Dears,

I have a form where I have components ppReport on the same.
After me to access the ppReport and to make some alterations, when I try to
save the unit generates the error:

"Access violation at address 04AB0AAA in module 'rbRCL77.bpl'. Read of
address 00000008."

I already deleted the form and I implemented a new form and the error
continues. How possou to solve this problem?

Thanks,

Hi Alessandro,

This is not a known issue with ReportBuilder. See the article below on
cleaning a corrupt installation of ReportBuilder so you can be sure no old
RB file are being used. I would also recommend upgrading to RB 7.04 and
testing with that. This is a free upgrade.

--------------------------------------------
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.

Dears,

I followed these steps and I updated for the version 7.04, however, the
problem persists...
A peculiarity of this form:

1. I have a form "base" in which I possess the components: ppReport,
ppDBPipeLine, ppDesign... We will call this form of: "Form_A"

2. I inherited a new form starting from the form "Form_A" in which I added
more two components: ppReport and ppDBPipeLine. We will call this form of:
"Form_B"

3. I inherited a new form starting from "Form_B", in which I really made the
drawing of the reports. When I try to save this new form, you happens the
error:

"Access violation at address 04AB0AAA in module 'rbRCL77.bpl'. Read of
address 00000008."

How can I solve this problem?

Thanks,

Hi Alessandro,

It is usually not a good idea to place a DBPipeline inside a form ancestor.
This is because the DBPipeline contains the AutoCreateFields property which
will not sync when using the descendent. You might try setting the property
to False and see if this helps. Otherwise you will need to remove the
DBPipelines from your ancestor form.
