characters?
Word means a 16-bit integer, not a string at all
Maybe you need CMapStringToPtr, unique forbidden character is null (ascii 0)

I think I am doing a different mistake
Inside loop, I remove some keys. I think this is the problem. Is it?
Eugene
    pCurVal= myMap.PGetFirstAssoc( );
    while (pCurVal != NULL)
    {
           pCurVal= myMap.PGetNextAssoc(pCurVal);
           if(OnSomeCondition){
            delete myMap.pointer
             myMap.RemoveKey("xxx")
           }
    }
    if(myMap.IsEmpty())myMap.RemoveAll()

So far, that looks ok. What error are you getting and what is the original code?

You have not exposed your problem. Error message? Undesired result?
In you code I see something strange:

while (pCurVal != NULL)
    {
           if(OnSomeCondition){
            delete myMap.pointer
             myMap.RemoveKey("xxx")
           }
           pCurVal= myMap.PGetNextAssoc(pCurVal);  // notice the position of this line
    }
