Hi...i was wondering if there is a way to read line by line from an opened Notepad window....

i saw that readln does this but from a filename....

thanks...

ReadLn *does* read from a filename:

ReadLn>FILENAME,LINE_NUM,VAR_TO_STORE_LINE_IN

Hi brahama,

Do you mean you want to write a script that can read the text inside a Notepad window before Notepad has saved the text to a file? If so, read about the GetControlText> command in the Help file then, enter and save this script:

Code: Select all

GetControlText>Untitled - Notepad,Edit,1,npEdit

MDL>Here's the text in your Notepad window:%CRLF%%CRLF%%npEdit%

StringReplace>npEdit,%CRLF%,~,npEdit

MDL>Here's that text again only we've replaced all the CRLF pairs with a ~%CRLF%%CRLF%%npEdit%

- open a new Notepad window, type in 3 or 4 short lines of text but don't save the file
- run the above macro
- It will read all the text from Notepad and display it
- Click OK and it will display the text again, only CRLF (Carriage Return and Linefeed pairs) have been replaced with ~ characters. Did this just to prove that the CRLF pairs are there.

I don't think there is a convenient command or structure to just read in say... just the 3rd line... but since you can read the whole mess into a variable, you can then setup a loop to search through that variable, building lines as you go. Every time you hit a CRLF, you've read in another line so you could save that line in an array variable and when you had processed it all, you'd have all the lines loaded into the array. Want line three, its in linearray[3] or whatever you called it.

Hope this helped, take care.

Glad to hear. If you're willing to share your finished script, please post it here as it may be just the thing others are looking for. Also, quite often someone else may suggest an improvement that you may not have thought of.

Take care
