn.com/b/oldnewthing/archive/2007/10/08/5351207.aspx

---

I'm trying to go a list of running applications, i found on several forums this solution:

Process[] processes = Process.GetProcesses();
foreach (var proc in processes)
{
     if (!string.IsNullOrEmpty(proc.MainWindowTitle))
        Console.WriteLine(proc.MainWindowTitle);
}

exept this is not giving me the same list as when you press alt-tab. For example: firefox, explorer, and iexplore all return an empty/null MainWindowTitle. Is there another way to access this list? Maybe thru a windowsAPI?

I'm am using Windows 7 32bit

Thank you in advanced.

Answer 1

There are no hidden processes on Windows. Only processes you do not have (security) rights to see.

have a look at the below:

Retrieve a complete processes list using C#

Try this (taken from here), but I'm not sure it solves your problem:

static void Main(string[] args)
{
    GetProcesses();
    GetApplications();
    Console.Read();
}
public static void GetProcesses()
{
    StringBuilder sb = new StringBuilder();
    ManagementClass MgmtClass = new ManagementClass("Win32_Process");

    foreach (ManagementObject mo in MgmtClass.GetInstances())           
        Console.WriteLine("Name:" + mo["Name"] + "ID:" + mo["ProcessId"]);               

    Console.WriteLine();
}

public static void GetApplications()
{
    StringBuilder sb = new StringBuilder();
    foreach (Process p in Process.GetProcesses("."))
        try
        {
            if (p.MainWindowTitle.Length > 0)
            {
                Console.WriteLine("Window Title:" + p.MainWindowTitle.ToString());
                Console.WriteLine("Process Name:" + p.ProcessName.ToString());
                Console.WriteLine("Window Handle:" + p.MainWindowHandle.ToString());
                Console.WriteLine("Memory Allocation:" + p.PrivateMemorySize64.ToString());                     
            }
        }
        catch { }
}
