atoi Problem

[makaveliuk]

I have got a really annoying problem that I just cannot solve, look at the following code:

char szCount[20];
memset(szCount, 0, sizeof(szCount));
memcpy(szCount, (void *)strPageCount.GetBuffer(strPageCount.GetLength()), strPageCount.GetLength());
m_iPageCount = atoi(szCount);

The strPageCount is a CString containing a 2 digit+ number, when I copy it, szCount contains all the digits but when I run the atoi() function, it only converts the first character.

I have also tried atoi(strPageCount) which doesn't work and strcpy instead of memcpy and atoi(strPageCount.GetBuffer(strPageCount.GetLength())) and none of those work.

Any ideas?

If you are sure that the first two chars are digits then here is what you have to do:
CString szPageCount="23...";
int m_iPageCount = atoi(szPageCount.Left(2)); // 23
If the szPageCount string contains non digits then it stop at the first one reached.
