What is this built with? VC++? C#? VB? What is Main Report? A component you built? A third party control?

Well, what do the log files say?

This is because the fact that SQL doesnt has a datatype called time but DateTime.
What you can do is, in the design mode of your database table set the format as short time( or which ever suitable to you) Rose | [Rose]

The database isn't interested in the format of the DateTime. Setting some format only alters the way it is displayed. It will still store something for the date portion.

This means you still have to consider what date you are going to give it so that queries work as expected.

Assuming this is MS Sql Server, there is no Time datatype, only DateTime. You just need to ignore the Date portion of the DateTime field you're interested in.

Simply ignore the date part when you retrieve the value from the database.

Hi,

first of all, I hope you're validating the values of dtp_examdate, txt_time and txt_timeto before filtering your DataView.

There are few things you could try, and I'll be honest, I'm not sure if any of them is good.

1. You can place a hardcoded date value in the database, for example '2007-01-01' will always be the date part of your datetime field. Probably not a good idea, you'd still need to handle insert/update properly (by a trigger perhaps), and parse the time value when selected from the DB. I'd say too much overhead.

2. Perhaps better than 1: store the time value in separate tinyint fields, Hour, Minute, Second. I believe this way you can filter the data easily, you only need to combine the values to display the time properly.

Hope that helps D'Oh! | :doh:

Populate a *.sdf database from a dataset

Hi!

In my program i receive a data through TCP socket and i put them into a dataset. How can i insert these values into a .sdf (pocket pc/compact framework) database. Is there a method other than using an INSERT command for every dataset row? Because using INSERT is too slow. Sigh | :sigh:

Thank you!

I've found it usually isn't the INSERT that is slow it is the database roundtrips that are slow. If the framework supports it then you should batch a number of INSERTs into one Command and send them together.

SQL Server CE is in-process so the round-trip problem doesn't apply. The parser only accepts one statement per batch. The parser is appallingly slow and the query execution engine isn't much better. You actually get best performance by simply opening the tables directly (specify the table name for SqlCeCommand.CommandText and set SqlCeCommand.CommandType to CommandType.TableDirect) and not using SQL at all (ironically).

In CF 1.0 you could read tables directly but not update them - you had to use INSERT queries and Prepare the command object to avoid the query compiler overhead. CF 2.0 has a SqlCeResultSet class which is back to the ~~bad~~ good old days of ADO Recordset - you can scroll back and forth with a client-side cursor, seek to specific values, update or delete existing rows and insert new rows.

For SQL Server 2005 Mobile Edition/SQL Server CE 3.1, with .NET Compact Framework 2.0, you can manipulate the tables directly (as it's an in-process database engine).

Open a SqlCeResultSet directly on the table you want to insert into. Use the CreateRecord method to get a SqlCeUpdatableRecord, which you set the properties of. Then use the resultset's Insert method to update the table. Reportedly, this is much faster than using any SQL INSERT query, even if you Prepare the command object.

In fact SQL Server CE is reportedly much faster if you manipulate tables directly and use the navigation methods on SqlCeResultSet or SqlCeDataReader than using any form of SQL. Only use a SELECT query when you want to do a complicated join.

You can open an updatable resultset directly on a table by doing:

using( SqlCeCommand cmd = new SqlCeCommand( "MyTable", conn ) )
{
   cmd.CommandType = CommandType.TableDirect;
 
   using( SqlCeResultSet rs = 
      cmd.ExecuteResultSet( ResultSetOptions.Updatable ) )
   {
      // code to manipulate the resultset
   }
}

Note that this is unique to SQL Server CE - you cannot open tables directly with the full SQL Server 2000 or 2005.

Suppose the next code:

<StackPanel Orientation="Horizontal" Width="120" Height="30">
<Ellipse Fill="#FFBF5757" Stroke="#FF000000" />
</StackPanel>

How do I to make the ellipse the same width of the stackpanel?

<StackPanel Orientation="Horizontal" Width="120" Height="30" <b>x:Name="panel"></b>
<Ellipse Fill="#FFBF5757" Stroke="#FF000000" <b>Width={panel.Width}</b> />
</StackPanel>

I don't know how. Thanks for any help

If Ellipse is always supposed to be the same width as the StackPanel, get a handle on the Elipse node and use node.Parent to get at StackPanel.
