Hi everyone, I'm new to this forum and it has helped me a lot with the project I am currently working on.

Using VS2008 and created an MFC dialog based application. I just started learning C++ and am finding it difficult to solve this problem.

What I'm trying to do is store a vector into a binary file and then read the binary file back into a vector. I have 3 strings that I am storing into an object and then create a vector of these objects. Each element in the vector therefore consists of 3 strings (date, article1, article2). My code is like this:

class Article 
	char date_time[19];
	CString article1;
	CString article2;

Write to file:

vector<Article> articles;
Article articleItems; 
strcpy(articleItems.date_time, buf); 
articleItems.article1 = n_Articles;
articleItems.article2 = w_Articles; 


ofstream articleFile;
articleFile.open("articles.dat", ios::out|ios::binary|ios::app);
articleFile.write(reinterpret_cast<char *>(&articles), sizeof(articles));

Read from file:

vector<Article> articleItems; 
ifstream articles; 
articles.open("articles.dat", ios::in|ios::binary);
articles.read(reinterpret_cast<char *>(&articleItems), sizeof(articleItems));

Writing seemed to create a file, but then reading produced no results (nothing in the vector). If I wrote 'articleItems' object to the file instead of the vector, then I could read this properly if I was reading it into another object of type 'Article'. However when exiting the application, the program would crash with a 'Access violation error' and the data in the file would get corrupted? (won't display properly if I tried to read the same file again).

I had to change date_time from a string to char because it wouldn't display properly when reading the file (weird characters - if a string is used, instead of char).

I'm trying to create a vector so I could search for articles by date and then pull out these articles and display them, but having problems with saving vectors to files!

Hope you can help, thanks!

Thanks, I'll look into it.
