Hello,

I have a simple console application in C++ whose main() does the
following...

char* s = "Hello";
printf("String is %s\n",s);
return 0;

I set a conditoinal breakpoint on the line with the printf, the condition is
s == "Hello".
The breakpoint is not hit and execution continues without stopping at the
breakpoint.
How can i make this happen? Is there something wrong with the condition i
give?
Incidentally when the condition involves an int variable the break point is
hit! Can we not use strings as conditions?

I'm using VS.Net 7.0.9466

Thanks in advance
Vivek

Correct, you can't use strings the way you are doing it. The equality
operator is not going to work on a string (especially not a char *.) What
you'd need to be able to do is use strcmp() in the BP condition. But
unfortunately, it won't work. This is something we hope to fix in a future
version.

In the meantime, what you need to do to work around this is to test the
value of each character inthe condition:
s[0] == 'H' && s[1] == 'e' && s[2] == 'l' && s[3] == 'l' && s[4]== 'o'
It isn't pretty but it does work.
