Question

I want to add a breakpoint condition to my code in VC++ Express 2005, so that the breakpoint only triggers if a local variable meets a specified criteria. e.g.

bool my_test(UIDList test_list) {     foo(test_list);     bar(test_list); // I have a breakpoint here, but only want it to trigger if test_list.Length() > 0     print(test_list); } 

Having right-clicked on my breakpoint and selected ‘Condition…’ I have found a dialog that appears to do what I want, however anything I try typing into the text field results in the following error:

Unable to evaluate the breakpoint condition: CX0052: Error: member function not present

I tried the help documentation, but I couldn’t find my answer. I’m hoping someone experienced in VC++ might be able to point me in the right direction…

I have previously tried upgrading to a more recent version of VC++ Express, but the project did not import cleanly. Due to the complexity of the project and my current time scales I can’t consider upgrading as a solution at this point.

Answer 1

use the DebugBreak(); function:

bool my_test(UIDList test_list) {     foo(test_list);     if (bar(test_list) /* or whatever check :) */) // I have a breakpoint here, but only want it to trigger if test_list.Length() > 0         DebugBreak();     }     print(test_list); } 

Or you can always use assert(expression)

bool my_test(UIDList test_list) {     foo(test_list);     bar(test_list);     assert(test_list.Length() > 0); // will break here     print(test_list); }
