Chart in RB does not pick up data source

edited February 2002 in General
With Delphi 6.0 and RB 6.01, neither TChart nor TDBChart within RB will pick
up any data sources. Data sources were configured some months ago, and
everything works fine unless I attempt to set up a new chart or alter an
existing chart. Charts on the main form work as usual. Am I missing
something here? I am not aware that anything has changed since these were
set up.

In a ppTeeDBChart, the data source is dataset, and the dataset can be chosen
from a drop down menu, which contains several datasets. Now the dataset drop
down is empty. In a ppTeeChart the data source is function, and the
function is set to copy. All available series then should appear. They do
not.

The library path in environment is was set to RB\Lib, and was expanded to
inculde RB\source, RB\TeeChart\Tee60 and RB\TeeChart\Tee66. RB Standard,
Sample, and TeeChart 5.0 components are installed under project
options/packages, and build with run time packages is checked with packeges
teeui;teedb; tee; and teeqr included.

Many thanks,
Tore Fossum

    You can only use one TeeChart wrapper component at a time (i.e. you can't
    load D6 support for both 4.04 (60) and 5.02 (66) at the same time.) The
    quickest way to resolve this problem is probably to complete the corrupt
    install directions included below.

    When you re-install RB, the installation program will automatically install
    the correct TeeChart wrapper packages.

    Article: Cleaning up a Corrupt Installation
    --------------------------------------------

    If you have been advised by Digital Metaphors technical support that you
    may have a corrupt installation, or if you are having difficulty
    installing, compiling or running applications after a ReportBuilder
    install, then it may be necessary to manually remove all ReportBuilder
    files from your system. Corrupt installations usually result when you
    are installing over a previous version of ReportBuilder which was not
    installed into the default directory, which was recompiled from the
    source, or when ReportBuilder files were manually moved from the default
    install location. Cleaning up a corrupt installation, consists of
    locating all ReportBuilder related files, and deleting them from your
    system. The first step is to use the uninstall program to remove as
    much of ReportBuilder as possible.


    Run the uninstall program

    1. Exit Delphi, and all other applications. You should have no
    applications running except the uninstall, otherwise you may lose some
    of your work.

    2. Select Start | Settings | Control Panel from your Windows desktop.

    3. Double-click the Add/Remove programs icon.

    4. Locate the version of ReportBuilder you wish uninstall and
    double-click it.

    5. The first page of the Uninstall Wizard allows you to choose between
    an Automatic or Custom uninstall. Choose Custom and click the Next
    button.

    6. Click the Select All button, then the Next button. Repeat these
    steps until you reach the last page of the wizard.

    7. Click the Finish button. All of the items you selected will be
    removed from the system.

    8. After all the ReportBuilder files are removed, you may be prompted
    to reboot the system. If this is the case, reboot the system.


    Delete the ReportBuilder root directory (and all subdirectories)

    1. Using the Windows Explorer, locate the ReportBuilder root directory.
    The default directory is:

    C:\Program Files\Borland\DelphiX\RBuilder

    2. Once you have located this directory, inspect it. If you have any
    custom work in this directory which you would like to keep, move it to
    another directory.

    3. Delete the ReportBuilder root directory.


    Delete all remaining ReportBuilder files

    1. Using the Windows Explorer, search the entire hard drive for all
    occurrences of:

    dclRB*.bpl
    dclRB*.dcp
    rb*.bpl
    rb*.dcp

    2. Delete any occurrences which correspond to the version you are
    removing. All packages are named with the convention NN, where
    the first number is the ReportBuilder version and the second number is
    the Delphi version. Thus, a typical package name for Delphi 5 would be
    rbRCL45.bpl. The same package for Delphi 4 would be: rbRCL44.bpl.
    Check Installing ReportBuilder for a list of the packages associated
    with each version.

    3. Using the Windows Explorer, search your hard drive for all
    occurrences of:

    pp*.*
    da*.*
    ra*.*

    4. These are the prefixes used by individual ReportBuilder units. 'pp'
    is used for ReportBuilder units, 'da' is used for DADE units, and 'ra'
    is used for RAP units. Depending on which ReportBuilder you have
    (Standard, Professional or Enterprise) you may not have all of these
    unit types.



    Additional Notes:

    1. Never have Delphi running when installing ReportBuilder.

    2. All ReportBuilder related files should be stored in the root
    directory $(DELPHI)\RBuilder.

    3. All ReportBuilder run-time packages should be stored in the
    Windows\System directory.

    4. You should never have ReportBuilder files in Delphi\Lib, Delphi\Bin
    or Delphi\Projects\Bpl.
