You can install certificate into certificate store using Wizard in certmgr.msc (Right click install)? Does anyone knows how to "cleanly" remove all the certificate by either using wizard/Code (pref.) /Script ?
I want to be able to remove everything (that I have installed earlier) from the LocalMachine and/or CurrentUser Store without leaving any residue.
I went to load an app I was working on before my system died a few days back and I loaded up VB Express 2010 .Net, opened my project and saw this error ...
Error1Unable to find manifest signing certificate in the certificate store.HexHelperProject
If this is related to the Security Certificates stored by XP, then I'm in trouble as they are GONE. Must I start a new project and rebuild this whole app?
I am having an issue getting the below error. This error is in a small mail app using smtpClient. I had this working on this same computer but had to reformat and now I am getting the error.

Suppose I have an interface IFoo with implementation classes VideoFoo, AudioFoo, and TextFoo. Suppose further that I cannot modify any of that code. Suppose that I would then like to write a function that acts differently based on the runtime type of IFoo, such as

Then I have to do my "If TypeOf ... Is" again. How can I refactor this to take advantage of the polymorphism of the implementations of IFoo without manually checking the types? (in VB.NET, though my question applies to C# too)
I noticed that when the app closed the icon remained on the taskbar until the mouse was hovered over it, so added this:-
If Not AlarmClockNotify Is Nothing Then
AlarmClockNotify.Dispose()
End If
.. and that did the job.
Then I noticed that if the balloon was showing at the time the app was closed, the icon went - but the balloon stayed, so added this:-
If Not AlarmClockNotify Is Nothing Then
AlarmClockNotify.Visible = False
AlarmClockNotify.Visible = True
AlarmClockNotify.Dispose()
End If
and everything worked fine until the app was closed WITHOUT the icon showing (only dislays if an alarm is pending in the next x days) - then it throws and 'object reference not set to an instance of an object' - odd because it passed straight through the 'not is nothing' If statement.
Hi. I have 2 toolbars and want to show only one at a time.
But when I swap them using .visible, it updates the form each time I switch one on/off, so it's all flickery and slow, and other controls resize to suit the indermediate state.
How can I do it cleanly?
I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

We have somewhat bureaucratic way of making new users to our system. I noticed I had to write same info over and over again to different places (such as AD and our databases). So I desided to make a little application that inserts the info to all the right places with one click. Now I can create new user with one form and push of a button except the client certificate. For that I must login to our certserv and fill in a form.
Is there an easy way to make client sertificate request to the certserv so that it would give me the certificate automatically? I tried to google about it and got some info about the system.security.cryptography, but got stuck before getting any near of requesting new certificate.
I am trying to get OpenSSL.net to 1) create a key pair to use for CA signing and 2) create and sign certificates using this CA. I have managed to create an RSA/SHA1 X509CertificateAuthority, and have created a X509Request and keys, but I am running into problems actually signing the request.

How can protect my library with certificate?
I mean, My project is library based. So one very important dll should be under my control. I have to create a certificate for this dll. this certificate will be date wise. with expiry date. to run that project, the user must run the certificate.
how can i control it.
I am loading a certificate from string like this:
public static void Test()
{
byte[] arrayCertificate;
[Code]....
But this certificate doesn't have a "Subject Unique Identifier" Take a look at this:
[URL] (The part of Structure of a certificate)
And I want to know how can I read that value from my .NET code (I looked that I can get SerialNumber, Thumbprints and others but there is no Subject UID anywhere).
If anyone can share an openssl command to include this UID for the certificate :-) (pfx one)
I try to run my Authenticode signed app on a clean Vista PC (not internet connection available ever). I have a look in Internet Explorer if the root certificate (Trustcenter) is there, and it is not. I get the message that the reference could not be resolved, and when I click file properties and have a look at the certificate, it says "The certificate for the signature could not be confirmed". Is that a normal behaviour? I mean does the computer need to have the root certificate from Trustcenter installed?

I am totally "out to lunch." I have no clue of what this is about and cannot find anything in my references which address it. I have found no code on line that enlightens me. Is there a simple explanation and/or fix? Where can I learn more in order to avoid this in the future?
Is there a collection or property somewhere to determine the certificate properties that is in used with the current browser?
If I right-click on the browser object on the VB form, I can see the properties and see the certificates, etc. But is there a way to programatically get to that point? Not seeing anything clearly marked. Not sure if it isn't exposed or if I'm just not seeing it.
I have an application that was deployed almost a year ago using clickonce. My Test certificate is about to expire. Seemed to have read somewhere that the problem was fixed in VS 2008. Can someone confirm and tell me if there is something I have to do to keep my users up and running? Also, if I make changes to the application and redeploy after the expire date, is there anything I need to do? I don't know anything about certificates just that I had to create one to use ClickOnce.

View 1 RepliesGreetings, I am trying to install a certificate from a .p12 file into the Local Machine - Personal store and set the permissions for Everyone to full control. I can acheive this manually with mmc on W7 (or mmc + WSE Certificate Tool on XP.) When attempting with the vb.net code below I get no errors but when I try to access the security tab (Manage Private Keys in mmc on W7, or WSE Certificate Tools on XP) I get the error, "No keys found for certificate!"
I am using the following code to install the certificate, which seems to be working. However I am not convinced its placing the private key in the correct place. I have tried two methods for setting permissions on the private key and the second method, which locates the private key file indicates the private key is being stored under usersmy-user-account... Should that be a public account

I need a regular expression that will pull 7 digit certificate numbers from a file. The numbers follow the word CERTIFICATE. There could be spaces between CERTIFICATE and the number and there could not be. Here is what I have so far, but it doesn't match if there are no spaces or just one space.
