Hi

I am using the latest Fb 2.1.1, D6 SP1 and Zeos 6.6.3 under Vista business

Here is my ZConnection settings:

  Protocol = 'firebird-2.0';
  TransactIsolationLevel = tiReadCommitted;
  Properties.Add('dialect=1');

Everything working fine when running the application (It's a DataSnap dcom server), but when the app is closing, it raise a AV error, here is the exception trace:

ExceptHandler(EAccessViolation: Access violation at address 01FF74A7 in module 'fbclient.dll'. Write of address 01ECEFC8, 01FF74A7) [01FF74A7] Unknown function at BLOB_edit

[005D02DA]ZConnection.TZConnection.SetConnected (Line 372, "ZConnection.pas")

It seems like something wrong with the driver settings, do I miss something?

Cheers,

Seems like an internal problem in fbclient.dll or ntdll.dll. Some incompatibility issue?

Without knowing anything about Blob_edit is very difficult understand what happened.

Anyway this function "RtlConvertUlongToLargeInteger" sounds like you are converting a longint to something. Do you know that dialect 1 does not support BIGINT? Because seems to me you are using it.

Or Are you sure your client is doing an update when server is disconnetting?

Thanks for your reply.

Yes, I am using Dialect 1 on FB2.1 But I don't think it's BIGINT problem because I never have this error when I was working with IBX.

I will do more investigation for this Blob_edit.

Cheers,

Tao
