Automation USER ID/ PASSWORD using DOS batch files

Hi,

Hope somebody can help me.

I am calling an application's exe file inside a DOS batch (.bat) and provide the password when the application launches, by typing manually. But I want to include the User Id and Password INSIDE the same Batch file ( .bat)  and avoid typing  credientials manually.  How can do this in DOS   ?  (or even in VBScripts or Powershell. )
