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!

Feeding Crystal Reports with a dataset from .Net

Asked by PantoffelSlippers in Crystal Reports Software, .NET

Tags: Crystal Reports, VB.Net, Business Intelligence, BI, .Net

Hi experts,

I recently posted a very similar question but realised I need to go one step further.  I'm writing a VB.Net application with one or two Crystal Reports incorporated.  I'm using .Net framework 2 and VS2005.

My original question was:  how can I pass my crystal report (rpt) a datatable/dataset from my .Net code?  This was answered by the following: http://www.emoreau.com/Entries/Articles/2006/09/Feeding-Crystal-Reports-from-your-application.aspx

This works great if the dataset and XSD comes from a database.  But now I need to pass a dataset that does not come from a database.  I build the dataset and datatable within it by collecting data from other sources.  See example below:

            With ds.Tables("InstanceTasks")
                .Columns.Add(New DataColumn("ReportHeading", System.Type.GetType("System.String", True, True)))
                .Columns.Add(New DataColumn("InstanceName", System.Type.GetType("System.String", True, True)))
                .Columns.Add(New DataColumn("TaskCount", System.Type.GetType("System.Int32", True, True)))
            End With

I then manually populate it with data.

My problem is:  if I provide my crystal report with a XSD Schema written from this dataset, it doesn't show under ADO.Net Datasets.

Is there some other way to pass this dataset to my report?

Please help!
