Dear Jacob Klint
May you please tell me how to sign the volume meter you have created and implemented in my project? I got the demo project but that doesn't show how it is implemented and the source code for the demo is not available. After all the progressbar is not signed therefore gives a lot of problem using it. Please help me.

In earlier, you'd have had to disassemble Excel to parse its format, but that's long gone in databse world -with very few exceptions-.
You've got two ways:
1- The easy -most effecient- way is to export your data to an intermediary format that could be understood by most Database engines -including Excel-. For example Xml or Html files, or comma/tab delimited text files.
2- The hard way -and I wouldn't know why would anybody go there anymore. There could be some good reasons that I don'y know of though-, is to use Excel Interop -which presumes that MS Excel is already installed on the user's machine. You'd find more derails about this way in Office Interop library documentaion.

There is a third party library available somewhere called RKLib.ExportData that can export straight to .xls, but the previouse reply was right, doing csv or xml is easier and more flexible.

Hello Friends
Can someone help me.
I know how to read value using SqlHelper.ExecuteReader using storedProcedure.
But if stored Procedure has a output parameter, I'm not able to read output parameter value.
How to read output parameter value.
I could read output parameter value using SqlHelper.ExecuteNonQuery, but then I'm not able
to read database query column values.
how to read database query column values.
pls help soon

Create a paramter object, set the direction to output and add it to the command object (but keep the reference to the parameter object). After you have closed the data reader, you can access the output value in the parameter object.

Thanks for ur reply
In case of ExecuteReader:-
My stored procedure contains two result set
The actual format of stored procedure is
***************************Stored Procedure start*************************************
declare @colid1 int
declare @col2 uniqueidentifire
declare @Status out
set @col1 = "001"
set @col2 = "{123456789}"
declare @id int
select @id = (select id from tableid where colid = @colid1)
Select col1,col2,col3,col4 from tabel where col1 = @colid1 and col2= @col2
if (exists(select col1,col2 from table2 where col1 = @col1 and col2 = @colid))
{
@Status = 1
}
else
{
@Status =0
}
select @Status as status
*****************************Stored Procedure End****************************************
The above stored procedure is given for reference.
Now my problem is
I'm able to retreive column values using ExecuteReader by passing stored procedure properly
ReaderObj = SqlHelper.ExecuteReader(Pass parameters)
ReaderObj retreives only table1 columns values.......now how to read @Status value(look at above stored procedure)
*****************************************************
arParams[0] = new SqlParameter("@prref",SqlDbType.VarChar,20);
arParams[0].Value = strPrjRef;
arParams[1] = new SqlParameter("@userid",SqlDbType.UniqueIdentifier);
arParams[1].Value = new Guid("{7126886d-2538-429c-ab3c-22b3341dcecf}");
arParams[2] = new SqlParameter("@STATUS", SqlDbType.Int);
arParams[2].Direction = ParameterDirection.Output;
RdPrjDetails = SqlHelper.ExecuteReaderconnstr,CommandType.StoredProcedure, "GET_PROJECT_DETAILS_SP", arParams);
*******************************************************

Ok, so you are not using an output parameter at all?
It's a bit hard to tell, as the stored procedure that you show is lacking the entire declaration part. It's hard to say what parameters you should use in the calling code if you don't show what parameters the stored procedure uses.
Also the stored procedure contains some errors that tells me that this is not the code that you are actually using. If you only show me some made up code, I can only give advice on that code, not on the code that you are actually using.
It's like if you went to your car mechanic and said: "I've brough my bike. Can you take a look at it and tell me what's wrong with my car?" 
If you have a query that returns more than one result, use the NextResult method of the data reader to move from the first result to the next.

ok I'm giving u actual stored procedure, earlier stored procedure was given only for reference
The original stored procedure (working perfectly without error) is
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS OFF
GO

begin
declare @prjid int
select @prjid = (select PRID from EET_PROJECTS where PRREF = @prref)

BEGIN
Select P.PRID as PRID,

else 'No'
end as USECUSTPRICE,

where PRID = @prjid
END
if (exists(select opuserid, opprjid from EET_MY_PROJECTS_LISTS where opuserid = @userid and opprjid = @prjid))
begin
SET @STATUS = 1
end
else
SET @STATUS = 0
select @STATUS as status
end
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
Now u able to understand what is the actual problem.
Thanks in advance

That's better, that stored procedure actually has an output parameter.
Why are you returning the value of @STATUS both as an output parameter and a result?
Anyway, the code that you showed earlier that created the parameter object should work just fine. After you have closed the reader, you can retrieve the value from the Value property of the parameter object. The value is returned boxed inside an object, so you have to unbox it by casting it to the type int.

ok problem has been solved using ExecuteReader.
I'm using below code to read next Resultset.
Reader = SqlHelper.ExecuteReader(pass parameters)
if !(Reader == null)
{
while(Reader.Read())
{
string str = Reader["param1"].ToString();
}
Reader.NextResult
While(Reader.read())
{
string str1 = Reader["Param2"].ToString();
}
}
Many many thanks for ur help too.
Thanks

Ok, but then you are not reading the value from the output parameter.

yes, no need to use output parameter.
if u know how to take value from output parameter then pls let me know.
that solution will also helpful to me

The property is named Value, not value. Other than that, the code is correct.

What exception does it fire? What is the error message?

There is no resultset returned, hence the name, ExecuteNonQuery.
You retrieve the output param value the same way from ExecuteQuery as you do with ExecuteNonQuery.
only two letters away from being an asset
