You don't need to download anything, or reference anything. Just copy user32.dll into your executable directory.

That was the first thing I tried and since that didn't work I downloaded the PInvoke.net.

Well, I'm stumped. Clearly this is related to the mobile device. I have never personally written anything for a mobile device, so I don't know what else to tell you. Hopefully someone else from the forum can help, or you can find some information through google on how to code against common windows dll's in a mobile environment. Sorry I can't do more for you, but be sure to post the answer if you find it so others can benefit (and so we can help the next guy with the same question).

Thanks Jeff for all your help. I will surely post the answer when I find it. I think so too that it is related to mobile device. I think the user32.dll doesn't get deployed on the mobile when the rest of the code does and hence it not able to find the method.
Thanks,
Ashoo

There should be a property of the DataGrid called DataKeyField. Try setting this to the employee id and see if that works.

I am trying to develop an application using Windows Forms to have streaming IO such as would be used with Console.OpenStandardInput.
I want to be able to retrieve data from a Windows form in the same manner as using "Console.OpenStandardInput". Is there a way to do this!?

Your post doesn't make sense. The example for Consol.OpenStandardInput has the application reading the keyboard input from the console window. You state you want to retrieve data from the application not read it into the application.
I think you need to clarify your requirements if we have any chance of helping you. Also before doing that perhaps you might read this[^] as it might help your messaging attempts.

I will be giving a colleague training in C#, and would like to offer it in the form of a series of one day courses. I would like to cover beginners and intermediate level practical, real world, programming in, say, four courses, and I would like some input on my syllabus. So far I see language basics, and common tasks, e.g. basic data access, in course #1; collections and .NET classes, and Windows Forms essentials in course #2; component design and implementation, interfaces, inheritance, generics, reflection etc. in course #3; and course #4 as a guided practical project, of nature still to be determined.

Have you tried just doing a ping on all the client instances, you know, just to see if they are running?

yeah... i tried
actually i tested like braodcasting 1-100 numbers
@ client side i receives like Client A receives -> 1 3 4 5 10 11 12 (missing ...)
Client B receives -> 1 2 3 4 7 8 15 16 (missing ...)
Client C receives -> 4 5 6 10 11 12 15 (missing ...)
so thats what im wondering if sockets are useless though connection is "TCP"

Hi everyone
My apologies if this has been asked before, I suspect it may have but does anyone know of any tutorials for C# ListBox drag and drop in which you are simply dragging FROM a ListBox to an external program such as simply Windows Explorer?
All the tutorials I seem to find are regarding making controls accept drag events.
Regards and thanks in advance.

You should be able to do the following:
...
using System.Windows.Forms;
...
private ListBox lb;
...
private void SomeEvent(object sender, EventArgs e) {
object data = ...; // set this to be the data you want to be dragged
// note that the data MUST be a type recognized by the system
// for it to be able to be dropped onto the desktop (like a file)
DragDropEffects result = lb.DoDragDrop(data, DragDropEffects.All);
// Do some stuff based on whether the result is move, copy, etc.
}
Hope this helps!
Jeff

Hi
The ListBox I am using contains a list of FileInfo objects.
Are these translatable to the desktop or external application?
Regards

Oh and If so how do you perform the actual act of copying?

Hi
The first link you posted I had found today and I've managed to get the code working! Meant to post up here a link but thank you for this.
The second is very useful and great thanks to you for this. My aim for the application is to drag from my application to an external application and such I can imagine the file descriptor being a problem. The tutorial on this section may be able to help with some of the problems that might arise!
Thanks again Jeff

Hi experts,
I wanted to create a multi threaded windows service, can anyone reply me with the code, i will appreciate it.
The scenario is, i have multiple databases, and i have to connect to each database and do some work after each interval using windows service.
I could not able to find a simple multi threaded windows service code sample anywhere 
Help needed, thanks,
Vijay

I would be surprised if anyone would be able to post code for this type of request. I have written a few multithreaded services and can give you some pointers.
1. I usually put all of the code used by the thread in its own DLL, that way you can basically insantiate an instance of you class for each thread and limit the race conditions which can occur between threads.
2. Create a single public method in your class which can be the starting point for your thread, populate class properties with initial values in the Service code then use the ThreadStart or ParameterizedThreadStart methods to start the thread. Once the Thread has started (you can use ManualResetEvents to monitor this) add the Thread instance to an array in the Service code so all of the running threads canbe managed from the service. Doing so will allow you to stop the threads in the event that the service must stop.
3. I've found that .NET remoting is especiall handy with M-threaded Windows Services for sending control / command requests to the threads.
Here is an example of starting a thread:
try
{
m_ThreadStarted.Reset();
Thread ADTThread = new Thread(new ParameterizedThreadStart(ProcessADTThread));
ADTThread.IsBackground = true;
m_MasterThreadList.Add(ADTThread);
ADTThread.Start(DR);
m_ThreadStarted.WaitOne(-1, false);
Lines.Append(DR["ClientName"].ToString() + " Started\r\n");
}
catch (Exception Err)
{
m_ServiceLog.WriteEntry("Start Service WaitEvent Exception: " + Err.Message, EventLogEntryType.Error);
}

hi all,
is there a limitation of client-server .net socket application that when we broadcast message from server to all connected clients, not all the clients receive it. The condition is we are receiving real time data .
is it a limitation or i'm doing something wrong... any idea?
thanks

Do all of the clients have the same firewall and configuration running?

yup.
actually all the client's instances are on same machine while server is on other machine

Most routers kill network broadcasts. For guaranteed receipt use TCP/IP and send to each client individually.
