Exception EAccessViolation in module VCL40.bpl

[timeslice]

Hi everybody,

When users are working in a Delphi4.0 based app, the following message appears:

"Exception EAccessViolation in module VCL40.bpl at XXXXXX. Access violation at address XXXXXXX in module 'vcl40.bpl'. Read of address XXXXXXX"

That is a constant behavior of the app, and usually hapens when the app try to open a form. Any clues, someone? All answer will be welcome.

Thanks and regards to all,

Marcelo Palenzuela

Does the address have a lot of 0's in it. Common problem : maybe, you're trying to open a form that hasn't been created yet or dispose/free something that has already been freed.

One of the messages:

"Exception EAccessViolation in module VCL40.bpl at 00003BCC. Access violation at address 40003BCC in module 'vcl40.bpl'. Read of address 0C69B4C8"

So, it´s the case mentioned above? If yes, there is some patch or fix (i don´t have the fonts of this app, it´s a commercial software) to avoid this error?

Thanks,

Marcelo P.

Looks like you have run into a bug the developer didn't remove. The only way is to go into the code, trace the error and remove it.
Like Weez stated, the program does some illegal operation. This has nothing to do with delphi, but with programming. Steven van Els

If you have the source to the application and can reproduce this error. Just open the project and run the application through Delphi with the debugger on, see if Delphi points you to the line that causes this.
