Encrypt connection string in web.config file

Following code snippet will help to encrypt connection string in web.config file.


  protected void encryptConfi(bool bencrypt)
        {
            string webconfigfilepath = "~/";
            Configuration config = WebConfigurationManager.OpenWebConfiguration(webconfigfilepath);
            ConfigurationSection configsec = config.GetSection("connectionStrings");
            if (bencrypt)
            {
                configsec.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
            }
            else
            {
                configsec.SectionInformation.UnprotectSection();
            }

The Difference Between “Add Web Reference” and “Add Service Reference”


I was playing around with building a simple WCF ASP.NET client in Visual Studio 2008 and wanted to make a reference to my WCF service (that used basicHttpBinding). I have built plenty of ASMX web services in the past so simply selected “Add Web Reference” as I’d done before, pointed to my .svc file hosted in IIS, and away I went – everything worked as expected.
Then I spied the “Add Service Reference” menu option and thought – hey that’s weird I wonder what that does?
Well it’s pretty simple really.
Add Web Reference is a wrapper over wsdl.exe and can be used to create proxies for .NET 1.1 or 2.0 clients. Of course this means when you are pointing to a WCF service you have to be pointing to an endpoint that uses basicHttpBinding (as I was).
Add Service Reference is a wrapper over svcutil.exe and also creates clients proxies (and additionally web.config entries). These proxies, however, can only be consumed by .NET 3.0+ clients.

Download

Following is a snippet required to download a file


    private void StartDownloadFile(string attachmentPath)
        {
            FileInfo file = new FileInfo(attachmentPath);
            Response.Clear();
            Response.ClearHeaders();
            Response.ClearContent();
            Response.AppendHeader("Content-Disposition", "attachment; filename = " + file.Name);
            Response.AppendHeader("Content-Length", file.Length.ToString());
            Response.ContentType = "application/download";
            Response.WriteFile(file.FullName);
            Response.Flush();
            Response.Close();
            Response.End();
        }

hyperlink in template column gridview

following snippet is useful to insert hyperlink template column in grdview 

    <asp:TemplateField  HeaderText="User name">
                <ItemTemplate>
                    <asp:HyperLink runat="server" ID="lnkRedirect"  NavigateUrl='<%# String.Format("~/UserDetails.aspx?username={0}",Container.DataItem) %>' Text='<%# Container.DataItem %>'></asp:HyperLink>
                </ItemTemplate>
            </asp:TemplateField>

if you are binding arraylist to gridview & grdview contains template column then in controls text property
use Text='<%# Container.DataItem %>' instead of Text='<%# ColumnName %>' because columnName is not available in arraylist

add Serial Number in gridview

sometimes we need to add serial numbers in gridview. we can achieve it through following code

<asp:TemplateField>
            <HeaderTemplate>
            Serial No.</HeaderTemplate>
            <ItemTemplate>
            <asp:Label ID="lblSRNO" runat="server" 
                Text='<%#Container.DataItemIndex+1 %>'></asp:Label>
            </ItemTemplate>
            </asp:TemplateField>


This code works as same when we apply paging.
We cannot use this on BoundFields because they support only those objects who have Databinding event

Sending SMTP email from SQL Server using CDO

Sending SMTP email from SQL Server using CDO

exec sendMail_With_CDOMessage
'SMTP server name Or SMTP IP'
, '1'
,'25'
,'SMTP User name'
,'SMTP User Password'
,'From which email'
,'To which email'
,'Email Subject'
,'Email Body Message'
,'Email attachment from the SQL with full window path <optional>'


Make sure that your SMTP is confugure to have relay option from the sending server.
SMTP can be configure on the server itself with IIS. Or you can use external SMTP server to send email.

It is very useful when you want to send some automated message from SQL server itself based on certain task completion or failure.

You need to give grant permisions on following stored procedures. Following procedures are present in Master Database so you need to give grant permision to your user in master database.
