Hello,

I installed both DotNetNuke_04.05.01_Source and Survey_04.00.70_Source.zip successfully. There is no errors when build the whole solution and website.

But when I build the three pages (Survey, EditSurvey, Settings), I have the following 11 errors:

Error 1 Object reference not set to an instance of an object. C:\DotNetNuke3\Website\DesktopModules\Survey\Settings.ascx 1 
Error 2 Validation (XHTML 1.0 Transitional): This name contains uppercase characters, which is not allowed. C:\DotNetNuke3\Website\DesktopModules\Survey\Settings.ascx 3 8 http://localhost/DotNetNuke_2/

Error 19 Validation (ASP.Net): Attribute 'resourcekey' is not a valid attribute of element 'ListItem'. C:\DotNetNuke3\Website\DesktopModules\Survey\Settings.ascx 30 19 http://localhost/DotNetNuke_2/
How to solve those errors especially the one (Object reference not set to an instance of an object)?

Thanks!

As Michaels says, they're only warnings that the presentation pages (ascx) contain non-xhtml standard markup. These show up when you have the ascx page open in vs.net as it runs a background compiler on open pages so that it can highlight potential validation errors. You can disable this warning by right clicking on the ascx, going to "formatting and validation", clicking on validation and unchecking "show errors" . Note, theres a known issue in vs.net 2005 where this setting does not save unless you switch to design view. I'd recommend you ensure you have service pack 1 installed as it fixes this issue amongst many others.

Did you close Visual Studio and re-open it? The error should go away. Also the module should still run fine. Another option is to install it using the install version of DotNetNuke. See:
