Secure ClickOnce Applications

Fri, 20 Nov 2009 16:09:14 GMT

I have various applications that I publish with ClickOnce using .NET Framework 2.0. I have an encrypted app.settings file, although when I first install this application the original folder created in C:\Documents and Settings\user\Local Settings\Apps\2.0\etc... is not encrypted until execution for the first time, so there is a app.settings file that is not encrypted upon installation.

How can I encrypt my app.settings in this original installation location.

Integration services doesn't run under Management Studio

Fri, 20 Nov 2009 13:58:19 GMT

Hi Lads,

I work with SQL2005 on WindowsServer 2003/R2 32bit and I'm also have admin privileges.

I can run Integration Services and design my package.

When I try to run Integration services under Management Studio, It doesn't work because I cannot select sql authentication but only windows authentication. When I try to launch with this limitation, always appears a msg that I cannot run it.

It's strange because in sql server manament I can't see the service.

What do I have to do ?

Thanks for your Help

Client not able to authenticate to server, when CA goes down

Fri, 20 Nov 2009 13:50:47 GMT

Hi,

We have an application which authenticates using the active directory credential and smartcard certificate.

But when the issuer Certificate Authority goes down, we are not able to access the particular application using the Smartcard Certificate issued by the same Sub CA, but we are successfully able to login to the application using the user’s smartcard certificate which are issued by other sub CA

What may be the reason?

Clients, application server and Sub CAs are in 1 domain
The authenticate users are in a group inside Active Directory.
The Server certificate is issued from one of the Sub CA.
we have one root ca and 2 sub ca.

Please help

Thanks!

I'm using Excel 2007 and I want to shade values in column AB if they are less than values in column W in their corresponding rows. I can do this with Conditional Formatting of course, but I would have to do this with each individual cell. How can I get around this?
Please help!

Stragen 401.3 Error

Fri, 20 Nov 2009 12:15:34 GMT

I posted this in the silverlight section earlier but On reflection I think it really belongs here:

I have a Silverlight application that needs to access a WCF web service (hosted in IIS 6.0) located on a different domain, so I create the ClientAccessPolicy.xml and stick it in the service's web site root.

What I then get is 401.3 errors when the silverlight application tries to access it.

Now here comes the funny bit, having gone over all the NTFS and IIS permissions I could think of , without success, I discovered that I could access it if I changed the extension to .svc (but not if I changed it to .html, .txt, .abc).
I could also access it if I moved it to another web site on the same server, which has as far as I can see has identical permisioning.

Is there another source of permisioning, based on file extensions, hidden away somewhere? read more

Button does not fire on first click but does on second click

Fri, 20 Nov 2009 10:47:55 GMT

My button control does not fire on 1st time click but works on 2nd click though its doing post back in both scenarios. To add little more insanity to it, this is happening only when I am calling one particular method in my click event , otherwise it works normally, but on double click its working fine. Any ideas whats going on and how this can be handled?

this is my code for it but I dont think anything is wrong with my code , its framework thats playing some tricks I guess :(

<asp:Button ID="btnEdit" runat="server" Text="Edit" onclick="btnEdit_Click" OnClientClick="return confirm('Are you sure you want to edit this message?')" />

protected void btnEdit_Click(object sender, EventArgs e)

{

CompanyAlertLogic.UpdateCompanyAlerts(ddlCompanies.SelectedItem.Text, txtShowAlert.Text);

}

Adding a group to another Group.

Fri, 20 Nov 2009 09:15:56 GMT

Hi everyone,

I'm attempting to add an existing group to another group in AD as shown below. However, I keep an exception when I attempt to do so.

I've been Googling about but I can't seem to find (if any) references to adding groups to other groups. Is this possible with .NET? Any pointers would be greatly appreciated. Thanks.

var groupPathA = "LDAP://CN=" + groupName + ",OU=ou1,DC=*****,DC=******,DC=***";
            var groupA = new DirectoryEntry(groupPathA, username, password, AuthenticationTypes.Secure);

            var grouppathB = "LDAP://CN=item,OU=ou2,OU=ou1,DC=*****,DC=*****,DC=***";
            vargroupB = new DirectoryEntry(groupPathB, username, password, AuthenticationTypes.Secure);

            group.RefreshCache();
            using (groupA)
            {
                try
                {
                     groupA.Invoke("Add", new[] { groupB.Path });
                }
                catch (Exception ex)
                {
                   Console.WriteLine(ex.ToString());
                 }

I'm using the following code to back-up and restore the database.

try

            {

                using (DataSet dSetBackup = new DataSet())
                {

                    // get the schema of the selected table from the database to restore

                    using (SqlDataAdapter dAd = new SqlDataAdapter("select * from " + tableName, conn))
                    {

                        // Following line will get the schema of the selected table in the dSetBackup DataSet

                        dAd.Fill(dSetBackup, tableName);

                        // get the data for selected table from backed up XML file

                        using (DataSet dSet = new DataSet())
                        {

                            dSet.ReadXml(Server.MapPath("~/backup/" + tableName + ".xml"));

                            // Loop through all rows of the selected table and add into dSetBackup DataSet

                            foreach (DataRow row in dSet.Tables[0].Rows)
                            {

                            // Following update command will push all added rows of dSetBackup DataSet into the database

DrawThemeTextEx on painted Windows form

Fri, 20 Nov 2009 07:17:09 GMT

Hi,

I am using DrawThemeTextEx to draw text with glow behind on a form that uses the Aero Glass effects of Vista and Win7, and it works perfectly (as per the first picture below). 

However, if I add some color to the glass using LinearGradientBrush, the text is surrounded by a transparent rectangle (as in the second picture).

Is there a way around this?

Works fine with standard blur:

Obviously not right when adding color to the glass:

I can supply the source code for anyone who can take a look.
