Hi,
So I'm using WMI in .net with C# to start up a set of processes on a large number of remote machines. All is working well in my code to start up the processes and they are showing up fine both in WMI queries as well as in the taskmanagers of the target machines. However, as per the default for process invocation in WMI I cannot see the apps' windows on the desktop of the target machines. I've been searching around all morning to help find an answer to allow the windows to show up on the desktop so i can watch their progress, but the best I could find was some VB/WSH examples like the following...
Const SW_NORMAL = 1<br />
strComputer = "."<br />
strCommand = "Notepad.exe"<br />
Set objWMIService = GetObject("winmgmts:" _<br />
& "{impersonationLevel=impersonate}!\\" _<br />
& strComputer & "\root\cimv2")<br />
<br />
' Configure the Notepad process to show a window<br />
Set objStartup = objWMIService.Get("Win32_ProcessStartup")<br />
Set objConfig = objStartup.SpawnInstance_<br />
objConfig.ShowWindow = SW_NORMAL<br />
<br />
' Create Notepad process<br />
Set objProcess = objWMIService.Get("Win32_Process")<br />
intReturn = objProcess.Create _<br />
(strCommand, Null, objConfig, intProcessID)<br />
If intReturn <> 0 Then<br />
Wscript.Echo "Process could not be created." & _<br />
vbNewLine & "Command line: " & strCommand & _<br />
vbNewLine & "Return value: " & intReturn<br />
Else<br />
Wscript.Echo "Process created." & _<br />
vbNewLine & "Command line: " & strCommand & _<br />
vbNewLine & "Process ID: " & intProcessID<br />
End If
Anyone know how to allow desktop interaction for the processes?

It's impossible!
It's even documented in the Win32_Process class of the WMI docs. "For security reasons the Win32_Process.Create method cannot be used to start an interactive process remotely."
And no, there is no workaround. What kind of security would that be?

It all only half makes sense to me...so ya I can't flood someones desktop with windows or on the other hand important information, but at the same time I can start background processes that can do all kinds of malicious deeds with no user awareness...

Only if the account that created the processes has the appropriate rights to the remote machine's resources. If the remote process tries to do something it doesn't have permissions for, it gets terminated very quietly.

My PC had .NET.
For 1-2 months I did not use .NET.
Now if I select a new project template such as Windows application, ASP.NET application etc nothing happens. But if already existing project are clicked and made to run they do run.
The solution explorer do not show any project details such as name of project, files etc actually entire project tree is not shown.
Also when I select "IIS" element(in Systems & Services) from the Computer management console not a single folder, such as Default FTP site, Default web site etc, is shown.
What could be the problem?
Every thing will come to you if you have faith.

This may seem like a stupid question, but is IIS running? Is the wwwroot folder where IIS expects it to be?

The 'wwwroot' folder is at the desired location. That is not an issue.
The main thing is
1) The 'IIS' server has stopped working.
2) New .NET projects (VB C-sharp, VC++ any) can not be created.
Every thing will come to you if you have faith.

I asked if the service was running, not if it was working.
Check the Event Log to see if there are any messages specific to IIS. After that, you can start troubleshooting IIS by following these[^].

Hello i run setup wizard but before run in other pc it need frame work .net
how do it?

You might want to take a look at the Top 10 Downloads at the bottom of this[^] page. You're looking for the Redistributable for the version of the .NET Framework your app uses.

Hello,
I am drawing on a windows form using System.Drawing.Graphics. Is there a way to wire up an onclick event to certain regions of the drawing?
Thanks in advance for the insight!

No. Hit test in your Click handler to see if the cursor is in the region.

Possible Problem With Sockets 2.0 Implementation in .NET 2 with McAfee Software?
McAfee (Privacy Filter and Personal Firewall) installs it's own TCP/IP driver layer. This new driver does not seem to support sockets correctly. When attempting to connect to a remote server IPv4 TCP/IP using the Async BeginConnect you get "not supported on this object type" (unistall the Mcafee driver and it all works fine). If you do a sync connect using Connect the connection is established . However, if you then try to do an async send after connecting you don't just get an exception you get a full blown unmanaged general protection fault. This seems to be a pretty big problem has anyone else out there experienced it or maybe got a work around?

I'd guess they don't support binding to a completion port, or something like that. In the first instance complain to McAfee since their stack is at fault. It's possible that the kernel simply has a specific list of things that can bind to completion ports.
For some uses of the asynchronous pattern, .NET queues a work item to the thread pool and simply runs the synchronous version on the thread pool thread. For sockets, it's different: asynchronous I/Os are used. If the OS supports it - NT, 2000, XP, 2003 and successors - the socket is bound to a completion port which is a highly scalable way of receiving I/O completion notifications; otherwise it uses overlapped I/Os. In any case, the notification that the I/O is complete ends up on the thread pool, which then calls your callback function.
.NET 2.0 adds a new property to the Socket class which can be used to force the overlapped I/O mechanism and turn off the completion port feature: UseOnlyOverlappedIO. Set to true to stop it using the completion port. This may work around the problem, but McAfee really should fix it - .NET 1.x will always use the completion port if it's available.
Stability. What an interesting concept. -- Chris Maunder

Thanks for your help, I tried enabling the UseOnlyOverlappedIO property on the Socket but it did not seem to have any impact. When the BeginConnect is executed I still receive the error "The attempted operation is not supported for the type of object referenced". If I remove McAfee this line works fine. Below is a code snippet in case I am missing something. I have raised this with McAfee and Microsoft but I suspect it's going to be a case of bug ping pong for a while.
ipendRemote = new IPEndPoint(Dns.GetHostEntry(m_sHost).AddressList[0], m_iPort);<br />
m_sockDestination = new Socket(ipendRemote.AddressFamily, SocketType.Stream, ProtocolType.Tcp);<br />
<br />
m_sockDestination.UseOnlyOverlappedIO = true;<br />
<br />
m_sockDestination.BeginConnect(ipendRemote, new AsyncCallback(this.OnConnected), m_sockDestination);

I've just seen a blog post[^] by the Windows Networking development team talking about how Layered Service Providers behave with a mix of different sockets. This might have some impact on your problem, I'm not sure.
If you're still having the problem, you could try posting a comment to that blog entry.

Hi to all,
How to run an exe of a code written in .Net Framework, on an PC without having installed .Net on it?
Thanks & Best Regards,
Aniket Salunkhe

Basically, you can't. Without the .NET Framework, none of the classes that you are using in your code exist and, therefore, the code won't run. You have to install the framework.

Create a deployment project by selecting: File/New/Project/Other project types/Setup and Deployment
From here you can use the wizard or just select the setup type. You can make a requirement that the target have the framework installed. If it does not, then it you can select it to go out the internet and download or you can provide the file in your deployment. You can download the dotnetfx.exe (.Net Framework 2.0 Redist) from the Microsoft downloads site.

I have one vb.net windows application with one form; this is a small utility program. This Zip the content of the specific folder in a certain interval and copy the content in to some other place & keep the folder empty always. While running the application this sits in System tray as icon. This runs in the server always (24 X 7). This application I want to run as a windows service, because when ever server gets restarted, I have to run this application manually.
I tried to put this in windows service, it's running, but my problem is, I don't know how to launch the system try icon while running the service. I want once the service starts; my utility exe icon should come in system tray. Help me out in this.
Thanks,
Rajasekaran.

Add a Notify Icon control to your service or VB form. This Notify Icon with sit on System Tray. Handle certain click events with this control.
If necessary, and a Context Menu control in association with the Notify Icon. Add as many Menu Items as you wish. Handle a click event with each Menu Item.
Best,
Jun
