use it before pass to DB
if (CompletionDate == null)
{ cmd.Parameters.AddWithValue("@CompletionDate",System.Data.SqlTypes.SqlDateTime.Null);
}
else
{
cmd.Parameters.AddWithValue("@CompletionDate", CompletionDate);
}
and also in DB "CompletionDate" field shulid allow null

Oh, you were answering, not asking. The code you posted is still messy, even if SqlDateTime.Null works.

How do you know it allows null ? In any case, your error is not that null is not allowed, but that the date object is broken. I think you need to make your code typesafe, walk through with the debugger and see what date is passed in. You also need to fix your code where it is prone to breaking.

This is messy. What if the text entered cannot be converted ? This code is fragile and not production quality, on many levels.
I need to see the code that throws that error, in order to comment on it.

DateTime? StatusDate,CompletionDate;
if (txtStatusDate.Text != "")
{
StatusDate = obj.ConvertStringToDate(txtStatusDate.Text);
}
else
{
StatusDate = null;
}
i am get error in below code
public Boolean InsertTask(string oprtype, object StatusDate)
{
Database db = DatabaseFactory.CreateDatabase();
string sqlcommand = "DailyReport";
DbCommand dbcommand = db.GetStoredProcCommand(sqlcommand);
db.AddInParameter(dbcommand, "@oprtype", System.Data.DbType.String, oprtype);
if (StatusDate != null)
{
db.AddInParameter(dbcommand, "@StatusDate", System.Data.DbType.DateTime, StatusDate);
}
else
{
db.AddInParameter(dbcommand, "@StatusDate", System.Data.DbType.DateTime, DBNull.Value);
}
db.ExecuteNonQuery(dbcommand);
return true;
}

Why are you still passing this as an object ? In any case, if this is passing DBNull.Value, and the procedure fails, then your database doesn't support null. That's really about it. Have you tried running the proc directly against the database ? What does the proc look like ?
I can't help but feel that if you made this code typesafe, it might well work. You're not passing a datetime, you're passing an INullable<DateTime> and I can't help but wonder if that makes a difference, when all you tell the compiler is that it's an object.

Copy the files onto the server. Make sure the server has ASP.NET installed. Point IIS to your site.

Step1:Make sure that the IIS is Installed,

Step 3: Create an Virtual Directory

Hi, How can I create a move next command in web development???
Dim DS As New DataSet
TextBox1.Text = DS.Tables(0).Rows(DS.Tables(0).Rows.Count() + 1).Item("ITEM_NAME")
This code that I've used just give a move last command and i can't figure out how to the move next so that I can look for the items in my data base one-by-one.
can you give me some solution?
Thanks a lot in advance.
|
|
|
|
|
do you want to show the ITEM_NAME one by one in textbox?
Cheers!!
Brij
|
|
|
|
|
yes, that's what I'm trying to do. But the code that I've used only showed me the last item in my query.
|
|
|
|
|
You can do onething
Start from 0,increment it and save it in viewstate then next commond take the value from viewstate and show it again same way increment and save it viewstate .Do the same till last element.And show the value like below
TextBox1.Text = DS.Tables(0).Rows(int.Parse(viewstate["counter"])).Item("ITEM_NAME")
Cheers!!

I've tried your code but there are some errors. The "int" can't be loaded and there's a identifier need in the ["counter"] part.

Keep a Global Variable
and increment it's value when u click on MoveNext
Global Variable intGlobalCount
TextBox1.Text = DS.Tables(0).Rows(intGlobalCount ).Item("ITEM_NAME")
|
|
|
|
|
how can i declare this Global Variable?
|
|
|
|

Global variables are ALWAYS a sign of bad design and bad programming. In any case, where would he keep it so that it maintains it's state between postbacks ?

yes your right. I've tried to make a variable to act like a counter but ever time the page will postback, the value of the counter will return to its original value.

Well, the basic issues you have are:
1 - you are requesting the last row ( actually one past ), so that's what you see
2 - as it's a website, if you want the user to click next, and then see a new record, what you're doing is very wasteful. Why not just request the row you want to see ?
3 - the best place for you to store an index of the current record, is the URL. The second best, is viewstate. A static variable is an idiotic idea, it will break your site as soon as you have two users.
