PRB: AutoOpenTables/AutoCloseTables Ignored in Program

• Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

SYMPTOMS

When creating a form visually, you discover that the data environment's AutoOpenTables property is set to True (.T.) by default and the tables and views will automatically be opened when the form is run. If the data environment is instantiated from within a program, the value of AutoOpenTables and AutoCloseTables is ignored.

WORKAROUND

Call the OPENTABLES or CLOSETABLES methods directly.

STATUS

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

Steps to Reproduce Behavior

1. Create a new program file, and type the following code:

   ******* Begin Program **********

   public oData1 oData1=CREATEOBJECT("MyData") && Instaniate the Data Environment

      DEFINE CLASS MyData AS dataenvironment   && DataEnvironment Class
      Name = "Dataenvironment"
      AutoOpenTables=.T.
      AutoCloseTables=.T.
      ADD OBJECT "Cursor1" AS MyCursor     && ADD OBJECT for each
      ENDDEFINE                            && cursor in Dataenvironment
   
      DEFINE CLASS MyCursor AS cursor      && Cursor Class
      Alias = "author"
      Database = "C:\vfp\samples\data\testdata.dbc"
      CursorSource = "customer"
      Name = "Cursor1"
      ENDDEFINE
   
      ******* End Program *******
   
   

2. Run the program.

3. Check the View window. You will see that no tables are opened. The Data Environment's AutoOpenTables is ignored.

4. In the Command window type:

   oData1.OpenTables

   NOTE: If the Testdata.dbc is not in your Path, you need to locate it.

5. Note that the table is opened.

6. Inside the Command window, type:

   oData1.CloseTables

7. The OpenTables/CloseTables must be called directly because AutoOpenTables and AutoCloseTables are ignored.
