asking permission

Probably, it is prohibited by IE's security option.

pls give vbs code to omit this

Try this:
http://stackoverflow.com/questions/128463/vbscript-clipboard

if i want to use notepad instead of word ,make changes required in following code.

' Set what you want to put in the clipboard '
strMessage = "Imagine that, it works!"

' Declare an object for the word application '
Set objWord = CreateObject("Word.Application")

' Using the object '
With objWord
   .Visible = False             ' Don't show word '
   .Documents.Add               ' Create a document '
   .Selection.TypeText strMessage   ' Put text into it '
   .Selection.WholeStory        ' Select everything in the doc '
   .Selection.Copy              ' Copy contents to clipboard '
   .Quit False                  ' Close Word, don't save '
End With

It is not possible to do it from notepad, because there is not application object for notepad.

I suggest you use a freeware utility called NIRCMD:
http://www.nirsoft.net/utils/nircmd.html

the you can use it to set the cliboard:
 
nircmd.exe clipboard set "Hello World!"

dear , i know in one of your experts answer he told me to close above permission. but when i asked him about the code to close that instead of manual way, i did not get response for long time. so i thought let me ask a fresh question.

anyway, i followed his idea and able to do it but again the question is still there. i want to enable "allow programmatic clipboard access" in scripting of internet security with vbs code.

pls help me to provide it.. can i do the same with registry dwrod key. ?

all three questions in the list I posted provide the answer to your question using registry settings or other way
but you ignored them and ask the same question 4th time ....
