FIX: Errors When Accessing rdoPreparedStatements Not Consistent

MORE INFORMATION

Steps To Reproduce Problem

1. Create a DSN in the 32-Bit ODBC section of the Control Panel. Name it "pubs" and configure it to point to the pubs database on a Microsoft SQL server.
2. Start the 32-bit edition of Visual Basic version 4.0 for Windows. Form1 is created by default.
3. Add two Command buttons to the form.
4. Add the following code to the General Declarations section of Form1:
   
   

         Option Explicit
   
         Private Sub Command1_Click()
           Dim rdocon As rdoConnection
           Dim rdoprep As rdoPreparedStatement
           Set rdocon = rdoEngine(0).OpenConnection("pubs", False, _
                                                    False, "uid=;pwd=;")
           Set rdoprep = rdocon.rdoPreparedStatements("Test1")
         End Sub
   
         Private Sub Command2_Click()
           Dim rdocon As rdoConnection
           Dim rdoprep As rdoPreparedStatement
           Set rdocon = rdoEngine(0).OpenConnection("pubs", False, _
                                                    False, "uid=;pwd=;")
           Set rdoprep = rdocon.CreatePreparedStatement("Test", _
                                                  "Select * from Authors")
           Set rdoprep = rdocon.rdoPreparedStatements("Test1")
         End Sub
   						

5. Press the F5 key or click Start on the Run menu to run the application. Click Command1, and you should see that Visual Basic gives the following error: (At this point the prepared statement has not been created.)
   40054 - invalid parameter.
6. Stop Visual Basic by using Stop on the Run Menu. Press the F5 key or click the Run menu again. Click the second button. This time the error will be different as the code has created a prepared statement:
   
   
   40041: Couldn't find object indicated by text.
