This is an insane idea. You can install all sorts of backup software on your server that does what VMWare does with snapshots.

no not just disk backup - what if your box has been hacked and you don't know what it is? If I can say even restore snapshot on say monthly basis - I can have the peace of mind my system is *clean*.
I'm considering this for a site with low-medium traffic - if speed is concern then I can buy faster hardware to compensate.

You can backup your entire system with tools like Ghost, on a regular basis, and you can restore the hard drive to that state, just like a snapshot.

Its very difficult to say the reason with out your code. You are passing any parameter named workflowType which is passed as a null. So verify your code.
BTW : This is not related with ASP.NET, you need to post it over here WPF/WCF/WWF Forums

object reference is not set to an instance of an object
code i have written for registration page
bal data = new bal();
data.FirstName = Text_FirstName.Text.Trim();
data.LastName = Text_LastName.Text.Trim();
data.Gender = Text_Gender.Text.Trim();
data.EmailId = Text_EmailId.Text.Trim();

{
Page.RegisterStartupScript("SS", "<script> alert('Completed Successfully');</script>");
}
else
{
lblmessage.Text = "registration failed";
}
}
catch
{
}
i have used 3 tier architecture
the code in the dal layer for registration page
static SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ToString());
internal static int insertreg(bal bal)
{
//throw new NotImplementedException();
con.Close();
con.Open();
SqlCommand cmd = new SqlCommand("sp_reg", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@FirstName", bal.FirstName);

cmd.Parameters.AddWithValue("@YearPassedOut", bal.YearPassedOut);
cmd.Parameters.AddWithValue("@type", "i");
try
{
return cmd.ExecuteNonQuery();
}
catch
{
throw;
}
finally
{
con.Close();
cmd.Dispose();
}
}
}
code i have written for login page
protected void Button1_Click(object sender, EventArgs e)
{
loginbal data = new loginbal();
data.userid = txt_userid.Text.Trim();
data.password = txt_password.Text.Trim();
DataSet ds = new DataSet();
ds = data.getuserID();
}
}
the code in the dal layer for registration page
static SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ToString());
internal static DataSet GetUserID(loginbal loginbal)
{

This is bad practice - Don't do it.

WTF?
Exactly what exception will return ds throw? Surely the try block should go around everything, not just the last line.
You are not doing anything in the catch block other than rethrowing the exception. Remove the catch block it is not required.
Your connection is stored elsewhere. .NET does connection pooling, don't keep connection objects around, create a new one each time.

Hi,
Have you tried to debug it by setting breakpoints and stepping into the execution lines? Debug and you will definitely find the issue.

Which Exchange Server are you using ? If you are using Exchange Server 2007, Microsoft provided a web Services for that (Exchange Web Services [ EWS ] ), using that you can read mail from Exchange server.
Here is some excellent article in Code project by Brij,
Check the Exchange Server Section

I have a quick question regarding my project. I have looked for the information on the web, but was not able to find relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Praveen Kumar.R

im using java script
its working fine
but i want that this autorefreshing stops after some given time
how to do that ?
is it possible?
help me.

Use javascript setTimeout not setInterval. setTimeout will cause the page to be refreshed only once.

use cleartimeout() function.
|
|
|
|
|
hi
thanks for reply
can u please tell me how can i do postback after i use the cleartimeout()
|
|
|
|
|
I don't understand your question.
cleartimeout() is javascript function which will clear your refreshing function if you want to set timer again use settimeout().
If you just want to postback your page with javascript then use, __doPostBack() function.

Ah, the calling card of the moron. Help me, it's urgent. Google broken where you live ?
The answer is pretty common sense. You remove the script that does the auto refresh after a given number of times.
