This file contains important supplementary and late-breaking
information that may not appear in the main product
documentation, and supersedes information contained in other
documents, including previously installed release notes.
Borland recommends that you read this file in its entirety.

IMPORTANT:  Delphi 8.0 must be closed before installing this

   - RTL
   - VCL



* Update 2 includes cumulative maintenance from Update 1.  You
  can install Update 2 regardless of whether you have
  installed Update 1 or not.

* You will need the original Delphi 8 installation media to
  install this update.

* This is a self-executing update.  Double-click the file to
  begin the installation and follow the prompts.

* During the update installation, the following dialog will
  prompt you to overwrite your existing bdpConnections.xml file:
    "Setup has created a new  file based
    upon the drivers you have selected for installation. Do you
    want to overwrite the existing copy of 
    file with this one?"
  You should choose "Yes," since the BDP version has now changed
  to If you want to preserve your existing connection
  information, you can choose not to overwrite the file,
  however, you must then change the version of the BDP
  assemblies in your bdpConnections.xml file from

* This update can not be removed after it is installed.


After installing this update, you might encounter the following

* If you encounter the following errors when starting the IDE:
    "Borland Data Provider. Specified cast is not valid."
    "Object reference not set to an instance of an object"
  delete the ApplicationSettings.xml in location '
  \Local Settings\Application Data\Borland\BDS\2.0' and restart
  the IDE.

* After installing Update 2, a new registry entry, "$(BDS)
  \Bin\Borland.Vcl.Design.Xml.dll" = "Borland XML Components" is
  added to HKEY_LOCAL_MACHINE\SOFTWARE\Borland\BDS\2.0\Known
  If you are starting the IDE for the first time after
  installing Update 2, the IDE automatically copies all the
  registry settings from HKEY_LOCAL_MACHINE to
  However, if you have already started the IDE once before
  installing this update, do one of the following to add the new
  registry entry to HKEY_CURRENT_USER:
  a)  In the IDE, choose Component | Installed .NET Components.
      In the dialog that appears, select the  .NET VCL
      Components tab and click Add.  Navigate to the Delphi 8
      installation bin directory, select
      Borland.Vcl.Design.Xml.dll, and click OK.
  b)  Close the IDE and use regedit to add a new string entry,
      "$(BDS)\Bin\Borland.Vcl.Design.Xml.dll" = "Borland XML
      Components" to registry key
      Assemblies and restart the IDE. Please read the WARNING at
      the end of this file before editing your system registry.
* If you encounter errors when compiling or running an
  application, delete any referenced assembly files which may
  have been copied into the project output directory.  For
  example, Borland.VclRtl.dll, Borland.Vcl.dll, and other files
  that are listed in the "References" node of the Project
  Manager for the project. You should also delete all files with
  .pdb or .dcpil extensions.
* If you encounter designer errors when opening an existing ECO
  project, delete any .dcuil and .exe files belonging to that
  project before opening the ECO project. Failure to do so may
  result in errors such as "DataGrid received an exception at
  design time. Please reset the DataSource and DataMember
  property on the grid."
* When using dbExpress MSSQL and TClientDataSet.ApplyUpdates,
  you may encounter either of the following errors while
  applying updates, due to a SQLOLEDB.DLL limitation:

    "Cannot create new transaction because capacity was exceeded."
    "Cannot create new connection because in manual or
     distributed transaction mode."

  To resolve the errors, use one of the following workarounds:

  - On the DataSetProvider Options property, make sure
    poFetchBlobsOnDemand and poFetchDetailsOnDemand are False.
  - Use a BeforeApplyUpdates event to either call CloseDataSets
    or Close the connection: 
     procedure TForm1.DataSetProvider1BeforeApplyUpdates(Sender: TObject;
       var OwnerData: OleVariant);
        // SQLConnection1.Close;
* To use Nevrona Rave Reports with Delphi after installing this
  update, you will need to download and install the latest
  update to Rave.  See the Borland web site for download

  error "Object reference not set to an instance of an object,"
  and access violations.
* The Escape key does not cancel the edit of a Text property.
* When saving a Windows Form application that has a global To-Do
  item, either an external exception or an access violation
