set reference to an instance
I have a page where I add records using 36 six textboxes. I have an if else statement where if the textboxes are blank an error message should appear but if they are all completed they are cleared after the data is submitted. When I add some information in all the textboxes and submit it the textboxes clear like they should but when I leave them blank it and submit I get an error message that states:
Object reference not set to an instance of an object.

To prevent problems with 3rd party software referencing core DNN assemblies, please change the references for DotNetNuke.WebControls and DotNetNuke.WebUtility to be project references rather than file. This way, all DNN assemblies reference the same version of DotNetNuke.WebControls and DotNetNuke.WebUtility.
P.s. I can provide the entire file, if necessary. Otherwise, I have attached the diff, for DotNetNuke.vbproj, to make this change:

Suggestions would be greatly appreciated.
And all this becuase installing 1.0.10c on top of 1.0.10 sucks, with no-one willing to give clear direction on how to do it poperly (ie results in an installation that is not broken, yet still gets the required rubbish deleted and the fixes installed :(

My best guess would be that when the form is being submitted, it requires certain information that it cannot locate because that information has not finished loading, and is therefore null.

Hello all,In visual web developer, the .mdf files where showing up in the database explorer until 2nd of march. But now it is not visible there.

With ASP.Net in the 1.1. framework, I commonly created web site solutions that contained a project for web pages, and a separate assembly project(.dll) for business objects. The web project would reference in the business object .dll. The business object project had an app.config file in which I contained a dynamic reference to a web service (typically for database access). The reference needed to be dynamic, so that I could change the reference for different deployments simply by changing the entry in the config file.
In the ...Set 2 variables equil without setting reference
Hello. I have 2 instances of a class object. One holds the data retreived from the database (it's a silverlight project) and the other holds the updated information as the user enters data into the form. The problem I'm experiencing is when I update the hold variable, with the fresh data, the variables are setting instance equality instead of just updating the variables. Is there some way that I can set class object value equality at a highlevel such as obj1 = obj2 or do I have to go into each elemental level such as obj1.person.name = obj2.person.name?
