I have VS2005 , DNN 4.3.7 and MSSQL and I need some advice on what I need to do to modify the site's registration process.
I downloaded an install version of DNN and installed it on a staging server. I have setup the pages in the dnn online environment.

I need to modify the registration code, which (I think) is on admin/security/register.aspx.vb
To test to see if I am in the correct place, I modified the private Sub cmdRegister_Click
from
'update the user
objUserInfo.UserID = UserInfo.UserID
objUserInfo.PortalID = PortalId
objUserInfo.Profile.FirstName = UserControl.FirstName

to
'update the user
objUserInfo.UserID = UserInfo.UserID
objUserInfo.PortalID = PortalId
objUserInfo.Profile.FirstName = "test" & UserControl.FirstName

(The last line has changed)

I then 'built' the page in VS2005 (CTRL + F5). I expected that when this new user was added to the database, the word 'test' would be added to the firstname. Instead the debugger panel gave me alot of errors (I guess problems already present). I tried the page in IE and nothing changed.

Am I totally off track here? I'm not very clever with asp.net.

I was thinking maybe I should have originally downloaded the 'Source' package. From what I gather, this has all the dnn assemblies and you have to compile them all to get the site working. Has this got something to do with it? I don't think I need to modify the classes etc, I just want to use them in a different way when the user registers.

Another idea was that the 'build' was not building on the staging server since I was getting so many errors. So in solution explorer I right clicked the website root (which is the staging server) , clicked 'property pages' and then set 'start options' to the http address of the website on the staging server.

Any suggestions?

Brian,
Users/manageUsers.ascx is the file that contains the registration function. I agree with what you say, and UCanUse Attributes is a great module and will perform this task.
Thanks very much :)
