I use visual web developer. 

They are to the beginnings with asp.net. 
I am trying a code found on codeproject, practically a messagebox. 
Tried in local it works all but in remote I have some problem.  
Delivery with VWD then inserting one webform with the option separate code (aspx.vb) 
I insert my controls and code, I try in local.
it works.

I transfer in remote the DLL under the folder bin of dotnetnuke, put the files wf1.aspx and wf1.aspx.vb in root. 
I try and it does not work!! It says:   

Description:
An error occurred during the parsing of to resource required to service this request. Please review the following specific seemed error details and modify your source rows appropriately.   

Parser Error Message: Could not load type “wf1”.   
Source Error:   
Line 1: <%@ Page Language= " VB " AutoEventWireup= " true " CodeFile= " wf1.aspx.vb " Inherits= " wf1 " %> 
Line 2:  Line 3: <%@ Register Assembly= " msgBox " Namespace= " BunnyBear " TagPrefix= " cc1 " %>   

Then I have tried to create one new windowform wf2.aspx but without separated code, I insert the controls like in the previous one and the relative code, I transfer on the remote one and ...... it works.   
Wy  The code that gives automatically added create a error!  You would know to say to me like never?

Thanks, Alverman
