Visual Studio 2005 not happy with postgresql

Hi community!

Here is my problem:

* Postgresql 8.1 installed on windows XP (machine 1) with DB up
and running. I can access/change/see all my tables, etc with EMS
Postgresql manager
* On Machine 2 (windows XP) I've installed the pg ODBC drivers
8.01.01 and created a System DSN to machine 1
* I tested this DSN with MS Access, and I could see my tables, add
items, launch queries
* Now, I need to use Visual Studio 2005 (with .Net 2.0) for our
project and would like to be able to create XSD files visually (using
the VS2005 built-in tools). In VS2005 Server Explorer, I created a new
Database Connection, using the Microsoft ODBC Data Source (ODBC) with
the .Net ODBC Data Provider selected. Pointed the thing to my working
ODBC DSN and tested the connection
* Connection works (says VS2005)
* Now I have a new Data Connection in the Server Explorer, with 3
tree entries; Tables, Views, Procedures. My problem is that "Tables" is
empty, "Views" is empty but "Procedures" contains hundreds of postgres
functions.
* I would like to see my tables and views!

Remark:

* I tried OLEDB, whitout success either. VS2005 says that there
where "some" errors and that "no work could be done"... cool he?!

Can someone please help me, as I've lost already 2 days figuring out
what is going wrong here. I google nearly every forum about that..

Thanks in advance,

1. There is a lot going on with the pgODBC driver versions? You could try a different version.
2. You could try Npgsql -- the .NET data provider for Postgresql.
3. It sounds like you do not have a default schema of public -- I think that happened and/or was fixed in
one of the very recent version of pgODBC .

Dear Tobias,

I have the same problem with visual studio 2005. The beta's worked perfectly
but since the RTM version I'm experiencing the same.

Already filed this complaint to MS.

I have a schema public and meet all the previous requirements. So far I
haven't been able to crack this one and recoded my application to use npgsql
which has a commandbuilder but not the nice gui features.

In the postgresql log you actually see VS querying all the data (tables
etc.) but they simply don't display. Also the automatic generation of
update, delete and insertcommands does not work anymore.

Perhaps this helps.. (a bit ;) )

Cheers,

Paul

Hi Greg,

Thanks for replying!

- As I said, I'm using the latest version 8.01.01.01 and even tried the
8.01.01.00 version without success. What do you mean by "Try a different
version" ?

- How would I add a new .Net Framework Data Provider for Npgsql to
Visual Studio 2005 (I'm speaking about the Server Explorer GUI part, not
in code, which works)

- I have a default public schema, but it's empty, as I've created my own
one. I even tried to fill the public schema with a test table, in order
to check if it was pointing there. Not the case. I checked if there was
a way to "direct" VS2005 to the right schema. I tried using "Set
search_path to" in the connection setting (page 2 of the ODBC config
dialog) without success.

Any other ideas?

Thanks in advance for your help and best regards from Switzerland,

Hi,

i did not experience such issue but when i use ODBCConnection from VS.NET 2005 (VB.net in fact), in debug mode, my connection test works perfectly, but when i try to create a DB on-fly, my VB.net seems to freeze... around the same time, that the timeout s
ession is, and give me back the control displaying a message that connection has be closed....

but if i test my application in release mode, it works perfectly...

I suppose that VS.net ODBC connector has some issue with DB in debug mode....try your application in runtime.

HT,
Maileen
