Description

if the database= part of the connection string exceeds 256 characters an attempt to open the database gives the following error:
"Connection open failed. unrecognized database parameter block
wrong version of database parameter block"

I have only tested it where the database is in the form of "localhost:c:\...."

I have only tested it with an Interbase 7.0 connection,

256 sounds like a lot of charcters to exceed but when the path start with C:\Documents and Settings\xxYourProfilexx\My Documents\Borland Studio Projects\ it all gets used up very quickly.

Steps to Reproduce:

create a database with a long path
Add a interbase connection in C#B's data Explorer to your database.
use the Test Connection button.
If the path is 256 characters or less it is ok.
The supplied error message occurs for paths > 256 characters.

How did you create a path > 256. Creating directories to reproduce the bug NT doesn't allow me to create path > 246.

Need steps to reproduce the bug.

I am using XP Pro.

Maybe C#B build the path for me ?

I am on XP Home at the moment. I can build a path of 244 characters.

I can then lengthen one of the directories in the middle of the hierarchy by renaming it so that my path length is over 256 at the terminal end. I can still access objects at the terminal end.

Maybe this is how I did it.

I guess that the "localhost:" has to be handled in there too.
