This sample illustrates the simplest scenario for a single-user, single-table data entry form.

The ControlSource property of each of the text boxes and combo boxes on the form is set to a field in the Customer table.

An APPEND BLANK command is issued in the Click event of cmdNew.

В Copy Code
APPEND BLANK
THISFORM.Refresh

The DELETE command is issued in the Click event of cmdDelete.

В Copy Code
* cmdDelete.Click
#DEFINE MSGBOX_YES      6
#DEFINE C_MSGBOX1      36
#DEFINE C_DELETE_LOC   "Are you sure you want to delete this record?"

IF MESSAGEBOX(C_DELETE_LOC,C_MSGBOX1) = MSGBOX_YES
   DELETE
   IF !EOF()
      SKIP 1
   ENDIF
   IF EOF() AND !BOF()
      SKIP -1
   ENDIF
   THISFORM.Refresh
ENDIF

Extending the Data Entry Form

To create a more robust data entry form, one that makes it possible for a user to cancel changes or makes it possible for multiple users to access the same data, you need to use transactions and table or row buffering.
