How to enter login details manually while using DP automation?

[Uma]

Hi,
I am using DP Programming in my script.I asked to leave the userid and password colum as a blank one.(Instead of automation I need to keep that as a manual one)

Here is my script,
Here I am passing Uname and Pword value from text file.

Code:

'Browser("name:="&result,"application version:=internet explorer 7").Dialog("text:="&dia).WinEdit("attached text:="&usr1,"windowextendedstyle:=0","nativeclass:=edit").Set Uname
'Browser("name:="&result,"application version:=internet explorer 7").Dialog("text:="&dia).WinEdit("attached text:="&pwd).SetSecure Pword

How can I keep the Uname and Pword column as a blank one,I want to manully enter.

Any help?
Thank you,
Uma
