you can get the list of names from db or by using entity framework in controller action method so save it in a viewbag and using foreach loop display it in view using razor in a select list. After that using select change of jquery you can raise post ajax call with the changed item. by using it get the complete details of the person and return it to the view and display it in the labels using success function of the ajax call. I hope I am clear. It works for sure

I am targeting v8.0.
The only solutions I can find is; add a reference to windows runtime, but so far as I know I have done that.
What am I missing or doing wrong?

I see that this has been gathering dust for a few days, so I'm sorry if I'm too late to the party to help you.
foreach (DeviceInformation di in await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(BluetoothLEDevice.GetDeviceSelector()))
This is a problem. basically you're attempting to iterate a collection of promises, but without a custom iterator the compiler has no idea what to do with those promises.
The easy fix is to move the asynch resolution to a variable and await it, like so:
...
var myArray = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(BluetoothLEDevice.GetDeviceSelector());
foreach(DeviceInformation di in myArray)
...
Alternatively, you can abuse some of the async functionality in LINQ (I haven't validated this block, so it might need tweaking):
var result = await Task.WhenAll(Windows.Devices.Enumeration.DeviceInformation
.FindAllAsync(BluetoothLEDevice.GetDeviceSelector())
.Select(async x => await BluetoothLEDevice.FromIdAsync(x.Id)).ToArray());
result.Select(x => listView1.Items.Add(x.Name));
There are plenty of other ways to skin this cat, should you happen to like cat skins. Both of these approaches should work, though.

Hi,
I have installed Microsoft SMTP server in IIS of Windows Server 2012. When i have given Windows Integrated Security in Outbound security. The mail messages are stuck in outgoing queue of smtp server (in C:\inetpub\mailroot\Queue).
If i use anonymous authentication or basic authentication, the mail server is just working fine.
Anyone suggest what could be the possible reason for this?

The following features must be supported:
1. Fast drawing of many(more that 10-100k) single points and small lines.
2. Fast drawing of several (up to 10-100) images with high resolution(~1500x1000), which can be
a) partially out of view
b) all images in view at the same time scaled to small size
c) all in view with big size having transparency
3. Graphic control should be able to take only part of Windows Form (because UI is written using DevExpress)
Currently my choices are OpenTK and MonoGame, but I'm not sure they can do all this easily.

They should be able to cope with what you're after better than using GDI+ (the default for Windows Forms). I would suggest that you might want to start off with a quick prototype application to see if it fits your needs. As for integrating with Windows Forms, have a read of this[^].

Unity3D "may" be easier than MonoGame; MonoGame is more low-level.
Does that make Unity3D slower? Don't know; would check it out.

How can I use the CreateProcessAsUser or LogonUser when staring the process:
Dim ps As New System.Diagnostics.Process
ps.StartInfo.UseShellExecute = False
ps.StartInfo.Domain = Domain
ps.StartInfo.UserName = UserName
Dim pword As New System.Security.SecureString()
For Each c As Char In Password
pword.AppendChar(c)
Next
ps.StartInfo.Password = pword
ps.StartInfo.LoadUserProfile = False
ps.StartInfo.WorkingDirectory = ApplicationWorkingDir
ps.StartInfo.FileName = "cmd.exe"
ps.StartInfo.Verb = "runas"
If BatchSize = String.Empty Then
ps.StartInfo.Arguments = "/c bcp " + DbTable + " in " + SourceFile + " -m " + MaxErrors + " -f " & FMTFile & " -e " & ErrorFile & " -o " & LogFile & " -S " & ServerName & " -T "
Else
ps.StartInfo.Arguments = "/c bcp " + DbTable + " in " + SourceFile + " -m " + MaxErrors + " -f " & FMTFile & " -b" & BatchSize & " -e " & ErrorFile & " -o " & LogFile & " -S " & ServerName & " -T"
End If
ps.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
ps.Start()
ps.WaitForExit()

What kind of app are you writing and where is this process being started?
Is this a Windows Forms app, console app, WPF, Windows Service, ASP.NET, ... ??
Is the process being created locally, meaning on the same machine as the code you've shown or is it being created on a remote machine?
....and you STILL do not have to run CMD and do not need the "RunAs" verb line. It's nice to see you don't listen to the answers you've been given.

it's a console application running on a server from a scheduler.
I need to start a process as specific user with access to cmd.exe and pass userID in my process

The default task scheduler[^] contains options to run your app under another account. So, I assume you are not using that task-scheduler?
byka wrote: I need to start a process as specific user with access to cmd.exe and pass

You mean that it should display a console-window where the user can execute additional commands?
You don't need to start CMD just to execute an application that you would normally start using the CMD-prompt.

Maybe this explanation will help :
scheduler running under user account with no permission to C: drive.
Application account should have some permission to C:drive in order to access cmd.exe
I need to add code ( CreateProcessAsUser or LogonUser) for application user in order to call cmd.exe

OK, this is a bit better but there's still lots of detail missing.
You're writing the scheduler app? Is this written as a standard console or Windows Forms application or is it a service?
Does the application this scheduler is launching have to show up as a window that the user can type in?
Why must you call CMD instead of just launching BCP directly?

You're writing the scheduler app? - Yes
Is this written as a standard console or Windows Forms application or is it a service? - Consolse application
Does the application this scheduler is launching have to show up as a window that the user can type in? - No
Why must you call CMD instead of just launching BCP directly?- you mean call bcp.exe instead of cmd?

Yes

That's not an answer to the question.
WHY do you think you must call CMD instead of just launching BCP directly?

byka wrote: Maybe this explanation will help
An answer to the question would have helped too. Are you or are you not using the default task scheduler? If yes, simply define the account you want to run under in the settings.
byka wrote: scheduler running under user account with no permission to C: drive.
Application account should have some permission to C:drive in order to access
cmd.exe
..sounds safer to give the user the permissions he/she actually needs. The user you are impersonating prolly has some more priviliges than just "cmd.exe".

If you're using the default task scheduler, supply credentials that have appropriate permissions.
If you've baked your own task scheduler, run it as a service, using credentials that have appropriate permissions.
Either way, the wheel, axle, transmission, and engine have already been invented. You just need to paint the car.

Hello! I'm using vb.net in SharpDevelop 4.4. I tryed import AvalonEdit(WPF Text Editor) in my project. But i can not do.
Error Message is :"The assembly ISHarpCode.AvalonEdit, Verison=4.4.42.9749 Culture=neutral, Publickey Token=9cc39be672370310 does not contain any components."
Thank you for help.

That suggests that the file is corrupt. Try downloading it again, or check the AvalonEdit website.
