SUMMARY

You can use a Private Data Session in Visual FoxPro as one of the properties of the form. This will allow two sessions of the same form to run with a separate record pointer in each instance.

1. Type the following command in the Command window, and press the ENTER

   key:

   Create Form test

   Environment.

3. Using the right mouse button, click the Data Environment, and select

   Add.

4. Select the Other option in the Add Table or View dialog box.

5. Select the Customer table from the \VFP\SAMPLES\DATA directory.

6. Drag the Company field from the Data Environment to the form. Note that

   the control source property should be Customer.company.

   command Skip, and press the ENTER key. Then type the command
   Thisform.Refresh, and press the ENTER key. Close this window.
