Re-2: [Firebird-odbc-devel] Blob fields: wrong behaviour

[<woe...@ml...>]

Hello Paul,

first I want to apologize for my non-working modifications. Since I only have a MSVC 5 Personal Edition which refuses to compile the sources because of statically linked MFC, I did not and still do not have any possibility to test my changes. I already received feedback from one who had the same problem, but we could not solve it. Sorry that I did not inform you at once that there is a compiler error in my changes - I thought you were the ODBC driver developer and can handle that.

So for now I already have tried to "organize" a Pro compiler edition to be able to test my changes before submission - maybe I get one in a few days, and then I hopefully can solve the problem and test the driver. Hence I would like to suggest that someone maybe should make the ODBC driver dynamically linked to MSVC - if this is possible with little effort - so that it can be compiled with the Personal editions of Microsoft's compilers. 

Regards,
  Michael Woecherl

I've been going through your bug fix and I've found that it doesn't compile. The error appears to be associated with these two lines:


OdbcStatement::setValue (line 435)

  strcpy ((char*) binding->pointer, string[binding->blobCounter]);


OdbcStatement::setValue (line 440)

  memcpy (binding->pointer, string[binding->blobCounter], len);


The compiler wont accept them without a type cast. So far I've tried this kind of cast:


  (const char *) string[binding->blobCounter]


which the compiler accepts. Unfortunately a run-time access violation is then generated.


If you have any suggestions I'm happy to try them. I'm not the developer of the driver - just the maintainer of the source.



Paul
