Greetings,

When trying to close a project (BCB6) I keep getting this error now:

Access violation at addresss 400058E8 in module 'rtl60.bpl'. Read of
address FFFFFFDD.

</error message>

It was just working fine, but I have seen this message before. Any ideas?

Thanks,

Tim Howard

p.s. I changed nothing since yesterday, came in today and the project
won't close.

Well I'm curious, but just so everyone knows I just killed it and opened
a new project through Explorer and everything is fine. This new project
closes..

oh well

If it's not one thing,

Access violation at address 008A377E in module 'vclx60.bpl'. Read of
address 0000021C.

</error message>

Hi Tim:

Usually this type of error is due to a badly behaved component, not the
actual IDE (by itself).

If you have installed any new components lately, try removing them and see
if the error resolves itself.

HTH,
Martin.

Ok, I rebooted and I'm still getting this message below. It seems to be
related to debugging gone horribly wrong?? I'm not doing anything crazy
besides setting some watches. Could that be causing this?

cheers,

Have you removed the Class Explorer DLL. that tends to cause most problems
in BCB.

I have not done this. How do I do it and will it effect the operation of
BCB any?

Thanks,

Tim,
Sorry to jump on your coat tails but...
I am having the same problem. I am tring to modify/fix an application that runs for a while (days or hours) and then gives a few error messages I have not been able to track down.

One of them is:
"Access violation at address 00403A66 in module 'clockdisplay.exe'. Read of address 00000008."

clockdisplay.exe is the application I am modifying.

The other messages are more vague.

"Compatibility not supported"
and
"Invalid parameter"

Both of these messages also occurr after a extended period of time. This app runs continuously. I figure the Access Violation is a memory issue, the others could be side effects.

Help or suggestions on how to track these down from anyone is welcome!

thanks,
Todd

First thing to try if you ever suspect memory problems is CodeGuard.
This will slow your application considerably, so you may not want to
run for hours! But even a small run will locate most problems, so long
as you exercise most the program functionality.

Vague, and seemingly inappropriate, messages from Windows can
mean creeping resource loss on Windows 98 and ME. If you are on
thoses OS's, you can use the resource meter to see if it is
constantly going down while your app runs.

If it seems to be related to just closing that one
project then try things like cleaning up IDE config
files like <projectname>.dsk.
If it seems related to running/debugging that one app,
then turn on use debug libraries in project options
and turn off use of packages. Then, if it's in your app,
debugger should automatically break in vcl or rtl source when
the AV's happen.

There is a DLL in the Borland install directory whose name I can't remember
but it includes an x and a c in the name
something like bcbclx.dll.
Just rename it and you will get a warning next time you boot BCB. Ignore
warning and it will get removed.
All you loose is the class explorer, all you gain is much better reliability

I have tried to use Code Guard. It fails immediately on my Test System when I run the app. I only get two lines in the log file.

This is running on XP Pro. Through Task Manager, I haven't seen memory resources dropping. The Access violation can actually fail immediately after a reboot.

What kind of failure?
That sounds like a good chance of finding your problem!!

Also, I tend to run CodeGuard builds through the IDE, as you get
something similar to 'break on exception' every time CG spots a problem.

The error I get on the Test System with CodeGuard turned on is:

Error 00001. 0x400000 (Thread 0x0460):
Exception 0xC0000005: Access violation at 0x0.

Isn't CodeGuard supposed to work if you run it in/on a NON-development evironment?

This is the contents of the .cgl file on my DEV PC when I run the app. Could it be something in Borland's code? OR something that the app calls to cause this as a side effect?

Yes it is, so long as the CodeGuard DLLs are available. I'm guessing
you have these in place, as you are getting a log file at all!

That error is more than a little wierd though. Have you tried running
through the debugger to see if that gives you any more hints where CG
is going strange? I'm clutching at straws now, admittedly. Remote
debugging is hard :? (
