How can I retrieve X509 CERT_TRUST_STATUS with .net?

Posted By:      Posted Date: September 14, 2010    Points: 0   Category :.NET Framework
Hello I'm writing a program w/VS 2008 & C# where part of the goal is to check local machine certificates verify the certificates, collect properties and ensure they are not about to expire, etc... We were previously doing this using certutil and vbscript, and just parsing the output. However, I'd like to do this using a .net program. I have no problem opening the certificate collection using x509Certificate2collection and iterating the properties of the certificates. However, I can't seem to find where I can get the dwerrorstatus & dwinfostatus flags, which apparently resides in the CERT_TRUST_STATUS structure. I've seen many references to capicom, wincrypt, but I'd like to do it without those if possible. <http://msdn.microsoft.com/en-us/library/aa377590%28VS.85%29.aspx> This link has the info I'm looking to get. I've passed the certificate to the following: private void chainStat(X509Chain ch, X509Certificate2 x509) { ch.ChainPolicy.RevocationMode = X509RevocationMode.Online; ch.ChainPolicy.RevocationFlag = X509RevocationFlag.EntireChain; ch.ChainPolicy.UrlRetrievalTimeout = new TimeSpan(1000); ch.ChainPolicy.VerificationFlags = X509VerificationFlags.NoFlag; ch.ChainPolicy.VerificationTime = DateTime.Now; ch.Build(x509); } Assuming the info might be somewhere in ch, but I can't find it. So is there a w

How to retrieve data from SqlDataSource and pass to a variable?


Hi there,

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:

    <asp:SqlDataSource ID="sdsFormOrderDetails" runat="server" 
ConnectionString="<%$ ConnectionStrings:ForexDB %>"
ProviderName="<%$ ConnectionStrings:ForexDB.ProviderName %>"
SelectCommand="usp_GetOrderDetails" SelectCommandType="StoredProcedure"
UpdateCommand="usp_UpdateOrder" UpdateCommandType="StoredProcedure"
<asp:ControlParameter Name="orderId" ControlID="grdOrders" PropertyName="SelectedDataKey.Value" />
<asp:ControlParameter Name="orderId" ControlID="frmOrderDetails" PropertyName="SelectedValue" />

Win32 Resources: Using C++ to Programmatically Retrieve a Global Cursor's Shape and ID


Getting global cursor information is useful when developing software that drives or gathers information about other UI-based applications, including information about a remote machine. This article describes a way to programmatically identify the current cursor's ID and bitmap at any point in time. The first technique described is based on polling for information and shows how to get the handle of the current global cursor. This handle will then allow you to get information about the cursor. You can also monitor WinEvents for changes to the global cursor.

How to retrieve image from DB with Linq and diplay in Image Control


Hi all-


I'm using the file upload to let the user upload a single file.  Here's the code I'm using to then upload to the DB.  How do I reverse this process and dowload the image into the control for it to display on a different page?

Here's my code for the upload - which I think works but can't confirm until I can see the download since all I see in the DB is "binary data"

'update DB with new Image 
        If FileUpload1.HasFile AndAlso FileUpload1.PostedFile.ContentLength > 0 Then
            'Read the file in to a byte Array.
            Dim filebyte As Byte() = FileUpload1.FileBytes
            Dim fileBinary As New System.Data.Linq.Binary(filebyte)
                Dim c3 = (From c In dc.ProductImages _
                          Where c.userID = userGuid _
                          Select c).FirstOrDefault

                c3.productImage = fileBinary

            Catch ex As Exception
                Throw ex
            End Try
Here's my attempt at the retrieval, which isn't working:
                    Dim currentImage = F

RSACryptoServiceProvider + smart card with X509 certificate = Bad Key.

Hello! I'm trying the interop with Java. The task: create  SHA1withRSA signature of the document hash with .NET CLR. The singer key is an X509 certificate from external CA, and this signer certificate is on the smart card. 1. First solution: the .NET CLR SignedCms class passes the document hash to the Windows CryptoApi (and to the smart card), and the result is a PKCS#7 message with the signature. This solution works well with smart card, but the requirement is only the "SHA1withRSA" signature of document hash, the PKCS#7  message will be created at Java side. 2. Second attempt, create only "SHA1withRSA" signature:             // choosing certificate from smart card             X509Certificate2 card = GetCertificate();             // this fails when certificate is on the smart card:             RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)card.PrivateKey;             // only the signed hash needed             byte[] signedHashValue1 = rsa.SignData(documentHash, new SHA1Managed()); The problem: the car

Cannot retrieve values of dynamically generated controls

Hi All, I am creating a user control which contains checkboxes and labels that needs to be created on fly. The dynamic generation of these controls depend on the values retreived from a SPlist. I have several panels that display items queried from the list on the basis of a selection criteria. On a button click event I need to capture all the selected values from the controls that were generated dynamically.  When I traverse each dynamic control that I added to the panel, I dont see their values. I tried using recursive retrieval of the control from the page as well but it just behaves crazy, it treats a radio button as a checkbox and returns a value that I am not looking for. I am not using the the page_load() or any other event, I use the button handler on my custom method. I was thinking for ViewState, ControlsState or SessionState. I assume ViewState may not work on this as the dynamically generated controls need to be in the page_load event. Please guide as this getting way more complicated than what I had ever thought of it to be.
