joeller :
The command line command “stsadm –o addsolution –filename WSPBuilderDemo.wsp” merely produces the error “command line error”, then lists all the possible operations for the command. “stsadm.exe –o addsolution –filename WSPBuilderDemo.wsp” and “stsadm.exe -help” produce the same thing.

This is the correct syntax. Please see the following technet page: http://technet.microsoft.com/en-us/library/cc288721(office.12).aspx – Is your WSP file name WSPBuilderDemo.wsp?

TerryR :

I tried to repeat this technique but did not succeed. My project, builds, deploys, and is available for activation. I activated it on a site then created a new list but the new control was not visible on the DispForm

Hey Terry,

Can you verify that your CompleteTask is a public class and that you have indeed used the correct assembly information in the elements.xml file? If the CompleteTask is not a public class, the SPLinkButton will not be visible on the DisplayForm. Are you using a task list? I ran through the tutorial just now and did not encounter any problems here.
