More information

Microsoft Visual FoxPro

Overview

This service pack contains enhanced language features and bug fixes. For details on language and feature changes included in this update, see VFPSP3.CHM located in the Visual FoxPro 6.0 root directory. VFPSP3.CHM provides the details on the following Visual FoxPro 6 features:
  • Servers - The primary emphasis of Service Pack 3 is multithreaded server work. Three-tier applications use Visual FoxPro MTDLL servers in the middle tier. Ideally, you use these servers with IIS, ASPs, FoxISAPI, MTS, and MSMQ. You can also use the MTDLL server with dual and multi-processor machines if you have them available. You should review the "Language not Supported in MTDLL" section in the server additions file, VFPSP3.chm, to ensure your MTDLL servers do not include any of the affected language.
  • Session class - Creates a custom, user-defined object that manages its own data session.
  • Run-time compiler support - Ensures your existing applications work and function correctly as they did in Visual FoxPro 6.0. Rerun and recompile all your applications to make sure they behave properly.
  • ActiveX Controls - Several improvements were made to ActiveX control support to make it possible for the OleControl control to work with more types of ActiveX controls, such as the Microsoft Hierarchical Flexgrid.

Enhanced and New Language Elements

This update to Visual FoxPro includes the following new and enhanced commands and features:
  • AddLineFeeds property - Formats edit box contents with carriage return-line feed characters.
  • BUILD MTDLL - Creates a multithreaded DLL.
  • COMPILE command - Adds run-time support.
  • Session Class - A custom, user-defined class that manages its own data session.
  • StartMode property of _VFP - Indicates how an instance of Visual FoxPro was started.
  • ThreadID property _VFP - Returns the Win32 ID of the thread on which the object was called.
  • ProcessID property _VFP - Returns the unique identifier of the current process.

Coverage Profiler
  • 221623 Coverage Profiler Marks Unexecuted Lines in "IF...ENDIF"
  • 221672 Coverage Profiler Does Not Accept Long Coverage File Names

Known Issues

  • FGETS function update

    A minor behavior change was necessary for the FGETS() function related to Knowledge Base article 221747 (C0000005 Fatal Error Passing FGETS() a String >256 chars). The optional nBytes parameter now has a maximum value of 8192. By definition, FGETS() will only return bytes up to a carriage return if one is encountered before the parameter value is reached.
  • Gridbtns class

    A problem exists in the GridBtns class of Wizards\Wizbtns.vcx which prevents data from being saved on certain data input forms. If you drop this class (also referenced in the Component Gallery as Simple Edit Buttons) onto a data input form, edits to records will not be saved. This class is also used by the Form Wizard with the Scrolling Grid style, however, the problem does not exist with these generated forms.

    To work around this problem: Replace contents of CheckError method with the following:
    #DEFINE ERR_UNIQUEKEY3_LOC "A unique key error violation has occurred. That record will be reverted."
    #DEFINE ERR_RVIEWUPDATE_LOC "A problem occurred updating the remote data. That record will be reverted."
    
    AERROR(aGetErrors)
    
    IF aGetErrors[1] = 1884
       * Uniqueness ID error
       MESSAGEBOX(ERR_UNIQUEKEY3_LOC)
       TABLEREVERT(.T.)
       RETURN
    ENDIF
    
    IF CursorGetProp("sourcetype",.ALIAS)=2
       * If failed to update, check for remote view and revert
       MESSAGEBOX(ERR_RVIEWUPDATE_LOC)
       TABLEREVERT(.T.,.ALIAS)
       RETURN
    ENDIF
    Replace the following section of code in the Destroy method:
    IF USED(.ALIAS) AND ATC("CURSOR",.BaseClass)#0 AND ;
       CursorGetProp("sourcetype",.ALIAS)=3 AND ;
       CursorGetProp("buffering",.ALIAS)>1
          TableRevert(.T.,.ALIAS)
          * If your form has General fields, there is a possibility
    With the following:
    IF USED(.ALIAS) AND ATC("CURSOR",.BaseClass)#0 AND ;
       CursorGetProp("buffering",.ALIAS)>1
       IF !TableUpdate(.T.,.T.,.ALIAS) && update on exit
          THIS.CheckError()
       ENDIF
       * If your form has General fields, there is a possibility
  • Toolbar preferences

    After installing Visual Studio Service Pack 3, you must update the system toolbar preferences stored in the resource file, Foxuser.DBF. For example, if you have a distributed application that ships a Foxuser file containing a Print Preview toolbar preference that hides the Print button, you need to re-create this preference for the Foxuser file being used by the application.
