Changing Text in Files

[vninja]

Hi, i'm totally lost.

Im trying to create a program that reads a file and then changes some text in the file. i've got a couple approaches to this problem but i cannot find the resources nessesary for me to complete any of these. if anyone could help i'd greatly appriciate it.

So these are the challenges:
I:
Read from text file
search for specific words
replace (delete then add, etc.)
close file
send file to printer.

II:
open file
write the text to file including printer escape codes to bold and change txt
size and maybe txt font
close file
send file to printer

III:
open to suggestions on other approaches to this problem.

I found out how to open, close, write to, and print file but i cannoth find how to replace words.
the codes that i am finding on how to seek for txt i don't quite understand. if anyone could send an example i'd appriciate the help

Thx

Ok i figured out one part (which i can't believe my idioticy) for the text formatting. a simple approach of using html instead of txt file and using the html tags to format the txt for me. but now i need to know how to print the file ny1 any suggestions?

The problem in part II is that as stated you would need to know what the printer was as not all printers talk the same language.

Thanks that just totally sux. but isn't that why there are drivers to convert from comp lang to print lang? just wondering. i realized that its on a network under a static i.p. and its some kind of HP laser if thats not too vague

Oh there is (in Windows anyway but I would assume Linux has a way as well).

You create a printer DC (device context) and draw to that device context, then windows , the HAL and the printer driver sort out the actual printing.

It is however quite involved.

So you can just send the file to the printer you have to draw data on the printer device context.

Alternitively if the file is a text file or some other file with a recognised extension you can cheat and have Notepad do it for you by

ShellExecute(NU LL, "print", <FileName>, NULL, NULL, 0);
