The example code will be exactly as Pathan showed:
new FileStream(Server.MapPath(path), FileMode.Open, FileAccess.Read);
The path in the path variable should be a virtual path, like for example "/SomeFolder/SomeFile.txt".

I have a transaction that adds sql statements between postbacks that occur at specific button clicks. And the transaction is finally commited at another button click.
Each time the postback occurs the sql commands are added to the transaction without any problem but finally when i commit it, an exception occurs that says:
"This SqlTransaction is completed; it is no longer usable."
When I viewed the property of the transaction object while debugging I ve noticed a Timeout property that has the value 15. I dont know whether it is in seconds or minutes. I think it is due to the timeout the transaction is gettting completed.
I have declared the transaction globally in my page say "MemberLinking.aspx" as:
<br />
Private Shared myTrans As SqlTransaction<br />
I have then passed the transaction to a function defined in a class file like this:
<br />
Public Sub BeginTransaction(ByRef tsql As SqlTransaction)<br />
Try<br />
tsql = conn.BeginTransaction()<br />
Catch ex As Exception<br />
Finally<br />
End Try<br />
End Sub<br />
This function begins the transaction. The other functions that adds the commands to the transaction are also passed the transaction as parameter. Vut it is done by value.
I have added the sql statements to the transaction as:
<br />
sqlstatement = "UPDATE UserFamily SET UserID=" & LinkedUID & " WHERE UserID=" & UID & " AND FamilyID=" & FID<br />
cmd = ReturnSqlCommand(sqlstatement)<br />
cmd.Transaction = Mytrans<br />
cmd.ExecuteNonQuery()<br />
<br />
sqlstatement = "INSERT INTO UserFamily(UserID,FamilyID,Accepted,IsModerator) VALUES (" & ChildID & "," & FamilyID & _<br />
",1,0)"<br />
cmd = ReturnSqlCommand(sqlstatement)<br />
cmd.Transaction = Mytrans<br />
cmd.ExecuteNonQuery()<br />
where ReturnSqlCommand() is a function that takes as string a parameter and returns it as an SqlCommand object. The above two are not the only statements. The application adds a set of statements at each postbacks. Through out this process there is no error or exception utill i try to commit or rollback the transaction object.

AFAIK: Everytime you postback, your page and all it's code behind variables are recreated and reinitialized, but controls retain their values because of the magical viewstate.
SqlTransaction doesn't have any concept of viewstate, so it's a fresh new SqlTransaction each time.

Thank you Steve
Is it anyway possible to preserve the transaction b/w postbacks? Is there any chance of transaction getting timed out?

Hi all,
I'm trying to make an asp.net data entry table work like they do in access. what i want is a one line table with 3 columns (a time picker, a drop down, and a comments section). When the line is fully populated, I'd like a new empty line to appear below so the user can continue to add any number of lines.
I can't figure out any easy way to do this, and that usually means i'm missing something simple any help is greatly appreciated!
thanks in advance,
Craig

I have a gridview that, depending on the information being passed to it, needs to flag the Visible attribute of a textbox control in one of the template columns. so here is a quick snippet of the datarow as it is being built:
dr[4] = "";
dr[5] = s;
dr[6] = "false";
the datatable columns it references:
dt.Columns.Add("filler");
dt.Columns.Add("key");
dt.Columns.Add("Vis");
and the line in the gridview that is having issues:
<asp:TextBox ID="txtItmQty" runat="server" Text='<%# Bind("filler") %>' Width="42px" Visible='<%# Bind("Vis") %>'></asp:TextBox>
every time i run it, i get this:
<b>Specified cast is not valid.</b>
how or what do i have to pass to the Visible attribute to set this dynamically?

i m assuming that u store bool value in your "Vis" Field.According to that below solution is given...
public string GetValue(bool Vis)
{
if (Vis)
return "true";
else
return "false";
}
Visible='<%# GetValue(Convert.ToBoolean(DataBinder.Eval(Container.DataItem,"Vis"))) %>'
i thinks this will work

When i store a cookie, id doesn't remeber even if i use refresh
Using VS2005 SP1
Thank's in advance

How do you store the cookie, and how do you try to read it?

To Write
Response.Cookies["UserName"].Value = txtUserName.Text;
Response.Cookies["UserName"].Expires = core.cookieExpire();
Response.Cookies["Password"].Value = txtPassword.Text;
Response.Cookies["Password"].Expires = core.cookieExpire();
public DateTime cookieExpire()
{
DateTime dt = DateTime.Now;
dt.AddYears(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireYear"]));
dt.AddMonths(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireMonth"]));
dt.AddDays(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireDay"]));
dt.AddHours(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireHour"]));
dt.AddMinutes(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireMinutes"]));
return dt;
}
<configuration>
<appSettings>
<add key="CookieExpireYear" value="1"/>
<add key="CookieExpireMonth" value="0"/>
<add key="CookieExpireDay" value="0"/>
<add key="CookieExpireHour" value="0"/>
<add key="CookieExpireMinutes" value="0"/>
</appSettings>
<connectionStrings>
To Read
HttpCookie cookieUserName = Request.Cookies["UserName"];
HttpCookie cookiePassword = Request.Cookies["Password"];

The methods in the DateTime structure doesn't change the value, they return the new value. That means that the cookieExpire method returns DateTime.Now, which will make your cookies expire immediately.
This will give you a better result:
public DateTime cookieExpire() {
return DateTime.Now
.AddYears(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireYear"]))
.AddMonths(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireMonth"]))
.AddDays(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireDay"]))
.AddHours(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireHour"]))
.AddMinutes(Convert.ToInt32(ConfigurationManager.AppSettings["CookieExpireMinutes"]));
}
