But I did initialised pStr:

for (i = 0; i < iCount; i++)
{
    pStr[i] = new char[100];
    m_payeeList.GetText(pItems[i], pStr[i]);

Any reason why you can't use std::string?

You have a memory leak for unexName and you have delegated responsiblity to the caller to free partName.

I try to add something that's larger than that, why does it add it anyways without crashing

The point is you shouldn't pass the pointer out, instead the caller should pass a buffer in. The caller has an option of creating a buffer on the heap or on the stack. If the caller creates the buffer on the heap using malloc, then he would also know that he has to free it.
