I have a column (data type timestamp) in SQL Server 2008.Now I want to show this timestamp value in ASP.Net C# app as string. Is there any way to do that?I tried it using regular data fetching in ASP.Net but it produced System.byte[] as output rather than actual value. In SQL Server Management Studio values are represented as 0x000000000000B3C0

on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings
'We have to convert the object to a connection string
Dim rootWebConfig As System.Configuration.Configuration
rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec")
Dim connString
As System.Configuration.ConnectionStringSettings
connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1")
Dim strConnString
As
String = connString.ToString().......
For example:
Dim testdate As String = "29/10/2010"
testdate = Convert.ToDateTime(testdate.ToString)
Response.Write(testdate)
expecting "29/10/2010 00:00:00" what I get is "29/10/2010"
If I have a string containing valid JSON
how can I convert to an obect in c#?
error cannot convert from 'object' to 'string' The best overloaded method match for 'System.IO.File.Exists(string)' has some invalid arguments
string theUserId = Session["UserID"].ToString();
OdbcConnection cn = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver}; Server=localhost; Database=gymwebsite2; User=x; Password=x;");
cn.Open();
OdbcCommand sc = new OdbcCommand(string.Format("SELECT picturepath FROM Pictures WHERE UserID ='{0}'", theUserId), cn);

I was following a MSDN walkthrough [URL] which is a very simple ASP.NET example with Visual Studio 2010:
·
I have a simple database table with a timestamp column;
·
I created a "Linq to SQL Class", and drag the table from Server Explorer onto it;
·
I dragged a LinqDataSource onto the web page and pointed it to the dbml;
·
I dragged a DetailsView onto the web page using the LinqDataSource.
·
I enabled editing on the data source.
When I run, the time stamp column is also displayed on the DetailsView as something like "AAAAAAAAB9Y=". Then, when I change the "EmployeeName" and update, I got following exception: Failed to set one or more properties on type person. Cannot convert value of parameter 'tstamp' from 'System.String' to 'System.Data.Linq.Binary'. I was strictly following the MSDN walkthrough. I tried multiple times, I even installed Visual Studio 2010 SP1 Beta. But it consistently through this exception. Can someone shed some light on this? Not a encouraging start form someone thinking to learn the lastest Microsoft stuff!

I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object.

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.

I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.

I need to load an XML document into my Dictionary<string,string> object.XML looks like:
<nodes>
<node id="123">

</node>
</nodes>
How can I do this using XmlDocument?I want readability over performance, and I find XmlReader to be hard to read b/c you have to keep checking the node type.
