vc++, graphics related problem..please !!!

[Mahesh Kumar. R]

hello everybody, i'm new to this group and also new bie to vc++. i
want to develop a parser like program which can able to identify the
predefined wordings -> windows control events(vc++).
example :
if the user write like this in text file(config.file).,
/* user defined file */

@DRAW MYLINE LOC
@LOAD BITMAPP SOURCE ...
@DISPLAY TEXT LOC STRING

/*....................*/


my parser program able to read a line at a time from a file and call
the appropriate VC++ graphics routines such as
line(x,x,x,x),loadbitmap(x,x,x,x)etc..the parameters for this routines
are supplied during runtime.

please give me ur suggestion and way to approach in a algorithm
atleast.becoz this is my univ project.


Expecting from u'll script gurus,
Mahesh (b'lore)

Nice project, but a bit complex for a newbie.

First try to create something that parses the input, even if it does
nothing with it. A recursive descent parser would be adequate, or it might
even be simpler.

Then think how you will store variables if any.

Decide if you execute the script while parsing (execute a line as it's
read) or you parse the whole script first and then execute the stored
version.

Get familiar with the standard containers, you'll use them a lot.

If you have more detailed questions, don't hesitate to ask,

hello M4, I do know how 2 design a parser which excutes scripts. I
tried yesterday on Streaming etc. but parser is still unctouched.
Please provide me a bit of code about parser with example.
With regards,

I don't follow you. You know how to design a parser, so what is the
problem?

This group is about learning the languages C and C++, I get the feeling
you would be better of in a group devoted to parsers or algorihms, but
your problem is not clear so I cannot really tell.
