Steps to Reproduce Problem
--------------------------

1. In Visual FoxPro (VFP), save the following code as a program:

  *!*
  SET STRICTDATE TO 1
  #DEFINE DBCNAME 'testdb'
  #DEFINE TABNAME 'testtab'
  #DEFINE TABCOUNT 1

  CLEAR
  CLOSE DATABASES ALL
  DELETE FILE testdb.DBC
  DELETE FILE testdb.dc?

  CREATE DATABASE DBCNAME

  FOR lni = 1 TO TABCOUNT
  	DELETE FILE (TABNAME+ALLTR(STR(lni)))+'.dbf'
  	DELETE FILE (TABNAME+ALLTR(STR(lni)))+'.cdx'
  	CREATE TABLE (TABNAME+ALLTR(STR(lni))) (F1 C(10) NOT NULL ;
  		PRIMARY KEY, F2 d NOT NULL)
  ENDFOR

  USE testtab1
  FOR lni = 1 TO 3
  	INSERT INTO testtab1 (F1, F2) VALUES ('Number '+ALLTR(STR(lni)), DATE()+lni-1)
  ENDFOR

  CREATE SQL VIEW vtesttab1 AS SELECT * FROM testtab1 WHERE F2 = ?dDate
  DBSETPROP('VTESTTAB1', 'View', 'UpdateType', 1)
  DBSETPROP('VTESTTAB1', 'View', 'WhereType', 1)
  DBSETPROP('VTESTTAB1', 'View', 'SendUpdates', .T.)
  DBSETPROP('VTESTTAB1', 'View', 'Tables', 'testdb!testtab1')
  DBSETPROP('VTESTTAB1.f1', 'Field', 'KeyField', .T.)
  DBSETPROP('VTESTTAB1.f1', 'Field', 'Updatable', .T.)
  DBSETPROP('VTESTTAB1.f1', 'Field', 'UpdateName', 'testdb!testtab1.f1')
  DBSETPROP('VTESTTAB1.f1', 'Field', 'DataType', "C(10)")

  DBSETPROP('VTESTTAB1.f2', 'Field', 'KeyField', .F.)
  DBSETPROP('VTESTTAB1.f2', 'Field', 'Updatable', .T.)
  DBSETPROP('VTESTTAB1.f2', 'Field', 'UpdateName', 'testdb!testtab1.f2')
  DBSETPROP('VTESTTAB1.f2', 'Field', 'DataType', "d")
  DBSETPROP('VTESTTAB1', 'View', 'ParameterList', "dDate,'D'")

  cDate = "{^"+TRANS(YEAR(DATE()))+"-"+TRANS(MONTH(DATE()))+"-"+TRANS(DAY(DATE()))+"}"
  ?cDate

  lcFails = .T.  && Change this to .F. for it to work correctly.
  IF lcFails
     _CLIPTEXT = cDate  && This fails
  ELSE
     dDate = &cDate  && This works
  ENDIF

  USE vtesttab1
  BROWSE NOWAIT

2. Run the program that you just created. When the View Parameter dialog box
  appears, press CTRL+V to paste in the date that is contained in the
  clipboard.
