I'm having trouble with the following:
We have a 32bit Postgres Server here in the office.
I'm developing an application in Visual Studio 2013, in a 64bits Windows 8.
When I run the application, I get the following error:
ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application
I have both drivers installed (32 and 64 bits) for ODBC, but my 64bits driver, when I try to connect through VS to the server, it throws the same error as above, and only the 32bits driver can connect through VS.
In VS2013,I can see the Tables and configuration of the server, but when I run, more specific, in the Connection.Open() part, the previous exception is thrown.
Can somebody help me?
(Sorry about the English mistakes...)
Most Visual Studio application builds are 32-bit, even when installed on 64-bit Windows.
If your Visual Studio is 32-bit you must use the 32-bit ODBC driver for ODBC communication being done within Visual Studio its self.
You can (and must) still use the 64-bit ODBC driver when doing ODBC communication from 64-bit applications compiled in Visual Studio.
You could also be compiling and running a 32-bit application, even though you're on 64-bit Windows, in which case you must use the 32-bit ODBC driver with it.
Fun, no?

I am developing a Windows application that connects to Oracle DB.
The machine I am developing the application on has Oracle 6i installed with SQLPlus and Toad to access Oracle by command or graphical interface.
The same set up is true across all other computers in my work place.
The only difference is that my pc has Visual Studio and Oracle 10g ODP.Net libraries to make the development of Oracle Application possible using Visual Studio.
I made sure to include Oracle.DataAccess.dll file along with the EXE in the same path to reduce dependency on default paths/ etc.
The finished EXE file runs as expected on my computer, but whenever I publish it to the other computers, I get the following error message:
The type intializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception.
I tried to change the version of Oracle.DataAccess.dll from 2.111.6.20 to 10.2.0.100.
Again, it ran perfectly on my PC but gave the following exception on other PCs:
Unable to load DLL 'OraOps10.dll': the specified module could not be found.
I copied the said file above from my pc and included it in the published folder of the EXE but the same error message appeared, as if it invisible to the .Net application.
All computers have Windows 7 and all of them are 32bit.
Is there a way to make the application connect to Oracle regardless of the libraries or Oracle version installed locally on the computer? (The same way Toad works whether it detects Oracle 6i or 10g installed)?
I can't install the Oracle 10g ODP.Net libraries on all computers.
we are having a problem connecting to a PostgreSQL database. On one laptop we are using:
64-bit Windows 8
32-bit Visual Studio C# 2010
PostgreSQL version 9.0
64bit ODBC driver for PostgresSQL Unicode(x64) 9.0.1
On one desktop computer we are using:
64-bit Windows 7
32-bit Visual Studio C# 2010
PostgreSQL version 9.4
64bit ODBC driver for PostgresSQL Unicode(x64) 9.0.1
On the laptop, the typed datasets are working fine, but on the desktop, we get an error "Failed to call ODBC driver connection utility" when creating a typed dataset as well as "The specified DSN contains an architecture mismatch between the Driver and Application" depending on whether we use an existing connection string or try to test out a newly created one.
In both cases we are connecting to a machine data source created in ODBC beforehand. The machine data source itself tests successfully and has no problems connecting to PostgreSQL.
We are a bit at a loss as to what would make the difference otherwise than the version of PostgreSQL and what would be the best way to resolve this?
Thanks so much for the help!
I have Developed an Applicatoin in ASP.NET with C# and I have used oracle database.
my prob is when I am running this application from visual studio 2012 it will throw error like
Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64
bit mode with the 32 bit Oracle client components installed.
but when I host this application in my local iis and make application pool enable 32bit is true then it's working fine.
can anyone please guid me how can I run this from visual studio.
If it is just the ODP use the managed driver from Oracle.

I have folllowing things on my PC
Windows 7 (64bit OS)
Microsoft Office 2003
Microsoft Visual c# Express 2008
I have two projects on this system. In one project MS Access is connecting though Microsoft.Jet.OLEDB.4.0 provider, but in second project it gives error, says "Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine."
I need some help...
Thanks in Advance..
You have to compile your C# application to x86. "Any CPU" or "x64" is not an option since the Jet Ole DB driver/provider is not available for 64-bit systems, only for 32-bit.
microsoft visual studio opens my table using dataset designer
but i cannot open my table using the same connectionstring.
my database is DBase IV.
and this is the connectionstring
Driver={Microsoft dBASE Driver
(*.dbf)};collatingsequence=ASCII;dbq=d:\Data\88;deleted=0;driverid=277;fil=dBase
IV;maxbuffersize=2048;maxscanrows=8;pagetimeout=600;safetransactions=0;statistics=0;threads=3;uid=admin;usercommitsync=Yes
it is made by visual studio itself.
and this is my code
DataSet1TableAdapters.AN10TableAdapter _AN10TableAdapter = new DataSet1TableAdapters.AN10TableAdapter();
_AN10TableAdapter.Fill(D_Data.AN10);
and this is the error
ERROR [IM002] [Microsoft][ODBC Driver
Manager] Data source name not found
and no default driver specified
this real joke is killing me.
platform:vista x64
language:c#.net
.netframework vesion:3.5
worked on it:10 days
I guess the issue is the 64-bitness of your machine. The driver is an unmanaged component and you probably have a single version of it (32-bit or 64-bit) installed on your machine. Since you cannot load 32-bit unmanaged components in a 64 bit process (and vice versa), it'll not work. Switch the target CPU setting of your project to x64 and x86 to force the assembly to run with the appropriate bitness and retry. It's likely to solve your problem.
Do you have the dBase data sources installed?
Control Panel -> Administrative Tools -> Data Sources (ODBC)
System DSN tab
(My OS is Windows XP but that's the idea.)
