TITLE   :PRB: Wizstyle Add Button Does Not Add Child Record
PRODUCT :Microsoft FoxPro
PROD/VER:WINDOWS:5.0,5.0a
OPER/SYS:
KEYWORDS:kbvfp kbvfp500 kbvfp500a

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Add button, in all of the navigation classes in the WIZSTYLE class library
(Wizstyle.vcx), does not work correctly when adding a record to a child table.
This problem occurs when the field linking the Parent to the Child table is of
type Numeric.

RESOLUTION
==========

To workaround this issue, create a character version of the fields in each
table. The character fields can then be used to set the relation between the two
tables.

STATUS
======

Microsoft is researching this behavior and will post new information here in the
Microsoft Knowledge Base as it becomes available.

MORE INFORMATION
================

The WIZSTYLE class library (Wizstyle.vcx) contains many class definitions. There
are three class definitions that are used to navigate in tables: txtbtns,
picbtns, and verttxtbtns. Each of these classes have an Add button. In a
one-to-many table configuration if the field linking the Parent and Child tables
is of type numeric, then the Add button, for any of the navigation classes, does
not work correctly when adding a record to the child table.

The following steps illustrate the behavior of using the txtbtns navigation
buttons class on a One-to-Many form.

Steps to Reproduce Behavior
---------------------------

There are two parts in setting up this example: Part 1 is to create the two
tables used in the One-to-Many wizard. Part 2 is to create the One-to-Many form
using the wizard.

Part 1 - Create the two tables used in the One-to-Many wizard:

1. Save the following code to a file called Creatabs.prg:

         *** Begin code ***
         CREATE TABLE parent (Char1 C(2),  Id N(2))
         CREATE TABLE child (Id N(2), Value1 N(3), Value2 N(4))
         SELECT child
         INDEX ON Id TAG Id
         INSERT INTO parent (Char1,Id) VALUES ('11',11)
         INSERT INTO parent (Char1,Id) VALUES ('22',22)
         INSERT INTO parent (Char1,Id) VALUES ('33',33)
         INSERT INTO child  (Id,Value1,Value2) VALUES (11,111,1111)
         INSERT INTO child (Id,Value1,Value2) VALUES (11,123,1234)
         INSERT INTO child (Id,Value1,Value2) VALUES (11,134,1345)
         INSERT INTO child (Id,Value1,Value2) VALUES (22,222,2222)
         INSERT INTO child (Id,Value1,Value2) VALUES (22,234,2345)
         INSERT INTO child (Id,Value1,Value2) VALUES (33,333,3333)
         *** End code ***

2. Run Creatabs.prg that creates both tables and inserts values into each table:

Part 2 - Create the 'One-to-Many' Form:

1. From the Visual FoxPro File menu, select New, and then click Form. Click the
   Wizard button.

2. On the Wizard Selection dialog box, click the One-to-Many Wizard.

   a. In Step 1, move all the fields from the Parent table to the Selected
      fields pane.

   b. In Step 2, move all the fields from the child table to the Selected fields
      pane.

   c. In Step 3, click Next, as the parent.id = child.id is relation is
      correctly set.

   d. In Step 4, click Next after choosing a form style.

   e. In Step 5, move the Char1 field to the Selected fields pane.

   f. In Step 6, select the Save and Run button, and click Finish.

NOTE: At this point, the Save As dialog box appears. Once a name has been
entered, and the Save button is clicked, the form will run.

1. Click the Add button.

2. In the Add Record dialog box, click Add record to child (grid) only, and
   click the Add button.

NOTE: The wizard-generated code has not added a new record to the grid, nor it is
not possible to move the cursor into a blank row of the grid.
