"Parse" eventually could be anything you can imagine. Explain what this term means for you. Besides, this new formula "parse flash driver" sounds even worse. Total gibberish.

Please note, if you cannot clearly explain your problem, most probably you won't be helped. So please do your best.

We already understood that you want to parse some text file.

Look at CStdioFile and CString::Tokenize().

Beyond that, without a lot more details from you, I doubt anybody can help much. What part are you stuck on?

I've been doing this 25 years, and that tells me nothing about what you're trying to do. Why are you being so stubborn about explaining what you need help with?

Well, that makes the task for OP easier!

Dear Rajendramaraveni,
did you read the post from GCDEF:

Did you look at these classes (CStdioFile and CString) description in MSDN?

I defined the structure Srec based on S-Record and using CMap(KEY,Srec).
Please kindly how to Implement CMap.
June 11th, 2012, 02:13 AM
VictorN

Re: Parse file in vc++

What CMap do you mean? For example, the MFC CMap template requires 4 "arguments" and is written like

Code:

template< class KEY, class ARG_KEY, class VALUE, class ARG_VALUE >class CMap : public CObject

What about "your" CMap?

Re: Parse file in vc++

struct Srec{
Startcode char;
Record type unsigned short int;
Bytecount unsigned short int;
Address unsigned long;
Data Cstring;
Checksum unsigned short int;
}

CMap <KEY,Srec>
In my CMap what should be the key value?
Basede the key will get the data... I am new to vc++ please...

Please, stop posting such a "pseudo"-code snippets. If you have no idea what CMap is - read about it in MSDN first.
If you"d like to post some code snippet - use Code tags. And, please, read Announcement: Before you post....

Then you have first learn the C++/VC++ and then start with something like "Hello World!" application. :cool:

Re: Parse file in vc++

Why a CMap? If you know you need a map, you'd know what the key should be. If you don't know what to use for the key, you probably don't want a map.

This is getting silly. You're repeating yourself endlessly and ignoring everything people are telling you. Your question still isn't even making sense. If you have no C++ experience at all, a forum can't help you. It doesn't work that way. If you don't understand what people are saying, ask for clarification, or better yet, at least get familiar with the fundamentals of the language, but be prepared to spend some time on it. I, and I think others asked what you need to parse and why you need a map and you didn't respond.

Repeating yourself endlessly isn't working for you. Try something different.

But maybe you'll first answer the question you quoted in your recent post

And also explain a little about the format of ".sx file Motorola ..." and provide information about the length of each field you expect to read from.

You really think that this answers my question? :rolleyes:

In your turn, please do understand that I (or any other person here in this forum) have no chance to help you because you show no will to learn anything as well as answer the questions other people ask you. Endlessly saying please-please improves the situation in no way. You need to start talking technical language to let people help you. To start talking it you need to learn at least the very basic things about the programming language you're trying to use and gain some very basic skills. You might not like that, but you need to stop what you do, immediately, and take some C++ courses and read some books on C++.

Another thing you might not like, but the truth is that nobody here has an intention to make your work for you. Any internet forum works based on a free will of participants. The factor that works most in communities like this is respect to your addressee. When you ask really elementary questions, you show disrespect. And when you never listen to what people tell you, again you show disrespect. And when you talk to people unprofessionally and never even try to improve, you show disrespect. Just think about this.
