The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Error accessing COM dll from ASP.net website on 2003 Server, but not XP

Asked by PhyllisSmith in Microsoft IIS Web Server, Programming for ASP.NET, WebApplications

Tags: asp.net VB, all, http://cs2.csmiths.com, System.Runtime.InteropServices.COMException (0x800A0005): Invalid procedure call or argument at Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object o, Type objType, String name, Object[

I have been developing an ASP.net application (VB in VS 2005) which uses a COM dll to provide some base functionality.  On the development box (Windows XP SP3), I can run the code both in the IDE, and also through IIS after publishing it.  On the test server box (Windows 2003 SP2), when I get to the first call into the COM dll, I get the following error:

 System.Runtime.InteropServices.COMException (0x800A0005): Invalid procedure call or argument at Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object o, Type objType, String name, Object[] args, String[] paramnames, Boolean[] CopyBack) at Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateGet(Object Instance, Type Type, String MemberName, Object[] Arguments, String[] ArgumentNames, Type[] TypeArguments, Boolean[] CopyBack) at auctShared.clsProject.FillDS(String Folder, DataSet myDataSet) in C:\Documents and Settings\phyllis\My Documents\Visual Studio 2005\Projects\AuctionV3Online\auctShared\clsProject.vb:line 19

I would sincerely appreciate any pointers to how to solve the problem.  I'm thinking it may be related to IIS version and/or configuration, but I don't kow how to fix it, and haven't had any luck searching for similar issues.  You can see the problem if you go to the referenced link, and click the Login button.

AuctDS is the COM dll.
