visual studio - how to create conditional breakpoint with std::string

Suppose I have this function:

std::string Func1(std::string myString)
{
   //do some string processing 
   std::string newString = Func2(myString)
   return newString;  
}

how do I set a conditional break when newString has a specific value ? (without changing the source)

setting a condition newString == "my value"

didn't work the breakpoints got disabled with an error "overloaded operator not found"

There is a much easier way in Visual Studio 2010/2012.

To accomplish what you are looking for in ANSI use this:

strcmp(newString._Bx._Ptr,"my value")==0 

And in unicode (if newString were unicode) use this:

wcscmp(newString._Bx._Ptr, L"my value")==0 

There are more things you can do than just a compare, you can read more about it here:
