Hi,

I have a requirement to call NOTEPAD.exe and call a TXT file from one local directory and save it in another local directory.

How to do this?

Thanks

You have to create an external command in SM49 which calls notepad.exe . Then from the ABAP program, use function module SXPG_CALL_SYSTEM to invoke the command.

If you would like to open a .txt file using notepad, all you need to do is this. Then you can save where ever.



call method cl_gui_frontend_services=>execute
   EXPORTING
     DOCUMENT               = 'c:file.txt'.

Is this what you want? Or do you want to save in another directory automatically?

If you simply want to copy the file without opening it, you can do this.



call method cl_gui_frontend_services=>file_copy
  exporting
    source             = 'C:file.txt'
    destination        = 'c:sapfile.txt'.

Hi Rich,

I need to save automatically to another directory, User interaction is not needed. and also i need not use FTP to move the file.

Hi Rich,

Why i tried to use NOTEPAD.exe and save to another directory is of formating. Initially TXT files are not formatted by using NOTEPAD.exe and save i am getting proper formated text. But simply copying the files formatting not happended properly using "frontend->file_copy"

Thanks

Well, then you can use the FILE_COPY method of the class CL_GUI_FRONTEND_SERVICES. See the post above. It's that simple.

I'm curious, what is the formatting that is happening when opening in notepad and saving?

What if you were to upload it and download it, would the formatting happen then?



report zrich_0001.

data: istr type table of string.
data: str_file type string.

parameters: p_file1 type localfile default 'C:file.txt'.
parameters: p_file2 type localfile default 'C:sapfile.txt'.

str_file = p_file1.

call method cl_gui_frontend_services=>gui_upload
  exporting
    filename                = str_file
  changing
    data_tab                = istr.

str_file = p_file2.

call method cl_gui_frontend_services=>gui_download
  exporting
    filename                = str_file
  changing
    data_tab                = istr.

Hi Rich,

We had a customised NOTEPAD.exe (written a new notepad.exe in Visual C++) that truncated the txt string to 132, and special characters get converted while saving.

I see, so in other words, you must open notepad in order to have the formatting happen. So if that is the case, you can use the EXECUTE method that I mentioned above, but the user will need to save it to the directory. I don't think that you can manipulate Notepad via OLE programming.

oops I misspelled the paramters while typing here

param = '/c YNOTEPAD.exe c:\test1.txt > c:\temp\test1.txt'.

I am giving like this way

param = 'c:\YNOTEPAD.exe c:\test1.txt > c:\temp\test1.txt'.

Thanks

If I understand correctly, you want to pass the contents of c:\text1.txt as input to c:\YNOTEPAD.exe and capture the formatted version into c:\temp\test1.txt.

It sounds like your YNOTEPAD program is still a text editor and that the formatting occurs on the save. The addition of "> c:\temp\test1.txt" is used to capture standard output. Unless the command line execution of "c:\ynotepad.exe c:\test1.txt" generates standard output, the "> c:\temp\test1.txt" addition won't work.
