Pass Parameters to an external appl when launched from web dynpro ABAP .

Question

I want to Pass Paramaters to an external application when launced from Web dynpro ABAP . I have successfully launched an .exe file ( Notepad / eViewHSEditor ) from Web dynpro using the logic from Standard WD_TEST_APPL_ACFEXECUTE component  But I am unable to Pass paramters to the .exe file .
example :-  I would like to pass parameters  text1 text2 in the arugement list and I expect it opens an untitled notepad and in the file it will have parameters text1 text2 . But it is behaving in a different way . Below are the detailed steps of what I have done .
The steps that I followed :-
1)  Right now I have created the white list Configuration for Notepad.exe
2) I have created 1 and 2 postions both of type string and permission Legal .
3) The Paramter Value is * for both 1 and 2 .
4) I activated the whitelist and it generated an .XML file
5)
          application = 'C:
WINDOWS
system32
notepad.exe'.
          argument = 'text1 text2' .
          co_element :- I am reading the element from the conrtext .
      co_element = wd_context->get_lead_selection( ).
      co_element_stru-attribute_name = 'ERROR'.
      co_element_stru-element = co_element.
      wd_this->acf_method_handler->if_wd_acfexecute~execute( application =  application
                                                             argumentlist = argument
                                                             errorinformation = co_element_stru ).
when i execute  the application , it is trying to launch a notepad with file  'text1  text2.txt'  and it doesn't have one , it is asking do you want to create .  If You yes, it will open notepad with name 'text1 text2.txt' . If you Pass abcd in the arugement list , if the file with name abcd.txt exists , it opens the notepad with that file name .

You try to open notepad from your PC with the same command, you will the same result.
start->run->notepad "test1 test2". You get the popup saying that "test1 test2" file is not existing. You can google it to find a way to pass the text while opening notepad and try to fit that in your WebDynpro argument. I doubt if it is possible though.
