Debug Assertion Failure?

[Gone With Wind]

I am a novice of C++. I write the following code to append strings to
a Combox (m_RibNum). This control component is on a PropertyPage
hosted on a PropertySheet.

int i;
char buffer[10];
CString s
for (i=0;i<5;i++)
{
itoa(i+1,buffer,10);
s=*buffer;
sheet.m_RibTypeEdit.m_RibNum.AddString((LPCTSTR)s);
}

When I debug this code, Debug Assertion Failure occured. Could anybody
tell me what's wrong in my code please?

You'd have better luck on a windows group, none of those functions or
classes are standard C++.

As others have already pointed out, there's not much C++ in
there to go on. Just guessing about what the code does,
wouldn't something like:

for ( int i = 0 ; i < 5 ; ++ i ) {
std::istringstream s ;
s << i ;
shee.m_RibTypeEdit.m_RibNum.AddString(
toCString( s.str() ) ) ;
}

be more what you are looking for. (I'm not too sure about how
to convert a string to a CString, but if CString is some sort of
text string, there's a good chance that CString( s.str().c_str() ), or
even just CString( s.str() ) would do the trick here.)

One thing that's wrong is that this code is not copied and pasted, so all we
know is that it's certainly not the exact code you have problems with.

CString is not a standard C++ class, it's a class defined by Microsoft.

Presumably your code could "work" if you changed it as follows:

    for( int i = 1;  i <= 5;  ++i )
    {
        char buffer[10];
        itoa( i, buffer, 10 );
        sheet.m_RibTypeEdit.m_RibNum.AddString( buffer );
    }

But it might be that e.g. it's the "sheet" variable that's causing problems.
