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!

C# to Excel, long strings throw error when loading data

Asked by srinivas_vemla in Microsoft Excel Spreadsheet Software, .Net Editors & IDEs, Microsoft Visual C#.Net

Tags: excel, 0x800a03ec, from

I load an excel file using the ExcelApplication interop from C#. I do it by first loading an 2-D array with all my data and then selecting a range and setting:
range.Value2 = arrData;

This works great as long as the array does not contain any element with more than 255 characters. But once a long string is encountered, an error:

An error occurred please contact the adminstrator with the following information:

Exception from HRESULT: 0x800A03EC.

Stack Trace:
   at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)

   at Microsoft.Office.Interop.Excel.Range.set_Value2(Object )

comes. I can have more than 255 characters in my aarray. How can I fix this error?

Thanks
