The debuggers uses a pseudoregister called ERR for this purpose. The second watch will clear the pseudo register after the display of the current value, so the next step or step over you do gives you the time for that action The installer log tries several different methods to retrieve the same url and fails on all attempts and gives up.

Disadvantages Requires C++ objects to manage resources such as memory or file handles. If the method succeeds, place the next method call inside the if block.

The following example code shows the wrong way and the right way to test for the success of a function call. Debug checked casts If you want maximum safety, you should always use dynamic_cast. For every method or function that returns an HRESULT, check the return value before proceeding. navigate here either set it to a block before the section you want to edit, or, step out of the function, then step back in.

Calling Release on an invalid pointer will crash the program (or worse), so you must initialize all pointers to NULL and check whether they are NULL before releasing them. How can you get the error value without recompiling and reproducing the failure? Disadvantages Some people find deep nesting hard to read.

You'll now get reports on how long a compile took in your Build window.
