Q. How do I interate through an MFC CMap<> ?
A.
// Assuming you have a string -> pointer map like this
typedef CMap< CString, LPCSTR, Node*, Node*> CMapStringToNode;
// Loop through all elements this way:
void interate_thru_cmap(CMapStringToNode &map)
{
CString strJunk;
Node *node;
pos = map.GetStartPosition();
for (;;)
{
if (pos == NULL) break;
map.GetNextAssoc(pos, strJunk, node);
// Do something with node ...
}
}
// STL's map<> is easier to work with.
