My first thought was "$%^&# I calculated the rectangles wrong", so fire up the old viewer, and guess what, the regions are perfect. Without your work I would have spent all night tearing my functions apart trying to find the fault, at least now I know where not to look.

vector<BYTE> vec(1000);
RGNDATA* pData = (RGNDATA*) &vec[0];
vector<BYTE>::size_type cbyBuffer = vec.size();

Why is it that C has a whole bunch of other functions like calloc(), realloc() and _msize()? The latter is what pains me today.

Most of you will say to use a vector,

For example I need to allocate space for a RGNDATA struct which is a little more than a simple array. Allocating the space is no problem, but how is it possible to later find out how much memory was allocated? In C a call to _msize() would do the job, but experience tells me not to mix C and C++ when it comes to memory.

Is there a way to do this other than storing the size when it was allocated?

int *x = new int[345];
printf("You allocated %lu bytes\n", *((unsigned long *) x - 4)); // 1380

CMyDlg dlg;<br />
if (IDOK == dlg.DoModal())<br />
{ // Save button was pressed<br />
    CString val1 = dlg.m_val1;<br />
    // .. and so on<br />
<br />
    m_list.Add (val1); // something like this<br />
}
