Jeff Atwood has a good post on ways to pass email spam filters in his post at:[URL]
The only issue I have is figuring out a way to sign the email with a private key for DKIM. We use the MailMessage and SmtpClient objects that come with ASP.NET 3.5. How can I sign an email with these objects?
Also, we use the free SMTP Server that comes with Windows 2008 R2. I don't believe there is a way to sign from that server, if there is way I'm open to using that approach.
We are having issues with emails being sent to places like Yahoo that if you do not sign your emails with DomainKey they do not even put in spam folder. Has anyone had any experience with this and have advice on how we can do this? Does it work?
I have the code above, if after half of the emails were sent out, there is a error in smtp, then how can I avoid resending emails or missing emails in this cases ?
I am able to get a token with Windows Live Delegate Authentication samples provided by Microsoft.
Now I want to access emails (New, Read, Unread etc) from live account. How can I achieve it with the help of Windows Live Delegate Authentication? Are there any examples for the same?
The Samples given by Microsoft are not related to emails.
if a class has a private constructor then it cant be instantiated. so, if i dont want my class to be instantiated and still use it, then i can make it static. what is the use of a private constructor? Also its used in singleton class, except that, is there any othe use ? (Note : The reason i am excuding the singleton case above is because I dont understand why do we need a singleton at all ? when there is a static class availble.
Can it handle mapping using private members like NHibernate can? The documentation is very slim, but it seems like one of the objects or methods provided with the tool could do something like this.
I have an web application that encrypts data using a public and sent it to another web application. Which will then decrypt the data using a the user private key. My question is, since but the Private and Public key are generated in the first application. how does the other application get the private?
private void Form1_Load(System.Object sender, System.EventArgs e) { Dim stri As String stri ="SELECT allowType fROM SLABS order by allowtype" this.FillCombo(stri, Cmballowa); } private void FillCombo(string ssql, object cbo) { SqlDataAdapter da = default(SqlDataAdapter); SqlConnection con = new SqlConnection(); DataSet ds = null; DataView dv = null; con = new SqlConnection(constr); da = new SqlDataAdapter(ssql, con); ds = new DataSet(); da.Fill(ds, "ITEM"); dv = ds.Tables("ITEM").DefaultView; cbo.DataSource = dv; }
But here some error message is coming in "private FillCombo function" like "'object' does not contain a definition for 'DataSource' and no extension method 'DataSource' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)" So, how can i correct this error?
I am storing a key pair in Windows Store, and recently started receiving the "Keyset does not exist" error. Investigating a bit further i found out it could be two things, 1 - The private key is not stored with the persist key set attribute (X509KeyStorageFlags.PersistKeySet) and 2 - access rights to the key. I have tried both 1 and 2 with no success on one machine (in my machine it works apparently). The strange thing is that when i look into MicrosoftCryptoRSAMachineKeys (and S-1-5-18) the key remains there but only for a period of time then it is deleted which means that it is not persisting.
//If decoded then save as RSACryptoServiceProvider newCert.PrivateKey = DecodePrivateKey(privateKeyFile, pkPassword) if (newCert.PrivateKey == null) throw new System.NullReferenceException("Decoded private key resulted in a null reference. Unable to store certificate."); byte[] pfx = newCert.Export(X509ContentType.Pfx); newCert = new X509Certificate2(pfx, string.Empty, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet);
I am running this code on a WCF Service hosted on IIS, and the certificate is deleted even if i give permissions to Network Service, the AppPoolIdentity, my account, etc through MMC-CertMgr. Would anyone know why this happens?
how can I get the private ip of client system from a website hosted on public ip in ASP.Net C#? while i am checking userhostname, it's showing the global IP of the Internet connectivity which is the same for all the machines in the network.
I want to use PKI public and private encryption for authentication to allow for a more streamlined and secure application access control system. generation of certificate and authentication will be useful. One more question, can i use System.Security.Cryptography.X509Certificates class for the same?
I have an ASP.NET application that accesses private key in a certificate in the certificates store. On Windows Server 2003 I was able to use winhttpcertcfg.exe to give private key access to the NETWORK SERVICE account. How do I give permissions to access a Private Key in a certificate in the certificate store (Local ComputerPersonal) on a Windows Server 2008 R2 in an IIS 7.5 website? I've tried giving Full Trust access to "Everyone", "IIS AppPoolDefaultAppPool", "IIS_IUSRS", and everyother security account I could find using the Certificates MMC (Server 2008 R2). However the below code demonstrates that the code does not have access to the Private Key of a certificate that was imported with the private key. The code instead throws and error everytime the private key property is accessed.
I'm working on a page with two sets of collapsable panels. using nHibernate) I get category objects with a list of items in them, and for each category generate a left panel and right panel. In both panels, there is a ListBox. Items are pre-populated to the left list box and the user can select and move items into the right list box (under the corresponding category.) As I've built and worked on it, I ended up with a lot of generic methods like buildPanel(side,categoryID) and then ended up with a lot of repeated if statements inside them to differentiate between the two sides
if type=PanelType.Left then set these 5 id strings to access components else ...
The code got messy, so I moved a lot of the logic and static builder strings for the component ids into a private helper class in order to make other parts of the main class easier to read and follow. The problem I see is that the private class is extremely dependant on specific structures in the parent class. There's a very minimal amount of encapsulation going on and I'm possibly making the logic harder to follow even if the individual components in the code are easier to read.
My question is: When you're using a private class like this, is it acceptable to have it tightly integrated with the parent class (since it's private and implemented in the same file), am I better to refactor again and find a way of either simplifying my original code to be as short as possible without the helper class (stick all category/panel functions in one spot and hide them in their own region when I'm not using them), or should I move towards putting more of the logic in the helper class and simply mapping my events directly to the subclass. After typing all this out, I'm leaning towards the last option, but I'm still torn/confused about the whole thing...
I want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.
How can I achieve this using reflection? Is there anyother way to achieve this?
This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll") assembly = System.Reflection.Assembly.LoadFile(assemblyName) assembly.GetType("myClass").Getmethods(Bindings.NonPublic) assembly.GetType("myClass").GetMethods(BindingFlags.NonPublic) isn't working
Does anyone know ...best reliable windows Virtual Private Server providers for reasonable price?I m currently with Godaddy and I m not happy with their customer support.
Let's say in ASP.NET you have a base page class which defines a private Page_Load method which handles Page.Load. All aspx pages in your project inherit from this base page class. In this case the aspx pages would be able to call this private method. However it does not feel right that private methods can be called outside its own class? If so, privates methods cannot be hidden from outside?
I am part of a team that is developing a SharePoint web part. My task is to create a user control which will ultimately be wrapped in another class for presentation in a web part. Because of these requirements, I must fit all of my code in a single user control.To organize my code in the code-behind, I created a few private classes for the different objects which are represented in the database. I want to add some exception handling whereby if some sort of DB exception is thrown I can update a message on the page informing the user of the problem.
My problem is that the page-level controls are inaccessible from the private class where I'm issuing the query, so even if I catch the exception I have no way of directly accessing a Label control to populate the error. I tried to create a baseclass with an EventHandler defined, but when I throw events from the private class I'm not able to catch them for whatever reason. I'm far from an OOP expert Here is a snippet: ASP Code: using System; using System.Collections; [code]....
I want to know how I can make website available in my private home network? I know I am supposed to make my IP address static but I still do not know the complete steps to accomplish what I want to do. Is this even possible? If it is can someone please explain to me what I have to do?
