Folks,

One site I administer has gotten unstable. I am not sure whether it is this particular site or the hosting server (Godaddy Shared). The site works for a while and then goes down. Today I am getting the following

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 

Compiler Error Message: BC30002: Type 'IDataReader' is not defined.

Source Error:

Line 46: ' all core methods defined below Line 47: Line 48: Public MustOverride Function GetSurveys(ByVal ModuleId As Integer) As IDataReader Line 49: Public MustOverride Function GetSurvey(ByVal SurveyID As Integer, ByVal ModuleId As Integer) As IDataReader Line 50: Public MustOverride Function GetSurveyResultData(ByVal ModuleId As Integer) As IDataReader

This seems to have started after I installed the Survey module a month ago, but I can't say for sure. I know the problem has been much more prevalent in the past month. Any suggestions? I'll try and un-install the module if I can get back in. Is there a file I can uninstall from the site directory that might help?

Thank you for your assistance.

Doug

Hello Sebastian'

The site is running DNN 5.05 and the Survey module is version 4.6. The site version was upgraded in early December before installation of the survey module.

No problem on the wrong name - it's an honor to be mistaken for Sebastian.

The error is being caused by the just-in-time compiler failing to resolve a reference to the IDataReader interface in the file App_Code/Survey/DataProvider.vb. Why this is happening I'm at a loss at the moment as I have intentially tried several ways to break the reference in a 5.05.00 DotNetNuke install without being able to reproduce the error. Let's try the following starting with #1 then proceeding to the next one if necessary.

1. Force an application restart by making a minor modification to web.config file (i.e. a space added at the end of a line) then re-saving and if necessary re-uploading the web.config file back to the server. If the error clears following the forced restart and you are able to log-in to the site as host user, check the Admin-->Event Viewer for related errors and watch for a re-occurance of the error.

2. If that does not stop the compilation error, edit the file App_Code/Survey/DataProvider.vb replacing all occurances (4) of

IDataReader

with

System.Data.IDataReader

and re-visit the site to see if the error has resolved and you are able to log-in.

3. Finally, if that modification does not work, delete all files from the folder App_Code/Survey and re-visit the site. If you are able to log-in as host user, go to Host -->Extensions to delete the Survey module and watch the site and the Event Viewer for a re-occurance of similar errors in other modules or core code.
