Thanks you! I try it but not OK. My problem is "DayTo", I run in application is OK all, no problem. But when I publish it and run in my localhost ( IIS) at the same machine, it can't insert or update day >12. I think have wrong format, but I change day in my localhost by 31/05/2013, and test TimeNow still insert in my database is 31/05/2013 12:00:00 AM ok.

Solution 2

Check this line

object[] pa1 = {"day1",DateTime.Parse(txtTimeTO.Text),"@timenow",DateTime.Now,"@user",txtuser.tex};

-> you have provided parameter "day1" instead of "@day1";

-> You converting txtTimeTO.Text to DateTime , try DateTime.Parse(txtTimeTO.Text+" 12:00:00 AM")

DateTime should be in format 31/05/2013 12:00:00 AM.
As you are providing only date it is throwing error.

Thanks you,
-> you have provided parameter "day1" instead of "@day1"; -> yes, OK
I fix it. But my application run is OK in all case, but when I publish it and run in my IIS at the same machine, case "13/05/2013" not OK. I all format in my code and machine is "dd/MM/yyyy".
Thanks you!

C#

string replace_day1= your desired date.ToString("dd/MM/yyyy");
string replace_timenow=your desired date.ToString("dd/MM/yyyy");

C#

string insert1 = "insert into tbHangNhap(DayTo,TimeNow,TenDangNhap)values(@day1,@timenow,@user)";
Sqlcommand cmd=new Sqlcommand(insert1,your connection);
cmd.Parameters.Add(new SqlParameter("@day1", replace_day1));
cmd.Parameters.Add(new SqlParameter("@timenow",replace_timenow));
cmd.executenonquery();

Another Alternative:

C#

string replace_day1= your desired date.ToString("dd/MM/yyyy");
string replace_timenow=your desired date.ToString("dd/MM/yyyy");

C#

string insert1 = "insert into tbHangNhap(DayTo,TimeNow,TenDangNhap)values(@day1,@timenow,@user)";
object[] pa1 = {"@day1",replace_day1,"@timenow",replace_timenow,"@user",txtuser.tex};
