Start-Debug-Error: Access violation at address ... in module 'Vcl50.bpl'.

[Roland Fuchs]

Sometimes when i start the debugger (F9), I get an error box:
Access violation at address 40003C6C in module 'Vcl50.bpl'. Read of address
444E4128

When I want to restart the compiler or debugger I get the message:
Debug session in progress! Terminate?
-> Yes does not help!

Then i must kill BCB via the Taskmanager then i get following eror:
Acesss violation at ... in module 'bordbk51.dll' Read of address ...

I use BCB 5.0 (without any patches) on W2000

Does anybody know whats the problem?

Roland,

I don't guarantee this will work for you but the following often
helps:

This is pretty much a standard problem. By massaging the IDE you can
rid yourself of a majority of these crashes.

Close Builder and open 'regedit'. Open the following key:

HKCU\Software\Borland\C++Builder\5.0\Known IDE Packages

Remove or move the following two entries:

$(BCB)\Bin\bcbcxp50.bpl
$(BCB)\Bin\direct50.bpl

The first is the class explorer ... the package is a good idea but
very buggy. The second is C++Builder Direct. You can alternatively
disable both of these in the IDE under "Tools | Environment Options"
but I find it better to remove the packages completely so that the
IDE never even loads them.

Next, head to "Tools | Editor Options > Code Insight". Turn off
'Code completion', 'Code parameters', and 'Tooltip symbol insight'.
The first two can still be accessed by pressing 'CTRL+SPACE' but you
will avoid some downtime by turning them off from the start.

Lastly, unfortunately the Project Manager does cause a few problems
during debugging and compiling. I use it with very few problems but
some people have decided to stop using it completely. If you
continue to have problems during compiling and debugging you might
consider only loading 1 project at a time and stop using the Project
Manager.
