How do I remove an entry from a vector <CString> if I know it's index?

Hi all,

I have the following :
  vector<CString> myVar;
  myVar.push_back("A");
  myVar.push_back("B");
  myVar.push_back("C");

if I want to remove B by its ID, how do I do it?

  myVar.RemoveAt(1);
doesn't exist :-)

Thanks

James

IMO it must be:

> myVar.erase( myVar.begin() + 1 );

since the 'erase' function expects an iterator.

Hope that helps,

the following code snippet should help. Also there is function called clear() which can be called to clear and cleanup all elements of t\he vector
int main ()
{
  unsigned int i;
  vector<unsigned int> myvector;
 
  // set some values (from 1 to 10)
  for (i=1; i<=10; i++) myvector.push_back(i);
  
  // erase the 6th element
  myvector.erase (myvector.begin()+5);
 
  // erase the first 3 elements:
  myvector.erase (myvector.begin(),myvector.begin()+3);
 
  cout << "myvector contains:";
  for (i=0; i<myvector.size(); i++)
    cout << " " << myvector[i];
  cout << endl;
 
  return 0;
}
