I need a way to read all the rows in one column from an Excel file that the user picks from a fileupload control. I tried saving the excel file on the webserver with the upload control and then opening it with a OleDbConnection but that fails when running it from the webserver and gives the error:
Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
This works fine when just running it localhost, so i figured it might be a problem with security level at the webserver which i cant change. Instead i tried doing it with a streamreader direct from the fileupload control and because theres no need for saving the excel file on the server, but im not sure how to query the rows i need this way.
This is a very common error as evidenced but the very large number of problems and suggested solutions on the web. I finally got around it last week but can't remember what was the step that did it. At that time, I was building a web application rather than a web site. Is that the difference? As you can see, it is no longer in the APP_DATA folder and is named membership.mdf rather than aspnetdb.mdf. I ran aspnet_regsql.exe to create it and actually had it working and was updating it successfully. But for other reasons, I had to scrap the application and decided to re-create it from scratch as a web site rather than a web application. I had been using Visual Studio 2008 to build the web application but am now using Visual Web Developer 2008 Express Edition to build the web site. Unfortunately, the Visual Studio application will no longer open so I can't verify that the web application still works. Can anybody help? (Please!!!) BTW, ASPNET and NETWORK SERVICE both have full control over the membership.mdf.
I'm downloading a binary file from a SQL database to a client machine and want to instead download it to a folder on a server. THe code I'm using is below.
