Figure out access violation in Dsmtoolwindow.GetPreferences

Posted by jpluimers on 2021/05/26

Access violation when loading the Delphi IDE

Got the below error on Delphi 10.2 Tokyo with ODAC trial from DevArt at Delphi startup time (Error: Access violation at address 188F3528 in module 'DataSetManager250.bpl'. Read of address 00000000.).

My guess it is some configuration prerequisite which – when not existing – is handled very ungracefully.

This might have to do with my installation being a non-administrator Delphi user, but the ODAC installation requiring UAC elevation to administrative level.

In short this means the installing user is different from the user that runs Delphi.

Related (indicating it was fixed years ago, but apparently isn’t) via dsmtoolwindow.getpreferences – Google Search:

Workaround is to unregister the DataSetManager250.bpl package, though I have to figure out what functionality that disables.

Solved the access violation

Notes:

  • %APPDATA% points to %USERPROFILE%\AppData\Roaming (where usually %USERPROFILE% is on the %HOMEDRIVE%)

Fix script (the double backslash \\ is needed, otherwise the final double quote " becomes part of the path name):

setlocal
:: 19.0 is the version for Delphi 10.2 Tokyo 
set ProductVersion=19.0
reg add "HKEY_CURRENT_USER\Software\Devart\DataSetManager\BDS\%ProductVersion%" /v "ConfigFilePath" /f /t REG_SZ /d "%APPDATA%\Embarcadero\BDS\%ProductVersion%\\"
endlocal

This allows for an XML file named DataSetManager.cfg to be created in the ConfigFilePath directory.

Even though Process Monitor will show access to the below keys, there is no need to add any values there:

  • KEY_CURRENT_USER\Software\Devart\DBMonitor
  • KEY_CURRENT_USER\SOFTWARE\Devart\ODAC
  • HKLM\Software\WOW6432Node\Devart\ODAC
  • HKLM\Software\WOW6432Node\Devart\Odac

Deploy enough BPLs

Another thing when running ODAC trial and licensed applications

---------------------------
ODAC
---------------------------
%1 is not a valid Win32 application
ODAC Trial version needs additional "bpl" files to be present on the user PC.
If you build your project without run-time packages you need:
  dac250.bpl
  odac250.bpl
---------------------------
OK   
---------------------------

This message is incomplete; what it should say is that any BPL dependencies must be deployed. One way to find out about those is to use I wanted to know the loaded DLLs in a process like Process Explorer shows, but from the console: Sysinternals ListDLLs to the rescue.

Another way is to use TDUMP (see [WayBack] TDUMP.EXE, the File Dumping Utility) and search for the import tables. I did just that for the 10.2 trial; below is the full list.

There is way better documentation at Devart ODAC Deployment: Deploying Windows applications built without run-time packages which fails to properly archive in the WayBack machine (it gets into a redirect loop) so I quote it in full:

Deploying Windows applications built without run-time packages

You do not need to deploy any files with ODAC-based applications built without run-time packages, provided you are using a registered version of ODAC.

You can check your application does not require run-time packages by making sure the “Build with runtime packages” check box is not selected in the Project Options dialog box.

Trial Limitation Warning

If you are evaluating deploying Windows applications with ODAC Trial Edition, you will need to deploy the following DAC BPL files:

dacXX.bpl always
odacXX.bpl always

and their dependencies (required IDE BPL files) with your application, even if it is built without run-time packages:

rtlXX.bpl always
dbrtlXX.bpl always
vcldbXXX.bpl always

Deploying Windows applications built with run-time packages

You can set your application to be built with run-time packages by selecting the “Build with runtime packages” check box in the Project Options dialog box before compiling your application.

In this case, you will also need to deploy the following BPL files with your Windows application:

dacXX.bpl always
odacXX.bpl always
dacvclXX.bpl if your application uses the OdacVcl unit
odacvclXX.bpl if your application uses the OdacVcl unit
crcontrolsXX.bpl if your application uses the CRDBGrid component

From those posts and the below full list, you also need to deploy the bold dependencies:

  • dac250.bpl
    • rtl250.bpl
    • dbrtl250.bpl
  • odac250.bpl
    • rtl250.bpl
    • dbrtl250.bpl
    • dac250.bpl

Enabling your projects to use ODAC packages

To get around errors like "E2202 Required package 'odac' not found", you need to ensure the correct .dcp files for ODAC are referenced.

Unlike Delphi, the ODAC .dcp files contain a version number, so in your required packages list, ensure you add them not like rtl;dbrtl, but like dac250;odac250.
