POCan I set a conditional breakpoint in base class method which triggers only if it's an instance of specific derived class?

    <p>Let's say I have some base class A and two derived classes B and C. Class A has some method called f(). </p> <p>Is there a way to set a conditional breakpoint in A::f() in visual studio which will be hit only when my 'this' is actually an instance of class C?</p> <p>For example</p> <pre><code> void A::f() { some code and a breakpoint } void foo(A* a) { a->f(); } void bar() { A a; B b; C c; foo(&a); // breakpoint isn't hit foo(&b); // breakpoint isn't hit foo(&c); // breakpoint is hit }</code></pre> <p>I've managed to achieve it by testing virtual table pointer in breakpoint's condition but there's got to be a better(more easy) way.</p> <p>Thanks in advance.</p> <p>EDIT: Modifying source code as was suggested in comments is not kind of a solution I'm looking for. It has to be done only by means of VC++ debugger.</p>

    1. COoverride the method in the derived class to simply call the base class and put your breakpoint there?

    2. CO@AJG85 - yes, but it's possible that the binary cannot be modified. fwiw I don't think conditional BPs allow this to be done.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
