VISUAL C++
enabled by default; the settings are available in the Settings command of the
project menu. Click the C/C++ tab, then click General in the Category dropdown
list. In the Debug info dropdown list, click Program Database for Edit and
Continue.
Unicode string display
To set your debugger options to display Unicode strings, click the Tools menu,
click Options, click Debug, then check the Display Unicode Strings check box.
Variable value display
Pause the cursor over a variable name in the source code to see its current
value. If it is a structure, click the Eyeglasses icon or press Shift+F9 to bring up
the QuickWatch dialog box or drag and drop it into the Watch window.
Undocking windows
If the Output window (or any docked window, for that matter) seems too
small to you, try undocking it to make it a real window by right-clicking it and
toggling the Docking View item.
Conditional break points
Use conditional break points when you need to stop at a break point only once
some condition is reached—for instance, when a for loop reaches a particular
counter value. To do so, set the break point normally, then bring up the
Breakpoints window (Ctrl+B or Alt+F9). Select the specific break point you just
set, then click the Condition button to display a dialog box in which you specify
the break point condition.
Preloading DLLs
You can preload DLLs that you want to debug before executing the program.
This allows you to set break points up front rather than waiting until the DLL
has been loaded during program execution. To do this, click Project, click Settings,
click Debug, click Category, then click Additional DLLs. Then, click in the
list area to add any DLLs you want to preload.
Changing display formats
You can change the display format of variables in the QuickWatch dialog box or
in the Watch window using the formatting symbols in the following table.
