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.

change crystal report access oledb location at runtime

Tags: vs 2005 vb.net asp.net
I want to run a crystal report in my vs2005 web application. It uses two Access databases that are related in the report. The problem is that I used oledb and at design time I had to set the databse location of one of them to the application's app_data folder that is under MyDocuments\microsoft visual studio2005\projects\yada yada yada since that is where it is when I am developing the app. But when it moves to the actual web server that will no longer be the proper path. How do I deal with this? The other database path is OK since it is the same path on both the development machine and the production one. How do I change the location either at run time with code or by setting the thing up at design time?

I have seen some sql server and oracle examples on Google using report.DataSourceConnections(0).SetConnection but it asks for a server name as well as a database name and I have no idea what the server name for an access database is. Also, what is the database name as opposed to the server name? Which one requires the full path in addition to the file name so it can find it? Is this even the thing to use?

This should be a lot eaiser.

You would think this would be a basic issue well-covered by the documentation since VS2005 runs its web sites on its virtual server using the project's file location which is never going to be the same as an actual web server.

So how do I do this, and remember I only need to change the location of one of the databases in the report.

I'm sorry, I'm sure you mean to be helpfull otherwise you would not have posted but saying a 591 page document covers my question doesn't really narrow things down much. I read through the table of contents and I could not see anything that covered ACCESS databases and what I did see had nothing to do with setting and changing the location. I allready have the VS2005 documentation, the crystal reports documentatin and the internet. I need some specific help here.

Give you a basic example here: Basically the Servername here refers to the location of your Access Database File. For web application, you can use Server.MapPath(Foldername)

  'Set the connection information to ConInfo object so that we can apply the
            ' connection information on each table in the reporteport
            ConInfo.ConnectionInfo.UserID = YourDBUserid
            ConInfo.ConnectionInfo.Password = YourDBPwd
            ConInfo.ConnectionInfo.ServerName = YourDBLocation
            ConInfo.ConnectionInfo.DatabaseName = YourDBName

            eReport.FileName = Path
            rptViewer.ParameterFieldInfo = eParameters
            eReport.DataSourceConnections.Item(0).SetConnection(eReportLink, DBName, DBUserid, DBPwd)
...
...
...


Hope it helps.

is YourDBLocation the full path including the database file itself or the full path to the folder containing the file?

The db has no user name or password. Do I put empty strings in there?

If I don't remember wrongly, Access connection for Servername should be including the database filename.

The default username for Access is "Admin",  give a empty string as "" for password if you don't have.
