i have not read you last post. from this one if I understood you correct,

DateTime current = DateTime.Now;
//inputDate is the date specified by customer

Timespan t = current.Subtract(inputDate );

The timespan object will have the difference. i.e. re.TotalHours will have the hour difference.

your code does make sense.

Could you please tell me a bit detail

1. You are right, input is coming from customer
2. If I substract the input then do I need to specifie any format ex. 10/02/09 5:47

Convert.ToDateTime uses the current culture. If you want to do culture specific stuff then u wud have to use DateTime.Parse passing it the culture.

Timespan's TotalHours property does give you the total difference of hours ?

There is no other possibilities. ASP.NET can't read the folder and put files to DB.

well I used this and it works.

string sFilePath = @"C:\FF73JJ0000.tif";

byte[] bFile = new byte[fs.Length];
fs.Read(bFile, 0, bFile.Length);

SqlConnection connection = new SqlConnection(connectionString);

connection.Open ();
SqlCommand cmd = new SqlCommand ("insert into tblViewContracts "
+ "(ViewImage) values (@pic)", connection);
cmd.Parameters.Add ("@pic", bFile);

this kinds of works.

Usually ASP.NET user account will have read/write access in the website area. If not, it can be granted from the Properties window of that directory. Code accessing C:\SomeFolder may fail as ASP.NET will not have access to directories outside website area.

If string to DateTime conversion is yur problem then u can use, Convert.ToDateTime("10/02/2009 03:37:25") to make a DateTime object of your string. Alternately, DateTime.Parse.

DateTime Dt= DateTime.Parse("10/02/2009 03:37:25");
DateTime Dt2 = DateTime.Parse("10/02/2009 14:30:00");
TimeSpan t = Dt.Subtract(Dt2);
MessageBox.Show(t.TotalHours.ToString());

Now From Time Span you can get the time Difference Wink | ;)

It looks like the date OP is talking about is in dd/mm/yyyy format. If yes, your code will fail. It will take 02 as date and 10 as month. You need to use DateTime.ParseExact with an invariant culture and required format.

Session array

Sandraa9-Feb-09 9:59

9-Feb-09 9:59

Hi all, somebody knows how create a array multi-dimensional with session variables.
I have it:

Session("Preguntas") = LPH.ObtenerTest(Session("Articulo"), Session("Nivel"))

where it session is a table and I want to add the result of client into other session array but with 2 columns, something similar to

Session("ArrayRespuestas")(Session("i"), 1) = "1"

.

I use session variable because when the user make click into button I receive a postback and lost my original select (LPH.ObtenerTest(Session("Articulo"), Session("Nivel"))) that is a procedure that return a select random with 2 parameters.
If I use

If Not Me.Page.IsPostBack Then

and put my select into later (the second page_load) doesn't load my select and when I call to

Preguntas.Rows(i)("Respuesta1")

I received a error where told me that I must first create a object.

Thanks for all.

The below code allows a multi-dimensional array to be stored in the session state. See if you can adapt this to fit your use. Good luck.

private void StoreToSession()
{
     string[,]initialArray={"A","B"};
     Session["sessionvalue"]=initialArray;
}

private void ReteriveFromSession()
{
     string[,]resultantArray=(string[,])Session["sessionvalue"];
     TextBox1.Text=resultantArray[0,0].ToString();
     TextBox2.Text=resultantArray[0,1].ToString();
}

Doesn't work because the postback empty my array when I push btton.
I have when load the first ask (is a test of 25 ask):

Public Ar1(25, 1) As Integer

Procedure of load ask

Ar1(Session("i"), 0) = Session("Preguntas").Rows(Session("i"))("Id_Pregunta")
Session("ArrayRespuestas") = Ar1

later when button_onclick:

Dim respuesta As Integer
        If RadioButton1.Checked = True Then respuesta = 1
        If RadioButton2.Checked = True Then respuesta = 2
        If RadioButton3.Checked = True Then respuesta = 3
        If RadioButton4.Checked = True Then respuesta = 4
        If RadioButton5.Checked = True Then respuesta = 5
        Ar1(Session("i"), 1) = respuesta
        Session("ArrayRespuestas") = Ar1
        Session("i") = Session("i") + 1

This work without errors, but when I try to recovery the datas of array I only get the value present Ar1(Session("i"), 1) but I lost the value Ar1(Session("i"), 0) because was added before of push button and later the postback empty my array.
Good, realty is when I put Session("ArrayRespuestas") = Ar1 is when I clear my session array.

I believe that the solve is to search like get not postback when click button.

I accept advisers boys Smile | :)

Re: Session array

Sandraa11-Feb-09 8:49

Solved
I put into page_load

If Not Me.Page.IsPostBack Then
    Session("i") = 0
    Dim Ar1(25, 1) As Integer
    Session("ArrayRespuestas") = Ar1
End If

Then only I define the array a time Smile | :)

Thanks for your help Wink | ;-)

Hi,
my page postbacks many times and this button click occurs in between postbacks(one postback occurs due to button click).
when a particular button is clicked for the first time, a snippet will be executed and for other clicks of same button 'this' snippet should not be executed but some other code should be executed and for all clicks(including first click) it should remember(append the values to gridview) the previous values selected.
how can i achieve this senerio. IsPostBack is not applicable. Is there anyway to check clicks and save values in gridview (gridview is not in stored in DB)..
hope i am clear.. any doubts on my question are welcome....
Thanks in advance
