Re: Use inline member function to refer different levels of classes.

Yes, all files are in my project.

Also, all of these happened at compile time, not at the runtime. Frown | :(

I appreciate your help all the time...

Well, I know that. That's wath I'm talking about in my previous post.

Sorry, but then I can't help anymore. I explained the problem clearly in my previous message, so at least you have some clues to investigate.
Are you absolutely sure that the .cpp file is in your project ? I'm not talking about including the header file with an "include" statement.

Yes pal, this is sure. I've double checked after you ask that pal. Cry | :((

Is it one single project or is it a solution containing several sub-projects ?

Is it a big project ? If no, would it be possible that you send everything to me by mail (only the source and header files and the solution and project files: sln and vcproj if you are using VC2005)? You can send it to cedric_moonen at hotmail dot com.
Put all those files (and only those) in a zip file. I can have a look and see if I can fix the problem.

Thanks pal, it is collection of sub-projects. Actually there is 7 sub-projects. I've done all the things learn until now in a same project to use as a single one. Now the size is over 30MB, even delete all debug folders. I'll try to remove all un-wanted projects and send it to you.

Also I used Visual Studio .Net 2003.

I appreciate your help all the time...

That is probably your problem. This class (the CMsgRecorder) is part of one of your project but you try to use it in another one. The compiler can find the header file of this file but once it needs to link to it, it fails because it is not part of the same project. Am I right or not ?

You cannot do that, you cannot use classes from other projects. It is not because it is in the same solution that you can use everything from everywhere. It is exactly the same as if the projects were not in the same solution. Putting them together is just a matter of convenience, nothing else.

Yes, I think so. Since I used large number of projects, it can be happened. Now first thing I'm going to do is, remove this project from the existing one and test. Let see what I can found.

Issues with std::vector

Is there some limitation on the vector template that I should know about?

I have a vector of 45,000 string pointers. It's a dictionary file Wink | ;)

. Anyway, I need to iterate through these strings checking if more than one definition is present on the same line. Multiple definition are seperated with the '|' character, when I find one I create a new string and push it to the end of the vector. Simple enough you would think.

So, here is my code.

vector< LPENTRY >::iterator vIter = vEntries.begin();
    
    while ( vIter != vEntries.end() )
    {
        LPSTR szEng = strchr( (*vIter)->English, '|' );
    
        if ( szEng != NULL )
        {
            // Create a new entry
            LPENTRY pEntry = new ENTRY;
    
            // Copy the contents ( the struct arranges new memory and copies the strings )
            *pEntry = *vIter;
    
            // Copy the new English
            strcpy_s( pEntry->English, MAX_LINE_LENGTH, &szEng[ 1 ] );
    
            // Shorten the old string
            *szEng = 0x00;
    
            vEntries.push_back( pEntry );
        }
    
        vIter++;
    }

The problem is, when the vector grows to a size of 61447 and when pushing a new value to the end, it causes the iterator to become invalid ( pointing to 0xfeeefeee ). Hence when trying to increase it it triggers a breakpoint. Any ideas what is going wrong?

Firstly, see here[^] for the meaning of 0xfeeefeee.

See here[^] for a description of "iterator invalidation". Here's a quote:

[2] Memory will be reallocated automatically if more than
capacity() - size() elements are inserted into the vector. Reallocation does not change size(),
nor does it change the values of any elements of the vector. It does, however, increase capacity(),
and it invalidates [5] any iterators that point into the vector.

That value of 0xfeeefeee should have given it away. I worked around the issue by throwing out the iterator and used the indexing method instead. Though thanks for the reply Smile | :)

thats all....
if i click a button that should be open....
shall i put instead of str, D:\\Paul.pdf?

Just for tracking the error. Please try like this and let me know the result...

#undef _INC_SHELLAPI<br />
#include <shellapi.h><br />
...<br />
...<br />
...<br />
void CPdf_ExampleView::OnBnClickedButton1()<br />

str = "www.google.com";<br />

Everything looks fine, except you should probably use SW_NORMAL, but this will not be the cause of your problems. What's happening? Are you still getting a compiler error?
