Unable to load OraOps10w.dll:Invalid access to memory location

[Tracy]

I have been working on OpenAccess with Oracle for about a year.

Soem days ago, I noticed that the visual designer throw the exception:
Unable to load OraOps10w.dll:Invalid access to memory location




In the programe runtime,  also exists the same exception. for example:

Sunny.Model.Person person = new Sunny.Model.EntitiesModel().People.First();

run the code above will throw the same OraOps10w.dll exception.

But, I found that reference the Oracle.DataAccess.dll and read data from database outside OpenAccess without any exception.

Even more incredible is that if open a OracleConnection before the OpenAccess operation:

new Oracle.DataAccess.Client.OracleConnection(connectionString).Open();
Sunny.Model.Person person = new Sunny.Model.EntitiesModel().People.First();

the code will run without any exception. but I can not find a solution to solve the exception throw from the visual designer.

I have tried to reinstall "Oracle Data Access Components 10", grant all permission to everyone to the oracle directoy, and update the OpenAccess to the latest version, and so on... but the exception still exist.

Thank you for any help in advance!

Hi Tracy,
You said you are working with the Product for about a year. What has changed recently on your machine? Was everything working before? Have you upgraded your project to a newer .NET version?
According to this information, have you referenced the assemblies that match your .NET framework version?

To provide more help on this, can you elaborate a bit more about your environment? Which Oracle Client are you using? Which architecture is your project? x86 vs. X64. Which Visual Studio are you using?

I am looking forward to hearing from you soon and getting this solved with you.
