InfoPath Dev

I am new to Infopath...well, at least 2 weeks into it.  I am trying to understand how it interacts with project server and have been working with one of the codeplex solutions.  Unfortunately, I am getting this error both on my local (development) machine and in the document library in Sharepoint.  Has anyone come across this?  Thanks in advance. 

System.IO.FileNotFoundException
Could not load file or assembly 'Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.

 well it seems you are using object model to connect, that i will work only on the machine that has sharepoint installation.

 Hey



does that mean that web-enabled forms wont work on PCs when opening the infopath webform? E.g. people from outside wanting to open a webform and fill it and send it to the sharepoint server?

Hi, you have to replace your code that refer to server object model by code who call web services.
