The VAOperation property determines what operation will be performed when the button is clicked at run time.
If the VAOperation property specifies a record retrieval operation, you can use the
VALockBias property to lock the record when it is retrieved. The
VALockBias property has no effect on Open, Close, Insert, and Update operations.
The VAErrorDialog property enables or disables the display of a text message to the user if the operation performed by the control returns an error.
Note: The Click event executes the code in the VACommand_Click subroutine before the PSQL operation specified in the VAOperation property is executed.
