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.

Can't debug VB6-COM-DLL - How to totaly remove an Excel-COM-AddIn

Asked by Datenkultur in Windows ATL / WTL / COM Programming, Microsoft Excel Spreadsheet Software, Windows OLE Programming

Tags: VB6, Excel, COM, AddIn, DLL, Debug

I developed an Excel Com Addin. In the past I was able to start the dll in vb and debug it, if excel uses the dll. Suddenly it was impossible. It seems to me, that the dll wasn't used from excel at all, if i start the dll inside vb6 (The addin creates menus in excel. They only appear, if I the vb-project is not running).

I cleared the registry and cleared multiple versions of the dll but nothing fixed the problem. I tried to create a total new dll killing the binary compatibility, but it didn't  help as well.

Installing a new PC will work, but this will take a lot of time.

Edit: I use the DLL  not only with Excel. Starting it with another application (MS Dynamics NAV) debugging works fine. So it seems to be a bug in the regisrtration of the COM-DLL inside Excel. Does anybody know how to clear every registration-information about COM-AddIns in Excel? The Addin uses an IAddinDesigner to connect. Excel uses automaticaly the dll if I compile it again. After reinstalling Excel the COM-AddIn information was still there.

Any ideas?
