Change edmx model connectionstring dynamically in class library (Data Access Layer)

// Specify the provider name, server and database.
string providerName = “System.Data.SqlClient”;
string serverName = “.”;
string databaseName = “AdventureWorks”;

// Initialize the connection string builder for the
// underlying provider.
SqlConnectionStringBuilder sqlBuilder =
new SqlConnectionStringBuilder();

// Set the properties for the data source.
sqlBuilder.DataSource = serverName;
sqlBuilder.InitialCatalog = databaseName;
sqlBuilder.IntegratedSecurity = true;

// Build the SqlConnection connection string.
string providerString = sqlBuilder.ToString();

// Initialize the EntityConnectionStringBuilder.
EntityConnectionStringBuilder entityBuilder =
new EntityConnectionStringBuilder();

//Set the provider name.
entityBuilder.Provider = providerName;

// Set the provider-specific connection string.
entityBuilder.ProviderConnectionString = providerString;

// Set the Metadata location.
entityBuilder.Metadata = @”res://*/AdventureWorksModel.csdl|
res://*/AdventureWorksModel.ssdl|
res://*/AdventureWorksModel.msl”;
Console.WriteLine(entityBuilder.ToString());

using (EntityConnection conn =
new EntityConnection(entityBuilder.ToString()))
{
conn.Open();
Console.WriteLine(“Just testing the connection.”);
conn.Close();

IPhone application are growing in the market. In this example, I will give you a simple tips that how to detect request is coming from iPhone in ASP.NET application. When ASP.NET page is requested at runtime, the information in the request header to determine what type of browser has made the request by the user agent. In this example, you will see that if the request will come from iPhone then we can do what we have required for our application and if request will not from iPhone then we don’t need to do anything.

Here’s an example

protected bool isAgent()
{
if (HttpContext.Current.Request.UserAgent.ToLower().Contains(“iphone”))
return true;
return false;
}

protected void Page_Load(object sender, EventArgs e)
{
if (isAgent())
{
Response.Write(“iPhone Detected”);// what ever you do
}
}

Calculate duration of time in crystal reports

≈ Comments Off on Calculate duration of time in crystal reports

Create one formula field give name “tot_seconds”

local stringvar array completetime;
local numbervar totalseconds;

if({dtAttendance.Time}”N/A”) Then
(
completetime:=split({dtAttendance.Time},”:”);
totalseconds:= ((3600*cdbl(completetime[1])) + (60*cdbl(completetime[2]))+(cdbl(“00”)));
)

{dtAttendance.Time} time is a report field which is display time in report.

If Check In times agains chechout time not found then display ‘N/A’ and vice versa so that we haven’t calculate that time in total therefore i have to put if condition regarding this.

Now, create another formula field “totalTime”, paste below code in “edit formula” section.

WhilePrintingRecords;
NumberVar TotalSec := sum({@tot_seconds},{dtAttendance.Name});

NumberVar Hours := Truncate ( TotalSec / 3600);
NumberVar Minutes := Truncate (Remainder ( TotalSec,3600) / 60);

Totext ( Hours, ‘####’) + ‘:’+
Totext ( Minutes,’00’)

If you are putting “totalTime” field into grouo section it will display group wise total.
