Hi programmers,

Please make sure that:
1) your Win-CE Project has a reverence to System.Data.dll v 2.0;
2) .NET Compact Framework v 2.0 is installed on your development workstation (by default, \Program Files\Microsoft.NET\SDK\CompactFramework\v2.0\);
3) .NET Compact Framework v 2.0 is installed on the mobile device (or emulator) where you are deploying your application (launch the \Windows\cgacutil.exe utility on your device).

For more information, refer to http://en.wikipedia.org/wiki/.NET_Compact_Framework.

i have a reference to System.Data which refer to C:\Programme\Microsoft.NET\SDK\CompactFramework\v2.0\WindowsCE\System.Data.dll

Code: Select all

using System.Windows.Forms;
using System.Data;
using Devart.Common;
using Devart.Data;
using Devart.Data.Oracle;

namespace PalettenKontrolle
{
    public partial class frmPalCheck : Form
    {
        private Devart.Data.Oracle.OracleConnection oraCon;
        public frmPalCheck()
        {
            InitializeComponent();
            oraCon = new OracleConnection();
            oraCon.Sid = "db_sid";
            oraCon.Port = 1521;
            oraCon.Server = "server";
            oraCon.UserId = "user_id";
            oraCon.UserId = "user_pw";
        }

        

        private void frmPalCheck_KeyDown(object sender, KeyEventArgs e)
        {
            switch (e.KeyValue)
            {
                case 112:
                    this.Close();
                    break;
                case 113:
                    this.Close();
                    break;
            }
        }

       
    }
}

All references are set correctly...

It's not my first project for WinCE, but the first using devart components...

btw: System.Data.DataSet dsTest = new DataSet(); works while commenting all devArt references !!! ???

Which edition of dotConnect for Oracle are you using?

The .NET Compact Framework support is available only in the Mobile edition of dotConnect for Oracle: http://www.devart.com/dotconnect/oracle/editions.html. You should add the referece to Devart.Data.Oracle.dll from the Mobile edition (the Devart.Data.Oracle namespace) into your project. You can check your current edition via the Tools > Oracle > About menu of Visual Studio.
