Hi,
.net 2 vs2005
I have a winform app with a close button. The code behind the close is this.Close(); this.Dispose();
The problem is that after deploying my app, in the task manager I can still see my exe under processes after pressing the close button. Do I need to shut down differently?
Thanks,
Chas

You don't need to call this.dispose on the apps main form. If you started it up correctly (by using Application.Run(new Form1());) then the calling code will do the dispose for you. Do this first, and check that it's not causing your problem.
Apps remaining running is usually because you haven't stopped a background thread somewhere. Are you using any background workers, or threads, or anything like that? Check they are all stopped and disposed of before the form is closed.

ServerManager mgr = new ServerManager();
mgr.ApplicationPools["test"].Enable32BitAppOnWin64 = true;
mgr.CommitChanges();
Above code should set property Enable32BitAppOnWin64 to true for application pool having name test, but it doesn't do that, can anyone please tell what am I doing wrong.
Please note that ServerManager class is present in Microsoft.Web.Administration namespace.
Thanks,

Do you get any exceptions? I use the following code and it works fine for me (cutdown a bit):
using (ServerManager mgr = new ServerManager())
{
ApplicationPool appPool = mgr.ApplicationPools[appPoolName];
if (appPool == null)
throw new ApplicationException(string.Format("The pool {0} does not exist", appPoolName));
appPool.Enable32BitAppOnWin64 = true;
mgr.CommitChanges();
}

Hi Pete,
Thanks for the response and sorry for the late reply.

No, I don't get any exception.
I have observed when i try to set property through code it shows me that the property has been successfully changed to true even next time I try to get that property programmatically it shows me that property is true, but when I open that in IIS it shows me that property to be false.
Please check the screen shot for that.

Hi Pete O'Hanlon,
I was checking that property incorrectly, you are right that your mentioned code is working fine.
Thanks a lot.

hello
I am trying to get the return parameter from database stored procedure (very simple basic test):
create procedure TQMSpGetConcattenatedString @string1 varchar(50),@string2 varchar(50),@string3 varchar(50) output
as
set nocount on
select @string3 = @string1 + @string2
works fine when execute in query analyser. Then try to execute from C# code as follows:
private static string test2()
{
IDbCommand cmd = Program.db.GetCommand ();
cmd.Connection = Program.db.Connection;
cmd.CommandText = "TQMSpGetConcattenatedString";
cmd.CommandType = CommandType.StoredProcedure ;
IDataParameter p1 = Program.db.getDataParameter ();
p1.ParameterName = "@string1";
p1.Direction = ParameterDirection.Input ;
p1.DbType = DbType.String ;
p1.Value = "Monkey";
cmd.Parameters.Add (p1);
IDataParameter p2 = Program.db.getDataParameter ();
p2.ParameterName = "@string2";
p2.Direction = ParameterDirection.Input ;
p2.DbType = DbType.String ;
p2.Value = "Tail";
cmd.Parameters.Add (p2);
IDataParameter p3 = Program.db.getDataParameter ();
p3.ParameterName = "@string3";
p3.Direction = ParameterDirection.Output;
p3.DbType = DbType.String ;
p3.Value = "-";
cmd.Parameters.Add (p3);
cmd.ExecuteNonQuery ();
return p3.Value.ToString();
}
the return string only has 1 character in it. When i use SqlParameter it works good.
Does anybody have a suggestion for me?

Don't use this. You're executing a query, so use something like ExecuteDataReader() instead. Also, you need to close your connection and command. I suggest that you wrap them up in using blocks.

Thanks for the suggestion!
I'm not executing a query but a stored procedure.
your suggestion does not change the result.
by the way: what 's the advantage of a using block?
|
|
|
|
|
ExecuteNonQuery is used for update/insert type queries (or stored procs) which do not return data.
The advantage of a using block is that it automatically closes/disposes for you.
you do not get the value of the output parameters until your connection is closed. A starnge thing, but there you are, thats how it works.

Like i say before: when i use SqlDataParameter and not IDataParameter it works fine.
But i want to be able to connect to SqlServer OR Oracle database, so i try IDataParameter.
So it has to with the parameter, not the connection. When i do not set the size for a SqlParameter, the result is also the first character only. However i cannot set the size for IDataParameter.
|
|
|
|
|
You don't need to assign a value to your output parameter. I suspect that it may be setting the size of the parameter because you only assign a single character to the input here.
|
|
|
|
|
tried that: an null value resluts in an error (invalid size property),
a very long string or empty string or gives the same result (only one char).
|
|
|
|
|
What character do you get back? Is it the one you'd expect?
|
|
|
|
|
It is the "M" from "Monkey", but i want "MonketTail".
|
|
|
|
|
found it!
I incidently selected IDataParameter interface, which should have been IDbDataParameter.
IDbDataParameter parameters have a size property.
Thanks for the trouble taken to try to help!
bye.

Hi all,
I have a problem with DateTimePicker and BindingSource.
The BindingSource DataSource is a DataTable of 3 Columns (ID, Name, and Date).
The "ID" Field is Primary key that of cource doesn't allow nulls.
Both "ID" and "Name" fields are bound to TextBoxes, and "Date" Field is bound to a DateTimePicker control.
Now when I'm trying to add a new record, I got an exception of:
"Column 'ID' does not allow nulls."
although it has a value.
when I don't bind "Date" field, problem doesn't occur
Can you help meeee?? 
|

Before actually adding a the new record, you should clear the datetimepicker's databinding, using the method datetimepicker1.DataBindings.Clear() in C#. After that binding the datetimepicker1 to the same data source it's bound before.

Control.Invoke((MethodInvoker)delegate()
{
});
This is a syntax of a code which i have copied but i didn't understand use of "MethodInvoker" here.
can any body explain me.

You cant pass an anonymous delegate into a method expecting a Delegate type. You need to cast it to a compatible delegate type.
