mscorlib error

[alex002]

Dear all,

I have created an Ole Db provider in ATL COM and I have use vb, vc++ 6.0
to create some ADO clients to test. It work well. Now, I want to create a
vb.net client which will use ado to connect to the database. However, the
strange problem occured. I try the same query in 10 times without
connection closed; however, when it execute the query forth times, error
occured and the error occur in mscorlib and the error number is 91. I have
searched in web but no information about the error number. Can any one help
me to solve this problem? Thank you for all of your help.

Hi Alex,

What is the nature of the error number? Is it extracted from an HRESULT? Is
it what Windows API GetLastError() returns?

Have you also tried to run the provider under a debugger to see whether this
error is actually raised by the provider?
