I am reading the sample code about the SocketAsyncEventArgs. The sample code aims at high performance by pre-allocating needed buffers. I am debugging the code to evaluate how would I inorporate the code into real projects.
Meanwhile, I would like to know if there are any existing (open source) libaries built around SocketAsyncEventArgs. If there are mature ones, I would gladly to use them to save time. Thanks for any advices.

Hi,
we use two factor authentication to access Project Online PWA.
We are looking to interrogate/integrate the PWA data with a service call.
Is there a way of creating a 'device secret' and implement it into c# code, callable from a service?
Thanks

hello, I am getting a problem while reteriving a value from dynamic variable
I have a dynamic variable of type Class it is having Properties like Name,Age etc
so how to get the value dynamic d= classObject
d.Age while Accessing these line I am getting Error
var scriptText=@"using System;
using System.Windows.Forms;
class Script
{
static void Main()
{
MessageBox.Show( "Hello World!");
}
}";
var scriptOptions = ScriptOptions.Default;
var mdr = new MetadataReference[] { MetadataReference.CreateFromFile(this.GetType().Assembly.Location),
MetadataReference.CreateFromFile(TypeExtensions.GetSystemAssemblyPathByName("System.Windows.Forms.dll")),
MetadataReference.CreateFromFile(TypeExtensions.GetSystemAssemblyPathByName("System.dll"))};
scriptOptions.AddReferences(mdr);
var script=CSharpScript.Create(scriptText, scriptOptions);
script.RunAsync();
Exception: error CS0234: The type or namespace name 'Windows' does not exist in the namespace 'System' (are you missing an assembly reference?)
I have tried scriptOptions.AddReference("System.Windows.Forms.dll") to no avail.
I have also tried css_reference System.Windows.Forms.dll;
In the debugger I can see that the metadataReferences are set directly to the correct paths for the system dlls, however it does not recognize the System.Windows namespace.
Hello!
There is any support for WSTrust STS on .Net Core ?
I want to do this in .net core:
else { binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName; ep = new EndpointAddress("https://abc.com/adfs/services/trust/13/usernamemixed"); } factory = new WSTrustChannelFactory(binding, ep); factory.TrustVersion = TrustVersion.WSTrust13; factory.Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials; var rst = new RequestSecurityToken { RequestType = RequestTypes.Issue, AppliesTo = new EndpointReference("urn:adfsmonitor"), KeyType = KeyTypes.Bearer, }; IWSTrustChannelContract channel = factory.CreateChannel(); GenericXmlSecurityToken genericToken = channel.Issue(rst) as GenericXmlSecurityToken; return genericToken.TokenXml.InnerXml.ToString();Thanks in advance

Hello, how can I get the info you see in the Computer Management Console under Local Users and Groups.
I need to be able to see a list of users and for each user the "member of" list as you would see in on this properties tab?
I would to catch if someone setup "HomeUsers" for the main account and T4CAdmin account as this causes many permission issues with our software. So if a tool is able to detect this, it would speed up troubleshooting as well as getting them to setup the PC correctly from the start.

Plz help me on this issue.

I have a System.Windows.Forms.ListView with View = Detail and SelectFullRow. I use grouping.
Consider the following scenario:
...
item A
Group Header
item B
...
Let item A be selected; when I press the down arrow selection passes to item B as expected, however the Group Header is highlighted by a dotted rectangle like the glyph indicating focus; pressing the down arrow again, the rectangle disappears but selection remains on item B. The same happens if now I press the up button.
As a result, scrolling through the list shows an annoying hysteresis when crossing the groups.
Have I missed any setting?
Dear .NET Experts,
I have looked at the definition for the file upload class (https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.webcontrols.fileupload?view=netframework-4.7.2) and wonder now,
where do I put the user information for the user (ftp) that has the right to the path directory?
I use helper tags for label and select tags like so:
<select asp-for="Article.Countries.Id"></select>
I now want to use a custom tag multiselect into which a JS library hooks into.
I now want to use the tag helper expansion from select in this new tag:
<multiselect asp-for="Article.Countries.Id"></multiselect >
What is the safest way to extend the select-helper tag to also kick in for this new tag?
Hello,
In my code (.NET Standard 2.0 Library) I'm trying to open a named pipe via NamedPipeServerStream and I can successfully consume that stream from a client process as long the Process User is the same.
But what I need is to set the security so, that all Authenticated Users can access the stream from the Client process.
e.g:
PipeSecurity ps = new PipeSecurity();
NamedPipeServerStream pipeServerStream = new NamedPipeServerStream(Globals.PIPE_NAME_ROUTER, PipeDirection.InOut, 2, PipeTransmissionMode.Message,PipeOptions.Asynchronous | PipeOptions.WriteThrough);
ps = pipeServerStream.GetAccessControl()
ps.AddAccessRule(new PipeAccessRule(new SecurityIdentifier(WellKnownSidType.AuthenticatedUserSid, null), PipeAccessRights.ReadWrite, AccessControlType.Allow));
But the following call:
pipeServerStream.SetAccessControl(ps);
will fail with an "UnauthorizedAccessException" (even if my Server Process is in "Elevated Mode").
All hints I found in the Internet (for the full framework) propose to set the PipeSecurity in the NamedPipeServerStream constructor. But this is not available under .NET Standard 2.0.
Does any workaround exist to set any access rules from within the process?

I am writing a console application that does geometric manipulations but does not attempt to draw anything on the screen.
Apparently if I want to do geometric manipulations, using classes and structs such as SizeF, PointF, etc. I need to have a heading line "using System.Drawing;" but this is not allowed in a console application. This is unfortunate because I am basing this on code from a Windows Form application.
Is there any way that I can use these in a console application? Am I missing something?
For 3 days now I've been searching the answer to this seemingly easy question.
I've created a class like so:
public class SourceMenuItem : ToolStripMenuItem
{
private string connection;
public string Conn
{
get
{
return connection;
}
set
{
connection = value;
}
}
}
My ToolStripMenuItem control is called SourceLeft System.Windows.Forms.ToolStripMenuItem
Here's how I dynamically add items
SourceMenuItem item = new SourceMenuItem();
item.Text = "drive c:";
item.Tag = "drive";
item.Conn = "my string to retrieve";
// (other stuff like ToolTipText, etc...)
SourceLeft.DropDownItems.Add(item);
And here's how I retrieve the values
string text = "";
string tag = "";
string conn = "";
int max = SourceLeft.DropDownItems.Count;
for (i = 0; i < max; ++i)
The error message for .Conn is to be expected:
ToolStripItem does not contain a definition for 'Conn' and no accessible extension method 'Conn' accepting a first argument of type 'ToolStripItem' could be found.
I'm new to C# and couldn't find the answer about the code I'm missing to make this work:
I wish to address the .Conn property the same way I do with .Text & .Tag
Thank you for all your help
Have a nice day.
