SUMMARY

With Microsoft(r) ActiveSync(r) 3.1 and ActiveX(r) Data Objects (ADO) for the Microsoft Windows(r) CE operating system (ADOCE) 3.1 installed, you can manually export tables from a Windows CE-based device to a desktop computer. This is convenient if you update data in a single table in a database. This article describes the steps to export tables from a Windows CE device to a Microsoft Access database.

How to Export a Table from ADOCE to Microsoft Access

With Microsoft ActiveSync 3.1 and the ADOCE control installed, you can manually export tables from a Windows CE-based device to a desktop computer. This is convenient if you update data in a single table in a database, or if you want to save time. It is faster to transfer selected tables in a database than to transfer the contents of an entire database. In the Export from Mobile Device to Database dialog box, you can choose which tables on the device to convert to a Microsoft Access database.

To export an ADOCE database, follow these steps:
  1. Connect the device to the desktop computer, and open the ActiveSync 3.1 window.
  2. On the Tools menu, click Export Database Tables. The Export from Mobile Device to Database dialog box appears, which displays the ADOCE tables on the connected device.
  3. To select a Microsoft Access .mdb file, click Browse. You can also type the path and file name in the Location text box. ADOCE creates the file if it does not exist.
  4. Select the check boxes for the tables that you want to export, and clear the check boxes for the tables that you do not want to export. ADOCE places the selected tables in the same .mdb file.
  5. Select the Overwrite existing tables and/or data check box to replace tables in the .mdb that have the same names as the selected ADOCE tables.
  6. Click OK to begin the conversion.
For each .mdb file that is exported, the converter generates a log file named Ce2db.txt in the partner directory for the device, which is usually in the C:\Program Files\Windows CE Services\Profiles\Devicename folder.

To export data from a device into an Open Database Connectivity (ODBC) data source, follow these steps:
  1. Connect the device to the desktop computer, and open the ActiveSync 3.1 window.
  2. On the Tools menu, click Export Database Tables.
  3. In the Export from Mobile Device to Database dialog box, click Browse.
  4. In the Choose Your New Database's Filename dialog box, in the Save as Type combo box, click ODBC Database.
  5. Select an ODBC data source.
  6. Select the check boxes for the tables that you want to export, and clear the check boxes for the tables that you do not want to export.
  7. In the Choose Your New Database's Filename dialog box, select the Overwrite existing tables and/or data check box to replace tables in the existing database that have the same names as the selected ADOCE tables.
  8. Click OK to begin the conversion.
For each .mdb file that is exported, the converter generates a log file named Ce2db.txt in the partner directory for the device, which is usually in the C:\Program Files\Windows CE Services\Profiles\Devicename folder.

Additional Information

The following options are available in the Export from Mobile Device to Database dialog box:
  • Location text box:

    This text box specifies the Microsoft Access .mdb file in which to store the selected tables. Type a path and file name, or use the Browse button to select an existing file or change directories. The default database location and name is <Device Partner Folder>\Dbxx.mdb, where the number xx represents the next available number. If the file that is specified in the Location text box does not exist, ADOCE creates one.
  • Select the tables to copy list box:

    This list box displays every table that ADOCE can read, except the ADOCE system tables. To select the table for conversion, select the check box by the table name. ADOCE places the selected tables in the same .mdb file.
  • Overwrite existing tables and/or data check box:

    When you select this check box, if you have tables in the selected database with the same name as tables that appear in the window, the existing tables are replaced with the converted ones. If you clear this check box, the converter generates an error if it finds a table with the same name. You cannot merge the data in an ADOCE table with existing data in a Microsoft Access table.
  • Default button:

    Click this button to select the default tables for conversion. ADOCE automatically selects all tables.
  • OK and Cancel command buttons:

    Click OK to start to convert the selected tables. Click Cancel to quit the conversion.
