Question

Imports Statements Broken

Asked by: NigelRocks

Experts,

I have a .dll that I'm referring to in my main project with two Imports statements referencing its contents.  After updating that .dll and rebuilding it successfully, I get the following error:

"namespace or type specified in the Imports BaseCommon.BaseCommonBAL doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliaes"

Nothing has changed about the .dll code and it worked about 15 minutes ago.  Ideas?

remove the DLL reference and readd it.

 

by: NigelRocksPosted on 2009-10-22 at 07:28:40ID: 25634615

I've done that three times already and it didn't make a difference.

 

by: wrmichaelPosted on 2009-10-22 at 07:29:57ID: 25634632

Is it a VB6 DLL?

If so see this:

The two earlier responses might be the cause, but another possibility is related to the interop assembly.  An interop assembly is generated by the IDE when you added the reference.  This is a managed assembly that exposes the types from the DLL that are consumable in a .Net application.  If you change any of you public type signatures, then this DLL will need to be regenerated.

If you'd like to automate this process, take a look at the documentation for TLBIMP.  This is the tool that the IDE runs to generate the DLL.  You can find it in the SDK folder on your machine.  (Something like: C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin)
I hope this helps.

It's VB.NET.  I'm left wondering why all this wasn't necessary before when it was working.

Could you have duplicated a variable name?

The Microsoft article covers Resolving a "Reference When Multiple Variables Have the Same Name".

It is worth checking.

Do you use source safe?

If so can you compare to your last version of the DLL?

 

by: NigelRocksPosted on 2009-10-22 at 08:13:48ID: 31644527

D'oh!  The problem was that I was adding and removing the dll reference from the wrong project in the solution.  However, you gave very usefull suggestions.

I just cleared my solution of all extraneous projects.  WAY too confusing.

Thanks!

Glad you got it fixed.
