SQL Server 2005 integrated security

I am using Crystal Report 2008 and SQL Server 2005.

I use: myconnectioninfo.integratedsecurity = true

and the screen pops up with a login page when attempting to access SQL Server. Is there a way to put the user's login credential in visual basic so there is no login prompts?

i.e.

myconnectioninfo.userid = XXXXX

myconnectioninfo.passowrd = xxxx

for all users?
