DataLogger?

[charliehbeijer]

Can I do anything with a DataLogger besides show it in a TrendViewer? Can I accessthe records of a DataLogger in a script?

You can access the data via a report, export it using an action to a csv file, or directly query the database using SQL. I have attached a project that shows you how to query the databse via a script.

An example of how to create an Excel Report Template and generate a report that queries the database can be found in the samples section of the initial iX Developer startup screen. It is called "Sample_Report".

The action to export the datalogger data to a csv file is under the Database action listing.

Very nice.

Using the example file you posted, I have in my script:

using System.Data.SqlServerCe;

I'm getting an error message that SqlServerCe doesn't exist in System.Data.

I try using intellisense. I type "using System.Data.", and intellisense says I have Sql, SqlClient, and SqlTypes, but then if I say

using System.Data.Sql, it says Sql is not part of System.Data!

And no matter what I do, I can't resolve the type "SqlCeConnection" which appears in the example project you posted.

You need to add a Reference assembly to your project. If you open up the Script_Database_Export project and go to the Reference Assemblies, you will see that it has one.

Yes, I went there and clicked "Add", but System.Data.SqlServerCe.dll isn't in the list.

I found the dll under
C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\Devices

The database example works perfectly in simulate, and in the debugger, but crashes to the T7A screen on the flat panel.

In the main screen, if I just add
using System.Data;
using System.Data.SqlServerCe;
using System.IO;
using System.Reflection;

the program runs.

But if I then declare inside the partial class:

private SqlCeConnection m_SqlConnection;

the project won't start. It says: Missing Method Exception

Same thing if I say

private SqlCeConnection m_SqlConnection = null;

I'm picking up System.Data.SqlServerCe from
C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\Devices

Below is code that works on my Main screen. I think the issue is that you need to use the system.data.sqlserverce.dll contained in the attached zip file. I tried using the same one you are, and it is not working.

Code: Select all

namespace Neo.ApplicationFramework.Generated
{
    using System.Windows.Forms;
    using System;
    using System.Drawing;
    using Neo.ApplicationFramework.Tools;
    using Neo.ApplicationFramework.Common.Graphics.Logic;
    using Neo.ApplicationFramework.Controls;
    using Neo.ApplicationFramework.Interfaces;
    
	using System.Data;
	using System.Data.SqlServerCe;
	using System.IO;
	using System.Reflection;
    
    public partial class Screen1
    {
		private SqlCeConnection m_SqlConnection;
    }
}
